Hi all,

a couple of time I've experienced some performances issues with Exchange 2010 installed on "luns" on a NetApp filer. Worst cases of course when I've some secondary passive DAG setup on SATA aggregates. I've almost read everything about best practice both on VMware FC SAN storage and Exchange natively setup on FC LUNs; there's also a very interesting TR about E2K10 on 2240 FAS with SATA only!

But there's something not clear. In this environment: Storage NetApp vSphere 5.1 E2K10 Vdisk diretti (non rdm) Datastore FCP

Which are the parameters you consider to best optimize everything? The VMware ones? The Exchange ones? A mean between the two? :) I.e are read_realloc or extent options really useful?

Regards,
