Server Board Features
At the heart of the system is a four processor serverboard based on the AMD Opteron chipset and
designed to provide maximum performance. Below are the main features of the serverboard.
Processors
The serverboard supports four AMD 6100/6200/6300 series Opteron processors. Each processor
sits in a 1944-pin “G34” socket and is interconnected via HyperTransport (HT) 3.0 link support,
see the next subsection for more information.
HyperTransport Interconnect
The HT link is a packet-based link implemented on two unidirectional sets of signals. The link is
nominally point-to-point, and connects exactly two devices. Devices can have multiple HT links
to allow the construction of larger HT fabrics.
The HT link consists of a point to point x16 link (16 bits) that supports 6.4 GT/s per link in each
direction. The HT link is designed to deliver a scalable, high-performance interconnect between
CPUs and CPU to I/O devices.
Memory
The serverboard has 32 DIMM slots (eight per processor) that support DDR3-
1600/1333/1066/800 MHz DDR3 registered ECC SDRAM (see
“Installing Memory” on
page 37 ).
Serial ATA
A Serial ATA controller ASIC (AMD SP5100) is integrated into the system serverboard to
provide a six-port 3 Gb/s SATA subsystem. The hot-swappable SATA drives are connected to a
backplane that provides power, bus termination and configuration settings. RAID 0, 1, and 10 are
supported. Note that your operating system must have RAID support enabled to accommodate hot
swaping of disk drives. Check with your sales or service representative to obtain information on
set-up procedures if your system did not come pre-configured with SATA RAID.
