Fibre Channel cables
When constructing a system with the direct connection or Fibre Channel switch
connection, consider the following:
■
If you connect a storage system to a FC host adapter through a switch, set Fabric = ON
and set to Point-to-Point.
■
If you connect a storage system directly to FC host adapter with the following fabric
topology:
●
For 2, 4 or 8 Gbps, set the storage port to Fabric = OFF and Connection Type FC-AL
(Fibre Channel Arbitrated Loop).
●
For 16 or 32 Gbps, set the storage port to Fabric = OFF and Connection Type P-to-P
(Point-to-Point).
For the 8-Gbps Fibre Channel ports, the combinations between data-transfer speeds
and connection types are as follows:
Connection
type
Data transfer speeds for 8-Gbps ports
2 Gbps 4 Gbps 8 Gbps Auto
FC-AL Available Available Available Available
(default)
P-to-P Available Available Available Available
Fabric Available Available Available Available
For the 16-Gbps Fibre Channel ports and for 16-Gbps SFP added to the 4- port FC 32-
Gbps package, the combinations between data-transfer speeds and connection types
are as follows:

Notes:
1. If this combination is specified, the maximum transfer speed automatically
specified is 8 Gbps.
2. If this default value is set, Fabric is set to ON automatically.
