24 Protecting an Exchange Server
NOTE: In a cluster environment, make sure to include a “cushion” to account for the time it takes for the
cluster to failover.
• Monitor Interval (sec) — (Default = 5) How often the monitor checks the source machine availability.
• Missed Packets (sec) — (Default = 5) How many monitor replies can be missed before assuming the source
machine has failed.
Failover trigger
If you are monitoring multiple IP addresses, select one of the failover trigger options:
• All Monitored IP Addresses Fail —Failover begins when all monitored IP addresses fail.
• One Monitored IP Address Fails —Failover begins when any of the monitored IP addresses fail.
Manual intervention required
(Default = selected) Manual intervention allows you to control when failover occurs. When a failure occurs, a
prompt appears and waits for you to initiate the failover process manually.
Disable
Manual Intervention Required only if you want failover to occur immediately when a failure condition is
met.
Connection settings
The Connection tab includes options that will be applied to the specified source/target connection.
Route
This setting identifies the Target IP Address that the Storage Mirroring data will be transmitted through. You
should only change this setting if you want to select a different route for Storage Mirroring traffic. On a
machine with more than one NIC, this increases the flexibility of configuring Storage Mirroring activity. For
example, you can separate regular network traffic and Storage Mirroring traffic on a machine. The default
ports will be used.
