In SLES 11, the priority scheduler uses virtual partitions to manage resources. The IWM system has no options for virtual partitions. A virtual partition is used to divide a system for a higher level of control over resource allocation and workload distribution. You can create virtual partitions and assign workloads to the partitions. A workload can be assigned to only one partition at a time. A maximum of 10 virtual partitions can exist.
- Virtual Partitions
- List of the partitions on a system and the workloads that are assigned to each partition. You can add and remove partitions and reassign workloads to other partitions.
- Partition Resources
- List of the resource allocation for each virtual partition in each planned environment. You can specify CPU and I/O fixed limits.
- Workload Distribution
- View of the resource distribution to workloads in each virtual partition in each planned environment. In SLG Tiers you can specify system hard limits, and for Tier 1 you can enable SLG expedite.
Assigning a workload to a different partition does not change the workload management method. Assigning an SLG Tier workload to a different partition does not change the workload tier assignment if both partitions have the same tiers. If the target partition does not have the same tiers as the source partition, then the workload is assigned to the lowest SLG tier in the target partition. For example, if a workload is moved from SLGTier3 in Virtual Partition A to Virtual Partition B, the workload is assigned to Tier3 in Virtual Partition B. If Tier3 does not exist in Virtual Partition B, then the workload is assigned to the lowest SLG Tier in Virtual Partition B.
