Storage is always an issue. Whether you’ve got petabytes of it on your mainframe or just 16GB on your smartphone or tablet, the issues are always the same. You want speedy access to the data you’re using, and you want somewhere to store the data you’re not using at the moment – but might want to use it later.
Speeding access to data can be helped in a number of ways – storing the data contiguously, using indexes to speed up access to individual fields, using shorter paths from the storage medium to the processor, keeping recently used data in cache storage in the likelihood it will be used again. Human ingenuity has come up with lots of workarounds to ensure that you get the data as quickly as possible.
But there’s more of an issue with archived data. I could have immediate access to it, but then it would cost as much to store as live data. I could store it on some cheap medium and find it takes a week to get it back to a state that I can use. And something along those lines is used by many archiving organizations. Those tapes are stored inside a mountain somewhere, and the data can be restored – but not quickly.
Depending on the kind of business you’re in, someone has made a decision about costs and storage retrieval speed. If your company is in banking or insurance, that data might get back much faster than if your organization doesn’t promise its customers fast access to old data.
The advent of cloud computing added another layer of complexity to storage. You could store your data on the cloud – which, in psychology terms, is called a nominalization. You call it something, which seems to have meaning, but isn’t a concrete real thing – you can’t put it in a wheel barrow. You hear politicians use nominalizations all the time. I’ll vote for prosperity and world peace – but what does that actually mean? Prosperity for someone from a third world country might seem quite close to poverty to me! And world peace can always be achieved by having a tank on everyone’s lawn. Your idea of what is meant by a nominalization may be completely different from the idea held by the next person!
Anyway, I digress. So nowadays, you can store your data on the cloud. You don’t know where it’s physically stored you just know how to access it. And I assume much the same models are used for the price of cloud storage – fast access is dearer than slow access. Amazon came up with, what they call, Amazon Glacier. This is a cheap service for archived or backed up data that you don’t access very often. In line with that pricing model, retrieval can take several hours. Amazon Glacier only charges organizations for the storage space they use.
I’ve been using a Pogoplug for over two years and I’ve mentioned it in this blog a few times. A Pogoplug started life as a small device that plugged into your router and allowed you to plug in memory sticks that you could access from a browser anywhere. The company has recently expanded its cloud offerings and has done a deal with Amazon to offer cloud storage at a very competitive rate. The solution isn’t for mainframers, but makes sense for individuals and small companies.
The Pogoplug Web site at http://pogoplug.com gives all the price plans they’re offering. So, a small organization would be able to back up files from their computers, smartphones, and tablets to one secure location. All the company has to do is buy a Pogoplug device or download the Pogoplug Server software and run it on a Windows or Mac. They can then back-up and archive their files – and we’re talking terabytes of space. Users can continuously copy all or part of their data to Pogoplug’s secure offsite cloud. Any changes they make to their original folder will be synchronized automatically.
It seems like a useful addition to the all-important back-up and restore choices a company has to make.

Where do the tablets go?
So, your organization has a mainframe – had one for years – and everything is nicely locked down. You can recover almost up to the minute the system or subsystem crashed (which it hardly ever does), and you’ve got people who seem to know, almost by instinct these days, when something isn’t performing quite right.
On top of that, you’ve got another layer of IT. People who use laptops with Windows and/or people who use Linux, and possibly bits or Solaris dotted around. These people have more interesting lives. They have to fight to get the best performance. Their back-up strategy is good if they can recover to last night! They probably still insist on people using XP as their Windows operating system because Vista was no good and it’s a bit of a jump to Windows 7. Plus they’re probably coming to the end of a virtualization project to reduce the number of server boxes they’ve got lying around. Parhaps they’re installing Citrix to virtualize desktops, or SharePoint to produce an intranet and join up all the separate islands of computing.
Plus you’ve got remote users, who are logging in over somebody else’s wifi. Or they might be using the 3G network on their smartphone. It’s your fault, of course, because you spent so long changing your CICS and IMS applications so they could be used in a Service-Oriented Architecture (SOA) environment. But, I guess you have strategies in place to secure the connection, and secure what applications they can run, and what data they can see.
In fact, you’re probably convincing senior managers in your organization that it really was their idea all along to combine the strengths of mainframe computing with the flexibility of distributed systems. What your organization needs is a nice z196 mainframe – perhaps one of the planned-but-not-quite-announced Business Class (BC) machines.
For those of you who’ve spent the past year on Mars, the z196 brings together the latest mainframe technology with POWER7 and x86 IBM blade systems, giving potential users z/OS, AIX, Linux, and (coming soon) Windows, all on the one box. At this stage, I should point out that there are very strong arguments for going to zLinux. It’s been around for 10 years now, and is just becoming an overnight success – as they say.
So, there you are thinking that you can use your mainframe experience and expertise to tidy up all the other computing areas in your organization and get them under your control when HR tells you they have supplied everyone on the board of directors with an iPad. Now, you might think this is a good opportunity to bring some of the board into the 21st century, but it creates yet another rip in the secure blanket you've been throwing over the company’s computing infrastructure. Can you set up a security policy for iPads? Well, yes, if they come into a Microsoft server – in the same way you would for Mac users. Can you allow board members to download apps? Or can they have only pre-approved ones? Where do you start building proper security? It’s back to herding cats!
And don’t think I’ve singled out iPads, Androids have similar issues. You can download firewalls and anti-virus software for them, but it’s not the same as RACF!
And it might not just be board members – you may still have road warriors that want the small form factor of a tablet. The issues of theft or forgetfulness compound your security problems.
My suggestion at this stage is to wait for Windows 8 tablets, and hope that the policies laid down by the non-mainframe ITers will apply to them. And by then, Windows will be running on our z196 box. So everyone’s a winner!

Cloudy but good
All this talk about 2011 being the year of the cloud rings true. I say that because marketing hype is usually a bit ahead of the curve. But I realize that I’m using cloud computing a lot these days – and I don’t mean (necessarily) for work.
Firstly, I’m using Google Cloud Connect for Microsoft Office. This is a small piece of code that’s free to download from http://tools.google.com/dlpage/cloudconnect. Once installed, you can save all your Word etc files on your laptop AND there’s a copy in Google Docs. Now, the reason I find that so useful is not simply because I know my documents are backed up (and to be honest that’s a really important reason and the one that I’d use as a selling point to most people), but it also means that I can access the documents from other computers. I have two laptops that I use all the time, and a third one, that’s usually away at users’ sites. I can now access my documents wherever I am and not have to say that I’ll send on the information after the meeting (or whatever).
Google also say on their site that this system allows users to simultaneously edit their files – which again is a great idea, although it’s not something I’ve tried.
Previously to using Google Cloud Connect, I used my Pogoplug for the same reason. I’ve mentioned Pogoplugs before in these blogs because they are so useful. It provides my own personal cloud. A Pogoplug is a little piece of kit that connects to your router. I then have four or five memory sticks plugged into it, but I could have a 2TB external hard drive. I can upload files to the Pogoplug from anywhere using a simple browser interface (https://my.pogoplug.com/) and I can share files with people, so they can see photos I’ve taken or short videos, or even Office documents. And, again, it provides me with a back-up copy of my important files.
The third piece of cloud computing I use is Wyse PocketCloud. I’ve downloaded the free app for my Android smartphone and I’ve downloaded the software for my laptop. Once they’re password synchronized, I can control my laptop from my phone. Which means, if I haven’t got a document with me, I can use my phone to launch Word on my PC and read the document. Last week I sent a document from someone else’s computer to my e-mail address. I used the PocketCloud software to log-on to my e-mail, download the file and print it. So when I returned back to base, there was the document ready for me to take to the next meeting (a school governors meeting – they don’t have wifi, hence I couldn’t be paperless). I’ve sat in McDonalds and called up files! It is a really impressive piece of software. Now, with the other cloud facilities mentioned above, I don’t know how much I’ll need to use it. But it just seems so amazing to be able to do it!
What I’m suggesting is that cloud computing is getting in under the radar and people are beginning to use it already. So, when IT departments suggest rolling out Cloud services in whatever form that takes for them, they will be pushing at an open door. There won’t be usual user resistance because the users will be perfectly happy with the concept. And, of course, mainframers will be saying that they’ve been using these cloud concepts since the 1960s – or whenever they first started working with mainframes.
Which all goes to show that 2011 really is the year of the cloud.

Johnny head-in-the-clouds
Almost everyone is predicting 2011 will be the year when cloud computing becomes a reality for many organizations. CA produced surveys towards the end of last year showing this to be part of the planning of most of the organizations they surveyed. Other surveys, like BMC’s and the Arcati Mainframe Yearbook found that cloud computing wasn’t quite on the radar of many of the people who actually do the day-to-day systems work.
This week has seen a report from IBM suggesting that 70 percent of small and medium businesses – perhaps not its usual massive mainframe users – are either planning to, or already do, deploy cloud-based IT infrastructures to improve their performance and reduce costs. For the report, IBM surveyed 2,112 business and information technology decision makers at midsize businesses around the world, and the publication is called Inside the Midmarket: A 2011 Perspective.
Also in the report was a finding that these same SMBs were moving from cost control to growth in terms of cloud computing. The report says that 62 percent of surveyed organizations are planning to increase their IT budgets in the next year or so. Now one spin on that would be that the world is out of recession and all’s good with the world. An alternative way of looking at it is to say that most sites have reduced or kept spending the same for the past two years and there’s a huge amount of pressure – like a boiling kettle – to update hardware and software.
The survey also found that 70 percent of respondents are actively pursuing business analytics to help give them some kind of insights into the huge amounts of data they’ve generated. The survey also found that 66 percent of respondents say they are embracing the benefits of cloud computing to optimize costs and redundancy while increasing uptime and scalability.
Obviously cloud computing is new to so many of the organizations surveyed and perhaps not surprisingly it was found that more than 70 percent are looking for local business partners with industry expertise for more of a consultative – rather than a purely transactional – relationship.
In other news (as they say) the new CEO at HP, Leo Apotheker is looking to make his company a leader in the development of infrastructure and platform Cloud services with an open Cloud, which many people assume will compete directly with Google's similar Cloud-based offering.
My final words of ‘wisdom’ on this matter is that we all think we know what we mean by cloud, but for many organizations it might be like shopping for a ‘car’ or ‘automobile’. You could end up with a Rolls Royce or second-hand Reliant Robin! As you work your way down into the nitty gritty details of what your organization needs, you can find cloud computing to be a fairly nebulous term!

Arcati Mainframe Yearbook 2011 user survey
The Arcati Mainframe Yearbook 2011 has been available for download free from www.arcati.com/newyearbook11 for nearly a month now. 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 100 respondents who completed the survey on the Arcati site did so between 1 November and 3 December 2010. 32% were from Europe and 52% from North America, with 16% from the rest of the world.
44% of the respondents worked in companies with upwards of 10,000 employees worldwide, while 14% of respondents had 0-200 staff, 10% had 201-1000, 14% had 1001 to 5000, and 14% had 5001-10,000 staff. In terms of MIPS, 50% of respondents had fewer than 1000 MIPS installed, 24% fell into the mid-sized category between 1000 and 10,000 MIPS, and 22% were at the high end.
Looking at MIPS growth produced some interesting results. Larger, more mature businesses (above 10,000 MIPS) were almost all experiencing some growth, but predominantly in 0 to 10% per year category. Sites in the 1000-10,000 MIPS range were showing a range of results with some sites suggesting a decline while others predicted growth in excess of 50%. Sites below 1000 MIPS were most likely to be experiencing growth of less than 10%, with the largest percentage (of these three groups) predicting a decline. The mainframe market does appear to be quite fragmented with competitive pressures at the lower end of the mainframe market, and some respondents commented about lack of understanding amongst management about the value of mainframe computing.
With the environment and environmental issues getting so much coverage in the media these days, the survey asked whether IBM’s recent green initiatives on things like power consumption and cooling had made the mainframe more or less attractive. Nearly three-quarters (72% – the same as the previous year) said that IBM’s green initiatives made no difference at all. 17% felt it made the mainframe a little more attractive, and 11% felt it made the mainframe a lot more attractive. Clearly “greenness” isn’t much of a selling point for mainframes.
With so much talk about Cloud Computing, for the first time the survey asked the mainframe population for their opinion. It asked whether respondents currently used their mainframe for cloud computing. Only 2% of respondents said they did. 34% said they didn’t, and the rest weren’t sure. Bearing in mind that it is still early days for a cloud computing initiative, the survey asked whether respondents were planning to adopt cloud computing as a strategy. 22% said they weren’t at present. 8% thought some mainframe applications would be cloud-enabled in the future, and a similar number thought most would be cloud-enabled in the future. However, 4% didn’t see a use for cloud computing. It will be interesting to follow these figures in future surveys.
The survey asked respondents which specialty processors (IFL, zIIP, and zAAP) they had. 6% of sites had all three (down from last year’s value of 12%) and a further 28% of sites had two of the three specialty processors (up from last year’s 12%). More sites had zIIP processors (44%) than any other. 36% had IFL processors, and 24% had zAAP specialty processors. 36% of sites don’t have a specialty processor installed.
It seems that at many sites, mainframes are losing out due to management ignorance. The survey quotes one respondent who said: “We do not expect to have a mainframe within 2-3 years. The CIO sees the mainframe as obsolete and expensive, whether or not either of those is true”. Another respondent complained: “Our architects do not understand mainframes and seem to be mostly knowledgeable about Windows. Project funding is project based and not enterprise based, hence a tendency to prefer perceived cheaper solutions, eg Windows.”
The appearance of the z196 processor had a big impact within the industry. High-profile TV appearances of Watson on Jeopardy keep people familiar with the name IBM. However, there is still a lack of understanding of what a mainframe does and what it can do amongst far too many IT managers and other corporate executives.
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 to mainframers because of the support given by sponsors. This year’s sponsors were CA Technologies, Canam Software, DataKinetics, and Type80 Security Software.

Mainframe computing 2011
This is the time of year when people make predictions for what we can expect to see in the coming year, so here are my predictions...
I predict that the Arcati Mainframe Yearbook will appear in early January and be downloaded by around 15 000 mainframe professionals. The Yearbook includes an annual mainframe user survey, an up-to-date directory of vendors and consultants, a media guide, a strategy section with papers on mainframe trends and directions, a glossary of terminology, and a technical specification section.
I also predict the Virtual IMS user group will restart its virtual meetings and newsletters early in the New Year. Virtual IMS is a user group established as a way for individuals using IBM's IMS hierarchical database and transaction processing systems to exchange information, learn new techniques, and advance their skills with the product. The first virtual meeting takes place on Tuesday 8 February at 10:30 CDT. The presentation is by Fundi Software’s Jim Martin and is entitled, “Solving the problem when IMS isn't the cause”. Users might report slow response time from IMS, but you suspect that other systems are responsible. For example, what appears to be an IMS performance problem could be a CICS, DB2, WebSphere, or z/OS performance problem. Your challenge is to correlate performance data in IMS with activity in these other systems in order to discover the cause of the slow response time. This talk will explain how to do it.
With all the hype about cloud computing, 2011 is the year cloud computing will become commonplace. In many ways, this is a major technology change that is being driven by users. They like the simple life (or should I say, we like the simple life). It’s very easy to turn on your browser and have all the applications you want just there waiting for you – like the apps on your phone. You then use the applications as you want them. Users are looking for the same simplicity in their working environment and organizations are going to have to provide this paradigm-shift way of working.
And talking of smart phones, I predict that the device of choice is not going to be a small laptop or netbook, but a large smart phone (or small tablet). Something that you can fit in your pocket, but has everything you need to do a day’s work on it. And, of course, cloud computing makes this easier too.
I predict there will be more GUI-looking software on mainframes so that youngsters will feel right at home using the technology. And I predict there will be much more mainframe automation going on – which will allow the few experts available within an organization to do more work with fewer resources.
Social media will have embraced all sizes of businesses, so if you want to find out what IBM or any other major (or less major!) vendor is up to, you’ll be able to do it in the Twitter, Facebook, whatever, environment you are currently familiar with.
In the consumer market, I predict more people watching TV programmes through laptops and smart phones. It’s so easy and convenient to catch the latest news on a smart phone.
I predict that mainframes will NOT disappear in 2011.
I predict the arrival of more mainframe monitoring apps on smart phones – so you know straightaway if there is an issue with the network etc. You’ll then pull out your tablet or laptop and solve the problem using the nice GUI on the software.
I’d also like to predict world peace and harmony – maybe next year!
I also predict the Virtual IMS user group will restart its virtual meetings and newsletters early in the New Year. Virtual IMS is a user group established as a way for individuals using IBM's IMS hierarchical database and transaction processing systems to exchange information, learn new techniques, and advance their skills with the product.

I’d also like to predict world peace and harmony – maybe next year!

2010 mainframe review
As this will probably be my last blog of 2010, I thought it would be traditional to review what’s happened in the mainframe world over the past year.
2010 will probably be remembered as the year of the cloud because it was the year when cloud computing started to be taken seriously across the industry. Microsoft opened its ‘mega data centre’ in Dublin and promoted its Windows Azure environment for development, service hosting, and service management based on the cloud. Google worked with VMware to develop a new operating system for the cloud, and launched a version of the Google App Engine for enterprise users. Amazon promoted its Elastic Compute Cloud (Amazon EC2) service. And many people suggested that mainframes have offered cloud computing all along – we just called it something else!
IBM’s acquisitions this year include: National Interest Security Company, Initiate Systems, Intelliden, Cast Iron Systems, Sterling Commerce, Coremetrics, BigFix, Storwize, Datacap, Unica, OpenPages, Netezza , PSS Systems, and Clarity Systems.
The big story of 2010, of course, was the launch of a new mainframe range in July. The zEnterprise 196 brings together the latest mainframe technology with POWER7 and x86 IBM blade systems, giving potential users z/OS, AIX, and Linux all on the one box. And all this is controlled from the mainframe console by the new Unified Resource Manager. This new mainframe can be thought of as a virtualization hub that manages other workloads in the data centre.
For people who like to stay current with the latest version numbers and dates of major products, CICS 2.1 has been available since the middle of 2009, DB2 10 was announced earlier this year, as was z/OS 1.12, and IMS 12 should be generally available early in the New Year.
The battle between IBM and NEON Enterprise Software (provider of the zPrime product, which allows users to run traditional workloads on specialty processors) has rumbled on in the courts for a year without any sign of an outcome. The European Union regulators have taken IBM to task for not allowing its operating system to run on other hardware, and for not being fair to so-called ‘spare-part’ vendors. The first complaint came from T3 and TurboHercules, saying that IBM ties its mainframe operating system to its mainframe hardware – and thereby destroys the emulation market.
For me and iTech-Ed Ltd it was a good year. I was given the accolade of IBM Information Champion again this year. My blog at Mainframe Update (mainframeupdate.blogspot.com) was again a finalist in the Computer Weekly annual blog awards. I was interviewed by CIPS (the Canadian Information technology Professionals). You can download a podcast of the interview from the CIPS Connections site at stephenibaraki.com/cips/v610/trevor_eddolls_2010.html. I was invited by CA to be on their expert panel for a webinar called “From Here to Eternity: The Mainframe as a Mainstay of the Enterprise” discussing cloud computing. Other panellists were Jon Toigo, CEO, Toigo Partners International; Keith Winnard, IT technical services, JD Williams; and Dayton Semerjian, general manager, mainframe, CA Technologies; and control of the session was maintained by Michael Krieger. iTech-Ed helped produce the Arcati Mainframe Yearbook 2010, which is still available for download from www.arcati.com/newyearbook10. The 2011 edition will be available in January. IBM Systems Magazine's Mainframe Extra eNewsletter was quite taken by one of my regular blogs and they included it in their "Links We Love" section. My articles on cloud computing and IMS was published in the October/November issue of zJournal. The links for the articles are www.mainframezone.com/it-management/ims-and-cloud-computing and www.mainframezone.com/it-management/sidebar-cloud-computing-origins-and-evolution. Exciting things are happening with the Virtual IMS user group that iTech-Ed runs. After a short hiatus, a new sponsor for the user group has been found and webinars and newsletters will continue for members and guests in the New Year. Look out for more details.

Making computing a recognized profession
Is there any reason to make computing a recognized profession? After all, isn’t it like gardening? Something we all do a bit, with varying degrees of competence for varying amounts of time in a week? Why should it be a recognized profession like medicine, law, or accounting? Does it really need demonstrable professional development, with members adhering to a code of ethics, and having globally recognized credentials?
I would argue that it does. Not only that, I would support whole-heartedly the professionalization of computing. Naming no names, but I’ve come across lots of IT personnel who have an incredibly limited knowledge of the choices available or the types of techniques that can be used to make things happen. I worked with someone many years ago who reckoned he could do anything on a computer with a few lines of code. He was a great hit with customers – they liked dealing with him. He wrote Assembler and he really did make things happen. So often these days, particularly with Windows support staff, the answer is always NO – a particular change can’t be made, either because it’s too much effort or because they don’t know enough.
On the other hand, there are things like ITIL – IT Infrastructure Library – which provide best-practice examples for service management. You can find them at www.itil-officialsite.com or www.itil.co.uk. And there’s IP3 (www.ipthree.org) who are all about setting standards for the IT industry.
I think organizations like this should be supported. I also think they should have some way of including in the membership recognized industry professionals who’ve been round the block a few times and should incorporate their skills and best practice.
At the moment, from a customer’s perspective, when you employ a consultant or an organization to work on your IT with you, you have no way of knowing how good they are or what standards they achieve compared to other similar organizations.
So, yes, I would absolutely support computing becoming a recognized profession – with continuous professional development, code of ethics, and, of course, letters after your name so customers know you adhere to these standards.

IBM launches London Analytics Solution Centre
I was invited to Southbank for IBM’s launch of its London-based Analytics Solution Centre – joining six other similar centres across the globe. The morning session included an introduction by Carolyn Taylor, and presentations by Brendan Riley (IBM’s head honcho in the UK), Lord Peter Mandelson (who spoke very well), and Cambridge University’s Professor Andy Neely. After a short Q&A we were shown some very interesting demos.
So what are these Analytics Solution Centres? We were told that the centres will help IBM apply its advanced analytics expertise to the complex business challenges facing its clients. You’re perhaps no clearer after I’ve just given the official answer. So let me try to explain in another way...
They were suggesting that there are lots of little bits of information floating around that could be tied together because this bigger picture would then help organizations make better decisions. An example we saw on video was of traffic flow. How it would theoretically be possible to measure the movement made by people’s mobile phones to measure the actual flow of traffic along busy streets. Using this information, faster alternative routing information could then be sent to, perhaps, the sat navs in the cars. That way, everyone would arrive at their destinations faster.
Another example that was demo’d was about flooding in Galway Bay. Previously, the local harbour master might have decided that a particular combination of rainy weather, winds, and high tides put the town at risk of flooding. Now, sensors in buoys are linked to other information to come up with a much better picture of when flooding might occur. It also links into other systems measuring water quality. And further system links local fish restaurants with local fisherman, who can say what fish they are catching, and the restaurant can put those fish on their menu for that evening!
We also saw the ORX (Operational Riskdata eXchange Association) system – which is used to help members quantify risk exposure. It was something banks needed following the Basel II accord. The banks’ risk information is securely and anonymously exchanged, and the banks are from 18 different countries. The consequence of this initiative is that banks now have a much better understanding of their exposure to potentially damaging operational risk.
Andy Neely stressed the need for getting the organization architecture right. He suggested that getting IT right saw an 8% improvement, and getting the organization right also saw an 8% improvement. However, getting them both right at the same time led to a 34% improvement!
The motto of the presentation, if I might call it that, was “predict and act”. The suggestion was that currently organizations tended to sense something was going on and then respond.
The Analytics Solution Centre in London will comprise around 400 consultants, software specialists, and mathematicians, and will include recent graduates. This number will increase as business increases.
Other Analytics Solution Centres can be found in Berlin, Beijing, Dallas, Tokyo, New York, and Washington DC.
The whole thing looks very exciting and an area destined to grow.
