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]
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]
I find I start so many posts these days describing how busy I've been as an excuse to why my post
frequency has been lower than normal. This has to have been a new record as I spotted my last post was over a
month ago. This time however I do have a much better excuse, two weeks time off away... [Continue Reading]
“To err is human; to forgive, divine.” Alexander Pope.
Well we are mixing up poetry and Star Wars here today (or tomorrow, if it is already tomorrow where you are), and finish it off with a cryptic message.
Anyway, let's cut to the chase here: a long time ago, in an IBM... [Continue Reading]
Its been so difficult to keep all this to myself over the last few months, especially last month when we actually reached our goal. 1 Million real life IOPs at less than 1ms - no caching, just pure raw performance. You may, or may not have seen the IBM press release , covering the first part of... [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]
As most people are aware (see Barry's post) we just announced the Storwize V5000. It fits neatly between the Storwize V3700 and the V7000.
And of course no product is complete without an accompanying IBM Redbook.
So, here goes:
One new one:

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...

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]
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]
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... [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]
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]
Your Personal Invitation to the SVC and Storwize V7000 User Group Meeting
This is an unrivalled opportunity for you to meet with and talk to IBM’s leading SVC and IBM Storwize V7000 subject matter experts. Our team will formally present their views on the strategic directions of SVC and... [Continue Reading]
The interop just keeps growing. As you would expect you can today attach the new IBM Storage products behind SVC, running the latest 4.3.0 software. SVC has actually supported XIV since August, we completed the controller qualification during our last SVT cycle, and the IBM Storage teams in the US... [Continue Reading]
