Subsystem Connection and Operation
This chapter introduces sample topologies, daisy-chaining, and external
device connections for the FALCON II and discusses both the power on
and power off procedures.
4.1 SCSI Connection Overview
The FALCON II subsystem supports two (2) SCSI channels and two (2)
dual-stacked SCSI connectors using SCSI-320 (also known as Ultra-320
SCSI), the latest iteration of the SCSI bus standard. SCSI-320 enables
maximum data transfer rates of up to 320MB/second per channel between
the host computers and FALCON II. This is twice as fast as the Ultra-160
standard, allowing users to store data at the fastest SCSI speeds available.
4.1.1 SCSI Cables
One (1) SCSI cable (IFT-9270UJBODCab) is provided with each
FALCON II for host connection. If you wish to use a second SCSI
cable to connect the second host channel, a second cable must be
purchased separately. Purchase only high quality SCSI-320 cables from a
reputable manufacturer. To ensure optimum FALCON II
performance, it is necessary to use proper, high quality, durable SCSI-320
cables. Failure to do so will result in downgraded performance.
4.1.2 SCSI Port on the Controller Rear Panel
The FALCON II 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 FALCON II’s. (See Figure 4-1)
The connectors on the bottom of the controller rear panel are for data input
and the connectors on the top are for data output.
