System Partitioning

System Partitioning

Single Domain

•Cannot be partitioned.

•A single-domain system contains:

−Its own power, cooling, and maintenance interface

−Its own master clock

Dual Domain

Single Monolithic Partition

•The combined domains function as a monolithic system.

•Each domain contains a separate power subsystem and maintenance interface.

•Cooling is shared between domains.

•Although each domain contains a master clock, only one master clock is used by the partition.

Two Separate Partitions

•Each partition functions as an independent system.

•The partitions cannot share resources.

•Each partition must include at least one PM, one IOM, and one MSU.

•Each domain contains a separate power subsystem and shared cooling, regardless of the division of resources among partitions.

•Each partition uses a separate master clock and has a separate maintenance interface, regardless of the division of resources among domains.
