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.
