Drive Trays

 

Fig. 2.8 Drive Tray Front View

 

The RAID subsystem comes with twelve (12) drive trays (see Figure 2.8) designed to accom-

 

modate separately purchased, standard 1-inch pitch, 3.5-inch disk drives. The drive bays are

 

easily accessible from the front of the enclosure. Two (2) LEDs on the front of the tray indi-

 

cate the drive status. A key-lock on each drive tray secures the hard drive in place, while an

 

easily accessible release button ensures fast and efficient drive hot-swapping.

 

 

 

CAUTION!

 

Be careful not to warp, twist, or contort the drive tray in any way (e.g., by dropping it or rest-

 

ing heavy objects on it). The drive tray has been customized to fit into the drive bays in the

 

RAID subsystem. If the drive bay superstructure is deformed or altered, the drive trays may

 

not fit into the drive bay.

 

 

2.3.3

The RAID Controller Module

 

The RAID controller module contains a main circuit board, a preinstalled 1 GB 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.

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.

The heart of the RAID controller subsystem is the iSCSI-to-SATA controller board. The control- ler comes with two (2) 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 switches, enabling access to your storage volumes in complex configurations such as data- sharing or network zoning.

The docking connector at the rear of the controller board connects 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.
