Partitions

You can configure one or more cells as a partition to support an instance of an operating system or a virtual machine monitor. A partition is a logical computer in the system. You use partitions to run user applications that perform work to support your business.

Each cell in the system can support one partition. Systems with four cells can support one to four partitions. See the User's Guide for the partitioning rules.

Clustering

When several partitions are configured, the servers become a convenient platform for clustering. Because partitions (or cluster nodes, in this context) are neatly contained in the same cabinet, cabling requirements are simplified. Also, because cluster nodes are derived from the same pool of hardware components, you can quickly reallocate
