Virtual Fabrics requirements

To configure Virtual Fabrics, you must have at least one Virtual Fabrics-enabled physical chassis

running Fabric OS 6.2.0 or later in your SAN. Use one of the following options to discover a Virtual

Fabrics-enabled physical chassis on the Management application topology:

• Discover a Virtual Fabrics-capable seed physical chassis running Fabric OS 6.2.0 or later.

Virtual Fabrics is disabled by default. This physical chassis displays as a legacy switch. Once

discovered, you must enable Virtual Fabrics.

• Discover a Virtual Fabrics-enabled seed physical chassis running Fabric OS 6.2.0 or later with

Virtual Fabrics enabled, and at least one logical switch defined on the core switch. The physical

chassis displays as a virtual switch.

• Upgrade a physical chassis already in your SAN to Fabric OS 6.2.0 or later. Virtual Fabrics is

disabled by default. This switch displays as a legacy switch. Once upgraded, you must enable

Virtual Fabrics.

For more information about enabling Virtual Fabrics on a physical chassis, refer to “Enabling Virtual

Fabrics” on page 417.

Table 31 lists the Virtual Fabric-capable physical chassis and the number of logical switches

allowed for each of those physical chassis.

For the switches, any port can be assigned to any logical switch. However, depending on the

partition type, the backbone chassis have the port requirements shown in Table 32.

TABLE 31 Maximum number of logical switches per chassis

Physical chassis Number of logical switches allowed

40-port, 8 Gbps FC Switch 3

80-port, 8 Gbps FC Switch 4

48-port, 16 Gbps FC Switch 4

1. The maximum is 3 logical switches if you are using FC-FC routing.

384-port Backbone Chassis 8

192-port Backbone Chassis 8
