Network
The
Network
tab contains settings that control network communications. Any changes made to this
tab will not take effect until the Storage Mirroring daemon 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.
Show Heartbeat Messages in Logger—This checkbox enables the heartbeat messages in the
Storage Mirroring log. Enabling this option will cause your logs to fill up faster.
