The recommended configurations described in this paper provide server and storage sizing details to assist one in planning and budgeting for the Exchange 2010 hardware deployments. Details in this recommended configuration provides server and storage requirements to support 5,000 users with 256MB mailbox using the heavy usage profile. For this configuration all the Exchange server roles are deployed on virtual servers using Hyper-V R2. The virtualized environment consists of two Hub Transport (HT) servers, two Client Access Servers (CAS) and two mailbox servers. For increased availability the two mailbox servers are placed into Hyper-V failover cluster. The six virtual servers are hosted on four BL460c G6 server blades using two HP LeftHand P4500 IP based SAN storage nodes.
