This is a bit of an opus I'm afraid, but I've had my hands tied for so long in what I could / couldn't say so think of this as a catch up for my last 6 months of sporadic posting! Please do try to make it to the end, I'm covering a lot here!
In my last post I covered whats coming with SVC 5.1... [Continue Reading]
There are two reasons that my blogging this year has been sporadic at best. One, the sheer volume of work, its become the norm at the moment for the whole team to be spending evenings and weekends working on our baby.Why have we been all so dedicated over the last year or so, mainly because we've...

I've been waiting for what seems like far too long for this series of posts. The development and test teams have been working flat out for the last year to bring SVC 5.1 to market.
Today IBM issued a press release detailing a little of whats coming next month with SVC release 5 software, the... [Continue Reading]
As we approach SVC's 6th birthday its interesting to see the rest of the industry starting to catch up and realise not only that a modular commodity storage controller is the way forward, but that also clustering of said modular controllers has many benefits. We all await todays announcement of HDS... [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]
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]
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]
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]
So after all the EMC hype, and all the claims that the DS8000 was "pushing up daises" it seems
that IBM have managed to announce the GA of ship our sub-lun hot-spot management, aka Easy Tier before EMC
have shipped their FAST function.
Now, before you all jump and say EMC have been... [Continue Reading]
I see that Hu thought he'd better make up some mumbo-jumbo about their 'chubby-provisioning' solution. I did post a comment but, as usual, his moderating means he ignores comments he doesn't like. I'd point you back to my discussion about random 4K writes randomly across a large volume, say one hits... [Continue Reading]

The Serial Storage Architecture Years - 1990-1998 Its been a crazier than ever year. All will become clear soon. But one of the things I wanted to discuss with you all is just what kind of history comes with the team of ~150 storage people that I work with on a daily basis. Of course there are a...
