1.1.1 Product Introduction
This hardware manual briefly introduces the Falcon 24-bay, SCSI (SCSI-
320)-to-Serial ATA (SATA) RAID subsystem as shown in Figure 1-1.
Figure 1-1: Falcon 24-bay SATA RAID Subsystem
The Falcon s ubsystem is managed by a single SCSI-to-SATA RAID controller . The
subsystem has two (2) 320MB per second (MBps) SCSI-320 host channels that are
interfaced through four (4) separate VHDCI ports (two per channel). The additional
VHDCIs facilitate connection to expansion enclosures or HBAs on the host bus. The
onboard SATA chips provide twenty-four (24) 3Gbps SATA drive channels each
dedicated to the connection of a SATA disk drive. The controller board comes with a
pre-installed 256MB DDR RAM DIMM module and can support memory modules with
the capacities up to 2GB.
The controller module is accessed through the rear of the subsystem. Four (4) VHDCI
SCSI ports on the controller module connect the enclosure to expansion enclosures or
application servers equipped with SCSI-320 HBA.
Two (2) RS-232C (audio jack) serial port connectors are located on the controller module
faceplate on the rear of the subsystem. One serial port (COM1) enables serial
communication between the controller and an external PC running a terminal emulation
software that can be used to configure and manage the RAID subsystem. The second
serial port (COM2) can be used as signal lines to an uninterruptible power supply (UPS).
(See Appendix B) An RJ-45 Ethernet connector allows for telnet access and web-based
management of the subsystem using the included RAIDWatch Manager software.
