Setting a maximum transfer rate for all transfers enables you to limit the total bandwidth used by all transfers at any time. You can set a maximum rate for transfers coming into a system, and a maximum rate for transfers going out of a system.
About this task
You can configure a maximum transfer rate for a system and set maximum transfer rates for each transfer using the
/etc/snapmirror.conf file. When both the rates are configured, the system-level maximum transfer rate is applied only if the combined bandwidth of transfers goes above the system-level maximum rate. This setting applies to all SnapMirror and SnapVault transfers.
Note: If the SnapMirror relationships exist within the same system, you must set the snapmirror.volume.local_nwk_bypass.enable option to off to enable throttling of the SnapMirror transfers.
