Intel SRCSAS18E 用户手册

Intel® RAID Controller SRCSAS18E User’s Guide

Note: System throughput problems can occur if using SAS cables that do not come with the

RAID controller and that are not the correct type. To minimize the potential for problems:
- Use cables no longer than ten meters for SAS and one meter for SATA. It is better to use

the shortest possible cables. The cable length should be reduced by about one foot (.33

meters) if using a backplane.
- You may connect one device per SATA/SAS cable either as a device or as an expander.
- Route SAS cables carefully
- Use only “straight” SAS cables, not “cross-over” SAS cables.

7. Power On Server

Replace the chassis cover and reconnect the AC power cord(s). Power up the SAS and

SATA devices before or at the same time as the server. If the computer is powered up

before a SAS or SATA device, the device might not be recognized.
During the boot, a BIOS message appears. The firmware takes several seconds to

initialize.

The configuration utility prompt times out after several seconds. The second portion of the

BIOS message displays the RAID Controller SRCSAS18E number, firmware version, and

cache SDRAM size. The numbering of the controllers follows the PCI slot scanning order

used by the host mainboard.

If you want to run the BIOS Console 2 utility, press the appropriate keys when this

message appears:

SAS Device Cables

This section describes the cables used on the SAS controller and provides step-by-step

instructions for connecting SAS and SATA hard disk drives to the SAS RAID controller.

The SAS and SATA protocols use a thin, 7-wire connector.

Note: Use only “straight” SAS cables, not “cross-over” SAS cables.

Figure 3 displays the SAS cable used to connect the internal connectors on a SAS RAID

controller to SAS drives.
