Highly available data center design
The solution is designed around a highly available data center model (Figure 1). There are two disk arrays for
complete redundancy. The Exchange configuration is one DAG. There are two networks for redundancy for
both front-end and iSCSI traffic.
The tested portion of the solution was a single ME4024 array running a workload with 8,000 concurrent users.
This demonstrates the ME4024 array can easily handle the full workload of all users in a failover scenario. In
the normal state, half of the users access mailboxes from each array.
The testing shows that no users would be impacted in a failover scenario. This also allows maintenance for
half of the environment without user impact.
