Guide Share Europe annual conference

The Guide Share Europe (GSE) UK Annual Conference is taking place on 13-14 November at Whittlebury Hall, Whittlebury, Near Towcester, Northamptonshire NN12 8QH, UK.

Sponsors this year include IBM, Computacenter, PKWARE, CA Technologies, Attachmate Suse, Vanguard, Compuware, GT Software, RSM Partners, Blenheim Software, Sett, and Red Hat. And there will be over 30 vendors in the associated exhibition.

There’s the usual amazing range of streams – and, to be honest, there are a number of occasions when I would like to be in two or more places at once over the two days. The streams are: CICS, IMS, DB2, Enterprise Security, Large Systems Working Group, Network Management Working Group, zLinux, Storage Management, TWS (Tivoli Workload Schedular), Automation, New Technologies, Software Asset Management, MQ, Application Development, and Assembler Training.

There are also keynotes from Mark Anzani, VP and CTO for System z at IBM. And there’s the not-to-be-missed “Dealing with difficult people” session from Resli Costabell.

That means that at this year’s conference there will be well over 140 hours of education covering most aspects of mainframe technology – more than last year. This year, there will be 14 streams of ten sessions over the two days, plus Assembler Training, plus four keynotes.

There is still time to register, and the organizers are expecting the daily total of delegates to exceed 300 – as it did last year.

A number of the streams have 101 sessions at different times during the two days to give newcomers and those unfamiliar with parts of the mainframe infrastructure a basic understanding of the that mainframe technology and how it works.

You can find out more details about the conference at www.gse.org.uk/tyc/.

If you’re still debating whether to go, let me recommend it to you. The quality of presentations is always excellent. And the networking opportunities are brilliant. If you are going, I look forward to seeing you there.

Cloud initiatives from IBM

2011 has been dubbed by some as the year of the cloud – the year when cloud computing comes off the PowerPoint slides and onto a computer near you. Others have muttered wisely about similarities with client-server computing, which for many years was the ‘technology of the future’ at every presentation and never quite arrived the way we were promised.

Anyway, this week saw announcements from IBM about cloud computing. It announced Tivoli Provisioning Manager 7.2, which creates virtual server images in minutes and automates the management of virtual environments and hybrid cloud systems. The software is also claimed to help to better protect data in the cloud. And the software provides ‘image management’ of a virtual environment, which means that as computing needs change the number of virtual machines can be scaled up and down.

Provisioning Manager works stand-alone or with other Tivoli management products. It works across Power-based servers and Intel x86 instruction set-based servers. It can manage LPARs (logical partitions) or WPARs (workload partitions) on AIX servers. It also manages virtual machine images provided by VMware ESX Server, Citrix Systems XenServer, and Red Hat’s open source KVM (but not Microsoft’s Hyper-V, yet) on x86 servers.

The beta availability of new hybrid cloud management capabilities were announced by IBM at the PULSE 2011 conference. Tivoli Provisioning Manager and other components can manage virtual machines across an internal enterprise cloud and an external public cloud. However, this doesn’t extend to other public clouds, yet.

Tivoli Storage Manager for Virtual Environments (also in beta) utilizes VMware’s vStorage APIs for Data Protection. By doing so, it offloads the back-up function from the virtual machine and ESX Server host to a VMware vStorage back-up server. Storage Manager is then able to request more frequent back-ups, ensuring greater data protection without placing excessive demand on virtualized system resources. It also allows smaller and faster back-ups that replicate only data blocks that have changed since the previous back-up by making use of VMware’s Changed Block Tracking.

The same week saw a discussion about cloud computing at the CeBIT expo in Hannover in Germany. There it was suggested that the adoption of cloud computing was being held back by issues such as security and reliability. One solution to the security issue was to use private clouds or shared private clouds. Another challenge that was highlighted was bandwidth (or the lack of it). They focused on the amount of data that would need to be moved around in a cloud environment might be too much for the existing infrastructure. The fourth issue the conference identified was interoperability – and the need for standards was highlighted. My personal opinion is that too often computing (and technology in general) has been held back by standards – the very fact that there are far too many of them! Have you ever tried to use someone else’s phone charger to charge your phone, only to find it has a completely different connector (let alone different amps and volts, etc). But you remember SOA and the plethora of standards, etc – OK rant over.

I’m sure this blog will return to cloud announcements, developments, and set-backs many times during this year!

Linux on mainframes – 10 years old already

It seems so long ago, back in 1999, when we were discussing the Y2K bug (that was going to bring the universe as we knew it to an end) and whether Linux on a laptop was ever going to scale to mainframe proportions. And, while at the time I said the Y2K bug was overhyped (but then we all said we said that afterwards!!), I was never overly sold on mainframe Linux – wondering what kind of strange hybrid creature it would be. Doh! Not only has mainframe Linux (Linux on System z) now celebrated 10 years of service, it is a hugely successful and growing part of the mainframe world.

In 1999 IBM announced its commitment to Linux and promised to make it available on all their platforms and also produce Linux versions of its software. This meant that IBM would be spending lots of money on Linux and needed it to be a success. I can remember talking to various people at conferences, and the general opinion was one of confusion. IBM sold operating systems, so why would it champion a free alternative? If Linux didn’t become a success then IBM would have wasted lots of money – which could have been spent improving its other products. Alternatively, if Linux did become a success, pundits wondered whether that would result in a drop in IBM’s software and hardware revenues. Conspiracy theorists suggested that IBM would cause Linux development to split into hundreds of variants, weakening its ability to succeed in the marketplace. It all seems so fanciful now!

IBM established the Linux Technology Center in 1999 and announced Linux on the mainframe in 2000. Several Linux distributions (distros as old Linux hands refer to them) now run on a mainframe, including SuSE and Red Hat. Other distributions that run on a mainframe include Debian, Gentoo, Slackware, and CentOS. There are also thousands of ISV applications that have been recompiled to run on mainframe Linux. Importantly, Linux is not emulated on a mainframe, it runs as a completely native operating system – like z/OS etc. However, it is most often found running under the king of virtualization, z/VM, allowing multiple Linux systems to run on one lot of hardware.

There is a specialty processor available for Linux – like zIIp and zAAP – called the Integrated Facility for Linux or IFL. This processor runs Linux work, rather than running it on the normal General Purpose Processor (GPP), and so saves the user money because they are only charged for work running through the GPP. Of course, there is the cost of buying (in reality turning on) the IFL specialty processor.

It used to be that every sentence about a mainframe contained a mention of SOA, but nowadays the word is “cloud”. The IBM Web site says: “Cloud computing promises operational efficiency and cost reduction due to the standardization, automation, and virtualization. High flexibility, scalability, and easy management can be provided by the virtual Linux server environment on System z. Which basically says that Linux on System z is a good thing to have in your cloud computing environment because it is an efficient cloud computing platform.

So, happy 10th birthday mainframe Linux (or Linux on System z as we should be calling it). There are apparently 3150 Linux applications enabled for System z and IBM claims that 70 percent of the top 100 global mainframe customers run Linux – so I confidently predict that we will be celebrating its 20th birthday.
