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 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.

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. I...   [Continue Reading]

You may have already seen that SVC has yet again set a new world record benchmark when it comes to the Storage Performance Council's SPC-1 benchmark. The initial planning called for a full eight node test - as we normally do, and the manufacturing requests were put in to setup the 4000+ HDD...   [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]

I've just been through some of our detailed results for 4Q, given that we only announced availability of the new CF8 hardware back in November and exceeded expectations with their adoption. Over the quarter Tivoli Storage Software, which SVC comes under, saw double digit growth. The up-take of the...   [Continue Reading]

Two posts in one week. Doing well. I set one of my resolutions this year to post at least once a week – hence my new numbering scheme. Maybe I’ll use the fact that 2010-2.2 and further double posts count for the odd week I may miss :)   Benchmarketing. It’s a dodgy term, and even dodgier maths. We...   [Continue Reading]

A lot of you may have seen the NASA satellite photo of the UK last week, certainly you can't deny that the snow has hit pretty much the whole country, the contrast compared to a normal satellite image is quite amazing.

 Happy New Year to all. As you may know, or have seen the UK is currently under the grip of winter. A few inches of snow and the country comes to a stand-still.

 As this is my last day in the office until the new year, I thought I'd take a few minute to quickly wish all my readers all the best over the Festive season.

 I know, I know,.... Or even I know I haven't posted enough when I caught up with a few customers this week and they all comment - "your blog has been quiet, a good few indepth posts, but not the usual post rates" I won't give any excuses, you've heard them all before, but I have actually...   [Continue Reading]
