Enterprise Computing: Why Thin Provisioning Is Not The Holy Grail for Utilisation

Thin Provisioning (Dynamic Provisioning, Virtual Provisioning, or whatever you prefer to call it) is being heavily touted as a method of reducing storage costs.  Whilst at the outset it seems to provide some significant storage savings, it isn’t the answer for all our storage ills.   What is...

Review: OCZ SSD – Solid State Disk

We’re all aware of how solid state disks are becoming mainstream storage devices. Vendors are adding SSDs to arrays and to servers in order to increase levels of performance. I’ve been curious to understand how an SSD performs relative to traditional disk devices so I’ve purchased...

Testing Out IT Principles – With Children

I was driving my youngest son back from Beavers this evening and we were talking computers and games (he’s 6). He reminded me that some of his games won’t run on Vista which is why I’d installed dual booted XP on the kid’s machine. He asked me if I’d played “Age...

Pillar Crumbles

I picked this up last night on Mike Workman’s blog over at Pillar. Looks like they’re suffering the downturn. Storagezilla thinks this could be 30% of the workforce. I’m sure this is going to be one of many bad news stories from the storage industry we hear over the next few months. I’ve...

Hitachi and Hardware II

After my last post I think I should have been a little more specific. Whist I’m aware HDS is owned by Hitachi, I pointed out that HDS is effectively a reseller for their hardware. In my experience, HDS take the hardware as Hitachi deliver/design it. I’ve not seen a huge feedback loop...

No Datacentres in Leicester?

I read something today that quoted BroadGroup’s 2006 Power and Cooling Survey. It states that the average UK datacentre uses more power in one year than the city of Leicester. Now, surely that means there can’t even be one average size datacentre in Leicester, or no-one else in the City...

Recyclable Storage

I’ve just had the details through of our new recycling “rules” at home. I now have *four* bins; one for bottles, one for green/garden waste, one for recyclables (plastic bottles, paper, etc) and one for remaining rubbish. Theoretically you’d think that there would be almost...

Performance – Part II

Next on the performance list – Sidefile. Sidefile is only relevant if you are using asynchronous replication. Cache is used to store write I/O requests (which have been committed locally) until they have been confirmed by a remote array in a TrueCopy pair. Both the local and remote arrays use...
