Setting a maximum transfer rate for all transfers enables you to limit the total bandwidth used by all transfers at any time. To set a maximum transfer rate for all transfers, Data ONTAP allows you to set a maximum rate for transfers coming into a storage system and to set a maximum rate for transfers going out of a storage system.
Considerations
Note: This applies to all
SnapMirror and
SnapVault transfers.
You can configure a maximum transfer rate for a
storage system and set maximum transfer rates for each transfer using the
/etc/snapmirror.conf file. When system-level transfer rates and transfer-level transfer rates are configured, the system-level maximum rate is applied only if the combined bandwidth of all incoming and outgoing transfers goes above the system-level maximum rate.
Steps
- Enable the ability to set system-level maximum transfer rates using the following command:options replication.throttle.enable on
- If you are specifying the maximum transfer rate used by transfers coming into a storage system (applied at the destination system), enter the following command:options replication.throttle.incoming.max_kbs value
value is the maximum transfer rate in kilobytes per second. Valid transfer rate values are 1 to 125000. The default value is unlimited.
- If you are specifying the maximum transfer rate used by transfers going out of a storage system (applied at the source system), enter the following command:options replication.throttle.outgoing.max_kbs value
value is the maximum transfer rate in kilobytes per second. Valid transfer rate values are 1 to 125000. The default value is unlimited.
After You Finish
