A customer is deploying an Exchange 2010 environment on an EMC VNX. There will be 30,000 mailboxes distributed across mailbox servers within a DAG (database availability group) that maintains three database copies. Each user sends approximately 350 messages per day. The customer wants to use 600 GB 15K drives in a RAID 5 group.
How many spindles are needed to support the performance required for this Exchange environment?
