1-2 Serverboard Features
At the heart of the SuperServer 8052-8/8052-6 lies the P4QH8/P4QH6, a
quad Xeon processor serverboard based on ServerWorks GC-HE chipset
and designed to provide maximum performance in a four-way system. Be-
low are the main features of the P4QH8/P4QH6. (See Figure 1-1 for a block
diagram of the GC-HE chipset.)
Processors
The P4QH8/P4QH6 supports up to four Intel Xeon processors of up to 2.8
GHz at a 400 MHz front side (system) bus speed. Please refer to the
support section of our web site for a complete listing of supported proces-
sors (http://www.supermicro.com/TechSupport.htm).
Memory
The P4QH8/P4QH6 has an MEC card that plugs into a special slot on the
serverboard. The MEC card has 16 184-pin DIMM slots that can support up
to 32 GB of ECC registered DDR200 (PC1600) SDRAM. Module sizes of
128MB, 256MB, 512MB 1GB and 2GB may be used to populate the DIMM
slots. (DDR266 is also supported, but only at 200 MHz.)
Onboard SCSI
8052-8: Onboard SCSI is provided with an Adaptec AIC-7902 SCSI chip,
which supports dual channel, Ultra320 SCSI at a throughput of 320 MB/sec
for each channel. The P4QH8 provides two Ultra320 SCSI ports.
8052-6: Onboard SCSI is provided with an Adaptec AIC-7899 SCSI chip,
which supports dual channel, Ultra160 SCSI at a throughput of 160 MB/sec
for each channel. The P4QH6 provides two Ultra160 SCSI ports.
PCI Expansion Slots
The P4QH8/P4QH6 has a total of six 64-bit 100 MHz PCI-X slots.
Onboard Controllers/Ports
One floppy drive controller and two onboard ATA/100 controllers, which
support up to four hard drives or ATAPI devices. The color-coded I/O ports
include a VGA port, one COM port, a parallel port, two USB ports, PS/2
