And back again

The first one didn’t work, here is a another trackback

Testing trackbacks from cathcam

I’ve posted two trackbacks this week to non-Wordpress blogs and neither showed up. This is a test to see if they show up here…

I’m a “centerprise” architect, no honest, I am!

After some intense work on a couple of key futures projects, one on SOA and System p; the other on processor threading architectures; I had a couple of minutes today to catch-up with some of my RSS feeds before heading out the door and catching the last flight up to NY for the annual IBM STG Senior Leadership meeting.

Two things in the feed list grabbed my attention, both from RedMonk, although one from the self-appointed RedNun(dangerously close to something I grew to loathe in the seventies, Blue Nun, but that’s another story).

First, James Governor “outed” me and my new business cards on the Mainframe blog. I didn’t so much the resent the outing, I think it was the notion that I’d gone from zSeries to System p that hurt. I never saw it that way, I’ve just come over to System p to do a job, it’s just technology mate.

Then I read Annes’ useful piece on Open Source ESBs and Decentralised SOA development. For an op.ed piece I’m with this entirely and not about to leap to defend the usual suspects. However, reading it I just couldn’t get past the words “decentralised” and “distributed”. In IT these are emotionally loaded terms. Continue reading ‘I’m a “centerprise” architect, no honest, I am!’

Security in Power5 LPARs

A recent discussion on the value of infrastructure virtualization for SOA and SOA based middleware and related security issues was one worth posting on.

It seems to be a commonly held view that we really won’t get true Internet, Web security isolation for servers until we get the next generation of Intel hardware and related software updates from Linux and Microsoft and a protected kernal or nexus.

That overlooks the fact that System p already delivers features that enable hardware isolation that can protect software running in one logical partition from a). being hacked and b). if it is hacked, being able to compromise other partitions either directly or indirectly.[1] Continue reading ‘Security in Power5 LPARs’

Getting help on Advanced Power Virtualization

Keith and Gerry both emailed me and both asked, in different ways, about getting some help on Advanced Power Virtualization. Today we announced a focussed services offering, but there are lots of other resources to help you understand and get started.

  1. An easy place to start is this guided, no-charge, introduction presentation ? You can view online or download.
  2. There are currently a set of 2-day “no charge training workshops being run in India, the US and the UK. Details here.
  3. If you miss the workshops, or perhaps want to do a deep dive and get some hands on, as well as best practices, IBM Education offers a 4-day “System p LPAR and Virtualization II: Implementing Advanced Configurations” class AU780. IT is running eight times in 1Q07 in the USA. Details here.
  4. For those who want to read, rather than attend, the ITSO as always offers a wealth of online reference material. There is material that covers the basics, the recent changes and enhancements, and a 10/06 Best Practices book. Search here.

Finally, if you would really feel more comfortable letting someone else do the work and learning from them as they do it, today IBM Services announced “IBM Implementation Services for System p — Advanced POWER Virtualization”, if you want to go down this route, you’ll need to talk to your IBM Rep.

In search of partitioning

In his Enterprise Architecture: Virtualization and Management by Magazine blog post, James McGovern muses on mainframe virtualization leadership and if the likes of James Governor and the 451 Group will start blogging about it. He also wonders if “IBM mainframes would make a better participant in a grid architecture than Sun, Dell or HP?”

It’s not clear where the link is to management by magazine, but the blogsphere is certainly a funny old world. Partitioning and virtualization is taking off in a big way and a few short clicks this is all back in focus. Continue reading ‘In search of partitioning’
