Process Resource Manager (PRM) Disk
Bandwidth Control
This release allows Process Resource Manager (PRM) to report and
control disk I/O bandwidth per LVM device. Based on user configured
priorities, PRM will reorder LVM disk queues to enforce the percentage
of disk bandwidth a PRM group receives in an I/O-constrained
environment. The functionality is documented in the PRM manpages.
