Procedure for Cascading RAID Subsystems
1. Connect the RAID subsystem to application servers. Most host adapter cards
provide VHDCI connectors. Use VHDCI-to-VHDCI cables for host connection.
Connect host adapters and the SCSI IN ports on the RAID subsystem.
2. If you wish to connect more than one subsystem, use VHDCI-to-VHDCI cables to
connect the SCSI OUT ports of the primary RAID subsystem (one that is directly
connected to servers) and the SCSI IN ports on the next subsystem.
3. The logical configurations (e.g., logical drives) created in the primary and the
cascaded subsystems occupy different ID/LUNs on a host bus thus connected. See
the diagram below for details.
