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 Technologywriter.com

 

 

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.

New zEnterprise Business Class Entry Model—zBC12

July 23, 2013

IBM introduced its new zEnterprise Business Class machine, the equivalent of the z114 for the zEC12, the zEnterprise BC12 (zBC12).  It offers significantly more power than its predecessor but the $75,000 base price hasn’t changed.

The company has been hinting at the arrival of this machine for months (and DancingDinosaur has been passing along those hints as quickly as they came). Of particular interest is that the System z Solution Edition pricing applies to the zBC12. Solution Edition pricing should make the machine quite competitive with x86-based systems, especially when running multiple Linux instances.

IBM isn’t being coy about its intentions to discount this machine. The initial announcement touted a new Linux-only based version of the zBC12, the Enterprise Linux Server (ELS). The ELS includes hardware, the z/VM Hypervisor, and three years of maintenance at a deeply discounted price. Besides over 3,000 Linux applications it includes two new capabilities, ELS for Analytics and Cloud-Ready for Linux on System z, each acting as an onramp for analytics or cloud computing.

DancingDinosaur has been a big fan of the Solution Edition program as the only way to get serious discounts on a mainframe. The big caveat is the constraints IBM puts on the use of the discounted machine. Each Solution Edition program is negotiated so just make sure you fully understand the constraints and all the fine print so you can live with it for several years. Of course, a zBC12 can be used for anything you would use a mainframe although enterprise Linux serving seems  an ideal use.

Besides its faster processor the zBC12 also offers up 156 capacity settings on each model  to choose just the right capacity setting for your needs along with a new pay-as-you-grow approach. When it is integrated with the IBM DB2 Analytics Accelerator, the zBC12 can perform business analytics workloads with10x better price performance and 14 percent lower total cost of acquisition than the closest competitor, according to IBM.

Out of the box the zBC12 specs look good:

  • 4.2 GHz processor designed to deliver up to a 36% performance increase per core to help boost software performance for business-critical workloads
  • Up to six general purpose processors designed to deliver up to 58% more capacity compared to the z114, which had five general purpose processors
  • Up to a 2x increase in available memory (496 GB) compared to the z114 for improved performance of memory-demanding workloads such as DB2, IBM WebSphere, and Linux on System z

The zBC12 comes in two models, the H06 and H13. Both are air cooled, single frame, or support 30 LPARS. The H06 has one processor drawer for 9 processor units. These can be divided between SAPs, CPs, IFLs/ICFs, zIIPs and zAAPs, and 1 IFP.  The Model H113 has two processor drawers to handle 18 processor units. It allows the same mix of processor types but in larger quantities and 2 dedicated spares. There are configurations where the H06 requires the second processor drawer. The entry processing level is 50 MIPS, up from 26 MIPS with the z114 with no change in the base price.

As far as other pricing, the zBC12 follows essentially an extension of the z114 stack pricing with a 27% price/performance improvement over the z114 for specialty engine pricing, which translates in 36% greater performance for the money.  Pricing for maintenance remains the same. Software keeps with the same pricing curve with a 5% discount applied. The price of Flash Express for the zBC12 remains at $125,000.

IBM has provided a straightforward upgrade path from the z10 or zEnterprise to the zBC12 as well as from the zBC12 to the zEC12. It also can be connected to the zBX (Model 003) to seamlessly manage workloads across a hybrid computing environment consisting of multiple architectures (Linux, AIX, and Intel/Windows).

The announcement of the zBC12 was accompanied by a slew of other new z announcements, including the new IBM zEnterprise Analytics System 9710,and native JSON support to bridge the gap between mobile devices and enterprise data and services along with conversion between JSON  and the new CICS Transaction Server Feature Pack for Mobile Extensions V1.0 and DB2 11 for z/OS (ESP).  Plus there is the new z/VM v6.3 and enhancements to the z/OS Management Facility.

As DancingDinosaur noted last week, expect z sales to get a boost in the next quarter or two as organizations choose the new zBC12. With its improved price/performance and low entry pricing and the Solution Edition deal for the zBC12 ELS the z should see a nice bounce.

New Ways to Lower System z Costs

April 26, 2013

The latest System z capacity offerings offer new ways to boost z usage at  lower cost. The offerings were developed jointly with z users in response to their specific business requirements.

The offerings, reflecting IBM’s willingness to be flexible on pricing, enable z users who typically handle operations like development and testing on cheaper x86 platforms to move those operations to the z while getting the additional capacity they would need at a lower cost. In the process, they eliminate the extra steps involved in deploying the finished production system on the z. You can find more info on IBM System z software here.

With the new capacity offerings and other initiatives, IBM is demonstrating its intention to drive down the cost of mainframe computing in a variety of ways. For example, with the System z capacity offering for Cloud, IBM offers the flexibility to increase capacity, then move portions of that incremental capacity within a 12-18 month period. This enables clients to grow before they know exactly where they’ll want to run the work, a welcome sign of flexibility. 

For System z disaster recovery in the cloud, again users gain more flexibility by moving workloads between systems.  For clients who are working aggressively towards business resiliency and disaster recovery, this can be very valuable and removes the restrictions previously out there on the number of tests than can be run.

Specifically, this allows active capacity mobility between zEnterprise primary servers and disaster recovery servers (mirrored data center) for more than just a one-time test.  IBM also offers comparable deals in the form of active multiplex pricing for GDPS Active/Active workloads.  While the DR offering requires all workload moves to the DR box at one time, the active multiplex offering allows fractional workload movement.

And finally, with the System z Test and Development offering, IBM is now allowing for discounts for clients who want do their testing on the platform. Previously, IBM was willing to lower the cost for development, but now, by doing development and test on the platform, it’s making the mainframe more attractive again.

None of this is exactly new. Last June DancingDinosaur reported that IBM was moving in this direction with its System z capacity offering for the cloud.  For more, click here.

IBM also announced new System z software for development, deployment and automation of workloads, described as simple-to-use tools for mainframe development. They start with a new enterprise COBOL compiler that promises significant performance improvements to meet increasingly narrow batch windows organizations face and a new Rational Developer for System z and Rational Developer for Enterprise.

Given increasing demands for new ways to connect the z to mobile activities, IBM also announced enhancements to CICS; specifically the CICS TS feature pack for mobile extension, the IBM Mobile messaging client, and Cognos Mobile on z/OS among others. Organizations have been connecting mobile applications to the z for years using SOA and gateways in one form or another.  These just provide another, possible more efficient way to do it.

After you build the app you need to deploy it. For this IBM announced a new Business Process Manager for z/OS, the Operational Decision Manager for z/OS, and Integration Bus on z/OS (previously called IBM WebSphere Message Broker for z/OS). Organizations also can rapidly deploy Java workloads with the new CICS Transaction Server for z/OS, Value Unit Edition. Finally, Tivoli System Automation on z/OS can provide automated end-to-end deployment and management.

At the same briefing IBM introduced Algar Telecom, a Brazilian telco that offers other services as well. A new z user, Algar consolidated large numbers of Intel servers on a z196 and zBX, an example of z-based hybrid computing.  It offers an interesting experience DancingDinosaur will take up in a later post here along with the experience of a z196 shop that upgraded to a zEC12 to create a z-based production systems core around a slew of Intel blades. Both organizations report good results.

Finally, please note: the IBM Edge Conference 2013 is coming up in Las Vegas, June 10-14. Last year Edge was primarily a storage event. This year there continues to be a large amount of storage material, including considerable new material around System z storage, but it appears IBM has expanded the program beyond storage. DancingDinosaur covered it last year and will begin covering Edge 2013 in a series of posts leading up to the event. Please join me in Las Vegas.  If you register here by 4/28 you can save a few bucks. Look for me there; I’ll be the blogger wearing the Mainframes Rule t-shirt.

New Announcements Fuel zEnterprise Rebound

February 6, 2013

A couple of weeks ago DancingDinosaur looked at the year-end results posted by IBM, with the z, led by the zEC12, leading the gains. Despite some tough quarters earlier in 2012, the System z has been on quite a roll; in 4Q12  it experienced 56% year to year revenue growth, the strongest since 2000.

The numbers look that much when better compared to what had immediately preceded them. In 3Q12, the z was down 19% on revenue (ouch).

The financials prove what long-time IBM watchers know: a new mainframe intro always kicks up the numbers, although it may take a quarter or two. The new machine, the zEC12, launched at the end of August 2012. Historically IBM follows a new mainframe with a business class version about a year after the initial launch, so we can expect a business class version of the zEC12 around August or September. (The z114 was introduced in July 2011, a year after the z196.) You can expect IBM will price it aggressively, as was the z114.

But it wasn’t only the new machine driving the good number.  Since the introduction of hybrid computing in 2010 with the zEnterprise 196, IBM has been doggedly pushing the idea of cloud computing, analytics (big data or otherwise), efficient centralized management, elastic scalability, and mobility. It has steadily brought out tools and optimizations that enhance the z for these kinds of workloads. Today its three main growth initiatives for the z focus on cloud, analytics, and security, which parallel IBM’s overall Smarter Computing thrust.

Optimizations and enhancements, like those announced or previewed earlier this week, will continue to drive the zEnterprise forward. For example, newly enhanced tools like z/OSMF (z/OS Management Facility) ease management of z/OS through a modern, browser-based console for z/OS.

The newest version, z/OSMF Version 2.1, previewed this week, provides intuitive management intended to enable IBM’s Smarter Computing through such capabilities as at-a-glance reports on software service levels and system software assets. New workflow capabilities promise to simplify z/OS configuration tasks and tune them to user roles. It leverages the Liberty profile for WebSphere for z/OS to accelerate deployment and speed time to value. Finally, it includes a REST API for jobs submission, which bridges batch and web-based applications and, in the process, helps bring younger z/OS system programmers up to speed.

Eletrobras Electronuclear, Brazil, the largest generator of electricity in Latin America, turned to z/OSMF for help in cloning its production system to ensure system resilience. As an Eletrobras manager noted: With z/OSMF this cloning process is much easier and can be completed in a matter of a few hours.

Also previewed was z/OS Version 2.1, described by IBM as the Smart Foundation for Smart Computing. z/OS v2.1 brings enhanced security through a new crypto server and support for additional industry security standards.  Enhancements around paging and throughput enable greater scalability while providing optimized performance reporting.  It offers enhanced data serving to fuel analytics for new data-hungry analytic applications as well as optimized data storage and faster file retrieval through an enhanced zFS along with improved FICON management. For management, it includes built in workload optimization, extended management reporting, and continued batch modernization.

IBM also previewed a z/VM upgrade, version 6.3. This adds support for 1TB of real memory and improved performance with HiperDispatch. The z/VM memory will provide better performance for larger virtual machines and reduced LPAR sprawl by allowing up to 4x more VMs per LPAR.  z/VM v6.3 boasts a higher server consolidation ratio with support for more virtual servers than any other platform in a single footprint, according to IBM.

Meanwhile IBM continues to roll out z customer examples at an increasing pace. Bankia, a Spanish banking company, turned to the System z for real-time integration of data to facilitate monitoring and mitigate risk. Vantiv, a leading payment processor based in Cincinnati, turned to the z for its cryptographic coprocessors to secure 2 billion transactions per month.

Marriott, an early zEC12 adopter, uses the machine to centralize its reservations and streamline the selling of rooms through elastic pricing. The University of Florida turned to the z for a scalable and reliable IT infrastructure that could accommodate students accessing and interacting with applications and data through mobile applications.

Already 2013 promises to be an interesting year for z shops. Expect more innovation, optimization, and a new low cost business class machine to accompany the zEC12.
