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.
