3.4.8 N_Port ID virtualization
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. This adapter
is attached to a Virtual I/O Server partition that 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.
For additional information and requirements for NPIV, see these resources:
򐂰 PowerVM Migration from Physical to Virtual Storage, SG24-7825
򐂰 IBM PowerVM Virtualization Managing and Monitoring, SG24-7590
NPIV is supported in PowerVM Standard and Enterprise Editions on the IBM Power 770 and
Power 780 servers.
