2.5.3 The RAID Controller Module
The RAID controller module contains a main circuit board, a preinstalled 256MB capacity or
above DDR RAM DIMM module and the controller module interfaces. The controller module
contains no user-serviceable components. Except when installing/upgrading the cache mem-
ory inside, the controller module should never be removed or opened.
The heart of the RAID controller subsystem is the 320MB per second SCSI-to-SATA controller
board. The controller comes with two (2) pre-set SCSI-320 host channels, CH0 and CH1. The
subsystem connects to the host through a VHDCI SCSI input connector, while the output con-
nector is ready to connect external devices. (See Figure 2.9)
The docking connector at the rear of the controller board is used to connect the controller
module to the backplane board. A DDR RAM DIMM socket is strategically placed in an easily
accessible location on the controller board for easy insertion of the DDR RAM DIMM module.
2.5.4 Controller Module Interfaces
All external interfaces that connect to external devices are located on the controller module
rear panel shown in Figure 2.9. The interfaces are listed below.
Fig. 2.9 Controller Module Interfaces
• Host Ports: Two (2) SCSI-320 host channels (CH0 and CH1 in Figure 2.9) connect the
subsystem to the host through two (2) dual-stacked VHDCI SCSI connectors.
• Ethernet Ports: A single 10/100BaseT Ethernet port (located next to COM2) is used for
remote management through the network.
• COM ports: The controller module comes with two (2) COM ports. One port is used to
access the controller-embedded configuration utility through the network, and the other
connects to a UPS connection. .
• Levers: Two (2) levers located in the sides of the controller board rear panel provide easy
controller module installation and secure the controller module in place.
CAUTION!
Although the RAID controller can be removed, the only time you should touch the controller
itself is to install the memory modules. The RAID controller is built of sensitive components
and unnecessary tampering can damage the controller.
