Re: Just a big EVA LUN or many smaller EVA LUNs ?

This issue with EVA's is not the LUN size, but the size of the Disk Group. The EVA gets its best performace when you have 1 or 2 disk groups. I/O is spread out over more spindles, more spendles = more I/O capability. So you could have a 500GB LUN or 70GB LUN on an EVA and theoritically they would have the same spindle to GB ratio.

I know there USED to be such assumptions...

fwiw

Proost.

Have one on me.
