Galaxy Raid Installation and Hardware Reference Manual

GALAXY Components
Figure 1-7: Drive Tray
Each GALAXY subsystem comes with sixteen (16) drive trays. The front
panel of each drive tray (see
Figure 1-7
) contains a locking mechanism that
secures the drive tray to the enclosure and a latch that facilitates the removal
and installation of the drive tray. Two (2) status-indicating LEDs are also
located on the front of the drive tray. Retention screw holes are located on
the sides of the drive tray. These holes are reserved for securing hard drives
to the tray. Other retention screw holes are located on the surface of the tray
at the rear.
WARNING!
Be careful not to warp, twist, or contort the drive tray in any way (e.g., by
dropping it or resting heavy objects on it). The drive tray has been
customized to fit into the drive bays in the ES subsystem. If the drive bay
superstructure is deformed or altered, the drive trays may not fit into the
drive bay.
1.2.3 RAID
Controller
Modules
Figure 1-8: Controller Module
The RAID controller module that shipped with your subsystem contains a
metal bracket, a main circuit controller board, a management rear panel, and
a pre-installed 256MB capacity or above DDR RAM DIMM module. (See
Figure 1-8
) The controller module contains no user-serviceable
components. Except when installing/upgrading the cache memory inside,
the controller module should never be removed or opened.
WARNING!
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.
