  • Location does sometimes matter

    ORIGINALLY POSTED 5th February 2008 10,102 views on developerworks One of my regular blog stops is over at Techworld where Chris Mellor discusses all things storage. I spotted an interesting post from Chris today comparing SVC to USP and coming up with the conclusion that the two are almost the same in what they can [Read More]

  • Can’t wait for the excuses

    So before Mr Burke, Chuck or the zilla get in there with the excuses let me have a guess at what’s coming : They deliberately mis-configured it Its not a true comparison Its not a real life workload Its all about the number of drives color=greenad infinitum… I am of course talking about the latest [Read More]

  • One box fits all – or does it? A discussion of tiering.

    ORIGINALLY POSTED January 21st 2008 13,232 views on developerworks I’m in the middle of another take on the – Why Virtualize? story – looking at it from a subtly different angle – more of that later this week hopefully.

  • Productivity Center 3.3, Striping and Performance

    ORIGINALLY POSTED January 10th 2008 10,649 views on developerwortks I’d mentioned we (the SVC performance team) have a few bits of fine tuning and investigations to perform for the next (4.3.0) release of SVC.

    ORIGINALLY POSTED 21st Decvember 2007 10,182 views on developerworks The house is feeling quite Christmas-e, with the tree and lights having been up for a few weeks, the collection of presents under the tree growing and the usual ‘spring cleaning’ sessions before the big day. One more day to go, and yet another working year [Read More]

  • Deja-vu – Invista 2 – again?!

    ORIGINALLY POSTED 15th December 2007 7,792 views on developerworks Back in August I posted about the ‘Stealth’ announcement of Invista 2.0. It seems that our friends over at EMC decided that after almost 6 months, they’d try again and actually tell the world this time. I thought I’d wait till the end of the week [Read More]

  • Vanilla Windows vs Embedded Windows

    ORIGINALLY POSTED 5th December 2007 8,268 views on developerworks I guess I didn’t really get the message across in my previous post, well certainly not in the way I inteded from the emails and comments here.

  • Would you trust Windows to Virtualize your Storage?

    ORIGINALLY POSTED 2nd December 2007 12,831 views on developerworks 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 [Read More]

  • What’s wrong with Storage Virtualization 1.0?

    ORIGINALLY POSTED 30th November 2007 12,255 views on developerworks 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 [Read More]
