Failover Control Center
From the Failover Control Center, you can manage, monitor, and control failover for your Storage
Mirroring servers. The Failover Control Center displays a main window for monitoring failover activity.
Control buttons to the right allow you to configure and manage your servers.
Configuring communication ports
The Failover Control Center use two ports for various Storage Mirroring communications.
 Service Transmit Port—The Failover Control Center uses this port to send commands to Storage
Mirroring servers.
 Heartbeat Listen Port—The Failover Control Center uses this port to listen for heartbeats
transmitted from Storage Mirroring servers.
To view or modify the port settings in the Failover Control Center, select Settings,
Communications.
Configuring refresh rate
The failover client periodically requests information from the source and target. Depending on the
type of information, the request may be a machine-specific request, like obtaining the Time to Fail
status from a target, or may be a general request, like determining which machines are running
Storage Mirroring.
The rate at which these requests are made can be modified through the Failover Control Center
refresh rate dialog box. Select
Settings, Refresh Rate. The default update interval is one second. A
lower refresh rate value updates the information in the Failover Control Center window's Monitored
Machines tree more often, but also generates more network traffic and higher utilization on the
client and target machines. A higher refresh rate value updates the information less frequently, but
minimizes the network traffic.
Clearing maintained security credentials
To remove cached credentials, access the credentials security option, by selecting Settings,
Security. To remove the security credentials, enable Clear Cached Security Credentials and then
click OK.
