The SLES 11 priority scheduler implements priorities and assigns resources to workloads based on a tree structure. The priority administrator defines workloads in Viewpoint Workload Designer and places the workloads on one of several different available levels in this hierarchy. On some levels the admin assigns an allocation percent to the workloads, on other levels not.
How does the administrator influence who gets what? How does tier level and the presence of other workloads are on the same tier impact what resources are actually allocated? What happens when some workloads are idle and others are not?
This posting gives you a simple explanation of how resources are shared in SLES 11 priority scheduler and what happens when one or more workloads are unable to consume what they have been allocated.
