1.2.1 Drive Trays
Figure 1-6: Drive Tray Front View
The SecurStor 16I subsystem comes with sixteen (16) drive trays (see
Figure 1-6 ) designed to accommodate separately purchased, standard 1-inch
pitch, 3.5-inch SATA-II disk drives. The drive bays are accessible from the
enclosure front panel. Two (2) LEDs on the front bezel indicate the
operating statuses. A key-lock on each drive tray secures the hard drive in
place, while a release button enables fast retrieval of a hard drive.
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 of the subsystem. If the drive bay
superstructure is deformed or altered, the drive trays may not fit into the
drive bays.
1.2.2 The RAID Controller Module
The default size for the DDR RAID controller module is 512MB. RAID
controller module contains a main circuit board, a preinstalled 512MB
capacity or above DDR RAM DIMM module, and the controller module
interfaces. The controller module contains no user-serviceable components
and should never be removed or opened, except when installing/upgrading
the cache memory inside.
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.
The heart of the SecurStor 16I RAID controller subsystem is the iSCSI-to-
SATA controller board. The controller comes with four (4) GbE Ethernet
host ports. The subsystem connects to the host through RJ-45 connectors,
while the connectors are also ready to connect to one or more network
