Learn How VMware Virtualized Their Exchange 2007
VMware has released a white paper detailing how they successfully virtualized their Exchange 2007 environment. Achieving a 4:1 consolidation ratio, the entire virtualized Exchange environment consists of 40 Virtual Machines running on 10 ESX hosts. VMware was successfully able to utilize:
- VMware High Availability (HA)
- VMware Distributed Resource Scheduling (DRS)
- VMware vMotion
Special attention was payed to the storage subsystem to balance capacity versus performance.
The physical hardware utilized was the HP c7000 blade servers and EMC CXC3-80 storage.
Daily backups are done using traditional Exchange streaming backups to virtual tape libraries
One feature of their design is the use of two data centers to gain the advantage of physical diversity. The production environment also utilized the new Exchange Server replication technology Cluster Continuous Replication (CCR). The file share witness used by CCR to maintain quorum was housed in a third data center (not shown).
