Recently we published an IBM Redbooks Solution Guide on Implementing IBM Easy Tier with IBM Real-time Compression.
IBM® Easy Tier® is a performance function that automatically and non-disruptively migrates frequently accessed data from magnetic media to solid-state drives (SSDs). In... [Continue Reading]
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]
One of the internal, and IBM Business Partner mailing groups I subscribe and participate in ( Hi to all on Diskcore ) recently debated :
Want to know whether IBM V3700 are true symmetric active active controllers.
A response was made, but also asked :
Can you define... [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... [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]
Hi all, lots of posts coming I promise, lets start with the most pressing, the next UK SVC/V7000 user group meeting.

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]
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...

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 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]
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]
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]
For those of you in the UK, a chance to come along and see us at the SNIA Datacenter Academy event on 19th May in the QEII conference Centre.

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]
Greetings one and all! I am still alive, some months have passed, but I'm still here and should be back to regular posts now!
