High degree of SCSI disk fault tolerance and advanced disk array management
!
features through the use of RAID technology, if an optional RAID controller is
installed in the BSU.
As application requirements increase, you can expand your server system with
additional processors, additional memory, add-in boards and peripheral devices.
Your server system features the following major components:
Up to four or eight high-performance Pentium III Xeon processors packaged in
!
Single Edge Contact (S.E.C.) cartridges.
Up to 16 GB of ECC SDRAM four way interleaved memory.
!
Ten Hot-Plug PCI expansion slots that support eight 64 bit and two 32 bit PCI
!
boards. The Hot-Plug PCI feature is useable only when Operating System support is
available.
Embedded PC-compatible support (serial, parallel, mouse, keyboard, diskette, IDE,
!
USB, LAN, and video).
Integrated onboard ATI RAGE IIC Super Video Graphics Array (SVGA) controller
!
with 4 MB of video memory.
Adaptec AIC7899 SCSI controller providing two channel Ultra 160/m SCSI
!
interfaces.
Integrated onboard Network Interface Controller (NIC), an Intel 82559 PCI LAN
!
controller for 10 or 100 Mbps Ethernet networks with a RJ-45 Ethernet connector.
Single Channel enhanced IDE controller.
!
Chassis that holds up to 6 drives; two hot-swap bays for Ultra 160/m SCSI hard
!
drives; three media bays with a CD-ROM installed; and a 3.5-inch bay with a
diskette drive.
Two hot-swap SCSI hard disk drive bays accessible from the front of the chassis.
!
The drives can be swapped in or out of the system without powering down, if RAID
is configured in the system.
Eight hot-swap SCSI hard disk drive bays accessible from the front of the DEU. The
!
drives can be swapped in or out of the system without powering down, if RAID is
configured in the BSU.
SCSI backplane is Ultra 160/m capable.
!
Integrated dual Universal Serial Bus (USB) ports. Note that the USB ports do not
!
support the keyboard or mouse.
One standard power supply for a four CPU configuration. Two power supplies are
!
standard for an eight CPU configuration. When an additional power supply is
installed, both the standard and additional redundant power supplies become hot
swappable.
Hardware monitors (temperature, fans, and voltage) and software monitors to
!
indicate failures.
One power inter-lock switch for the front panel of the chassis.
