Tuning bandwidth and throttling options

Use this procedure to configure how your replicating systems use the available bandwidth. This procedure can be run from the source or target system.

To tune bandwidth and throttling options

1 Log in to the source or target system.
2 Select the source system in the Navigation Pane, and then select Replication > Replication Attributes.
3 In the Bandwidth and Throttling Options section, configure the following:
Connection Type – The connection’s theoretical physical bandwidth. If your specific connection is not in the list, pick the closest upstream bandwidth match.
Connection Effective Bandwidth – What you expect the actual bandwidth of the physical connection to be.
Throttling Settings – Use the grid to configure settings.

Throttling is simply the act of responsibly sharing the bandwidth of the WAN by which the Unitrends target provides replication and disaster recovery services. Set the weekly replication schedule using the graphical tool consisting of 7x24 small boxes that represent each hour of the week.

Multiple throttling scenarios can be configured. Select the throttle percentage, then click and drag the mouse pointer to highlight the days and times to use the selected percentage. Perform this step as many times as needed to fully configure throttling scenarios. The percentage you select uses X percent of the Connection Effective Bandwidth you set above for replication.

Note:  Throttling is enforced in one-second intervals. There could be spikes in bandwidth consumed within a fraction of a second causing utilization to exceed the level you set here.
