HP StoreOnce Backup - Manual (Page 59)

IMPORTANT: If replication takes place through a firewall, the network administrator must open
(TCP) ports 9387 (Command protocol) and 9388 (Data protocol) to allow the replication traffic
to pass to and from the HP StoreOnce Backup systems.
Bandwidth Limiting tab
This tab allows users with an Admin login to apply a general bandwidth setting and configure
bandwidth limiting windows.
Bandwidth limiting can be used to avoid saturating the WAN with low bandwidth replication to
free up bandwidth for other processes and applications. A minimum of 2Mb/s per concurrent job
is recommended. At least 512Kbps per concurrent job is required for reliable operation. These
limits apply to all outbound replication jobs from this local appliance.
1.
Display the Bandwidth Limiting tab.
2. Check the General Limit Enabled box. Determine the recommended general bandwidth limit,
which is a simple calculation of:
(Max WAN Speed) x (Max Desired WAN Usage%).
A Bandwidth Limit Calculator is provided on this tab to work out limit values.
3. Click Edit to edit the Bandwidth Limiting Windows.
Configure up to two windows for each day. Use the spinners to select the Start Of Restriction
and End Of Restriction times. Enter the appropriate Bandwidth Limit in each required window.
(If you use the Bandwidth Limit Calculator, enter the value from the Recommended Limit field.)
Check the appropriate Apply First/Second Restriction check boxes. This ensures the specified
times are enabled. If it is not checked, the times are ignored.
NOTE: All settings are applied to the HP StoreOnce Backup system, not for individual jobs.
The Bandwidth Limit windows override the General Limit when the time specified for the
window is active. Outside of Bandwidth Limit windows the General Limit applies.
