Bandwidth Limiting Tab; Blackout Windows Tab - HPE StoreOnce 6500 User Manual

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 StoreOnce System.

Bandwidth Limiting tab

This tab allows users with an administrator 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.
Procedure
1. Click the Bandwidth Limiting tab.
2. In the General Bandwidth Limit section, check the General Limit Enabled box.
3. Determine the recommended general bandwidth limit, which is a simple calculation of:
(Max WAN Speed) x (Max Desired WAN Usage%).
4. Use the Bandwidth Limit Calculator on this tab to work out limit values. Set the desired WAN speed
and Desired Maximum WAN usage, and the Recommended Bandwidth Limit field will show the
desired bandwidth value.
5. In the General Bandwidth Limit section, click Edit. Enter the value calculated in the Bandwidth
Limit Calculator in the General Bandwidth Limit field.
6. Click Edit.
7. 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.)
NOTE: Start and End of Restriction times are set and displayed in UTC regardless of the selected
local time zone so adjust accordingly. For example, U.S. CDT (Central Daylight Time) is five hours
behind UTC. If you are in CDT and want a start time of 6:00 p.m., set the start time to 23:00 (instead of
18:00).
8. 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 StoreOnce 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.
9. Click Apply.

Blackout Windows tab

This option allows users with an administrator login to specify times when replication will not occur, for
example during planned maintenance or heavy network traffic. You can configure multiple blackout
windows.
