Description
The Supermicro H8DGi-F serverboard is based on the AMD Dual SR5690 and one SP5100 chipset. This chipset functions as a Media and Communications Processor (MCP).
Controllers for the system memory are integrated directly into AMD Opteron processors.
AMD SR5690/SP5100 Chipset
The AMD Dual SR5690 and one SP5100 are each a single-chip, high-performance
HyperTransport peripheral controller. It includes a 42-lane PCI Express interface, an
AMD Opteron 16-bit Hyper Transport interface link, a six-port Serial ATA interface
and an eight-port USB 2.0 interface. This hub connects directly to the CPU.
HyperTransport Technology
HyperTransport technology is a high-speed, low latency point to point link that was
designed to increase the communication speed by a factor of up to 48x between integrated circuits. This is done partly by reducing the number of buses in the chipset to reduce bottlenecks and by enabling a more efficient use of memory
in multi-processor systems. The end result is a significant increase in bandwidth within the chipset.
