Connecting Ports to Hosts
In a default array configuration, channels 0, 1, 4, and 5 are host channels, so you can
directly connect an FC array to four host computers. SFP connectors are plugged into
channels 0 and 4 on the upper controller and channels 1 and 5 on the lower
controller for this purpose.
If you want to connect an FC array to more than four host computers without
changing the default configuration, you can connect these four host channels to
ports on storage switches in a storage area network (SAN) configuration.
Note –
Connecting the Sun StorEdge 3510 RAID array to Fibre Channel HBAs on
the same channel that use different speeds (1 Gbyte & 2 Gbyte) is not supported. You
can, however, mix 1-Gbyte and 2-Gbyte Fibre Channel HBAs on different channels.
This limitation is due to the design of the Sun StorEdge 3510 RAID array's port
bypass circuitry and the inability of Fibre Channel to support auto-negotiation in a
multi-drop loop configuration.
Use fiber-optic cables to connect from one to four host channels to Fibre Channel
HBAs on your host computers or to other devices such as storage switches:
1. Connect a fiber-optic cable to an HBA or FC port on each host or storage switch
you want to connect to the array.
2. Connect the SFP connector at the other end of each of these fiber-optic cables to
host channel SFP connectors on the back of the array.
If there is no SFP connector in the port you want to use, first insert an SFP connector
into the port as described in
“Changing Your SFP Configuration” on page 4-13

Power-On Sequence
Power on the equipment in the following order, so that the host computer discovers
all connected arrays:
a. Expansion units
b. FC arrays
