1-2 Serverboard Features

At the heart of the 1020C-3 lies the H8DCR-3 a dual processor serverboard de- signed to provide maximum performance. The H8DCR-3 is based on the nVidia nForce Pro 2200 and AMD-8132 chipset. Below are the main features of the H8DCR-3. See Figure 1-1 for a system block diagram of the chipset.

Processors

The H8DCR-3 supports dual 940-pin AMD OpteronTM 200 series processors. Please refer to our web site for a complete listing of supported processors.

Memory

The H8DCR-3 has eight 184-pin DIMM slots that can support up to 32 GB of reg- istered ECC DDR333/266 or up to 16 GB of registered ECC DDR400 SDRAM.

Note: The maximum memory capacity is halved if only one processor is installed. Memory is supported in both interleaved and non-interleaved confi gurations. See Section 5-6 for details.

SAS (Serial Attached SCSI)

An Adaptec 9410 SAS controller is integrated onboard the H8DCR-3 to provide a four-port SAS subsystem that features SES2 and is RAID 0, 1 and 10 supported. The SAS 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 SAS drives.
