Medical Mutual Gains Fast Access to z/OS Log Data via Splunk and Ironstream

June 3, 2016

Running Syncsort’s Ironstream and leveraging Splunk Enterprise, Medical Mutual of Ohio has now implemented mainframe security in real time through the Splunk® Enterprise platform. One goal is to help protect customer information stored in DB2 from unauthorized access. Syncsorts’s Ironstream, a utility, collects and forwards z/OS log data, including security data, to Splunk Enterprise and Splunk Enterprise Security.

“We’ve always had visibility. Now we can get it faster, in real time directly from the mainframe,” said the insurer’s enterprise security supervisor. Previously, the company would do a conventional data transfer, which could take several hours. The new approach, sometimes referred to as a big iron-to-big data strategy, now delivers security log data in near real time. This enables the security team to correlate all the security data from across the enterprise to effectively and quickly gain visibility into user-authentication data and access attempts tracked on the mainframe. And they can do it without needing specialized expertise or different monitoring systems for z/OS.

Real-time analytics, including real-time predictive analytics, are increasingly attractive as solutions for the growng security challenges organizations are facing. These challenges are due, in large part, to the explosion of transaction activity driven by mobile computing, and soon, IoT, and Blockchain, most of which eventually finds its way to the mainframe. All of these present immediate security concerns and require fast, nearly instant security decisions. Even cloud usage, which one would expect to be mainstream in enterprises by now, often is curtailed due to security fears.

With the Ironstream and Splunk combination, Medical Mutual Medical Mutual can see previously slow-to-access mainframe data alongside other security information it was already analyzing in Splunk Enterprise. Splunk Enterprise enables a consolidated enterprise-wide view of machine data collected across the business, which makes it possible to correlate events that might not raise suspicion alone but could be indicative of a threat when seen together.

The deployment proved to be straightforward. Medical Mutual’s in-house IT team set it up in a week with Syncsort answering deployment questions to assist. Although there are numerous tools to capture log data from the mainframe, the insurer chose to go with the Splunk-Ironstream combination because it already was using Splunk in house for centralized logging. Adding mainframe security logs was an easy step. “This was affordable and it saved us from having to learn another product,” the security supervisor added. Medical Mutual runs a z13, model 409 with Ironstream.

According to the announcement, by having Ironstream leverage z/OS log data via Splunk Enterprise, Medical Mutual has enables the organization to:

  • Track security events and data from multiple platforms including IBM z/OS mainframes, Windows and distributed servers and correlate the information in Splunk Enterprise for better security.
  • Diagnose and respond to high severity security issues more quickly since data from across the entire enterprise is being monitored in real time.
  • Provide monthly and daily reporting with an up-to-the-minute account of unusual user activity.
  • Detect security anomalies and analyze their trends – the cornerstone of Security Information and Event Management (SIEM) strategies.

Real time monitoring with analytics has proven crucial for security. You can actually detect fraud while it is taking place and before serious damage is done. It is much harder to recoup loses hours, days, or, what is often the case, months later.

The Splunk platform can handle massive amounts of data from different formats and indexes and decipher and correlate security events through analytics. Ironstream brings the ability to stream mainframe security data for even greater insights, and Ironstream’s low overhead keeps mainframe processing costs low.

To try the big iron-to-big data strategy organizations can download a free Ironstream Starter Edition and begin streaming z/OS Syslog data into Splunk solutions. Unlike typical technology trials, the Starter Edition is not time-limited and may be used in production at no charge. This includes access to the Ironstream applications available for download on Splunkbase.

New Software Pricing for IBM z13

February 6, 2015

Every new mainframe causes IBM to rethink its pricing. This makes sense because mainframe software licensing is complex. The z13 enables different workloads and combinations of uses that merit reexamining the software licensing. But overall, IBM is continuing its strategy to enhance software price/performance with each generation of hardware. This has been the case for as long as DancingDinosaur has been covering the mainframe. (click graphic below to enlarge)

 IBM z13 technology update pricing

DancingDinsosaur along with other mainframe analysts recently listened to Ray Jones, IBM Vice President, z Systems Sales go through the new z13 software pricing. In short, expect major new structural enhancements coming in the first half of 2015. Of particular interest will be two changes IBM is instituting:

  1. IBM Collocated Application Pricing (ICAP), which lets you run your systems the way that make sense in your organization
  2. Country Multiplex Pricing, an evolution of Sysplex pricing that allows for greater flexibility and simplicity which treats all your mainframes in one country as a single sysplex.

Overall, organizations running the z under AWLC should see a 5% discount on average.

But first let’s take a moment to review AWLC (Advanced Workload License Charge). This monthly program from the start has been intended to allow you to grow hardware capacity without necessarily increasing software charges. Most organizations under AWLC can grow hardware capacity without necessarily increasing software charges. In general you’ll experience a low cost of incremental growth and you can manage software cost by managing workload utilization and deployment across LPARs and peak hours.

A brief word about MSU. DancingDinosaur thinks of MSU as mainframe service unit. It is the measurement of the amount of processing or capacity of your mainframe. IBM determines the MSU rating of a particular mainframe configuration by some arcane process invisible to most of us. The table above starts with MSU; just use the number IBM has assigned your z configuration.

OK, now we’re ready to look at ICAP pricing. IBM describes ICAP as the next evolution of z Systems sub-capacity software pricing. ICAP allows workloads to be priced as if in a dedicated environment although technically you have integrated them with other workloads. In short, you can run your systems and deploy your ICAP workloads the way you want to run them. For example, you might want to run a new anti-fraud app or a new instance of MQ and do it on the same LPAR you’re running some other workload.

ICAP is for new workloads you’re bringing onto the z. You have to define the workloads and are responsible for collecting and reporting the CPU time. It can be as simple as creating a text file to report it. However, don’t rush to do this; IBM suggested an ICAP enhancement to the MWRT sub-capacity reporting tool will be coming.

In terms of ICAP impact on pricing, IBM reports no effect on the reported MSUs for other sub-capacity middleware programs (adjusts MSUs like an offload engine, similar to Mobile Workload Pricing for z/OS). z/OS shops could see 50% of the ICAP-defining program MSUs will be removed, which can result in real savings. IBM reports that ICAP provides a price benefit similar to zNALC for z/OS, but without the requirement for a separate LPAR. Remember, with ICAP you can deploy your workloads where you see fit.

For Country Multiplex Pricing a country multiplex to IBM is the collection of all zEnterprise and later machines in a country, and they are measured like one machine for sub-capacity reporting (applicable to all z196, z114, zEC12, zBC12, and z13 machines). It amounts to a new way of measuring and pricing MSUs, as opposed to aggregating under current rules. The result should be flexibility to move and run work anywhere, the elimination of Sysplex pricing rules, and the elimination of duplicate peaks when workloads move between machines.

In the end, the cost of growth is reduced with one price per product based on growth anywhere in the country. Hardware and software migrations also become greatly simplified because Single Version Charging (SVC) and Cross Systems Waivers (CSW) will no longer be relevant.  And as with ICAP, a new Multiplex sub-capacity reporting tool is coming.

Other savings also remain in play, especially the z/OS mobile pricing discounts, which significantly reduces the level at which mobile activity is calculated for peak load pricing. With the expectation that mobile activity will only grow substantially going forward, these savings could become quite large.

IBM Ends 2014 with Flurry of Outsourcing, Cloud Activity

January 4, 2015

Happy New Year. There is much to look forward to in 2015. At the least it probably is time for IBM to rev the System z. The zEnterprise EC12 was introduced in Aug. 2012. You should expect a new machine this year.

ibm cloud centers

IBM ended the year with a flurry of deals involving outsourcing in various forms, hybrid clouds, and the expansion its cloud centers globally. The company made it clear throughout this past difficult year that its focus will be on cloud computing, analytics, and mobile, and that’s what they did. DancingDinosaur will leave to the Wall St. analysts the question of whether the deals represent enough action at a sufficient margin.

IBM believes its future rides on the cloud. To that end it writes: Enterprise cloud deployments, specifically hybrid cloud, are growing at a significant rate.  According to Gartner, nearly half of all enterprises will have a hybrid cloud deployed by 2017.  Chief among the driving forces behind the adoption of cloud computing worldwide, including hybrid cloud, are requirements for businesses and governments to store certain data locally to comply with data residency regulations, as well as a growing desire for startups to expand their businesses globally.  IBM estimates about 100 nations and territories have adopted laws that dictate how governments and private enterprises handle personal data.

The expansion of the company’s global footprint of its cloud centers, now up to 40 locations, represents an effort to capitalize on cloud interest. Since the start of November, the company announced more than $4 billion worth of cloud agreements with major enterprises around the world. These include Lufthansa, ABN AMRO, WPP, Woox Innovations, Dow Water, and Thomson Reuters. Some of these, you will notice, are mainframe shops. DancingDinosaur is assuming they are augmenting their z with a hybrid cloud, not replacing it.

In addition, there are new organizations, referred to by IBM as born-on-the-web innovators, which are building their business on the IBM Cloud. Since November, IBM has announced wins with Diabetizer and Preveniomed, Hancom, Musimundo, and Nubity. Collectively these wins reflect IBM’s ability to deliver a full range of services through the cloud. Some of these are analytics-driven wins.

An interesting recently announced win was Westfield Insurance, which began working with IBM to transform their claims operations. To this end, Westfield is looking at business analytics to increase flexibility, operational efficiency, and effectiveness while enabling the company to keep pace with its evolving customer base and business growth. When DancingDinosaur last checked, Westfield was a z196 shop running DB2.

As IBM reports, leading insurers are leveraging cloud, analytics and social technologies to stay ahead of their competition. Specifically, more than 60% of identified leading insurers are focused on advanced analytics to improve their claims handling in order to streamline processes and increase customer satisfaction. Westfield’s multi-year claims handling transformation initiatives, including process, organizational and technology changes, focus on using data and analytics to better serve customers.

For Westfield, IBM developed a new protocol to migrate data for use with predicative models, built simulation models to evaluate bottlenecks in the claims process, and designed a strategy for expedited workflow.  This simulation helped expedite organizational changes. The new claims system will also utilize a suite of IBM counter-fraud capabilities to detect suspicious activity.

In addition, IBM helped Westfield optimize its current claims handling process to provide a seamless, fully-integrated customer experience. Westfield’s claims system with Guidewire is now consolidated to ensure efficient operations across its network.

To further drive its cloud business IBM simplified its cloud contract with a goal of reducing the complexity and speeding the signing of cloud agreements. The result is a standard, two-page agreement that replaces the previous longer, more complex contracts, which typically entailed long negotiations and reviews before a deal was signed. By comparison, its cloud competitors require customers to review and commit to more complex contracts that commonly are at least five times longer and also incorporate terms and conditions from other websites, IBM reports.

Citing leading industry analyst firms, IBM claims global leadership in cloud computing with a diverse portfolio of open cloud solutions designed to enable clients for the hybrid cloud era. IBM has helped more than 30,000 cloud clients around the world. It boasts of over 30,000 cloud clients, invested more than $7 billion since 2007 in 17 acquisitions to accelerate its cloud initiatives, and holds more than 1,560 cloud patents. IBM also processes more than 5.5 million client transactions daily through its public cloud.

IBM’s initiatives in cloud computing will not diminish its interest in the System z enterprise cloud platform. To the contrary a recent IBM analysis shows the z enhancing the economic advantages of the cloud: a business scaling up to about 200 virtual machines (VM) gets far more efficient and economical results by using the Enterprise Linux Server as an enterprise cloud than with a virtualized x86 or public-cloud model. And the deal gets even better if you acquire the Enterprise Linux Server under either the Solution Edition program for Enterprise Linux  or the System z Solution Edition for Cloud Computing.

Software Licensing for IBM System z Distributed Linux Middleware

October 10, 2014

DancingDinosaur can’t attend a mainframe conference without checking out at least one session on mainframe software pricing by David Chase, IBM’s mainframe pricing guru. At IBM Enterprise2014, which wraps up today, the topic of choice was software licensing for Linux middleware. It’s sufficiently complicated to merit an entire session.

In case you think Linux on z is not in your future, maybe you should think again.  Linux is gaining momentum in even the largest z data centers. Start with IBM bringing new apps like InfoSphere, BigInsights (Hadoop), and OpenStack to z. Then there are apps from ISVs that just weren’t going to get their offerings to z/OS. Together it points to a telltale sign something is happening with Linux on z. And, the queasiness managers used to have about the open source nature of Linux has long been put to rest.

At some point, you will need to think about IBM’s software pricing for Linux middleware. Should you find yourself getting too lost in the topic, check out these links recommended by Chase:

To begin, software for Linux on z is treated differently than traditional mainframe software in terms of pricing. With Linux on z you think in terms of IFLs.  The quantity of IFLs represent the number of Linux engines subjected to IBM’s IPLA-based pricing.

Also think in terms of Processor Value Units (PVUs) rather than MSUs. For a pricing purposes, PVUs are analogous to MSUs although the values are different. A key point to keep in mind: distributed PVUs for Linux are not related to System z IPLA value units used for z/VM products. As is typical of IBM, those two different kinds of value units are NOT interchangeable.

Chase, however, provides a few ground rules:

  • Dedicated partition
    • Processors are always allocated in whole increments
    • Resources are only moved between partitions “explicitly” (e.g. by an operator or a scheduled job)
  • Shared pool:
    • Pool of processors shared by partitions (including virtual machines)
    • System automatically dispatches processor resources between partitions as needed
  • Maximum license requirements
  • Customer does not have to purchase more licenses for a product than the number of processors on the machine (e.g. maximum DB2 UDB licenses on a 12-way machine is 12)
    • Customer does not have to purchase more “shared pool” licenses for a product than the number of processors assigned to the shared pool (e.g. maximum of 7 MQSeries licenses for a shared pool with 7 processors). Note: This limit does not affect the additional licenses that might be required for dedicated partitions.

With that, as Chase explains it, Linux middleware pricing turns out to be relatively straightforward, determined by:

  • Processor Value Unit (PVU) rating for each kind of core
  • Any difference for different processor technologies (p, i, x, z, Sun, HP, AMD, etc—notice that the z is just one of many choices, not handled differently from the others
  • Number of processor cores which must be licensed (z calls them IFLs)
  • Price per PVU (constant per product, not different based upon technology)

Then it becomes a case of doing the basic arithmetic. The formula: # of PVUs x the # of cores required x the value ($) per core = your total cost.  Given this formula it is to your advantage to plan your Linux use to minimize IFLs and cores. You can’t do anything about the cost per PVU.

Distributed PVUs are the basis for licensing middleware on IFLs and are determined by the type of machine processor. The zEC12, z196, and z10 are rated at 120 PVUs. All others are rated at 100 PVUs. For example, any distributed middleware running on Linux on z this works out to:

  • z114—1IFL, 100 PVUs
  • z196—4IFLs, 480 PVUs
  • zEC12—8 IFLs, 960 PVUs

Also, distributed systems Linux middleware offerings are eligible for sub-capacity licensing. Specifically, sub-capacity licensing is available for all PVU-priced software offerings that run on:

  • UNIX (AIX, HP-UX, and Sun Solaris
  • i5/OS, OS/400
  • Linux (System i, System p, System z)
  • x86 (VMware ESX Server, VMware GSX Server, Microsoft Virtual Server)

IBM’s virtualization technologies also are included in Passport Advantage sub-capacity licensing offering, including LPAR, z/VM virtual machines in an LPAR, CPU Pooling support introduced in z/VM 6.3 APAR VM65418, and native z/VM (on machines which still support basic mode).

And in true z style, since this can seem more complicated than it should seem, there are tools available to do the job. In fact Chase doesn’t advise doing this without a tool. The current tool is the IBM License Metric Tool V9.0.1. You can find more details on it here.

If you are considering distributed Linux middleware software or are already wrestling with the pricing process, DancingDinosaur recommends you check out Chase’s links at the top of this piece. Good luck.

IBM-Apple Deal Enhanced by New z/OS Pricing Discounts

July 25, 2014

In the spring, IBM announced, almost as an aside, new pricing discounts for z/OS mobile transactions. At the time, it didn’t seem like a big deal. But IBM’s more recent announcement of its exclusive mobile partnership with Apple, covered by DancingDinosaur here, suddenly gives it much bigger potential.

The plan is to create apps that can transform specific aspects of how businesses and employees work using iPhone and iPad, allowing companies to achieve new levels of efficiency, effectiveness and customer satisfaction. At the backend will be the mainframe.

Already zEnterprise shops, especially banks and financial services firms, are reporting growth in the volume of transactions that originate from mobile devices. The volume of these mobile-originated transactions in some cases is getting large enough to impact the four-hour peak loads that are used in calculating monthly costs.

Here’s the problem: you put out a mobile app and want people to use it. They do, but much of the workload being generated does not directly produce revenue. Rather, they are requesting data or checking invoices and balances. Kind of a bummer to drive up monthly charges with non-revenue producing work.

That’s where the new pricing discounts for z/OS mobile workloads come in. The new pricing reduces the impact of these mobile transactions on reported LPAR MSUs. Specifically, the Mobile Workload Pricing Reporting Tool (MWRT) will subtract 60% of the reported Mobile MSUs from a given LPAR in each hour, adjusting the total LPAR MSU value for that hour. Think of this as just a standard SCRT report with a discount built in to adjust for mobile workload impact.

So, what does that translate into in terms of hard dollar savings? DancingDinosaur had a private briefing with two IBMers who helped build the tool and asked that question. They are only in the earliest stages of getting actual numbers from users in the field; the tool only became available June 30.  Clearly the results depend on how many mobile transactions you are handling in each reporting hour and how you are handling the workloads.

There is a little work involved but the process won’t seem intimidating to mainframe shops accustomed to IBM’s monthly reporting process. Simply record mobile program transaction data, including CPU seconds, on an hourly basis per LPAR, load the resulting data file into the new tool, MWRT, each month using the IBM-specified CSV format, and run MWRT, submitting the results to IBM each month. It replaces the SCRT process.

The MWRT will function like a partial off-load from a software pricing perspective. When an LPAR value is adjusted, all software running in the LPAR will benefit from lower MSUs. The tool will calculate the monthly MSU peak for a given machine using the adjusted MSU values.

This brings us back to the hard dollar savings question. The answer: probably not much initially unless your mobile apps already generate a sizeable proportion of your peak transaction volume. But jump ahead six months or a year when the IBM-Apple partnership’s new iOS made-for-business apps are gaining traction your mobile transaction volume could be climbing substantially each month. At that point, savings of hundreds of thousands of dollars or more seem quite possible.

Of course, the new applications or the entire partnership could be a bust. In that case, you will have burned some admin time for a one-time set up. You’ll still experience whatever normal transaction growth your current mobile apps generate and collect your discounted MSU charges. Unless the big IT analysis firms are dead wrong, however, mobile transactions are not going away. To the contrary, they will only increase. The bottom line: negligible downside risk while the upside gain could be huge.

Hope to see you at IBM Enterprise 2014 in Las Vegas, Oct. 6-10. DancingDinosaur is Alan Radding. Follow him on Twitter, @mainframeblog and at



Enterprise 2013 Details System z and Power Technology and New Capabilities

October 25, 2013

IBM announced a lot of goodies for z and Power users at Enterprise 2013 wrapping up in Orlando today. There were no blockbuster announcements, like a new z machine—we’re probably 12-18 months away from that and even then the first will likely focus on Power8—but it brought a slew of announcements nonetheless. For a full rundown on what was announced click here.

Cloud and analytics—not surprisingly—loom large. For example, Hadoop and a variety of other capabilities have been newly cobbled together, integrated, optimized, and presented as new big data offerings or as new cloud solutions.  This was exemplified by a new Cognos offering for CFOs needing to create, analyze and manage sophisticated financial plans that can provide greater visibility into enterprise profitability or the lack thereof.

Another announcement featured a new IBM Entry Cloud Configuration for SAP on zEnterprise. This is a cloud-enablement offering combining high-performance technology and services to automate, standardize and accelerate day-to-day SAP operations for reduced operational costs and increased ROI. Services also were big at the conference.

Kicking off the event was a dive into data center economics by Steve Mills, Senior Vice President & Group Executive, IBM Software & Systems. Part of the challenge of optimizing IT economics, he noted, was that the IT environment is cumulative. Enterprises keep picking up more systems, hardware and software, as new needs arise but nothing goes away or gets rationalized in any meaningful way.

Between 2000 and 2010, Mills noted, servers had grown at a 6x rate while storage grew at a 69x rate. Virtual machines, meanwhile, were multiplying at the rate of 42% per year. Does anyone see a potential problem here?

Mills’ suggestion: virtualize and consolidate. Specifically, large servers are better for consolidation. His argument goes like this: Most workloads experience variance in demand. But when you consolidate workloads with variance on a virtualized server the variance of the sum is less due to statistical multiplexing (which fits workloads into the gaps created by the variances). Furthermore, the more workloads you can consolidate, the smaller the variance of the sum. His conclusion: bigger servers with capacity to run more workloads can be driven to higher average utilization levels without violating service level agreements, thereby reducing the cost per workload. Finally, the larger the shared processor pool is the more statistical benefit you get.

On the basis of statistical multiplexing, the zEnterprise and the Power 795 are ideal choices for this. Depending on your workloads, just load up the host server, a System z or a big Power box, with as many cores as you can afford and consolidate as many workloads as practical.

Mills’ other cost savings tips: use flash to avoid the cost and complexity of disk storage. Also, eliminate duplicate applications—the fewer you run, the lower the cost. In short, elimination is the clearest path to saving money in the data center.

To illustrate the point, Jim Tussing from Nationwide described how the company virtualized and consolidated 60% on their 10,500 servers on a few mainframes and saved $46 million over five years. It also allowed the company to delay the need for an additional data center for 4 years.

See, if DancingDinosaur was an actual data center manager it could have justified attendance at the entire conference based on the economic tips from just one of the opening keynotes and spent the rest of the conference playing golf. Of course, DancingDinosaur doesn’t play golf so it sat in numerous program sessions instead, which you will hear more about in coming weeks.

Social Business and Linux on System z at Enterprise 2013

October 17, 2013

The Enterprise 2013 conference next week in Orlando is sold out! However, you can still participate and learn from the session through Livestream, which starts Monday morning (8am ET) with two IBM senior VPs; Tom Rosamilia, followed by Steve Mills. On Tuesday Livestream sessions start at 10:30am ET. Check out the full Livestream schedule here.

Let’s expand on the social business topics to be covered at the conference. Building a Social Environment in an Enterprise Private Cloud looks at the advantages of building a social environment in an on-premise private cloud, exploiting System z where practical. The hybrid System z models seem particularly well suited for this, and the TCO should be quite favorable. Daily Business can Profit from Social Networks for System z looks at how to exploit social on the z to keep current with news and events of importance to the organization and its customers through Twitter and other social networks. Finally, Gaining Competitive Advantage with Social Business separates the social hype from the facts. The session keys in on utilizing social business relationships to help you achieve competitive advantages.

DancingDinosaur has long considered Linux on z as the single most important thing IBM did to save the mainframe from a future as a niche product serving mainly big banks and financial services firms. Today, the mainframe is the center of a hybrid computing world that can do anything business strategists want to do—mobile, cloud, open systems, Linux, Windows. Linux, the key to that, has been slow to catch on, but it is steadily gaining traction. At Enterprise 2013 you can see, to paraphrase a movie title starring Clint Eastwood; The Good, the Great, and the Ugly of Linux on System z.

Linux on System z: Controlling the Proliferating Penguin presents Mike Riggs, Manager of Systems and Database Administration at the Supreme Court of Virginia, sharing his experiences leveraging the power of Linux on System z by utilizing WebSphere, DB2, Oracle, and Java applications in concert with the longstanding success of z/VM, z/VSE, CICS applications, and other platform systems. He will explain how a funds-limited judicial branch of a state government is leveraging all possible resources to manage, grow, and support statewide judicial application systems.

What’s New with Linux on System z provides an overview of Linux on System z. It will show Linux as a very active open source project and offer insight into what makes Linux so special. It also looks at both the latest and as well as upcoming features of the Linux kernel and what these features can do for you.

From there, you can attend the session on Why Linux on System z Saves $$, which will help you build the business case for Linux on z. The presenter, Buzz Woeckener, Director of IT at Nationwide Insurance, will pepper you with facts, disprove some myths, and help you understand why Linux on System z is one of the best values in the marketplace today. DancingDinosaur has written on Nationwide’s Linux on z experience before; it is a great story.

Finally, here’s the ugly: Murphy’s Law Meets VM and Linux on System z. Murphy’s law observes that whatever can go wrong possibly (or probably, depending on your level of pessimism) will go wrong. This can also be the case in some unfortunate Linux on System z and z/VM proof of concepts or improperly configured production systems. Having been called into a number of these situations over the last couple of years, the speaker brings a lot of experience handling these problems. Where some sessions highlight successes, this one will present stories from the battlefield on what it took to get these projects back on track. It will show the mistakes and draw the lessons learned.

Plus there is networking, security, systems management, big data and analytics, development, and more. For those lucky enough to get space, you won’t be at a loss for what to do next. DancingDinosaur will there Sunday through Thursday. If you see me, please feel welcome to introduce yourself.

Enterprise 2013—System z Storage, Hybrid Computing, Social and More

October 10, 2013

The abstract for the Enterprise 2013 System z program runs 43 pages. Haven’t tallied the number of sessions offered but there certainly are enough to keep you busy for the entire conference (Oct. 20-25, in Orlando, register now) and longer.

Just the storage-related sessions are wide ranging, from  DFSM, which DancingDinosaur covered a few weeks back following the SHARE Boston event here, to the IBM Flash portfolio, System z Flash Express, dynamically provisioning Linux on z storage, capacity management, and more. For storage newcomers, there even is a two-part session on System z Storage Basics.

A storage session titled the Evolution of Space Management looks interesting.  After the advent of System Managed Storage (SMS), the mainframe went decades without much change in the landscape of space management processing. Space management consisted of the standard three-tier hierarchy of Primary Level 0 and the two Migration tiers, Migration Level 1 (disk) and Migration Level 2 (tape).This session examines recent advances in both tape and disk technologies that have dramatically changed that landscape and provided new opportunities for managing data on the z. Maybe they will add a level above primary called flash next year. This session will cover how the advances are evolving the space management hierarchy and what to consider when determining which solutions are best for your environment.

IBM has been going hog-wild with flash, the TMS acquisition playing no small part no doubt. Any number of sessions deal with flash storage. This one, IBM’s Flash Portfolio and Futures, seems particularly appealing. It takes a look at how IBM has acquired and improved upon flash technology over what amounts to eight generations technology refinements.  The session will look at how flash will play a major role across not only IBM’s storage products but IBM’s overall solution portfolio. Flash technology is changing the way companies are managing their data today and it is changing the way they understand and manage the economics of technology. This session also will cover how IBM plans to leverage flash in its roadmap moving forward.

Hybrid computing is another phenomenon that has swept over the z in recent years. For that reason this session looks especially interesting, Exploring the World of zEnterprise Hybrid: How Does It Work and What’s the Point? The IBM zEnterprise hybrid system introduces the Unified Resource Manager, allowing an IT shop to manage a collection of one or more zEnterprise nodes, including an optionally attached zBX loaded with blades for different platforms, as a single logical virtualized system through a single mainframe console. The mainframe can now act as the primary point of control through which data center personnel can deploy, configure, monitor, manage, and maintain the integrated System z and zBX blades based on heterogeneous architectures but in a unified manner. It amounts to a new world of blades and virtual servers with the z at the center of it.

Maybe one of the hardest things for traditional z data center managers to get their heads around is social business on the mainframe. But here it is: IBM DevOps Solution: Accelerating the Delivery of Multiplatform Applications looks at social business and mobile along with big data, and cloud technologies as driving the demand for faster approaches to software delivery across all platforms, middleware, and devices. The ultimate goal is to push out more features in each release and get more releases out the door with confidence, while maintaining compliance and quality. To succeed, some cultural, process, and technology gaps must be addressed through tools from Rational.

IBM has even set itself up as a poster child for social business in another session, Social Business and Collaboration at IBM, which features the current deployment within IBM of its social business and collaboration environments. Major core components are currently deployed on System z. The session will look at what IBM is doing and how they do it and the advantages and benefits it experiences.

Next week, the last DancingDinosaur posting before Enterprise 2013 begins will look at some other sessions, including software defined everything and Linux on z.

When DancingDinosaur first started writing about the mainframe over 20 years ago it was a big, powerful (for the time), solid performer that handled a few core tasks, did them remarkably well, and still does so today. At that time even the mainframe’s most ardent supporters didn’t imagine the wide variety of things it does now as can be found at Enterprise 2013.

Mantissa z86VM Virtualization Leverages IBM zEC12 and z/VM

September 19, 2013

Jim Porell, formerly an IBM Distinguished Engineer with hefty System z credentials, has been pushing the idea of running large numbers of cheap virtualized x86 virtual systems on the zEnterprise for over a year, when DancingDinosaur covered the announcement of his STASH initiative then. Now he is working with Mantissa, known mainly as a provider of mainframe emulation products, on its latest product, z86VM, announced here.

Mantissa z86VM promises to simplify cloud deployment while dramatically reducing virtual image costs by potentially virtualizing thousands of x86 VMs on a zEC12 z/VM partition.  Porell actually isn’t ready to estimate how many until he has done more testing. At this point, all Mantissa is promising is a system that permits you to create virtual x86 machines for use as servers or desktop systems in minutes.

As Porell puts it: existing IBM zEnterprise server customers already have the capacity to run hundreds or thousands of virtual x86 machines. Now he invites DancingDinosaur readers (and anyone else) to try a free version of the z86VM beta software—to become a beta participant, send a request using this form and z86VM Beta as the subject. This will let you try out the latest version and see for yourself. The current beta ships with Small to Medium Enterprise (SME) Linux. SME Server is a CentOS Linux distribution specifically optimized and configured for use as web, file, email, and database servers. It employs a comprehensive browser UI for all management-related tasks.

Specifically Mantissa’s z86VM provides a 32-bit virtual x86 environment which cannot be distinguished by software from real x86 hardware. That means operating systems like Linux for x86 or Windows will run without alteration under IBM z/VM. An important aspect of this virtual operating environment is that no changes are required to move 32-bit x86 operating systems and applications to the z86VM environment. Current test projection modeling shows that up to 50,000 virtual images may be able to operate efficiently on a fully configured zEnterprise server.  But Porell is not quite ready to promise that.

Mantissa hopes to tie z86VM to cloud computing. “Cloud computing, server consolidation, virtual desktops, security, and resilience are all important considerations for customers of the zEnterprise server,” said Gary Dennis, co-Founder, Mantissa, in the beta announcement. “Most x86 virtualization deployments waste 25- 50% of all available hardware capacity.  The z86VM approach can’t do that because there is no real machine,” he add. Actually, there is a real machine underlying the system, currently the zEC12 or, presumably, any other zEnterprise.

Pricing for z86VM when it is released hasn’t been formalized. “My expectation is we will charge per engine, a la zLinux pricing. However, it may be more like z/VM or VMware pricing,” says Porell. The bigger difference is that there should be many more x86 images per core than you’d see with a conventional x86 system. Since the z can run at 100% utilization without fear of failover, Porell expects to squeeze more systems onto each core, which will reduce application and operating system fees where pricing is based on actual cores.

Hybrid computing looms large in Porell and Mantissa’s hopes for z86VM.  For hybrid computing the z86VM can use the same software binary images as other platforms, Porell explains. It should speed the time to deploy those workloads as no new software versions need to be acquired or developed  while providing an ability to further reduce software license costs, environmental costs, operational expense, and complexity, he continues.

In addition, the z/VM hypervisor already is capable of running thousands of virtual system images in a single server. Most of the redundancy necessary for business resilience, fault isolation and disaster recovery is built into the z and the z/VM hypervisor. The z 86VM takes advantage of the z/VM hypervisor to provide the security functionality that isolates one virtual guest from another in such a way that bad behavior by one cannot compromise the execution or data associated with another.

At this point z86VM is looking mostly like a zEnterprise hybrid computing play.  Whether z86VM offers significant benefits beyond what you can do with a hybrid zEnterprise and z/VM will be seen what happens in the beta program, what other business compute needs they address, what they decide with pricing.

Also, hope you will register for Enterprise 2013 in Orlando, Oct 21-25. It will combine the System z and the Power Systems technical universities with an Executive Summit.  The session programs already are out for the System z and Power Systems tracks; registration has already started. Check it out here. DancingDinosaur will be there. In the coming weeks this blog will look more closely intriguing sessions.

Free Stuff Lowers Mainframe Costs

September 9, 2013

Timothy Sipples’ blog Mainframe recently ran a piece listing free software you can get for the System z. The piece, here, is pretty exhaustive, including direct links. In keeping with DancingDinosaur’s continuing search for ways to lower mainframe computing costs, listed below some of Sipples’ freebies; find more in his full piece.

While freebies are always welcome, another proven way to lower mainframe costs is by paying close attention to mainframe software usage and costs. For this, BMC introduced a mainframe software cost analyzer tool that promises to reduce mainframe software operating costs by 20%. Called the BMC Cost Analyzer for zEnterprise, it aims to help IT departments plan, report and reduce their mainframe licensing charge (MLC) by identifying system peaks and recommending preemptive cost-reduction strategies. After deploying the BMC Cost Analyzer, a typical customer consuming 5,000 MIPS — at an annual cost of $3.6 million — could save $720,000 or more with the new BMC solution, according to the company.

Linux, an open source operating system licensed under the GNU Public License (GPL), is the first place Sipples looks for mainframe freebies. The GPL license means you don’t have to pay a license fee to obtain and use Linux; Linux distributors like Novell and Red Hat, however, do charge fees for their optional support services. Here are Sipples’ freebies for Linux on z:

Sipples’ list of IBM Freebies for z/OS, z/TPF, z/VSE, and z/VM

  • IBM makes its Java Software Development Kit (SDK) releases for z/OS available at no additional charge. You may also be interested in the Java technologies available from Dovetailed, such as Co:Z and Tomcat for z/OS.
  • The DB2 Accessories Suite for z/OS (5697-Q02) includes many useful tools and accessories to make DB2 for z/OS more powerful and more useful. Examples include IBM Data Studio, SPSS Modeler Server Scoring Adapter, Spatial Support, International Components for Unicode, and Text Search.
  • Go graphical! You can manage your z/OS system much more easily with graphical interfaces for every major subsystem and component. Grab the z/OS Management Facility. From the Explorer for z/OS you can then use (or directly install) plug-ins for CICS, IMS, IBM’s application development tools, IBM’s problem determination tools, and other products.
  • The XML Toolkit for z/OS (5655-J51) adds to the XML System Services that’s already part of z/OS.
  • IBM offers many more z/OS-related downloads including the IBM Encryption Facility for z/OS Client, Logrec Viewer, LookAt, z/OS UNIX System Service Tools and Toys, and many others.
  • Be sure to install the Alternate Library for REXX to run compiled REXX programs on your z/OS and z/VM systems. Compiled programs won’t run as efficiently as when the regular licensed REXX library is installed, but at least they’ll run.
  • The z/OS Ported Tools (5655-M23) include OpenSSH, IBM HTTP Server, and many other useful products. (Rocket Software also offers several ported tools.)

BMC conducts an annual survey of z data centers. This year, as in previous years, cost concerns were the number one issue.  The number two concern was business availability. The full survey will be released at the end of this month when DancingDinosaur expects to cover it in a little more detail.
