1-2 Serverboard Features
At the heart of the AS1021M-T2/1021M-82 lies the H8DMR-i2/H8DMR-82, a dual
processor serverboard based on nVidia's MCP55 Pro chipset. Below are the main
features of the H8DMR-i2/H8DMR-82 (see Figure 1-1 for a block diagram of the
chipset).
Processors
The H8DMR-i2/H8DMR-82 supports single or dual AMD Socket F type processors.
Please refer to the serverboard description pages on our web site for a complete
listing of supported processors.
Memory
The H8DMR-i2/H8DMR-82 has eight 240-pin DIMM sockets that can support up to
16 GB of registered ECC DDR2-667/533 or 32 GB of registered ECC DDR2-400
SDRAM. The memory may be installed to provide an interleaved confi guration,
which requires modules of the same size and speed to be installed in pairs. Please
refer to the Installing Memory section for details.
Serial ATA
An on-chip SATA controller is integrated into the H8DMR-i2/H8DMR-82 to provide a
six-port, 3 Gb/sec Serial ATA subsystem, which is RAID 0, 1 and 0+ 1 supported.
The SATA 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 Serial ATA drives.
Onboard SCSI (1021M-82 only)
An onboard Adaptec AIC-7902W dual-channel SCSI controller in integrated into the
H8DMR-82, which supports 80-pin SCA Ultra320 SCSI hard drives. (Standard 1"
drives are supported. SCA = Single Connection Attachment.) The SCSI drives are
connected to an SCA backplane that provides power, bus termination and confi gu-
ration settings. The SCSI 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 SCSI drives.
