b. To limit the bandwidth usage, enter the maximum amount of data you want to transfer per
second. You can indicate it by specifying your Connection Speed and the Percentage of
the bandwidth that you want to use or by entering the Transfer Rate value directly.
6. If you want to transmit data according to a schedule using limited bandwidth, select Scheduled
Bandwidth Limit.
a. Click New Event to create a bandwidth schedule event.
1. Specify a name for the bandwidth schedule event.
2. Select the day(s) of the week that you want this event to be iniitated on.
3. Specify the time when you want this event to start.
4. Specify the bandwidth limitation. By default, the Unlimited checkbox is enabled. This
setting will not limit the transfer of Storage Mirroring data during the day and time
specified. If you want to limit your bandwidth usage, clear this checkbox. To limit the
bandwidth usage during the day and time specified, specify the maximum amount of data
that you want to transfer per second. You can indicate it by specifying your Connection
Speed and the Percentage of the bandwidth that you want to use or by entering the
Transfer Rate value directly.
b. Repeat each part of the new event creation to establish a comprehensive bandwidth
schedule. For example, if you want to limit Storage Mirroring bandwidth usage weekdays
(Monday - Friday) from 6:00 a.m. to 8:00 p.m. and have unlimited bandwidth usage outside
of those times, you would create two events. The first event would be for Monday through
Friday, would start at 6:00 a.m., and would limit the bandwidth to the desired rate. The
second event would be Monday through Friday, would start at 8:00 p.m., and would not limit
the bandwidth. (The Unlimited checkbox would be enabled.) In this schedule, on Monday at
6:00 a.m., the schedule limit would be applied, limiting the transfer of data. At 8:00 p.m.
that night, the schedule limit would be applied again, unlimiting the transfer of data. At 6:00
a.m. Tuesday morning, the schedule would be applied again. This would continue until the
Friday 8:00 p.m. schedule is applied. That event would remain in effect until Monday
morning at 6:00 a.m.
c. Hightlight an existing schedule event and click Edit Event to make modifications to the
event. The same steps used to create the event can be used to edit the event.
d. Hightlight an existing schedule event and click Remove Event to delete the event that is no
longer needed.
e. You can export the entire schedule for use on another Storage Mirroring server by clicking
Export Schedule. Specify a file name and location, and an XML file with the schedule
information will be saved.
f. You can import an exported schedule by clicking Import Schedule. Locate the XML file and
click OK. Any existing schedule will be overwritten by the imported schedule.
7. Click OK to save the settings.
NOTE: You can establish a bandwidth schedule and then disable or override it by selecting No
Bandwidth Limit or Fixed Bandwidth Limit. The schedule criteria will be saved and
will not be reactivated until you reselect Scheduled Bandwidth Limit.
You can modify the bandwidth limits applied to a connection that is already established
by right-clicking on the connection and selecting Set Bandwidth. A modified version of
the Connection Manager Bandwidth tab will allow you to select a different bandwidth
limitation. You cannot create a schedule from this dialog box. An existing schedule must
already exist in the Connection Manager.
