Off The Grid

I've been on holiday for the last week (sunning myself and the family in Cyprus). I had no Internet access - not even TV! Although I had no laptop (or Blackberry this time) I did take my iPod Touch, now configured with the mobile version of NewsGator. As I've mentioned previously, I have a 100+ RSS feeds (which I'll publish once I get around to it) on storage and others. My backlog was about 2500 entries, so I decided to challenge myself to get up to date and read as much as possible. Clearly I didn't read them all (there were plenty that could be skipped) but I read most and it provides for an interesting cross section...

EMC - blogs are run like a military machine; co-ordinating the news relating to new product releases and mercilessly hammering the competition. EMC have more storage bloggers than any other storage company and there are some good ones out there - one of my favourites is Information Playground by Steve Todd, where he discusses the design of Clariion.

Netapp - follows a close second to EMC with lots of bloggers and lots of competitor bashing. I particularly like Alex McDonald's postings.

IBM - doing a great job running the "resistance", fighting back against the continual onslaught of Barry (A Burke). Check out Barry (Whyte) and Tony Pearson. I'd like to see more from IBM though, especially their product developers working on DS arrays and XIV.

HDS - A jolly good bloke, but not really a player in the blogosphere. Only Hu contributes regularly, but doesn't engage in any serious debate.

Sun - quite literally on another planet with their storage strategy!

Dell - bought some toys, but doesn't know how to play with them. Unfortunately the older boy who could help them play with them has left...

Now there are more companies out there and I don't think I have any blog links from Brocade, 3Par, Compellent, Emulex, Qlogic, Pillar and others although I may be wrong (it is getting late). Any RSS link offerings gladly welcome - although I might not get around to reading them before my next holiday!

USP-VM

Hitachi has announced (10th September) the availability of a new storage array, the USP-VM. At first glance this appears to be the USP-V equivalent of the NSC55 as it has very similar characteristics in terms of cache cards, FEPs etc. Unfortunately HDS have provided links to specification pages not all of which include the USP-VM references. Bit sloppy that.

I've previously deployed a number of NSC55's and within 6 months wondered whether they were the right decision. They weren't as scalable as I needed and there were a few features (such as BED ports and FED ports sharing the same interface card) which were a bit of a concern (imagine losing a FEP and having to take 1/2 of all your BE paths offline to fix the problem). I'm always reminded of the DMX1000/2000/3000 range when I think of the NSC model as these EMC arrays weren't expandable and of course a DMX1000 quickly filled up....

Hu describes the USP-VM as "Enterprise Modular" in his blog entry. This may be a bit generous as (a) I doubt the USP-VM will be priced as low as modular storage and (b) I don't think it will support the whole range of disks available in a modular array. I say "think" as the link to the capacity page for the USP products doesn't yet include the USP-VM.....
