Product Description
The Sun PCI High Speed Quad Port Serial Interface adapter is high-speed serial
interface (HSI) adapter for PCI applications and is referred to as the SunHSI/U™
adapter in this manual. The adapter offers comprehensive hot-plug compatibility
with Solstice™ WAN software packages available through Sun. The SunHSI™
software is a transparent interface on the SunHSI/U adapter, providing a compliant
environment for SunLink™ WAN packages operating on similar Sun communication
modules.
The SunHSI/U adapter (see
FIGURE 1-1
) is an intelligent, four-port communication
controller with onboard CPU and memory dedicated to WAN communication
functions. This architecture operates much more efficiently at high data rates than
unintelligent WAN modules. Onboard intelligence allows the workstation or server
to be off-loaded from many of the low-level communication tasks that it must
perform when there is no native intelligence on the controller.
