Drive Bay Installation/Removal
Accessing the Drive Bays
SAS Drives: You do not need to access the inside of the chassis or remove power
to replace or swap SAS drives. Proceed to the next step for instructions. Typically
Large Form Factor 3.5" x 1" deep SAS drives are used. Optional conversion trays
are available to install Small Form Factor 2.5" drives.
Note: Refer to Supermicro's website for additional information at
supermicro.com/support/manuals/.
Hard Drive Midplane
The hard drives plug into a midplane that provides power, drive ID and bus
termination. This system uses an IR mode disk controller, offering users the most
fl exibility in creating fault tolerant software. Many open source platforms and modern
commercial operating systems support data redundancy as well as other techniques
to allow hot-swap maintenance of the storage devices. The midplane is already
pre-confi gured, so no jumper or switch confi gurations are required.
SAS 3.0 Controller
The SAS 3.0 controller (LSI 3008) is located on a mezzanine card that plugs into
the "SAS Controller Card" slot (see serverboard layout diagram for location).
SAS Drive Installation
These drives are mounted in drive carriers to simplify their installation and removal
from the chassis. The carriers also help promote proper airfl ow for the drives. For this
reason, even empty carriers without hard drives installed must remain in the chassis.
Removing a HDD Carrier from the Chassis (Figure 6-6)
1. Press the release button on the drive tray. This extends the drive tray handle.
2. Use the handle to pull the drive out of the chassis.
