Fibre Channel Cables - Hitachi g200 Reference Manual

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
• If you connect a storage system directly to FC host adapter with the
98
Fabric = ON and set to Point-to-Point.
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
FC-AL Available
P-to-P Available
Fabric 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.
Note: To connect to the server by the 16-Gbps direct connection,
the Fabric Emulation function of the Hitachi host adapter is required.
