Fabric topologies

A SAN fabric topology defines the arrangement of Fibre Channel switches in a fabric. This section
describes the HP-supported SAN fabric topologies.
There are three approaches to designing a SAN. You can implement:
An HP standard SAN fabric topology design
A subset or variation of an HP standard SAN fabric topology design
A custom SAN fabric topology design
Regardless of which approach you use, the SAN design must adhere to the SAN design rules described
in the following chapters:
"H-series switches and fabric
"B-series switches and fabric
"C-series Fibre Channel and FCoE switches and fabric
"M-series switches and fabric
"SAN fabric connectivity and switch interoperability
"Heterogeneous server
"MSA storage system
"EVA storage system
"XP and VA storage system
