VTrak S3000 Quick Start Guide
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:
Connect a SAS cable from the Expansion port on the left RAID controller to
1.
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:
Connect a SAS cable from the SAS OUT port on left I/O module to the SAS
1.
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.
