There has been so much discussion in the past 2 weeks over Hitachi Dynamic Provisioning (HDP) and the size of our pages which are, by comparison, large when compared to other thin provisioning implementations. As we all recall from our first course in Computing 101 and memory management, larges pages in memory provide better performance [...]

I ran across this today on Slashdot and Network World.

I recently ran across this post on Storagezilla.  Well I have to say after having looked at their approach to file tiering I have to say nice try.  As I’ve talked about in the past I was there when an external Acopia (now a product of F5) reference customer basically stated they would throw out [...]

What is Innovation?

Since I’ve been talking about commodity versus novel implementations as well as innovation of late something recently caught my eye.  Notably a purist debate on how Fedora will no longer include the TomBoy application and folks are equally skeptical about Mono.
