z Transmit data, regardless of snapshot size, after—(Default = 15 minutes) Enter a time value
and unit that will trigger a transmission from the source to the target. The minimum time allowed
is 5 minutes.
In the Target route area, enter the IP address on the target server to which you want to send data.
You can specify a limit for the bandwidth to be used by source-to-target communications for this
protection job. In the Bandwidth Limit area, select the Limit Bandwidth checkbox, then enter a
value (in kilobits per second) that bandwidth cannot exceed.
When you are finished, click Save.
NOTE: A snapshot transmission cycle from the source to the target will begin when either of the
threshold conditions are met: time or size. During the snapshot transmission cycle, the
thresholds are not monitored. After the snapshot transmission cycle has completed, the
application will again monitor these thresholds. If either of the thresholds were crossed
during the snapshot transmission cycle, then a new transmission cycle will begin
immediately.
You may need to adjust the data transmission frequency options to optimize performance
in your environment. Some factors you need to consider when adjusting these settings
include the volume of write traffic in the virtual machine, the allowed data loss time
period, and the cost to the virtual infrastructure.
NOTE: If your ESX 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 Select the target physical machine on page 17. This setting only applies to
SCP routing and is not applicable to Storage Mirroring for Virtual Infrastructure network
communications.
