MultiStage Topology
A Multistage topology describes a fabric in which two or more edge switches
connect to one or more core switches. Using 24-port QLogic 5800V Series
switches, the Multistage fabric shown in
has the following
characteristics:
Each link contributes up to 850MB of bandwidth between chassis.
Competition for this bandwidth is less than that of a cascade topology, but
greater than that of the mesh topology.
Latency between any two ports is no more than two chassis hops.
Seventy-two Fibre Channel SFP ports are available for devices.

Transparent Routing
\
The transparent routing feature provides inter-fabric routing to allow controlled
and limited access between devices on a QLogic 5800V Series switch (local)
fabric and devices on a remote fabric consisting of noncompliant switches made
by other vendors. For a list of switches that are supported in a remote fabric, see
the
QLogic 5800V Series Fibre Channel Switch Release Notes
. This type of
inter-fabric connection uses the Fibre Channel industry N-Port ID Virtualization
(NPIV), and makes local and remote devices accessible to each other while
maintaining the local and remote fabrics as separate fabrics.
