Note:
If your host is on multiple networks and has multiple addresses associated with
those networks, you can choose to use an IP address other than the one you
entered for the target in Selecting a target server.
2. Compression—Select the compression level (None, Low, Medium, or High) to
use when sending data from the source to target server.
3. Limit Bandwidth—You can specify a limit for the bandwidth to be used by source-
to-target communications for this protection job. Select the Limit Bandwidth
checkbox, then enter a value (in kilobits per second) that bandwidth cannot
exceed.
4. Fail over automatically if the target server cannot contact the source server—
If you want the target server to stand in for the source server when the source is
inaccessible, select this checkbox.
Note:
● The automatic failover option is only available if the source virtual
machine is running and integration services are installed on it.
● Automatic failover will occur if either the physical host or source
virtual machine goes down.
● Automatic failover will not occur until after the initial mirror has
completed. If the source virtual machine goes down while the initial
mirror is in process, the failover will not occur until the mirror is
completed because some files needed for failover may not yet be
synched to the target.
● Stopping the Storage Mirroring service on the source will not affect
failover. The failover monitor will continue running even if the
Storage Mirroring service is stopped. Automatic failover will not
occur until Storage Mirroring comes back up on the source.
5. Monitoring interval (seconds)—(Default = 5) Select how often the monitor will
check the source machine availability.
6. Number of missed intervals that trigger failover—(Default = 5) Select how many
monitor replies can be missed before assuming the source machine has failed.
7. When you have finished setting protection options, click Next. The Protection
Summary window will appear.
