The "modular monolith" has arrived. Oh how the EMC spin doctors must have jumped for joy when they realised the next version of the almost 20 year old Symmetrix family, the DMX-5 could also mean DMX-V in roman numerals. Better still lets try and jazz it up furter, how about DMX V-"Max". Oh how... [Continue Reading]
Over at Burke HQ , I see that he's a little put out by a few questioning articles after EMCs 1Q broadcasts. In his latest post titled "Lions and Tigers and Bears" I can only but say "oh my!" Its unlike BarryB to tee himself up for such an obvious retort and to use his words not mine, let me explain.... [Continue Reading]
Its been so difficult to keep all this to myself over the last few months, especially last month when we actually reached our goal. 1 Million real life IOPs at less than 1ms - no caching, just pure raw performance. You may, or may not have seen the IBM press release , covering the first part of... [Continue Reading]
Just back from a nice relaxing break over the holidays, while keeping one eye on things since the start of the week. It was nice to start back on a Friday though, as it meant I could catch up on the email, sort out a few hosts and drives that had died under the onslaught from two solid weeks of...

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]
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]
You may have already seen that SVC has yet again set a new world record benchmark when it comes to the Storage Performance Council's SPC-1 benchmark.
The initial planning called for a full eight node test - as we normally do, and the manufacturing requests were put in to setup the 4000+ HDD... [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 still haven't finished sorting out the photos from the German SVC User Group session I attended last month, but here is your chance to come and visit us in IBM Hursley, the home of SVC development.
This event is open to SVC users, primarily in the UK, however if you fancy a trip to the UK in... [Continue Reading]
I wrote this a few weeks back - was waiting for the right time to post - and for once it seems Hu and I are coming from the same place!
Its likely a lot of my regulars have heard of Yotta Yotta. To all extents and purposes they produced and interesting SAN cache prototype. It used lazy... [Continue Reading]
So after all the EMC hype, and all the claims that the DS8000 was "pushing up daises" it seems
that IBM have managed to announce the GA of ship our sub-lun hot-spot management, aka Easy Tier before EMC
have shipped their FAST function.
Now, before you all jump and say EMC have been... [Continue Reading]
Just a very quick post to remind anyone who hasn't yet registered for the first UK based SVC User Group Meeting in Hursley on the 11th May to get yer finger out. There are just a few places left for your chance to hear whats coming, and more importantly for us to hear what you want. See my original... [Continue Reading]
I just wanted to post a quick thanks to everyone that took the time out of their day jobs to come to Hursley yesterday for the User Group sessions. I'm hoping that everyone got as much as we did out of the day and it was great to see so many (not just UK) visitors. I've already started pushing... [Continue Reading]
I knew it had been a while, but I wouldn't have guessed it was 14 weeks since I last posted.
Nothing much changes thought, the NetApp fan boys are being just as defensive as ever, EMC (well Mr Symm) are still spending as much time writing about IBM and its dieing products, if DS8000 had died as... [Continue Reading]
The "Shark" and FC-AL Years - 1998-present
Last time I briefly covered the Hursley Storage team's work on the 7133 - Serial Storage Architecture products. Thanks for all the emails about this, and I'm glad people still remember it - fondly?! Those screwdrivers - and Martin, i think... [Continue Reading]
