96 IBM BladeCenter PS700, PS701, and PS702 Technical Overview and Introduction
System requirements for Active Memory Sharing
To use the Active Memory Sharing feature of IBM PowerVM, the following minimum system
requirements for Power7 processor based blade servers must be met:
Enterprise PowerVM Edition activation
Virtual I/O Server Version 2.1.3
IBM i 6.1.1 and IBM 7.1
AIX 6.1 TL 4
SUSE Linux Enterprise Server (SLES) 11 with SP1 or later

times.

3.3.7 N_Port ID Virtualization (NPIV)
N_Port ID Virtualization (NPIV) is a technology that allows multiple logical partitions to access
independent physical storage through the same physical Fibre Channel adapter. NPIV
provides direct access to Fibre Channel adapters from multiple client partitions, simplifying
the Fibre Channel SAN environment. This adapter is attached to a VIOS partition, which acts
only as a pass-through managing the data transfer through the POWER Hypervisor.
Each partition using NPIV is identified by a pair of unique worldwide port names, enabling you
to connect each partition to independent physical storage on a SAN. Unlike virtual SCSI, only
the client partitions see the disk.
Note: Active Memory Expansion is not supported on POWER7 processor-based blade
servers.
