SATA DOMs require power to be provided by the storage array using the P4
power cable that is normally plugged into the boot drive module backplane. The
P4 power cable needs to be removed from the boot drive module backplane and
attached to the power adapter cable that came with your SATA DOM.
The USB DOM obtains its power directly from the server board. When using a
USB DOM, you must disconnect the mini USB cable that is connected to the USB
header on the server board. This disables the mini USB port on the front of the
chassis.
Intel storage server 55R212MC2 Boot Drive Options
In the Intel Storage Server SSR2 1 2MC2, the twelve SATA/SAS drives are
connected via the mini-SAS to mini-SAS cable that resides between Intel
SRCSATAWB RAID controller and the backplane. Drives can be either SATA or
SAS. The server board includes a dual-mode 4-port SAS controller which supports
both SAS and SATA hard disk drives. This controller is capable of data transfer
rates up to 3.0 Gbps per port. The storage array enables the SAS controller and
configures the two black SATA ports on the server board to function as SATA
ports. In this configuration, the four blue ports can be used as either SAS or SATA
ports.
See the Intel Server Board S5000PSL User Guide for information on setting up the
server board to support either SATA or SAS options. In the Intel Storage Server
SSR2 1 2MC2, the two internal boot drives are connected to the two black SATA
ports and can be used with SATA drives. You can optionally remove one of the
SAS port connections and connect it to the boot drive module. This would
eliminate one of the four SAS lanes going to the backplane.
See your operating system or third-party storage software documentation for
instructions on loading drivers and configuring the storage server.
