Hi there! Today I’d like talk a little bit about the latest technology in the virtualization area – NPIV. NPIV is an acronym for N Port ID Virtualization. N_Port ID Virtualization is a Fibre Channel (FC) industry standard technology that provides the capability to take a physical Fibre Channel Host Bus Adapter (HBA) port and assign it multiple unique world wide port names (WWPNs). The world wide port names can then be assigned to multiple initiators such as Operating Systems. Thus, NPIV allows physical N_Port to be logically partitioned into multiple logical ports/FC addresses so that a physical HBA can support multiple initiators, each with a unique N_Port ID.
Since NPIV provides a direct access to Fiber Channel adapters from multiple client partitions, it simplifies SAN management. Various SAN management tools and best practices can be applied. For example, LUN mapping/masking, fabric zoning and fabric based QoS and accounting can be employed. With NPIV, multiple client partitions can share a bunch of adapters, yet have independent access to their own storage devices. This results in the most efficient adapter utilization.
NPIV is now supported on selected POWER6 processor-based servers and is included as part of PowerVM Express, Standard, and Enterprise Edition. For more information, checkout the following website:https://www14.software.ibm.com/webapp/set2/sas/f/vios/documentation/home.html
AIX Developers will discuss the latest in AIX technologies.
