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]
As you may have seen, today IBM announced the next product in the Storwize family, the IBM Storwize V3700.
The Stowize V3700 builds on the amazing success that the Storwize V7000 has seen in the last two years- and of course SVC has had in the market for almost 10 years now. I could use... [Continue Reading]

I see that EMC have finally pushed yet another technology family on its customers. Extreme I/O arrays. So now you have to decide which one of these things do I want.
OK, let me buy an all flash array, so how will that fit with my VMax and VNX estate - oh it wont -

As I try to get back to more regular posting, Part 3 of Configuring for Optimal Performance is getting its final polish to post hopefully next week. Meanwhile its some time since I opened this up for your questions. This is Q & A #5, so feel free to ask away. Obviously I can't discuss... [Continue Reading]
I guess a few folks will comment that I'm raising my head again at announcement time, and true, but thats part of the problem on working on new and exciting stuff, I can't talk about it until days like today where we have announced two major new engines in the SVC and Storwize family. I even... [Continue Reading]
We are delighted to announce an exciting addition to the distribution channel of IBM Redbooks – now available at the Apple iBookstore is the ability to download, for free, (I probably should add some disclaimer about network charges may apply so this is it!) selected books. Not all books... [Continue Reading]
Some of you may have spotted we release another Storwize Family member back in July, but in limited geographies. Today

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]
Just over a week or so ago we completed the ITSO Redbook residency to create a book based on the SAN Volume Controller and the IBM FlashSystem 820.

With the move to the new blog software, there is probably a bunch of you that found yourself here, not knowing what this post was going to contain - as well as my regulars that either reap the benefits of SVC every day, or know the patter , but may not know all the benefits.
I liken SVC to... [Continue Reading]
I thought it was worth spending a few minutes describing a feature that SVC has been supporting for

(Sorry HAM). After HDS made such a wet fish splash... [Continue Reading]
