Source and destination servers in a partition mobility environment

Two servers are involved in partition mobility that is managed by the Integrated Virtualization Manager (IVM). The source server is the server from which you want to move the logical partition, and the destination server is the server to which you want to move the logical partition.

The source and destination servers must be POWER6® processor-based servers, or later, to participate in partition mobility. The destination server must have enough available processor and memory resources to allow the mobile partition to run on its server.

Shared memory is physical memory that is assigned to the shared memory pool and shared among multiple logical partitions. The shared memory pool is a defined collection of physical memory blocks that are managed as a single memory pool by the hypervisor. Logical partitions that you assign to the shared memory pool share the memory in the pool with other logical partitions that you assign to the pool.

If the mobile partition uses shared memory on the source server, the destination server must also have a shared memory pool to which the mobile partition can be assigned. If the mobile partition uses dedicated memory on the source server, it must also use dedicated memory on the destination server.
