Can SnapMirror impact on other workloads be reduced by throttling?
Applies to
ONTAP 9
Answer
- ONTAP 9 introduces a global SnapMirror throttling option configurable via the
options
command in cluster shell.- Example:
::> options -option-name replication*
::> options -option-name replication.throttle.enable <on|off>
::> options -option-name replication.throttle.incoming.max_kbs <KBps>
::> options -option-name replication.throttle.outgoing.max_kbs <KBps>
- The ONTAP 9 global throttle affects remote and local Type-DP and Type-XDP SnapMirrors.
- Changing global throttle takes effect immediately, while changing per-relationship throttle is reflected from the next transfer.
- Note: All replication throttles in ONTAP are in KiloBytes per second.
- If throttling isn't desired globally, this can also be done on a per-relationship basis.
