Best Practices for the Sun StorEdge 3510 and 3511 FC Arrays

■
Use of fabric point-to-point (F_port) connections between an array and fabric
switches limits to 128 the total number of LUNs that can be presented. Fibre
channel standards allow only one ID per port when operating point-to-point
protocols, resulting in a maximum of four IDs, with a maximum of 32 LUNs each,
supporting up to 128 LUNs.
■
When a fabric switch is connected to one port of channel 0 or channel 1 of a Sun
StorEdge 3511 SATA array, no connections can be made with the other three ports
of that channel. If channel 0 (port FC0) is connected to a fabric switch, for
example, the second port for channel 0 on that controller, and the FC0 ports on a
redundant controller, cannot be used. Similarly, if channel 1 (port FC1) is
connected to a fabric switch, the second FC1 port on that controller and the FC1
ports on a redundant controller, cannot be used.
