HP Integrity VM 4.3 N-Port ID Virtualization - A brief overview

Figure 1. NPIV Presentation (two VMs, both with vHBAs)

Here, the host has a single physical Fibre Channel HBA with p-WWN as its WWN. Assume the LUNs D1-D6 exist

behind this physical Fibre Channel HBA. Using the NPIV feature, two virtual Fibre Channel ports with WWNs v-WWN1

and v-WWN2 are created and assigned to VMs V1 and V2 respectively.

Using zoning on the Fibre Channel switch and/or LUN masking on the storage device, the LUNs D1 to D6 behind the

physical Fibre Channel HBA can be selectively presented to the VMs and the host. In this case, V1 has access to

LUNs D3 and D4 while V2 has access to LUNs D5 and D6. LUNs D1 and D2 are accessible to the host as well as

both of the VMs.
