Setting bandwidth limitations
Bandwidth limitations are available to restrict the amount of network bandwidth used for Storage
Mirroring data transmissions. The network administrator specifies a percentage of bandwidth that is
available or an absolute bandwidth limit for Storage Mirroring transmissions and Storage Mirroring
never exceeds that allotted amount. The bandwidth not in use by Storage Mirroring is available for
all other network traffic. You can schedule when you want bandwidth limiting to occur.
1.
Right-click the connection on the right pane of the Management Console and select Connection
Manager.
2.
Select the Bandwidth tab.
3.
You have three bandwidth choices.
No Bandwidth Limit—Data will be transmitted at all times using all available bandwidth.
Fixed Bandwidth Limit—Data will be transmitted at all times according to the user-specified
bandwidth configuration.
Scheduled Bandwidth Limit—Data will be transmitted according to the user-specified
schedule and the user-specified bandwidth configuration.
4.
If you want to transmit data at all times using all of the available bandwidth, select No
Bandwidth Limit.
5.
If you want to transmit data at all times using limited bandwidth, select Fixed Bandwidth
Limit.
a.
By default, the Unlimited checkbox is enabled. This configuration is identical to selecting No
Bandwidth Limit. If you want to limit your bandwidth usage, clear this checkbox.
NOTE:
Any replication sets from a source connected to the same IP address on a target will share
the same bandwidth limitation configuration.
You will not be able to set a limit lower than 100% of a 28.8 Kbps connection speed. A
setting this low would cause abnormal behavior between Storage Mirroring servers
because of the lengthy delay between commands and responses transmitted between the
two servers.
You cannot set a bandwidth limit of zero (0). If you need to stop data transmission
completely, use the stop criteria on the Connection Manager Transmit tab.
