1-2 Serverboard Features
At the heart of the SuperServer 6015B-UR/6015B-U/6015B-NTR/6015B-NT lies 
the X7DBU, a dual processor serverboard based on Intel's 5000P chipset. Below 
are the main features of the X7DBU (see Figure 1-1 for a block diagram of the 
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 (6015B-UR/6015B-U)
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 6015B-UR/6015B-U 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 and 10 supported. 
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.
