In the final part of my 'How it Works' series I'm looking at upgrades. Both software and hardware. Maintenance Windows As the world has moved to a 24x7x52 culture, nobody can really afford many, if any, 'maintenance windows' these days. I described in part2 that to move from a non-virtual to a...

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

How well are you handling the information explosion? Can your storage infrastructure handle the next growth phase? Success in today's business climate will require a dynamic information infrastructure that is highly available, responsive, efficient and cost effective. In this webcast, hear how...

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... [Continue Reading]
As this is my last day in the office until the new year, I thought I'd take a few minute to quickly wish all my readers all the best over the Festive season. I've already set one of my new year resolutions to make time to blog more - so all being well, I'll be more active on here next year,... [Continue Reading]
Talk to any storage or system administrator and one of their major pain points (after data movement pains) is making A work with B and keeping C at the right firmware level so that A works with C as well as B and so on. Sometimes this just isn’t possible and can lead to infrastructure ‘exceptions’... [Continue Reading]
I can't help it. It seems that every post that Mr Yoshida makes strikes me as being somewhat questionable. I have much respect for how long he has been in the blogging game. I have no respect for his lack of reader comment acceptance - I've long since given up replying as he decides to ignore those... [Continue Reading]
I'd like to at least take my hat off to HDS for once. I have been laying into them with apparently car salesman like maths , but then it had to be said. So why this sudden note of appreciation. For stepping up to the mark and submitting their USP-V to the Storage Performance Council , SPC-1... [Continue Reading]
Back in June Chris Mellor stirred up a few people by suggesting that an unnamed source (I'm guessing someone at DataCore with a chip on their shoulder) was claiming IBM and HDS stole, or even reverse engineered the product to produce our respective SVC and USP products. Tony Pearson quite clearly... [Continue Reading]
Today marks the next phase, or the beginning of a series of announcements, previews and strategy updates from IBM Storage.
The splash page for todays launch is
over on the storage news pages - this includes R4.3 of DS8000, adding thin provisioning for open systems and mutli-track support for... [Continue Reading]
The SPC contacted SUN regarding violations of the SPC 'fair-use' terms. To that end, John and Valdis have retracted both the newsletter comments and blog posts that claimed 'faster than SVC' therefore the links in this post no longer show their original content. I have left this post in place for... [Continue Reading]
Just a quick one - while having a scan through IBM's new(ish) ability to review products on its main website, I found this :
It did make me chukkle... its cetainly no Invista either - and... [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. I've provided a link (the image) to the IBM customer / end user registration page, please register and come along on the day. This event is aimed at end... [Continue Reading]
With the GA of IBM SAN Volume Controller (SVC) v4.2.1 only a couple of weeks away, its been the usual last minute rush to get the last few code changes benchmarked on my performance stand. Luckily the set of scripts and tools I inherited, and have modified over the years, allow 24x7 benchmarking,... [Continue Reading]
Just a quick one to point you to the latest attempt from Chuck Hollis to spread more FUD about Storage Virtualization and why he wishes it would go away. I can tell you why he wants it to go away, and its nothing to do with the arguments he lays out... There is some interesting discussion in the... [Continue Reading]
