Latest BMC Mainframe Survey Points to Bright System z Future

September 27, 2013

BMC Software released its 8th annual mainframe survey, and the results shouldn’t surprise any readers of DancingDinosaur. Get a copy of the results here. The company surveyed over 1000 managers and executives at mainframe shops around the world, mostly BMC customers.  Guess you shouldn’t be surprised at how remarkably traditional the respondents’ attitudes about the mainframe are.

For example, of the new areas identified by IBM as hot—mobile, cloud, big data, social business—cloud, big data, and mobile barely registered and social was nowhere to be seen.  Cloud was listed as one of the top four priorities by 19% of the respondents. Big data was listed as one of the top priorities for the coming year by only 18% of the respondents, the same as mobile.  The only topic that was less of a priority was outsourcing at 15%.

So what were the main priorities? The top four:

  • IT cost reduction—85% of respondents
  • Application availability—66%
  • Business/IT alignment—50%
  • Application modernization—50%

Where the researchers did drill down into one of the new areas of focus, big data, the biggest number of respondents, 31%, reported identifying the business use case as their biggest challenge. Other challenges were the cost of transforming/loading mainframe data to a centralized data warehouse (24%) followed by the effort such a transformation required (20%).  Another 11% noted the lack of ETL tools for business analytics.  Ten percent cited lack of knowledge about mainframe data content—huh? That might have been the one thing DancingDinosaur found truly surprising, although without knowing the specific job titles or job descriptions it might not be so surprising after all.

When it came to big data, 28% of the respondents expected to move mainframe data off the mainframe for analytics. An almost equal number (27%) expected the mainframe to act as the big data analytic engine.  Another 12% reported federating data to an off platform analytics engine. Three percent reported Linux on z for hosting the unstructured data.

Moving data off the mainframe for big data analytics can be a slow and costly strategy. One of the benefits of doing big data on the System z or the hybrid zEnterprise/zBX is taking advantage of the proximity of the data. Moving petabytes or even terabytes of data is not a trivial undertaking. For all the hype it’s clear that big data as a business strategy is still in its infancy with much left to be learned.  It will be interesting to see what this survey turns up a few years from now.

Otherwise, the survey results are very supportive to those who are fighting the seemingly perpetual battle of the mainframe as an end-of-life technology.  Almost all the respondents (93%) considered the mainframe a long-term business strategy while almost half (49%) felt the mainframe will continue to grow and attract new workloads.

Some other tidbits from the survey:

  • 70% of respondents said the mainframe will have a key role in Big Data plans.
  • 76% of large shops expect MIPS capacity to grow as they modernize and add applications to address business needs. (This highlights the need for software that minimizes expensive MIPS consumption and exploits the mainframe’s cost-efficient specialty engines.)

No large shops anyway—and only 7% of all respondents—have plans to eliminate their mainframe environment. Glad it’s not worse.

Lastly, there still is time to register for IBM’s Enterprise 2013 conference in Orlando. 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. Check out the System z overview here and the Power Systems overview here. DancingDinosaur will be there. In the coming weeks this blog will look more closely some intriguing sessions.

BMC Mainframe Survey Bolsters z-Hybird Computing

September 27, 2012

For the seventh year, BMC conducted a survey of mainframe shops worldwide. Find a copy of the study here and a video explaining it here. Most of the results probably won’t surprise you:

  • 90% of respondents consider the mainframe to be a long-term solution, and 50% expect it will attract new workloads.
  • Keeping IT costs down remains the top priority—not exactly shocking—as 69% report cost as a major focus, up from 60% from 2011.
  • 59% expect MIPS capacity to grow as they modernize and add applications to address expanding business needs.
  • More than 55% reported a need to integrate the mainframe into enterprise IT systems comprised of multiple mainframe and distributed platforms.

The last point especially suggests IBM is on the right track with hybrid computing. IBM also is on the right track in terms of keeping costs down, especially by enabling organizations to maximize the use of specialty engines in an effort to reduce consumption of costly GP MIPS.  The specialty engine advantage continues with the new zEC12, incorporating the same 20% price/performance boost, essentially more MIPS bang for the buck.

Two-thirds of the respondents were using at least one specialty engine. Of all respondents, 16% were using five or more engines, a few using dozens.  Not only do specialty engines deliver cheaper MIPS but they often are not considered in calculating software licensing charges, which lowers the cost even more.

About the only change noticeable in responses year-to-year is the jump in the respondent ranking of IT priorities. This year Business/IT alignment jumped from 7th to 4th in priority ranking. Priorities 1, 2, and 3 (Cost Reduction, Disaster Recovery, and Application Modernization respectively) remained the same.  Priorities 5 and 6 (Efficient Use of MIPS and Reduced Impact of Outages respectively) fell from a tie for 4th last year.

The greater emphasis on Business/IT alignment isn’t exactly new. Industry gurus have been harping on it for years.  Greater alignment between business and IT also suggests a strong need for hybrid computing, where varied business workloads can be mixed yet still be treated as a single system from the standpoint of efficiency management and operations. It also suggests IT needs to pay attention to business services management.

Despite the mainframe’s reputation for rock solid availability and reliability, the survey also noted that 39% of respondents reported unplanned outages. The primary causes for the outages were hardware failure (cited by 31% of respondents), system software failure (30%), in-house app failure (28%), and failed change process (22%). Of the respondents reporting outages, only 10% noted that the outage had significant impact. This was a new survey question this year so there is no comparison to previous years.

Respondents (59%) expect MIPS usage to continue to grow. Of that growth, 31% attribute it to increases in legacy and new apps while 9% attributed it to new apps. Legacy apps were cited by 19% of respondents.

In terms of modernizing apps, 46% of respondents planned to extend legacy code through SOA and web services while 43% wanted to increase the flexibility and agility of core apps.  Thirty-four percent of respondents hoped to reduce legacy app support costs through modernization.

Maybe the most interesting data point came where 60% of the respondents agreed that the mainframe needed to be a good IT citizen supporting varied workloads across the enterprise. That’s really what zEnterprise hybrid computing is about.
