Fibre to SAS/SATA II RAID Subsystem
86 User Manual
Channel Topology
Each Fibre Channel can be configured to the following Topology options: Fabric,
Point-to-Point, Loop or Auto. The default Topology is set to “Auto”, which takes
precedence of Loop Topology. Restarting the RAID controller is needed for any topology
change to take effect. The current connection topology is shown at end of the row. You
have to click the “Fibre Channel Config” link again from the menu frame to refresh
the current topology information. Note that current topology is shown as “None” when
no successful connection is made for the channel.
Hard Loop ID
This setting is effective only under Loop topology. When enabled, you can manually set
the Loop ID in the range from 0 to 125. Make sure this hard assigned ID does not conflict
with other devices on the same loop, otherwise the channel will be disabled. It is a good
practice to disable the hard loop ID and let the loop itself auto-arrange the Loop ID.
NOTE: For reliable operation of the RAID subsystem and depending
on how the subsystem is connected, it is recommended to setup
Channel Speed and Channel Topology as follows:
RAID subsystem is
connected to: Channel Speed
setting: Channel Topology
setting:
4Gb FC switch 4Gb Fabric
2Gb FC switch 2Gb Fabric
4Gb FC HBA
(no switch)
4Gb Loop
2Gb FC HBA
(no switch)
2Gb Loop
“Fabric” topology is used when there is switch.
“Loop” topology is used when there is no switch.
The Speed setting follows the FC switch speed if there is switch. If there is
no FC switch, the Speed setting follows the FC HBA speed.
