Task 6: Making Data Connections
29
SAS Interface
The VTrak SAS subsystem has two SAS IN ports and two SAS OUT ports on
each RAID controller. The connection requires two (2) SAS SFF-8088 to SFF-
8088 cables, available from PROMISE.
To connect the SAS subsystem:
1.
Connect one of the SAS I/O ports on the
left
RAID controller to one of the
down
stream SAS ports on the HBA card in the VTrak appliance.
2.
Connect one of the SAS I/O ports on the
right
RAID controller to one of the
down
stream SAS ports on the HBA card in the VTrak appliance.
See the diagram below.
