1-2 Serverboard Features

At the heart of the A+ SERVER 2022G-URF lies the H8DGU-F, a dual processor
serverboard based on the AMD SR5670/SP5100 chipset. Below are the main
features of the H8DGU-F. (See Figure 1-1 for a block diagram of the chipset).

Processors

The H8DGU-F supports single or dual AMD Opteron 6100 Series processors in
Socket G34 type sockets. Please refer to our web site for a complete listing of
supported processors (www.supermicro.com).

Memory

The H8DGU-F has sixteen single/dual/tri/quad channel 240-pin DIMM sockets
that can support up to 128 GB of ECC/Non-ECC Unbuffered, 512 GB of
ECC Low-prole Registered LRDIMM, or 512 GB of ECC Registered DIMM
DDR3-1600/1333/1066 Mhz speed, SDRAM memory. Please refer to Chapter 5
for installing memory.

UIO

The H8DGU-F is a specially -designed server board that features Super micro's UIO
(Universal I/O) technology. UIO serverbo ards have a PCI Express x8 slot that can
support any one of several types of UIO car d types to add SAS ports, additional
LAN ports, etc. to the server board. This allows the user to tailor the ser verboard
to their own needs.
Note: the server does not come with a UIO card in stalled.

Serial ATA

An on-chip (SP5100) SATA controller is integrated into the H8 DGU-F to provide
a six-port, 3 Gb/sec SATA subsystem, which is RAID 0, 1, and 10 supp orted. The
SATA drives are hot-swappable units.
Note: You must have RAID set up to enable the hot-swap capabilit y of the SATA
drives. Documentation on RAI D setup guidelines can be found on our web site.
