shares Resource allocations for CPU (for
FSS PRM groups), private memory, and disk
bandwidth are specified in shares. A share is
a guaranteed minimum when the system is
at peak load. PRM allocates a percentage of
the system resource to each PRM group
based on its number of shares relative to the
sum of it and its siblings’ number of shares.
sibling group PRM group that shares a
parent group with one or more other PRM
groups. Resource shares are distributed
recursively to sets of sibling groups in a
hierarchy.

configuration and maintenance. This person
