In SLES 11, you can configure a virtual partition by allocating resources to workloads in the partition. Resources can be allocated differently for each planned environment. The resource consumption may differ from the allocation you set, based on activity on the system. Resources are allocated to management methods as follows:

Tactical
Tactical workloads have access to all available resources. A tactical exception is automatically created when you create a tactical workload in SLES 11.
SLG Tier
SLG Tier workloads have access to remaining resources after tactical demands are met. If multiple SLG Tiers exist, resources are allocated first to Tier 1, with workloads in each tier consuming resources and passing remaining resources down to the next tier.

A workload that is moved into a fully allocated tier receives minimal tier resources (5%). The resources are taken from the workload with the highest allocation in the tier.

Timeshare
Timeshare workloads have access to remaining resources after tactical and SLG resource demands are met.
  • Top queries are given an access rate eight times the Low access level.
  • High queries are given an access rate four times the Low access level.
  • Medium queries are given an access rate two times the Low access level.
  • Low queries are given the lowest access rate for the Timeshare method.
