ERVER 1025W-U/1025W-UR Manual

1-2

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).

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.

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.

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.

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.

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.
