Serverboard Features
At the heart of the 2021M-T2R+/2021M-82R+ lies the H8DME-2/H8DM8-2, a dual
processor serverboard based on the nVidia MCP55 Pro chipset and designed to
provide maximum performance. Below are the main features of the H8DME-2/
H8DM8-2. (See Figure 1-1 for a block diagram of the MCP55 Pro chipset).
Processors
The H8DME-2/H8DM8-2 supports single or dual AMD Opteron 2000 Series, Socket
F type processors. Please refer to the serverboard description pages on our web
site for a complete listing of supported processors (www.supermicro.com/aplus).
Memory
The H8DME-2/H8DM8-2 has sixteen 240-pin DIMM slots that can support up to
32/32/64 GB of registered ECC DDR2-667/533/400 SDRAM. The memory operates
in an interleaved confi guration and requires requires modules of the same size and
speed to be installed two at a time. See Chapter 5 Section 5 for details.
Serial ATA
A SATA controller is integrated into the chipset to provide a six-port Serial ATA
subsystem, which is RAID 0, 1, 0+1, 5 and JBOD 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 function of the Serial ATA drives.
