N_Port ID Virtualization (NPIV) N_Port ID Virtualization, or NPIV, is a Fibre Channel technology that allows multiple N_Port IDs to share a single physical N_Port. N_Port sharing allows multiple Fibre Channel initiators to utilize a single physical port, reducing hardware requirements in SAN design, especially where virtual SANs are used.

  • Page 27: Fibre Channel San Preparation

    This section describes, at a high level, how to prepare the Fibre Channel SAN for VMM2008 R2 NPIV SAN migration. After connecting the servers (adapter ports) and the storage array to the QLogic Fibre Channel switch, configure the switch so that the physical Fibre Channel adapters on both host servers have access to the same storage array.
  • Page 28 3-Fibre Channel SAN Preparation Virtual Host Bus Adapter Port Creation and SAN Zoning Alternatively, the SAN can be configured as two zones, with one host server and storage array in Zone 1 and the second host server and storage array in Zone 2. This configuration ensures that both host servers can see any LUNs presented (mapped) to them through the storage array.

    3-Fibre Channel SAN Preparation Host Presentation (Mapping) of Storage LUN The zoning configuration in Figure 3-2 shows two adapter ports: one virtual adapter port and one storage controller port in a single zone, for a total of four Fibre Channel ports. NOTE: As a best practice, place all servers in a single zone to ensure that the storage is visible across the entire SAN.
