The workload will be generated by a gaggle of virtual machines, most of which I
expect to be running the normal mix of Microsoft/Office type applications (of
which I expect MS-Exchange to be the most demanding).
I gather the LSI card allows you to dedicate the entire NVRAM cache to writes

I have been tasked with putting together a storage solution for use in a
virtualization setup, serving NFS, CIFS, and iSCSI, over GigE. I've inherited a
few components to work with:
x86 dual core server , 512MB LSI-ELP RAID card
12 x 300GB 15Krpm SAS disks & array
