This chapter introduces sample topologies, daisy-chaining, and external device connections 

for the RAID subsystem and discusses both the power on and power off procedures. 

The RAID subsystem supports two (2) SCSI channels and two (2) dual-stacked SCSI connec-

tors using SCSI-320 (also known as Ultra-320 SCSI), the latest iteration of the SCSI bus stan-

dard. SCSI-320 enables maximum data transfer rates of up to 320MB/second per channel 

between the host computers and the RAID subsystem. This is twice as fast as the Ultra-160 

standard, allowing users to store data at the fastest SCSI speeds available. 

One (1) SCSI cable is used for each RAID subsystem for host connection. A second SCSI cable 

is used to connect the second host channel. Use only high quality SCSI-320 cables from a rep-

utable manufacturer. To ensure optimum performance, it is necessary to use proper, high 

quality, durable SCSI-320 cables. Failure to do so will result in downgraded performance. 

The RAID subsystem is equipped with two (2) dual-stacked VHDCI SCSI connectors on the 

back of the enclosure for connecting the subsystem to a host computer and/or to daisy-chain 

other RAID subsystems. (See Figure 5.1) The connectors on the bottom of the controller rear 

panel are for data input and the connectors on the top are for data output.
