Network
The Network tab contains settings that control network communications. Any changes made to this tab will not take effect
until the Storage Mirroring service has been restarted on the server.
 Default Address—On a machine with multiple NICs, you can specify which address Storage Mirroring traffic will use.
It can also be used on machines with multiple IP addresses on a single NIC.
 Default Protocol—The default protocol for all Storage Mirroring communications is the TCP/IP protocol. In the future,
Storage Mirroring may support other communication protocols.
 Service Listen Port—Storage Mirroring servers use the Service Listen Port to send and receive commands and
operations between two Storage Mirroring servers.
 Heartbeat Transmit Port—A Storage Mirroring server sends its heartbeats to the Heartbeat Transmit Port.
 Status Listen Port—Storage Mirroring servers use the Status Listen Port to listen for requests from the Management
Console and other clients.
 Time Between Heartbeats—All Storage Mirroring servers transmit a heartbeat. This heartbeat allows other Storage
Mirroring servers and Storage Mirroring clients to locate and identify the Storage Mirroring servers. The heartbeat is a
broadcast UDP transmission. This heartbeat can be disabled, but if it is, Storage Mirroring will not auto-detect the Storage
Mirroring servers to populate the Management Console. By default, there are
3 seconds between heartbeats. If you set
this option to
0, the heartbeats are disabled.
 Missed Heartbeat Limit—This is the number of heartbeats which can be missed before transmission is stopped and
data is queued on the source.
