1-2 Serverboard Features
At the heart of the SuperServer 6025B-UR lies the X7DBU, a dual processor
serverboard based on the Intel 5000P chipset and designed to provide maximum
performance. Below are the main features of the X7DBU. (See Figure 1-1 for a
block diagram of the 5000P chipset).
Processors
The X7DBU supports single or dual 771-pin Intel Xeon 5300/5100/5000 series pro-
cessors at a FSB speed of 1333/1066/667 MHz. Please refer to the serverboard
description pages on our web site for a complete listing of supported processors.
Memory
The X7DBU has eight 240-pin DIMM sockets that can support up to 32 GB of ECC
FBD (Fully Buffered DIMM) DDR2-667 or DDR2-533 SDRAM. The memory is an
interleaved confi guration, which requires modules of the same size and speed to be
installed in pairs. Please refer to Chapter 5 for memory speed jumper settings.
UIO
The X7DBU is a specially-designed serverboard that features Supermicro's UIO
(Universal I/O) technology. UIO serverboards have a PCI-Express x8 connector
that can support any one of several types of UIO card types to add SAS ports,
additional LAN ports, etc. to the serverboard. This allows the user to tailor the
serverboard to their own needs. Note: the 6025B-UR does not come with a UIO
card installed.
Serial ATA
An on-chip (ESB2) SATA controller is integrated into the X7DBU to provide a six-
port, 3 Gb/sec Serial ATA subsystem, which is RAID 0, 1, 10 and 5 supported. The
Serial ATA drives are hot-swappable units. Note: You must have RAID set up
to enable the hot-swap capability of the Serial ATA drives.
Onboard Controllers/Ports
One fl oppy drive controller and one onboard ATA/100 controller are provided to
support up to two IDE hard drives or ATAPI devices. The color-coded I/O ports
include one COM port, a VGA (monitor) port, two USB 2.0 ports, PS/2 mouse and
keyboard ports and two gigabit Ethernet ports.
