What is Software Defined Anything?

If you’ve sat through a training seminar recently, you’ve probably seen a slide talking about software-defined anything or software-defined everything. Or you may have seen the acronym SDx and wondered what it is and where it’s come from. So let’s have a look at what they’re talking about.

Basically, what we’re looking at is using software to control different kinds of hardware, and then to make that software able to control multiple-component hardware systems. With the growth of the Internet of Things (IoT), it makes sense to start thinking about being able to create rules that are implemented in software that can be used to control a myriad of different types of devices.

At the moment there are a number areas using software-defined technology. For example there’s Software-Defined Storage (SDS), which seems to apply to all sorts of storage software, particularly virtualization software. Different vendors use the term loosely for different things. Software-Defined Networking (SDN) is where network devices are programmable and so networks themselves are more dynamic. Again, it’s a term that’s used by different vendors for different things.

Software-Defined Storage Networks (SDSN) is an attempt to virtualize storage networks by separating the actual physical network from its controlling software. A Software-Defined Hypervisor (SDH) seems to refer to virtualizing the hypervisor layer and separating it from its management console. And finally, there’s Software-Defined Infrastructure (SDI) aka Software-Defined Data Centre (SDDC), which is an aspirational concept where data centre services are controlled by policy-driven software.

Two things probably leap to mind about now. Firstly, this seems a lot like marketecture! We’ve seen this before, where vendors are really selling us an idea of something rather than it being a tangible reality. We are very much in the early days of this sort of thing. The second thing is that this is not directly linked to mainframes. This is VMware’s ideas – as well as a huge number of other companies.

Having said that, of course, the newer hybrid mainframes from IBM will be able to make use of this technology as it becomes available in reality. Also, Gartner reckons that SDx is one of the major disruptive technologies to watch. It makes it easier to scale up existing architecture and even try out different architectures. Also it makes it possible to tune networks, matching network performance to workloads. And, of course the main selling points are flexibility, agility, security, and price.

IBM’s Smarter Computing blog has an interesting blog by Shamin Hossain called “Software defined everything: When a data center becomes soft”, which can be found at http://www.smartercomputingblog.com/software-defined-environment-2/software-defined-everything/.

Clearly the prefix ‘software-defined’ is one that we’re going to hear a lot more about this year.

The Arcati Mainframe Yearbook - user survey findings

The Arcati Mainframe Yearbook 2014 is now available for download from http://www.arcati.com/newyearbook14 – and it’s FREE. Each new Yearbook is always greeted with enthusiasm by mainframers everywhere because it is such a unique source of information. And each year, many people find the results of the user survey especially interesting.

The results came from the 100 respondents who completed the survey on the Arcati Web site between 1 November and 6 December 2013. 51% were from North America, 33% were from Europe with the remainder from the rest of the world.

Half of the respondents worked in companies with upwards of 10,000 employees worldwide. Below that, with 24 percent of respondents, were staff sizes of 1001-5000, 10 percent with staff sizes of 0-200, nine percent with staff sizes of 201 to 1000, and only seven percent with staff sizes of 5001 to 10,000. In terms of MIPS, 28 percent had 1000-10,000 MIPS, down again from last year’s figure of 36 percent. 16 percent had under 500 MIPS, only 15 percent had 500-1000 MIPS, 13 percent had 10,000 to 25,000 MIPS, and 17 percent had over 25,000 MIPS installed.

Looking at MIPS growth produced some interesting results. 71 percent of sites of mainframe installations are experiencing some growth, with three sites claiming growth in the region of 26-50 percent. Only eight percent of sites are reporting a decline in mainframe capacity growth. 11 percent of sites are not expecting any kind of change in their MIPS this year. Small sites (32 percent) are most likely to have seen some kind of decline or to have stayed the same, and yet, in complete contrast, they were more likely to see growth in the 26-50 percent range. While some larger sites (above 10,000 MIPS) did report a decline or no growth, the majority were anticipating some kind of growth possibly up to 50 percent per year. Mid-range respondents were typically expecting some kind of growth (89 percent of sites). It is a confusing picture with nearly a third of small sites, 10 percent of medium sites, and 17 percent of larger sites showing no growth or a decline. Perhaps sites have been holding off on growth until the global economic climate brightens up.

The survey looked at whether sites currently used their mainframe for cloud computing. Only seven percent of respondents said they did. The survey also asked whether respondents were planning to adopt cloud computing as a strategy. 50 percent said they weren’t at present. 16 percent thought some mainframe applications would be cloud enabled in the future. And 15 percent  claimed that some of their applications are using the cloud model.

There’s been a huge growth in the use of social media in recent years, and the survey wondered whether those people “using their dad’s technology” found social media (Facebook, Twitter, Youtube, etc) useful for their work on the mainframe. 18 percent said that they did, with 13 percent not sure, and the rest not using it at all. With IBM having Facebook pages dedicated to IMS, CICS, and DB2, it seems a shame if they’re not being used.

With the growth in number of software products that allow users to monitor the mainframe from a browser on a tablet/iPad or smartphone, the survey looked at whether mainframers were using these devices to monitor or control their mainframe. Only nine percent said that they were.

Another hot topic through 2013 has been Big Data and all the things associated with that (such as Hadoop). The survey asked whether sites had any plans to use Big Data. Just two percent of sites said that they were already using Big Data, with a further 12 percent planning to do so.

The survey also asked about BYOD (Bring Your Own Device). It wanted to know how important sites thought it was to make mainframe data available to other platforms. 78 percent of sites said that it was very important to the way they work at the moment. Three percent are in the planning stage, and nine percent expect to do some work on this in the future. When it comes to how important is the idea of people using their own devices (BYOD) to access mainframes, 15 percent of sites said it was very important to the way they work now – but 47 percent said it wasn’t important.

Anyway, full details of the responses to many other questions can be found in the user survey section of the Yearbook. It’s well worth a read.

The Yearbook can only be free because some organizations have been prepared to sponsor it or advertise in it. This year’s sponsors were: Software Diversified Services (SDS), Software AG, zIT Consulting, and CA Technologies.

The Arcati Mainframe Yearbook 2014 has been published

Every year, about this time, mainframe users are excited to get their hands on the latest edition of the Arcati Mainframe Yearbook. What makes the Yearbook stand out is that it’s an excellent reference work for all IBM mainframe professionals – no matter how many years of experience they have.

What makes this annual publication so important? The answer is that it provides a one-stop shop for everything a mainframer needs to know. For example, the technical specification section includes model numbers, MIPS, and MSUs for zEnterprise processors (zEC12s, z196s, and z114s). There’s also a hardware timeline, and a display of mainframe operating system evolution.

In addition, there’s the glossary of terminology section explaining what all those acronyms stand for, in a way that means you can understand them. And this year we’ve added a number of Big Data terms that are becoming commonly used.

One section provides a media guide for IBM mainframers. This includes information on newsletters, magazines, user groups, blogs, and social networking information resources for the z/OS environment. Amongst the things it highlights are Enterprise Tech Journal, IBM Listservs, SHARE’s Five Minute Briefing on the Data Center, Facebook pages, and LinkedIn discussions; as well as user groups such as SHARE and IDUG.

The vendor directory section contains an up-to-date list of vendors, consultants, and service providers working in the z/OS environment. There’s a summary of the products they supply and contact information. As usual, there are a number of new organizations in the list this year – indicating that this is still an exciting market place to be in.

The mainframe strategy section contains articles by industry gurus and vendors on topics such as:

  • Research Report – Software Diversified Services’ E- Business Server: Encryption, Compression, Key Creation and Management?
  • The Challenge: Actively Control MLC Costs for IBM’s System z
  • Mainframe meets mobile
  • Your Business is Dynamic – Are You? Empowering the Dynamic Data Center.

For many people, the highlight each year is the mainframe user survey. This illustrates just what’s been happening at users’ sites. It’s a good way for mainframers to compare what they are planning to do with what other sites have done. I will be looking at some of the survey highlights in a future blog.


The other great thing about the Yearbook – as far as many of the 20,000 people who download it are concerned – is that it is completely FREE.

It can only be free because some organizations have been prepared to sponsor it or advertise in it. This year’s sponsors were: Software Diversified Services (SDS), Software AG, zIT Consulting, and CA Technologies.

Network management issues

I want to know what’s going on on my network – what do I do? Well this seemingly simple question has a complicated answer, which is historical and all to do with the separate worlds of the mainframes and everyone else coming together to give us our current complicated environment. Just to summarize, mainframes used SNA and VTAM to communicate and everyone else used TCP/IP. Sometime in the 1990s, all this came together. In addition, we now  have people on iPads and smartphones using our networks – in fact, we can have people on iPads and smartphones controlling our networks!

So, in terms of software, what are our choices for network management?

IBM has Tivoli OMEGAMON XE for mainframe networks, which allows you to monitor VTAM and TCP/IP networks and identify problems within those networks.

CA has its CA NetMaster Network Management for TCP IP and CA NetMaster Network Management for SNA products, which allow users to “proactively manage” their network. And there are a number of other more specialized products including CA NSM NetMaster Option, which lets you “manage your mainframe networks from CA Unicenter Network and Systems Management”.

SDS has Vital Signs for IP and Vital Signs for VTAM, which are both monitoring software.

William Data Systems has a whole range of products including ZEN OSA MONITOR for OSA performance monitoring and management, ZEN IP MONITOR (IMPLEX) for IP performance monitoring and management, ZEN EE MONITOR (FERRET) for APPN/HPR and EE monitoring and management, ZEN TRACE and SOLVE (EXIGENCE) for network problem determination, ZEN FTP CONTROL (FTPALERT) for audited FTP monitoring and management, ZEN EE SECURITY (APIAS) for secure EE deployment across any network, and ZEN AUTOMATION for automating network and operational tasks.

In fact, William Data Systems has just release Version 4.7 of ZEN TRACE and SOLVE, which includes more customer-suggested z/OS network tracing and solution capabilities to help busy z/OS network support people do more in less time – they claim.

If you are plagued by mainframe network issues, you may well be interested in the new features they’ve incorporated into ZEN TRACE and SOLVE V4.7, including:
  • The new “Peek” function, which provides in-flight viewing of active IP traces. This means that it is now possible to view an active trace while it is still running, tracking its progress ‘in-flight', and then stopping it when the condition being sought in the trace is detected. This can save considerable CPU costs and user time.
  • Traces originally captured in OSAENTA, libpcap, or Sniffer format can now be imported into ZTS. This can make network problem solving both faster and easier.
  • As well as being able to accept commands from the operator console, ZEN TRACE and SOLVE now adds the ability to issue any commands (including ZTS commands) from JCL. When combined with the capabilities provided by the new import features, this enables different trace formats to be automatically imported into ZTS for analysis. This greatly simplifies the whole network problem solving process.
  • Tracing of IPv6 is now faster and easier with the provision of improved Flow display text descriptions for recognizable packet contents, as well as the capability to search using IPv6 format addresses.
  • Tracing packets in large Sysplex environments is inherently complex, but ZEN TRACE and SOLVE v4.7 now makes it easier by providing improved facilities for expanding encapsulated data used by Sysplex protocols such as GRE and VIPA Route. Being able to view and expand encapsulated payload data is a vital tool for rapid problem diagnosis in large Enterprise networks.

If you’re finding network management is an issue, it might well be worth a look.
