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]
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]
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]

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]
On Friday we will release SVC software version 6.4 - it used to be simple, I could just reference SVC, but of course the same software package can be installed on V7000 systems. At present V7000 Unified systems remain at 6.3 features and functions.
You've probably seen the news in the press,... [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]

just a quick one... In every day life, we have appliances, or white goods, simple and easy to use, they do the job we need of them... In IT... most things are custom... not any more Please do take the time to sign up to the April 11th webcast - it may not be going to crash live blogging, but... [Continue Reading]
A couple of weeks back I got together with Nigel and Rick over at Infosmack , spending some time discussing what got me into computing, how I ended up in storage and what its like to work in IBM. I have to admit that I did go and get my old BBC Model B out the attic and have a night or too messing... [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]

The IBM Storwize V7000 Unified. This integrates IBM's Common NAS software which is used in the enterprise level... [Continue Reading]
While catching up on some old and new posts out here I came across an interesting article from Chris Mellor discussing a report about various PCIe card benchmarks performed by the Swiss National Computing Centre (CSCS).
I was going to reply to his post but as I started typing realised I had a... [Continue Reading]
I am still alive. I know I've been crap at posting for the last year or so, and really when it comes to it, I'm not going to say I'm sorry... for those of you that like sci-fi, and are of a certain age... those of you that watched Star-Trek Voyager when it first aired, will remember the half...

Greetings this week from the Storage Buddhist as I do a guest spot on this blog for Barry. I'm wondering if he's a little sensitive about Nigel Poulton 's recent Infosmack jibe about how often this blog gets updated, so I'm stepping in while Bazza contemplates possible topics for his next blog...

I mentioned in the summary for 6.2 that we now fully support the VMware VAAI protocols, check out Anthony's blog for a great write up and some real life customer experience using vMotion and SVC offload. ... [Continue Reading]
Its been a while since I opened up this blog.forum for anything you wanted to ask.... IBM has been in the tape and disk market for more than 60 of its 100 years... so where do we think its going? What do you think? and where do you see SVC and the new V7000 fit in your needs? What do you want from... [Continue Reading]
As I previewed back on the 9th May, the new 6.2 version of the SVC software is now generally available (GA in IBM speak). This software not only supports the latest generation of SVC CG8 node hardware, but the new Model 300 versions of Storwize V7000 - 8x 8Gbit Fibre ports, 4x 1Gbit iSCSI and now... [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]
I’ve been traveling quite a bit over the last couple of months, both business and pleasure. Large amounts of this, especially the business travel has been in the car where I’ve been enjoying the use of the USB port in the glove box to upload mp3 files to the inbuilt flash drive in the car. Yes even... [Continue Reading]
As hinted by my last post, the next release of SVC software is on its way, available in early June, along with the new optional 10Gbit iSCSI support. Since SVC, and V7000 are essentially the same thing, just packaged in different hardware vehicles, all of the software updates apply to both... [Continue Reading]
