If you want to use supercache or uptempo the idea is that you take AWAY from windows/SQL/exchange cache and add to the fancy cache.
On deduplication and Data Domain appliances
One subject I keep hearing about is deduplication. The idea being that you save a ton of space since a lot of your computers have identical data.
One way to do it is with an appliance-based solution such as Data Domain. Effectively, they put a little server and a cheap-but-not-cheerful, non-expandable 6TB RAID together, then charge a lot for it, claiming it can hold 90TB or whatever. Use many of them to scale.

So who am I?
Hello everyone,
My name is Dimitris Krekoukias.
This blog used to be on another server, I moved it here – hopefully this hosting facility will be more stable.
I resemble a silverback gorila more than a monkey (man-pelt and all), and could probably wrestle one (and have a fair chance of winning).
I have extensive experience in the storage, performance, backup and recovery arena, and indeed know far more about certain products than I (or, indeed, the respective vendors) would like to.
Hopefully everyone will find this blog stimulating, controversial and, at times, annoying – in which case, tough.
