Serverboard Features
At the heart of the SuperServer 7044A-82R lies the X6DA8-G2, a dual processor
serverboard based on the Intel E7525 chipset and designed to provide maximum
performance. Below are the main features of the X6DA8-G2. (See Figure 1-1 for
a block diagram of the E7525 chipset).
Processors
The X6DA8-G2 supports single or dual 604-pin Intel Nocona
FSB speed of 800 MHz. Please refer to the serverboard description pages on our
web site for a complete listing of supported processors (http://
www.supermicro.com).
Memory
The X6DA8-G2 has eight 240-pin DIMM slots that can support up to 16 GB of
registered ECC DDR2-400 (PC3200) SDRAM. The memory is an interleaved
configuration, which requires modules of the same size and speed to be installed
in pairs.
Onboard SCSI
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 X6DA8-G2 provides two LVD Ultra320 SCSI ports.
PCI Expansion Slots
The X6DA8-G2 has six PCI expansion slots, which includes one x16@4GB/sec
PCI-Express slot, one x4@2GB/sec PCI-Express slot, three 64-bit PCI-X slots
(one 64-bit PCI-X 133 slot, one PCI-X 100 slot, one PCI-X 100MHz ZCR slot) and
one 32-bit 33MHz PCI slot (w/PCI graphics card support).
Onboard Controllers/Ports
One floppy drive controller and two onboard ATA/100 controllers are provided to
support up to four hard drives or ATAPI devices. The color-coded I/O ports
include two COM ports, a parallel port, four USB 2.0 ports, PS/2 mouse and
keyboard ports two G-bit Ethernet ports and Line-in, Line-out and Mic jacks. Two
