Yet another couple of weeks go by. July is our busy month at home and with family. 4 birthdays (including my own yesterday), 1 anniversary, and of course the start of the school holidays. For those that follow me on twitter and facebook, the Millenium Falcon was an epic Lego project for Callum and... [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]
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]
With the move to the new blog software, there is probably a bunch of you that found yourself here, not knowing what this post was going to contain - as well as my regulars that either reap the benefits of SVC every day, or know the patter , but may not know all the benefits.
I liken SVC to... [Continue Reading]
I thought it was worth spending a few minutes describing a feature that SVC has been supporting for
just over a year now. Call it what you want, "Split Cluster", "Split I/O Group", "Hyper-swap", "Pork"
(Sorry HAM). After HDS made such a wet fish splash... [Continue Reading]

As you may have noticed, they've moved us all over to the new MyDeveloperWorks website. Still getting to grips with it myself, need to get my profile pics and stuff copied over, but the redirect URL is in place already!!! All my hit counts are gone, the technorati score and everything else... [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 "modular monolith" has arrived. Oh how the EMC spin doctors must have jumped for joy when they realised the next version of the almost 20 year old Symmetrix family, the DMX-5 could also mean DMX-V in roman numerals. Better still lets try and jazz it up furter, how about DMX V-"Max". Oh how... [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]
A few days late with my welcome, I'm sure when the clocks went forward a couple of weeks ago someone also stole one day from every week, it feels like that at the moment - just not enough hours to get everything done at work and at home - maybe I should stop playing with Callum and his Lego so...

Funny, I had been thinking about blogging about a customer visit I had this week, primarily a new SVC user wanting to discuss and go into some deeper technical insight into the product. I enjoy these days as its a chance to talk techy with someone who is actually using and hopefully benefiting from... [Continue Reading]

A work colleague asked if is RSS feed for my blog was broken the other day. Things have been sure crazy for the last few weeks - thats always my excuse! I did have this post in the sidelines, and wanted the mud slinging to stop before I set the record straight. Well, you can probably guess who's... [Continue Reading]
Following last Septembers "Information Infrastructure" launch, IBM today announced wave two subtitled Dynamic Infrastructure . The press release covers some of the higher level details, and a new "DI" portal has been created on the IBM website. From a disk and storage perspective the DS8000 gets... [Continue Reading]
