Configuring N Port Virtualization

N Port virtualization (NPV) reduces the number of Fibre Channel domain IDs in SANs. Switches 
operating in the NPV mode do not join a fabric; rather, they pass traffic between NPV core switch links 
and end devices, which eliminates the domain IDs for these edge switches. 

NPV is supported by the following Cisco MDS 9000 switches only: 

  •

Cisco MDS 9124 Multilayer Fabric Switch

  •

Cisco MDS 9134 Fabric Switch

  •

Cisco Fabric Switch for HP c-Class BladeSystem

  •

Cisco Fabric Switch for IBM BladeCenter

Note

NPV is available on these switches only while in NPV mode; if in switch mode, NPV is not available.

This chapter includes the following sections:

  •

About NPV, page 13-1

  •

NPV Guidelines and Requirements, page 13-6

  •

Configuring NPV, page 13-7

  •

About NPV

Typically, Fibre Channel networks are deployed using a core-edge model with a large number of fabric 
switches connected to core devices. However, as the number of ports in the fabric increases, the number 
of switches deployed also increases, and you can end up with a dramatic increase in the number of 
domain IDs (the maximum number supported is 239). This challenge becomes even more difficult when 
additional blade chassis are deployed in Fibre Channel networks.

NPV addresses the increase in the number of domain IDs needed to deploy a large number of the ports 
by making a fabric or module switch appear as a host to the core Fibre Channel switch, and as a Fibre 
Channel switch to the servers in the fabric or blade switch. NPV aggregates multiple locally connected 
N ports into one or more external NP links, which shares the domain ID of the NPV core switch among 
multiple NPV switches (see 

Figure 13-1

). NPV also allows multiple devices to attach to the same port 

on the NPV core switch, thereby reducing the need for more ports on the core.
