what version of EV and what type of storage (make, model, disks, etc) will you be using? it is strongly recommended to work with a partner as opposed to trying to design your own EV environment.

EV v11 will be used for Exchange archiving on NetApp storage (OnTAP 8.2.x 7-Mode). Index files, msmq and etc. will be located on fast disks, vault stores on slow SATA drives.

I spoke with Symantec and they've advised that 4K for Index locations and 64K for Vault stores is good enough.
