1.2 System partitioning
Partitioning is the ability to divide a system to support multiple operating system images simultaneously. The benefits of system partitioning include:
Hardware consolidation
Software migration and coexistence
Version control
Development, testing and maintenance
Workload isolation
Resource optimization around a particular application and operating system combination
Independent backup and recovery on a partition basis
There are two types of system partitioning: physical partitioning
Logical partitioning
Using logical partitioning, administrators can partition a multinode complex at the individual processor level (with associated memory, I/O and other required resources) or even lower (that is, multiple partitions per processor) without shutting down and restarting the hardware and software.
VMware ESX Server V1.5 supports one to eight partitions per CPU, up to a maximum total of 64 partitions. For example, in an
ESX Server virtualizes the resources of the x440 and is the closest that
When workload demands change, you can reassign resources from one logical partition to another without having to shut down and restart the system. ESX Server does not, however, support

Physical partitioning
This form of partitioning is available in 4Q 2002 with the release of System Partition Manager, a
