Viewing A List Of Remote Snapshots; Setting The Remote Bandwidth; Selecting Remote Bandwidth Rate; Best Practice - HP StorageWorks P4000 User Manual

Viewing a list of remote snapshots

View a list of remote snapshots associated with management groups, clusters, volumes, or snapshots.
1. In the navigation window, select a cluster to view its list of remote snapshots.
2. Click the Remote Snapshot.
The report in the Remote Snapshot tab lists management groups and all the snapshots. The other
columns show status information about the remote snapshots. For more information, see
"Monitoring remote

Setting the remote bandwidth

The remote bandwidth sets the maximum rate for data transfer between management groups. The
copy rate is equal to, or less than, the rate set.
To control the maximum rate of data transfer to a remote snapshot, set the remote bandwidth on the
management group that contains the remote snapshot which is the remote management group. When
setting the remote bandwidth, you can choose from a list of common network types, or calculate a
custom rate, based on your particular requirements.

Selecting remote bandwidth rate

You may either select a preset speed from a list of standard network types or calculate a custom speed
based on your specific requirements. Remember that the speed is the maximum rate at which data
copies.
Defaults setting
When setting remote bandwidth, selecting Defaults allows you to choose from a list of common network
types.
Custom setting
The custom setting for remote bandwidth defaults to 32,768 KB, or about 4 MB. Use the calculation
tool to identify a desired bandwidth setting. For example, if you have a T1 line and you want to set
the remote bandwidth to 12% of that capacity, you can use the calculation tool to find the correct
value, 189 KB.

Best practice

Set the bandwidth speed the same in both directions unless you have an asymmetrical WAN link.
