In this paper, a large installation of 16,000 Exchange users was configured across eight virtual machines (VMs) on a single VMware vSphere„¢ 4 server. The performance of this configuration was measured when using storage supporting Fibre Channel, iSCSI, and NFS storage protocols. The results show that each protocol achieved great performance with Fibre Channel leading the way, with iSCSI and NFS following closely behind.
