High-Performance SAN Tips and Techniques

In the high-performance SAN configuration, the switches communicate with the Sun StorEdge 3510 FC array host ports using a fabric loop (FL_port) mode. This enables every Fibre Channel host connection within the Sun StorEdge 3510 FC array to send and receive data from servers, resulting in optimum performance.

Use of fabric loop (FL_port) connections between a Sun StorEdge 3510 FC array and fabric switches enables up to 1024 total LUNs to be presented to servers. However, using such a large number of LUNs adversely affects performance.
