There has been a lot of twitter banter, and blog posts about Tiering. Netapp claiming you don't need
to tier, EMC and IBM saying tiering is important and 3Par Farley going so far as to say that Netapp
can't do tiering easily, hence their response, and discussion of PAM being the way to resolve.... [Continue Reading]
With half term week here in the UK and preparations for next months travels, I almost forgot that yesterday we announced the contents of version 7.4.0 of the SVC and Storwize software that will be GA'd on 28th November.
The full RFA can be viewed here , but here's a quick summary.... [Continue Reading]
Starting with IBM Storwize Family Software V7.2, including IBM SAN Volume Controller, we introduced native replication over IP networks. As this IBM Redpaper describes, you will see that it is easy to configure in an existing IP infrastructure. This is a lower-cost alternative to the Fibre... [Continue Reading]
It was nice to have a day back in the office today, the last couple of weeks have gone by in somewhat of a blurr, with several offsite customer visits, several more visiting Hursley, my vLab sesson at IP expo in London , then last week in Germany at the SVC User Group in Mainz and finally all...

I think that this Heartbleed bug is going to be an observational comedian's dream. Well I guess one that is a bit of an IT geek anyway. Not quite sure what the Pub Landlord will make of it, but I am sure that he will have some kind of an opinion. Probably not fit to print.
Anyway, on to... [Continue Reading]
While googling I spotted an interesting topic from Chris, discussing the application of SATA drives in the enterprise. Quite rightly for years most vendors have been telling their customers that SATA is no replacement for SCSI or Fibre-Channel enterprise class disks. I don't know enough about the...

I wrote this a few weeks back - was waiting for the right time to post - and for once it seems Hu and I are coming from the same place!
Its likely a lot of my regulars have heard of Yotta Yotta. To all extents and purposes they produced and interesting SAN cache prototype. It used lazy... [Continue Reading]
Its been a while since I opened up this blog.forum for anything you wanted to ask.... IBM has been in the tape and disk market for more than 60 of its 100 years... so where do we think its going? What do you think? and where do you see SVC and the new V7000 fit in your needs? What do you want from... [Continue Reading]

This post covers : SEV Implementation Details SEV... [Continue Reading]
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

Since my blog was moved from the old Developerworks site into the myDeveloperWorks framework I've been trying to get some widgets back and reset the theme. It seemed like beyond the scope of what the interface the new framework provides... until I found the hidden menu that appears when you change... [Continue Reading]
A couple of weeks back I got together with Nigel and Rick over at Infosmack , spending some time discussing what got me into computing, how I ended up in storage and what its like to work in IBM. I have to admit that I did go and get my old BBC Model B out the attic and have a night or too messing... [Continue Reading]
Looking back through my posts its been some months since I last opened the floor to you all, so here is you chance, a free floor. Ask anything you like, about SVC of course, but if I don't know I'm sure I know someone that will. Recently I've heard some quite elaborate FUD from the usual suspects,... [Continue Reading]
