Variety of System Vendors at IBM Edge2015

May 7, 2015

An interesting set of vendor sponsors and exhibitors are lined up for IBM Edge2015 in Las Vegas next week. For the past weeks DancingDinosaur has focused on a small selection of program sessions.  Now let’s take a look at some of the vendors that will be there.

DancingDinosaur loves the vendors because they’re usually the ones underwriting the free entertainment, food, and drinks as well as giving out the nifty stuff. (My daughters used to love going off to school with what they considered cool multi-colored pens, Day-Glo bouncing balls, folding Frisbees, and more, which I picked up free at different vendors’ booths.)

Let’s start with Rocket Software. DancingDinosaur thinks of them mainly as a mainframe software provider with products for data management, performance optimization, catalog and system management, disaster recovery, storage management, and security. They also offer a bunch of interesting free utilities. At the end of April Rocket announced Rocket Discover, a self-service, intuitive data preparation and discovery solution to lets business managers and executives easily access, manipulate, prepare, and visualize data.

Both Brocade and Cisco will be there. In April, for instance, Brocade announced innovations for its campus LAN switch family. The switch is intended to help organization easily scale to meet increasing campus bandwidth demands. For instance it will deliver the industry’s highest 10 Gigabit Ethernet (GbE) port density for any switch in its class to accommodate what it refers to as the onslaught of user video and wireless traffic that is taxing campus networks.

In early May Cisco announced that Eletrobras, a Brazilian electric utility, would use Cisco’s technology for a smart metering initiative.  The project is expected to enable operational efficiency by improving service quality and control of non-technical losses, which, according to the company, reach 22% in the North and 10% in the Northeast of Brazil compared to required energy.

Of course Red Hat and SUSE, currently the leading Linux providers for the mainframe, will be there. DancingDinosaur has gotten some of his favorite baseball hats from each of these companies at previous IBM Edge conferences.

Red Hat introduced a new business resource planner as part of the latest releases of Red Hat JBoss BPM Suite and Red Hat JBoss BRMS. The planner, based on the open source OptaPlanner JBoss community project, is designed to help enterprises address complex scheduling and resource planning challenges. It also promises to increase operational adaptability in the face of rapidly changing and unpredictable business environments.

In late April SUSE announced the upcoming availability of SUSE Linux Enterprise Server for SAP Applications based on SUSE Linux Enterprise 12. New features, such as full operating system rollback, live kernel patching, and installation automation, should help simplify deployment and can increase uptime of mission-critical SAP solution-based workloads on Linux. SUSE customers should save time and resources as they experience improved performance and reliability.

Since the topic is Linux, let’s not forget Canonical’s Ubuntu, usually regarded as a desktop Linux distribution, is moving onto server platforms. At present Ubuntu is supported on POWER8 but not z. Ubuntu is included in numerous program sessions at Edge2015. For example, Ubuntu on Power – Using PowerKVM, presented by James Nash. The session covers various aspects to consider when moving to Ubuntu on the Power platform running in a PowerKVM environment.

In the exhibition area, where most people congregate for free food and drink after the program sessions there are over 30 exhibitors, including a handful of IBM units. For example, H&W Computer Systems  provides a handful of mainframe tools that enable you to run batch jobs during the business day without impacting CICS, automatically convert JES2 output to PDF or other formats, or use ISPF-like features to manage mainframe datasets. This is hardcore mainframe stuff.

An interesting exhibitor is ownCloud, an enterprise file sync and share system that is hosted in your data center, on your servers, using your storage. ownCloud provides Universal File Access through a single front-end to all of your disparate systems. Users can access company files on any device, anytime, from anywhere while IT can manage, control and audit file sharing activity to ensure security and compliance measures are met. (DancingDinosaur could actually use something like this—make note to check out this exhibitor.)

Recommend you spend a couple of late afternoons grazing through the exhibitor space, enjoying the food and drink, catching some demos, and collecting a new wardrobe of t-shirts and baseball caps.  And don’t forget to pick up some of the other funky stuff for your kids.

Of course, plan to save time for the free evening entertainment. In addition to Penn & Teller, a pair of magicians, and rocker Grace Potter, here. Also there will be a weird but terrific group, 2Cellos as well.

Linux on System z Update

August 27, 2012

It has taken a decade but Linux has finally firmly established itself in the mainframe world. As recently as 2Q 2012, IBM was reporting two-thirds of its top 100 customers had deployed IFLs, the assist processor for running Linux on the mainframe. Overall, one-third of its System z customers have deployed IFLs. Regardless of whether you are running Linux on the z today or not, Linux on z along with Java saved the mainframe from becoming just another niche technology instead of the versatile core enterprise platform it is today.

SUSE Linux Enterprise is the dominant version on Linux on the mainframe.  SUSE now is owned by Attachmate, which says it will runs it as an independent business unit to ensure it continues to focus on the benefits of open source.  SUSE has about 65% of the mainframe Linux market. Ubuntu and Fedora have negligible presence among mainframe Linux.

Red Hat Enterprise Linux (RHEL) holds most of the remainder on the mainframe Linux market.  Red Hat also offers Fedora, another Linux distribution intended primarily for individuals. After making steady inroads into SUSE’s mainframe Linux market share, progress appears to have slowed in recent months. At its annual Red Hat Summit last June the company celebrated crossing the $1 billion annual revenue threshold, a major achievement for any organization but especially for one built around an open source product.  The Red Hat event returns to Boston in 2013, June 11-14.

The Red Hat gathering  focused on the current hot IT issues—cloud, mobility, and cloud storage—but the mainframe was noticeably  absent. There has been some shifting of responsibilities among Red Hat personnel regarding the mainframe, but DancingDinosaur has been told it remains an active initiative. DancingDinosaur believes RHEL on the mainframe can certainly play an integral role in driving RHEL adoption throughout the enterprise, especially as it spreads through IBM’s various hybrid computing and cloud initiatives. And having two active Linux on z providers is good for mainframe computing.

This coming fall marks the first SUSECon event, something SUSE intends to make into an annual event. Planned for Orlando FL, Sept. 18-21, the event already is promoting Doug Balog, general manager, IBM System z, as a keynote. Balog is responsible for IBM’s worldwide System z server business. The conference promises to address enterprise Linux in the data center, cloud technology and infrastructure, and Linux systems management; basically what you’d expect.

In the meantime, SUSE released the second Service Pack for SUSE Linux Enterprise 11, which includes advanced exploitation of the latest IBM zEnterprise hardware, improved systems management, increased performance, and better problem analysis and resolution.  For example, new support for SSD makes it transparent to the DASD device driver, meaning no change required to use SSD

In terms of Linux functionality on the mainframe users see little differentiation between SUSE and RHEL from a product functionality standpoint. Makes sense since both are based on the Linux open source kernel. DancingDinosaur has profiled mainframe shops using each distribution. The choice often comes down to familiarity, services, and vendor attention to the customer. As hybrid computing gains traction among mainframe and Power shops and eventually PureSystems shops, however, the vendor—SUSE or Red Hat—that best addresses these new optimized multi-platform environments may gain an advantage.

For now, distinctions are minimal. A leading insurance company reports that it ended up using both distributions on its mainframe, starting first with Red Hat and then switching to SUSE and, a few years later, switching back to Red Hat.  As the project manager noted: “Either one works fine; you simply have to consider if your company already has a relationship with one of the vendors, your workload requirements, and any cost differences for code and support.” You also need to consider vendor readiness to support future initiatives like cloud, hybrid computing, mobile, and social business.

But changes are coming fast. IBM is inviting the industry to tomorrow’s virtual announcement of what it bills as the next generation zEnterprise system. Check it out.  DancingDinosaur will cover it in the next post.
