Learn about the advanced features of the PowerVM® hardware
feature, such as shared storage pools, Micro-Partitioning® technology, Live Partition Mobility, PowerVM Active Memory™ Sharing, Active Memory Deduplication, and Capacity on Demand.
Shared storage pools
On the Virtual I/O Server (VIOS) Version 2.2.0.11,
Fix Pack 24, Service Pack 1, and later, you can create shared storage pools. Shared storage pools provide distributed
storage access to all VIOS logical
partitions in a cluster.
PowerVM Active Memory Sharing
The PowerVM Active Memory Sharing technology
enables selected logical partitions to share memory from a single
pool of physical memory. A new level of abstraction managed by the
hypervisor supports the Active Memory Sharing technology. The Active Memory Sharing technology is
available with the PowerVM Enterprise Edition for
which you must obtain and enter an PowerVM Editions activation
code.
Active Memory Deduplication
Active Memory Deduplication
is a feature that is available on systems that have the PowerVM Active Memory Sharing technology. PowerVM Active Memory Sharing is
available with the PowerVM Enterprise Edition hardware
feature. Active Memory Deduplication is
a virtualization technology in which memory pages with identical contents
are coalesced (or deduplicated) in physical memory. Active Memory Deduplication aggregates
the same data in one memory position, and frees other duplicate memory
blocks, thus optimizing memory use.
