Hi folks, I want to ask a question about lun stats -o command, and what I can take from that output to incr
ease my performance on certain luns.
We have recently started to host exchange 2007 on our filers.
we are running a fas31xx series, in a cluster.
we have 2 exchange server at this point, one is on one head, and the other is on the other.
this is the output for one of my filers:
lun stats -o

by taking a look at this output, what can you suggest ?
Ive read about reallocate, and I ran it once before, to optimize large volumes and aggregates.
Anything else that I can do to optimize the system ?
Thank you!
