Why is Scalability Important?

The #1 reason IT managers deploy virtualization solutions is workload consolidation

�Put simply, the more workloads that can be encapsulated within VMs and combined onto a single server, the higher the consolidation ratio and greater the cost reduction

Partition Mobility: Active and Inactive LPARs

Active Partition Mobility

� Active Partition Migration is the actual movement of a running LPAR from one

physical machine to another without disrupting* the operation of the OS and

applications running in that LPAR.

� Applicability

� Workload consolidation (e.g. many to one)

� Workload balancing (e.g. move to larger system)

� Planned CEC outages for maintenance/upgrades

� Impending CEC outages (e.g. hardware warning received)

© 2010 IBM Corporation16

� Impending CEC outages (e.g. hardware warning received)

Inactive Partition Mobility

� Inactive Partition Migration transfers a partition that is logically ‘powered off’

(not running) from one system to another.
