Daisy Chain

5.3.1

Daisy Chain Topology

 

The RAID subsystem offers the flexibility to daisy chain additional RAID subsystems to meet

 

increasing storage needs. In a daisy chain topology, the RAID subsystem can be connected to

 

each other. The IN ports on the first subsystem are both connected to separate SCSI-320 host

 

computers. The OUT ports on the first subsystem are connected to the IN ports on the second

 

subsystem. This process is repeated for the third subsystem.

Daisy Chain Procedures

 

1.

Connect the RAID subsystem to the host computer. Use the VHDCI to VHDCI SCSI cable

 

 

that was provided in the packaging box. Attach one end to the host computer and the

 

 

other end to the SCSI IN port on the back of the RAID subsystem.

 

2.

Daisy chain subsystems. If you wish to connect more than one subsystem, an extra VHDCI

 

 

to VHDCI SCSI cable is required. Attach one end of the cable to the SCSI OUT port and

 

 

the other end to the SCSI IN port in the next subsystem.

 

3.

Assign chassis IDs. Each chassis must be assigned a unique chassis ID before being pow-

 

 

ered on. The chassis ID for the first RAID subsystem is 0. The chassis IDs for the subsys-

 

 

tems connected to the first RAID subsystem are from 1 to 16. You can assign chassis IDs

 

 

through the LCD panel on the subsystem, firmware, or Bosch RAIDWatch management

 

 

software. (See Figure 5.4)

 

4.

Create redundant host paths. If access to data is a critical requirement, redundant data

 

 

paths to different LDs (logical drives) or logical volumes (LVs) can be created. To do this,

 

 

logical units (LDs or LVs) are mapped to both host channels (CH0 and CH1 in Figure 5.4.)

 

 

This will ensure that if one host computer fails, the second host computer will be able to

 

 

access the logical units on that host computer.
