Migrating Exchange 2010 To Dell Advanced Infrastructure Manager Environment

Availability Group (DAG). The DAG is an Exchange 2010-specific feature that allows clustering of
mailbox servers.
Figure 1 shows the logical view of the Exchange 2010 solution described in Table 2, without an AIM
environment. Two active directories can be used to provide immunity towards failure of one of the
domain controllers. Note that in the lab exercise, one machine was used for the domain controller.
Figure 1. Exchange 2010 logical topology
The multi-role Exchange servers and the domain controllers—eventually become part of the AIM
managed server pool. We added a standby server that acts as a backup server in case any operational
server fails. Thus in the AIM environment, we can have one domain controller. In case of its failure, the
domain controller will be retargeted to the standby server.
The AIM environment requires few more components as summarized in Table 3. The AIM controller runs
on a separate server and does not become part of any AIM managed server pool. Dell recommends that
the servers in the AIM managed pool belong to same family (same server generation) and satisfy the
networking requirements of the persona planned to run on them.
