"SAS Device Cables"
Section 2.4.1, "Connecting the ServeRAID-MR10M Controller
to a Drive Enclosure,"
the physical disks and the expanders.
The maximum cable length is six meters. You can connect one
device per SAS PHY unless you use an expander.
System throughput problems can occur if the SAS cables are
not the correct type. To minimize the potential for problems:
a. Use cables no longer than six meters (using shorter cables
is preferred)
b. Use cables that meet the SAS specification
c. Route the SAS cables carefully
Step 9. Turn on the Power to the System
Reinstall the computer cover and reconnect the AC power
cords; then, turn on the power to the computer.
Make sure that the power is turned on to the SAS devices and
the SATA II devices before or at the same time as the host
computer. If the power is turned on to the computer before it is
turned on to the devices, the computer might not recognize the
devices.
During 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 ServeRAID-MR10M controller
number, firmware version, and cache SDRAM size. The
numbering of the controller follows the PCI slot scanning order
used by the host mainboard.
Step 10. Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to configure the
physical arrays and the logical drives. When the message
Press <Ctrl><H> for WebBIOS appears on the screen, press
CTRL+H immediately to run the utility.
Step 11. Install the Operating System Driver
The RAID controller can operate under various operating
systems. To operate under these operating systems, you must
install the software drivers.The ServeRAID-MR Support CD
