Configuring advanced functions with VMware

N_Port ID Virtualization (NPIV) is an extension to the FC industry standard. In a server virtualization environment, NPIV allows each VM to have a unique FC World Wide Name (WWN).

When each VM has a unique FC WWN, multiple VMs can then share a single physical host bus adapter (HBA) and switch port.

Note: NPIV is an optional advanced feature.

NPIV implementation requirements
To enable NPIV, ensure that the following hardware and software requirements are met.
Server administrator tasks
While you configure NPIV, you can complete the server administrator tasks.
Storage administrator tasks
Complete the following storage administrator tasks to configure NPIV.
Verifying the NPIV configuration
When you configure NPIV and turn on the VM, the NPIV is functioning. To verify that I/O traffic is going through the virtual port (depending on the host HBA), you must create a Secure Shell connection to the physical VMware ESX(i) Server.
Snapshot principles when NPIV is used
The IBM Storage Support for Microsoft VSS and VDS automatically detects whether the NPIV is enabled. If the NPIV is enabled and functioning correctly, the IBM Storage Support for Microsoft VSS and VDS takes the appropriate actions during the various snapshot stages.
