The IBM System z9 and its predecessors pioneered server virtualization, including the sharing of data storage subsystems among the virtual servers of a host computer using the channel-sharing capabilities of FICON channels in Fibre Channel (FC) fabrics. Now industry-standard Small Computer System Interface (SCSI) devices in storage area networks must be shared among host computers using the Fibre Channel Protocol (FCP), and this has been problematic with virtual servers in a host computer. To apply the power of server virtualization to this environment, the IBM System z9 implements a new FC standard called N_Port Identifier Virtualization (NPIV). IBM invented NPIV and offered it as a standard to enable the sharing of host adapters in IBM servers and FC fabrics.
