[1] Live Partition Mobility, a component of the PowerVM Enterprise Edition hardware feature, provides the ability to move AIX, IBM i, and Linux logical partitions from one system to another.
The mobility process transfers the system environment that includes the processor state, memory, attached virtual devices, and connected users.
The source and target systems must have access to the same network and SANs but need not be of the same type, the only requirement is they use POWER6, POWER7, or POWER8 processors.
When a threshold is reached (i.e. when a high percentage of the pages have been successfully copied across), the partition is transitioned to the target machine and any remaining pages are copied across synchronously.
The agents which carry out the memory copying are nominated Virtual I/O Servers on each machine; a standard Ethernet network is used for data transmission.
