Barry Whyte is a 'Master Inventor' working in the Systems Group. Now based in Auckland New Zealand, Barry is working for the IBM ATS team covering Storage Virtualization for the AP region.

Before I forget I wanted to wish SVC all the best in its 6th year in production. I guess it seems a lot longer, but then I have been (like a lot of the team) working on it for over 8 years now. IBM just celebrated its 50th year at the Hursley site . For those of you that don't know Hursley, its... [Continue Reading]
With the kids having next week off, its time for the trek back up the M6 to Scotland to take them to see their grandparents. After a few manic weeks at work with calls at both ends of the day, I'm off for some well needed rest back in Glasgow. I will reply to any comments when I return.
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...

Over at 'zilla central Mark is discussing the many millions of dollars devoted to research and development products, and in particular how few of them actually make it out into the field as fully fledged products. Back in the late 90's IBM's Research lab in Almaden were busy constructing just such... [Continue Reading]
After a few hectic months, I'd booked a week or so off work so that we could take the kids up to see their grand-parents. I originally hale from Glasgow and my parents still live there. My sister works in Edinburgh as a special-needs teacher and recently had a baby girl, so the plan was during the... [Continue Reading]
I've been head down for the last few weeks, getting a chance to enhance a chunk of code in the middle of the SVC code stack for the next release, the cache. SVC caching is based on an LRU (Least Recently Used) cache model with partitioning added to make things cope with differing capabilities of the... [Continue Reading]
Just over a week or so ago we completed the ITSO Redbook residency to create a book based on the SAN Volume Controller and the IBM FlashSystem 820. Now, normally we like to get these things out very quickly and the team, Danny Bryant, Christian Burns, Joao Marcos Leite, and Denis Senin worked very... [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]
I see that EMC have finally pushed yet another technology family on its customers. Extreme I/O arrays. So now you have to decide which one of these things do I want. OK, let me buy an all flash array, so how will that fit with my VMax and VNX estate - oh it wont - you mean its... [Continue Reading]
I'm sure more than a few of you will know what I mean when I say I've been in "PowerPoint Hell" recently... With various internal executive visits, updates on where we are, where we are going and technical discussion points, its always amusing how much time a decent "slide" takes... [Continue Reading]

In IT... most things are custom... not any more Please do take the time to sign up to the April 11th webcast - it may not be going to crash live blogging, but... [Continue Reading]
Over on eWeek there is a long (24 min) podcast interview hosted by Mike Vizard, and the director of product marketing for IBM System Storage, Charlie Andrews. Charlie explains amongst other things why the rise of virtualization is going to lead to tighter coupling between server and storage... [Continue Reading]
One of the nice things with working on SVC is actually helping customers to solve their day to day storage headaches. We all know and feel the pains caused by the ever increasing amount of storage media needed in our SANs. The management costs, from a people and resource point of view alone start to...

I think its true to say that the SVC and Storwize User Groups that IBM has helped to setup and run has created a real community of users and partners around the globe. There are very active groups in the UK, Germany, France, Belgium, Sweden and Finland and of course the USA. (Sorry if I missed some)... [Continue Reading]
