1-2 Chipset Overview
The H8DSL-HTi serverboard is based on the ServerWorks HT-1000 (HyperTrans-
port
TM
SystemI/O
TM
hub) chipset. The HT-1000 chipset provides high performance,
scalability and reliability. Its HyperTransport architecture reduces IO bottlenecks to
improve overall system performance. System memory controllers are integrated
into the processors to decrease latency.
HT-1000 HyperTransport I/O Hub
The HT-1000 I/O hub interconnects the processors with the I/O bridge via a Hyper-
Transport bus to provide an interface between the various subsystems including
the I/O functions, SATA subsystem, the onboard graphics, the IDE controller and
the USB ports.
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 effi cient use of memory in
multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.
