It’s hard to believe that over three years ago I asked a question on where
hybrid drive technology had reached. I was thinking of the Enterprise
market at the time and as far as I am aware, at this stage, no Enterprise
storage array manufacturers have yet integrated these devices into their
products. At the consumer level, of course there are products out there,
most well known being Seagate’s Momentus XT drive. But there is another
approach to speeding up the hard drive and that’s to use SSD as a cache but
in a slightly different manner. A good example of this is the OCZ Synapse
SSD drive which uses software to provide the cache intelligence.
Imagine a typical hybrid drive. Data written to and from the drive will be
in blocks matching the solid state component, let’s say 4K blocks. There
aren’t many alternatives to cache management other than to use Least
This morning I signed up and had a play with Microsoft Labs’ social media
application, so.cl. This was quietly released over the weekend with little
attention as it’s a piece of experiment work rather than a new social media
platform. It’s early days to be commenting on whether so.cl will be
useful; currently it appears to be targeted at students and search sharing.
I wonder whether the intention is to use the output to help improve the
quality of Microsoft’s search engine, Bing.
Anyhow, the so.cl interface is reminiscent of Google+ (especially party
invitations, that seem to... (more)

This post reviews the new Hyper-V 3.0 feature, Virtual Fibre Channel.

storage HBAs (host bus adaptors) installed in the Hyper-V server. Normally,
storage adaptors would be reserved for the use of the Hyper-V guest itself
however this new feature acts as a passthrough, enabl... (more)
At the end of August 2012, Amazon Web Services released their latest service
offering – a long-term archive service called Glacier. As a complement to
their existing active data access service S3, Glacier provides long term
storage for “cold” data – information that has to be retained for a
long time but doesn’t require frequent access.
What Exactly is Glacier?
Many organisations need to retain data in archive format for extended periods
of time. This is for regulatory or compliance purposes or may simply be
part of their normal business process. Good examples are medical,
