1-2 Serverboard Features
At the heart of the 4020C-T lies the H8DCE, a dual processor serverboard based
on the nVidia nForce Pro 2200/2050 chipset. Below are the main features of
the H8DCE. (See Figure 1-1 for a block diagram of the nForce Pro 2200/2050
chipset).
Processors
The H8DCE supports single or dual 940-pin AMD Opteron TM 200 series proces-
sors.
Memory
The H8DCE has eight 184-pin DIMM slots that can support up to 16 GB of regis-
tered ECC DDR400 or up to 32 GB of registered ECC DDR333/266 SDRAM. (The
maximum memory capacity is halved if only one processor is installed.) Memory
in supported in both interleaved and non-interleaved confi gurations. See Section
5-6 for details.
Serial ATA
A Serial ATA controller is integrated into the nForce Pro 2200/2050 chipset to
provide an eight-port Serial ATA subsystem, which is RAID 0 and 1 supported.
The Serial ATA drives are hot-swappable units.
Note: The operating system you use must have RAID support to enable the hot-
swap capability and RAID functions of the Serial ATA drives.
PCI Expansion Slots
The H8DCE has seven PCI expansion slots, which includes two (2) PCI-Express
x16 slots, two (2) PCI-Express x4 (which can support x8 cards) and three (3) 32-
bit, 33 MHz PCI (5V) slots.
Onboard Controllers/Ports
One fl oppy drive controller and two onboard ATA/133 controllers are provided to
support up to four IDE hard drives or ATAPI devices. The I/O ports include one COM
port (a COM2 header is located on the serverboard), a VGA (monitor) port, a parallel
port, two USB ports, PS/2 mouse and keyboard ports and two gigabit Ethernet ports.
Two front side USB ports are also included on the front of the chassis.
