... a mid-term interrupt... The storage system behind IBM's PureFlex, PureSystems recent announcement, is of course the IBM Storwize V7000 controller... Check out more details at http://www.ibm.com/ibm/puresystems/us/en/index.html#tab:overview/subtab:default (Hence all my expert video posts over... [Continue Reading]
The Serial Storage Architecture Years - 1990-1998 Its been a crazier than ever year. All will become clear soon. But one of the things I wanted to discuss with you all is just what kind of history comes with the team of ~150 storage people that I work with on a daily basis. Of course there are a...

After a couple of weeks of car hell, that resulted in the entire removal of the intake manifold, just to get to the darn crappy sensor that had packed up (and Land Rover informed me was the 3rd re-design - in any other business that would mean ' 2x faulty design) but anyway, thanks Geoff for the...

As we approach SVC's 6th birthday its interesting to see the rest of the industry starting to catch up and realise not only that a modular commodity storage controller is the way forward, but that also clustering of said modular controllers has many benefits. We all await todays announcement of HDS... [Continue Reading]
When Nigel asked the question about IBM's age in Infosmack 101 I was initially amazed hat everyone didn't instantly know that IBM is 100 this years young this year, next week infact.
I guess internally we've had a lot more press about this than there has been externally. Anyway, on 16th June... [Continue Reading]
There has been a lot of twitter banter, and blog posts about Tiering. Netapp claiming you don't need
to tier, EMC and IBM saying tiering is important and 3Par Farley going so far as to say that Netapp
can't do tiering easily, hence their response, and discussion of PAM being the way to resolve.... [Continue Reading]
I've just been through some of our detailed results for 4Q, given that we only announced availability of the new CF8 hardware back in November and exceeded expectations with their adoption. Over the quarter Tivoli Storage Software, which SVC comes under, saw double digit growth.
The up-take of... [Continue Reading]
Two posts in one week. Doing well. I set one of my resolutions this year to post at least once a week – hence my new numbering scheme. Maybe I’ll use the fact that 2010-2.2 and further double posts count for the odd week I may miss :)
Benchmarketing. It’s a dodgy term, and even dodgier... [Continue Reading]
A lot of you may have seen the NASA satellite photo of the UK last week, certainly you can't deny that the snow has hit pretty much the whole country, the contrast compared to a normal satellite image is quite amazing.

Happy New Year to all. As you may know, or have seen the UK is currently under the grip of winter. A few inches of snow and the country comes to a stand-still. Maybe I'm getting old an cynical (some may say no maybe about it!) but I do remember walking to school in drifts of over 2 foot back in... [Continue Reading]
As this is my last day in the office until the new year, I thought I'd take a few minute to quickly wish all my readers all the best over the Festive season. I've already set one of my new year resolutions to make time to blog more - so all being well, I'll be more active on here next year,... [Continue Reading]
I'm sure more than a few of you will know what I mean when I say I've been in "PowerPoint Hell" recently... With various internal executive visits, updates on where we are, where we are going and technical discussion points, its always amusing how much time a decent "slide" takes... [Continue Reading]
I find I start so many posts these days describing how busy I've been as an excuse to why my post
frequency has been lower than normal. This has to have been a new record as I spotted my last post was over a
month ago. This time however I do have a much better excuse, two weeks time off away... [Continue Reading]
I've been head down for the last few weeks, getting a chance to enhance a chunk of code in the middle of the SVC code stack for the next release, the cache. SVC caching is based on an LRU (Least Recently Used) cache model with partitioning added to make things cope with differing capabilities of the... [Continue Reading]
