It is hard to look anywhere these days without seeing Flash being used. I think the word that marketing like to use, unless it has fallen out of favour is "pervasive". Mind you in the hands of some people it is definitely moving from "pervasive" to "invasive" but... [Continue Reading]
Last week I had a couple of meetings in Manchester (UK) with some SVC and V7000 end users, as well as the chance to pop in and say hi to our team in the IBM Manchester labs. About two days before heading up the M6 I was asked if I'd like to join in a roundtable session with UKFast - discussing the... [Continue Reading]
Configuring IBM Storwize V7000 and SVC for Optimal Performance Part 2
Thanks to everyone who responded to my Part 1 post, I'm amazed at how many people must read what I have to say! Based on the number of you that have either spoken to me in person, or emailed. I'm glad to be of some use

As you may or may not have seen, IBM has agreed to acquire Texas Memory Systems : http://www-03.ibm.com/press/us/en/pressrelease/38594.wss This has many implications (all good) for SVC, Storwize V7000, and Pure Systems. Better integration with existing RamSan products, and of course integrated... [Continue Reading]
One of the key benefits of the Storwize V7000 product is its built in Virtiualization capabilites. Or as some vendors like to call it Federation?
Its been almost 9 years since we first released SAN Volume Controller (SVC) and in that time, its been through 6 hardware iterations, and 16 major... [Continue Reading]
Configuring IBM Storwize V7000 and SVC for Optimal Performance Part 1
I've been involved in a quite a few pre-sales, proof of concept and after-sales accounts where people have setup their V7000 and then wondered about the performance they are achieving, is it optimal, can they do... [Continue Reading]
Well, i guess I should first wish, any readers I still have left a Happy New Year. Not only are we now into 2012, but hey its February too, where did January go... must be some kind of temporal locality thing going on (private joke - sorry, all will become clear all too soon)
For those of you... [Continue Reading]
At the risk of re-gurgitating recent Storage benchmarketing scars and rumblings, its probably escaped most people that we just published another Storwize V7000 SPC-1 benchmark. Why another I hear you ask, well the first one we published was back in November when the product first GA'd.
However, we... [Continue Reading]
It was nice to have a day back in the office today, the last couple of weeks have gone by in somewhat of a blurr, with several offsite customer visits, several more visiting Hursley, my vLab sesson at IP expo in London , then last week in Germany at the SVC User Group in Mainz and finally all...

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]
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]
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]
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]
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]
