Preface
Onboard SATA controller
A SATA controller is integrated on the system board; up to four SATA hard disk
drives can be connected to the controller. The LSI Embedded MegaRAID
software (SATA Software RAID) supports RAID levels 0, 1 and 10.
For more information on configuring the controller, see section "Configuring the
onboard SATA controller" on page 51.
Optional SAS RAID controller
As an option you can order an SAS RAID controller.
Up to four SATA hard disk drives can be connected to this SAS RAID controller.
The embedded LSI MegaRAID software supports RAID levels 0, 1, 10, and
additional RAID levels 5 and 6 for SAS 1.0 and SAS 2.0.
Accessible drives
The first (top) bay contains the server's DVD drive.
The 5.25-inch bay below is available for one additional accessible drive
(CD/DVD drives or a magnetic tape drive).
The accessible drives cannot be replaced during operation.
Cooling
The efficient cooling system prevents high temperatures and results in lower fan
speed and less noise. The fans use less power.
Power supply
The server has a built-in power supply unit, which automatically sets itself to a
mains voltage in the range of 100 V - 240 V.
