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.
