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 a mobile... [Continue Reading]
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 the work...

Its just about year to the day since IBM announced the IBM Storwize V7000, today we've announed the next major step in the evolution of the product, and the SVC code base at its heart. The IBM Storwize V7000 Unified. This integrates IBM's Common NAS software which is used in the enterprise level... [Continue Reading]
Less than two weeks to go before the start of the IBM Edge 2013 conference in Las Vegas. I've finally finished my presentations for the two main sessions I am hosting as part of the Virtualization track Monday 10th 9:30am Session 1610 A Brief History of SVC and Storwize Family : What, How, Why?... [Continue Reading]
I'm busy crafting part 2 of my Configuring for Optimal Performance series, meanwhile check out part two of my interview with Hal Jennings hosting IBM's blog talk radio channel , click on the image below :
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]
These days I'm spending more and more of my time with customers visiting Hursley wanting to hear
about our smart planet initiatives, how we can help to make their infrastructure dynamic and of course
most of my involvement in this is around presenting how and where SVC and storage... [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, and IBM... [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 that... [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]
Well as you have probably read, or heard, the Storwize V7000 is why the SVC team has been so busy over the last 18 months, and why my blogging has been sporadic at best. Hopefully the point of this series of posts is clear, although this is a brand new modular storage box - organically developed by... [Continue Reading]
Tony Pearson has posted a great set of FAQ questions that were answered during a session at last weeks IBM's 2009 Storage Symposium. For any current or prospective SVC users, its worth a read, and it got me thinking I haven't had one of my Q&A posts for a while.. So here is you chance. If its... [Continue Reading]
Yet another couple of weeks go by. July is our busy month at home and with family. 4 birthdays (including my own yesterday), 1 anniversary, and of course the start of the school holidays. For those that follow me on twitter and facebook, the Millenium Falcon was an epic Lego project for Callum and... [Continue Reading]
I thought it was worth spending a few minutes describing a feature that SVC has been supporting for
just over a year now. Call it what you want, "Split Cluster", "Split I/O Group", "Hyper-swap", "Pork"
(Sorry HAM). After HDS made such a wet fish splash... [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]
Hi all, lots of posts coming I promise, lets start with the most pressing, the next UK SVC/V7000 user group meeting. Open of course to end users from across the globe : Where and when : 11th July 2012 at IBM Hursley Park, Winchester Abstract : During the day you will be able to informally... [Continue Reading]

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]
Hi all, Yet again, been a few weeks since i last posted, but we've been busy, and all will become clear soon. Meanwhile, in-case you didn't know some of the benefits SVC, V7000 and inband virtualization can provide, click on the image below to have a listen, or download the first part my chat with...

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 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]
Well I'm almost recovered from the hectic day yesterday. My day started with the train from Southampton at 6:30am to get up to London in time to prep before the first session of the day. Before I get too far, thanks to all that came along to the UK Launch event at Tate Britain - it was great to see... [Continue Reading]
2000-2007 The "Virtual" Storage - SAN Virtualization Appliance Years First of all thanks again for all the feedback regarding this series of posts, great that people are enjoying a bit of a history lesson, or even a reminder into your own histories!
So where was I... The Hursley team... [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 most... [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 many... [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]
The kids very kindly passed on their latest 'bring-home' from school - a stinking cold! Been feeling pretty rotten since I got back
from SNWE in Frankfurt a couple of weeks back - so hopefully I didn't pass it on to anyone I met there! Was a great couple of days,
thanks to everyone that came... [Continue Reading]
Seems like a lot of water, in the case of Farley and Burke - a lot of smack ups - but it feels like smack downs to me... ;) has gone under the bridge. Looking back at my first part work, some 24 months ago, it would look like Invista was still maybe being banded about as a 'serious' option, and many... [Continue Reading]
