DATA CENTER BEST PRACTICES

SAN Design and Best Practices 80 of 84

Gen 5 Fibre Channel Platforms

The Brocade FC16-48 and FC16-32 blades for the Brocade DCX 8510 Backbone and the Brocade 6520, 6510,

and 6505 Switches provide trunk groups with a maximum of 8 ports per trunk group. The trunking octet groups

are in the following blade port ranges: 0-7, 8-15, 16-23, 24-31, 32-39, and 40-47. (Trunk groups 32-39 and 40-

47 are obviously not applicable to FC16-32). Trunk boundary layout is on the faceplate of the blade.
