Get the Balance Right

It’s not very often I side with one vendor or another however after BarryB’s recent post regarding “Benchmarketing” I feel obliged to comment. Have a read of Barry Whyte’s rebuttal too. We see technology advancements because “concept” devices are used to drive innovation but don’t necessarily translate directly to end-user products. Look at the fashion industry – some of the ...

Who Ya Gonna Call?

Here’s a quality piece of reporting from TechCrunch on the state of Facebook and their data problems. I mentioned just last week in this post about their data growth.

Disk groups are ... Read More »

Virtualisation: LeftHand VSA Appliance – Part Two

In my previous post covering LeftHand’s Virtual Storage Appliance, I discussed deploying a VSA guest under VMware. This post discusses performance of the VSA itself. Deciding how to measure a virtual storage appliance’s performance wasn’t particularly difficult. VMware provides performance monitoring through the Virtual Infrastructure Client and gives some nice pretty graphs to work with. So from the appliance (called ... Read More »
