Operating Mode Configuration and Cabling
This section provides the instructions for cabling the specific operating mode
topology chosen for your storage solution.
Because the host side is a SCSI bus, SCSI IDs will need to be assigned to each
RAID Controller port or channel (CH 0 and CH 1). By default, the SCSI ID for
each port is ID 4 and ID 5 respectively. The ID is set using the Set Controller Port
ID setting in either the VT-100 interface or StorView, refer to your software user
guides.
For configurations that employ a single storage enclosure the default IDs will
most likely work for nearly all environments. Should the IDs need to be changed,
refer to the VT-100 Software Guide for procedures to set the SCSI IDs.
In configurations that expand the storage solution, each storage enclosure
beyond the first enclosure will need to have its SCSI ID changed from the default
setting to avoid SCSI ID conflicts. To change the IDs of the storage solution
enclosures after the hardware setup is complete. Connect the NexStor SATA
Communication RS-232 cable to the Service port on the next enclosure in the
stack. Power on that enclosure and set its IDs using the VT-100 menu function.
Repeat the process until you have changed all additional enclosures in the
expansion stack.
Simplex Mode
The Simplex (stand-alone) operating mode provides a single enclosure with a
single SCSI-SATA RAID Controller solution. This solution is designed for single
host and multiple host environments to achieve a low cost fault-tolerant disk
storage solution. The Expansion Connection provides the cabling solution for
expanding the number of enclosures and drives using the daisy-chain method of
connectivity.
Direct Attach Connection - Single Host (Single HBA)
