1-2 Serverboard Features
At the heart of the SuperServer 8044T-8R lies the X6QT8, a quad processor
serverboard based on the Intel E8501 chipset. Below are the main features of the
X6QT8. (See Figure 1-1 for a block diagram of the E8501 chipset).
Processors
The X6QT8 supports four 604-pin Intel Xeon 7100 Series processors at a FSB
speed of 800/667 MHz. Please refer to the serverboard description pages on our
web site for a complete listing of supported processors (www.supermicro.com).
Memory
The X6QT8 has sixteen 240-pin DIMM slots that can support up to 64 GB of ECC
DDR2-400 SDRAM. The memory operates in an interleaved confi guration and re-
quires requires modules of the same size and speed to be installed two at a time.
See Chapter 5 Section 5 for details.
Onboard SCSI
An onboard Adaptec AIC-7902W dual-channel SCSI controller in integrated into the
X6QT8, which supports eight 80-pin SCA Ultra320 SCSI hard drives. RAID 0, 1,
10 and JBOD are supported. The SCSI drives are connected to an SCA backplane
that provides power, bus termination and confi guration settings. The SCSI drives
are hot-swappable units. Note: HostRAID supports only four drives.
Serial ATA
A SATA controller is integrated into the South Bridge of the E8501 chipset to pro-
vide a two-port SATA subsystem, which is RAID 0, 1 and JBOD supported. The
SATA drives are hot-swappable units.
PCI Expansion Slots
The X6QT8 has six PCI expansion slots, which includes one PCI-Express x8 slot,
one PCI-Express x4 slot, three 64-bit 133 MHz PCI-X slots and one 64-bit 100 MHz
PCI-X slot. (The 100 MHz PCI-X slot supports Zero Channel RAID.)
