Chapter 1: Introduction
2Gb disk drives in another dual-loop (e.g., CH4 and CH5) is allowed.
Do not include both 4Gb and 2Gb disk drives in a logical drive
configuration.
Cooling module speed detection:
If any of the embedded temperature
sensors reports a reading breaching preset threshold, the cooling modules
will automatically raise its rotation speed.
RCC (Redundant Controller Communications) channels:
The F16F
subsystem comes with six (6), dedicated, SATA channels that are
exclusively used for inter-controller communications. These paths are
routed through a common backplane and are non user-serviceable.
Docking connectors:
The FCI docking connectors at the rear of the
controller boards connect the controller module to the backplane board.
1.2.3.1 Controller Module Interfaces
The controller interfaces are diagrammed and described as follows:
Figure 1-18: RAID Controller Faceplate
COM ports:
Each controller module comes with two (2) COM ports.
COM1
is used for accessing the firmware-embedded text-based
configuration utility through RS-232 serial port connection. A
management session should be invoked by a VT-100 compatible
terminal emulation program. An audio-jack to DB9 cable is shipped
with a single-controller model. A similar Y-cable that features two
audio jacks is shipped with dual-controller models. (PN: IFT-
9270AYCab)
The two (2) audio jacks of the Y-cable connects the COM1 ports on
partner RAID controllers so that a management session will not be
disrupted during controller failover/failback.
The
COM2
serial port connects to the serial ports on UPS
(Uninterruptible Power Supply) devices. An optional audio jack to DB-
9 cable (PN: IFT-9270CUPSCab) or a similar Y-cable (PN: IFT-
