This is a series of posts that cover the features of Hitachi’s new enterprise storage platform, the VSP (Virtual Storage Platform), also sold by HP as the P9500 array.
The VSP is the first enterprise array from Hitachi that offers support for 2.5″ drives. We’ve seen these Small Form Factor (SFF) models for some time [...]
They say that you learn the most when you make mistakes and things go wrong. Well, last night I certainly must have learned a lot. What started as a simple physical re-organisation of my hardware turned into a rebuild of my production VMware ESXi server – finishing at 1am. Here’s what happened.

Seagate announced this week the release of their new Constellation hard drives. Compared to the Savvio range (which are high-performance, low form-factor), these drives are aimed at lower tier archiving solutions and will scale to 2TB.
I had a briefing on these drives a couple of weeks ago and there’s the [...]
Eric Savitz over at Tech Trader has an interesting article today.
Demand at Seagate is down and consolidation of the industry is expected. However as recently as March last year EMC was telling us how storage growth just keeps on spiralling upwards.
So what’s happening? Are we becoming inherently more efficient [...]
Seagate have announced the availability of the next generation of Savvio 2.5″ drives running at 15K. Capacity is increased to 146GB (I’m waiting for confirmation this is the case as there are no data sheets online yet).
The capacity increase is overdue to keep up with the [...]
Over 18 months ago, I discussed in a post (here) the Hybrid Storage Alliance who were looking to increase the performance of hard drives by adding large amounts of flash to each device. But where are they now?
A quick check on their website shows precious little information. In fact [...]
A question I get asked occasionally is; “How many IOPS can my RAID group sustain?” in relation to Enterprise class arrays.
Obviously the first question is to determine what the data profile is, however if it isn’t known, then assume the I/O will be 100% random. If all the I/O is random, then each I/O [...]
Last week I posted about wasted hard drives, removed from arrays and crushed to prevent the leak of sensitive data.
I contacted HGST and Seagate to get some additional background. Here are their responses, slightly edited to correct any spelling mistakes but otherwise intact.

(a) when will the technology be [...]
Seagate announced yesterday version 11 of their Barracuda hard drive range, to be released next month (August 2008) with a maximum capacity of 1.5TB. The news link has all the speeds and feeds if you’re interested in how they have achieved this remarkable milestone.
I’ve trawled the [...]
