Fibre to SAS/SATA Disk Array
User Manual 125
NOTE: For reliable operation of the Disk Array and depending on
how the subsystem is connected, it is recommended to setup
Channel Speed and Channel Topology as follows:
Disk Array is
connected to: Channel Speed
setting: Channel Topology
setting:
8Gb FC switch 8Gb Fabric
4Gb FC switch 4Gb Fabric
8Gb FC HBA
(no switch)
8Gb Loop
4Gb FC HBA
(no switch)
4Gb 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.
