NDMP Throttler is introduced in OneFS 8.2.0 and is disabled by default. NDMP Throttler is global to all nodes in the PowerScale cluster and manages CPU usages of both NDMP two-way and three-way sessions. NDMP throttler ensures that NDMP operations do not compete with things that are performance sensitive like SMB and NFS user activity. You only can enable NDMP Throttler by command-line interface.
Run the following commands through the command-line interface to enable NDMP Throttler, and set the throttler CPU threshold value in percent:
# isi ndmp settings global modify --enable-throttler true
# isi ndmp settings global modify --throttler-cpu-threshold=<value-in-percent>
