Thanks for the feedback Jim. That feature of the EQL is one of the reasons we're giving them serious thought for our VMWare environment.
It sounds like the latest version of FAST has some of the same capabilities. The previous versions required entire LUNs to be moved between storage tiers. I guess now it will move 1GB chunks at the block level, automagically of course. I'll post back if we end up getting to play with the features. - Sean On Wed, Oct 6, 2010 at 4:35 PM, Jim Holmgren <[email protected]> wrote: > We aren't using FAST on any of our CXs, but we'll soon be implementing > the equivalent on some of our Equallogic gear.
