Important performance issues

Take steps to prevent these issues which can affect FRS performance:

•Excessive traffic on the Ethernet LAN.

•Viruses that slow down network traffic.

•A firewall that slows traffic between the servers hosting FRS and the CV server. Any firewall must be open between these systems.

Important configuration notes

The following notes will help ensure a successful configuration:

•Production and recovery servers must be in the same Ethernet domain.

•Administrator privileges are required for all devices and software.

•No more than five databases per storage group and no more than four storage groups per Exchange instance are supported.

•All databases within a storage group must reside on one LUN of the HP disk array.

•The logs for each storage group must also reside on an HP disk array LUN, and the logs and the checkpoint file must be on the same LUN.

•The LUN that the databases reside on and the LUN that the logs reside on must NOT be the same LUN.
