1-2 Serverboard Features
At the heart of the SuperServer 1025W-U/1025W-UR lies the X7DWU, a dual pro-
cessor serverboard based on Intel's 5400 chipset. Below are the main features of
the X7DWU (see Figure 1-1 for a block diagram of the chipset).
Processors
The X7DWU supports single or dual 771-pin Intel Xeon 5400/5300LV/5200/5100LV
series processors at a FSB speed of 1600/1333/1066 MHz. Please refer to the
serverboard description pages on our web site for a complete listing of supported
processors.
Memory
The X7DWU has eight 240-pin DIMM sockets that can support up to 64 GB of
ECC FBD (Fully Buffered DIMM) DDR2-800 (fully supported with 1600 MHz CPUs
only), DDR2-667 or DDR2-533 SDRAM. The memory is an interleaved confi gura-
tion, 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 X7DWU 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.
Serial ATA
An on-chip (ESB2) SATA controller is integrated into the X7DWU to provide a six-
port, 3 Gb/sec Serial ATA subsystem, which is RAID 0, 1 and 10 supported (RAID 5
also supported with Windows OS). The SATA drives are hot-swappable units. Note:
The operating system you use must have RAID support to enable the hot-swap
capability and RAID function 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.
