Task 6: Making Data Connections
33
SAS Expansion Connections (Optional)
You can expand the storage capacity of the VTrak RAID subsystem by adding
VTrak JBOD enclosures. Connecting a pair of subsystems requires two (2) SAS
SFF-8088 to SFF-8088 cables, available from PROMISE.
A VTrak RAID subsystem supports up to four (4) VTrak JBOD enclosures.
To connect the VTrak RAID subsystem to a VTrak JBOD enclosure:
1.
Connect a SAS cable from the Expansion port on the
left
RAID controller to
the SAS IN port on the
left
I/O module.
2.
Connect a SAS cable from the Expansion port on the
right
RAID controller to
the SAS IN port on the
right
I/O module.
See the diagram below.
To connect one VTrak JBOD enclosure to another VTrak JBOD enclosure:
1.
Connect a SAS cable from the SAS OUT port on
left
I/O module to the SAS
IN port on the
left
I/O module.
2.
Connect a SAS cable from the SAS OUT port on
right
I/O module to the SAS
IN port on the
right
I/O module.
See the diagram below.
