Lowdown on the Latest PCI Updates

Lowdown on the Latest PCI Updates

PCIe technology, like its predecessor PCI, is a load/store architecture unlike any other open industry I/O standard. Devices based on the PCIe specification can be mapped directly into the system memory space, enabling them direct access to system memory, and promoting energy-efficient performance. Architected mechanisms define a consistent interface between software and hardware for essential system functions, including discovery, device driver association, and power management, to ensure seamless interoperability across multiple platforms and operating systems. Advanced error detection, recovery, and reporting mechanisms, in addition to hot-plug support, all meet the high reliability, availability, and serviceability (RAS) requirements of servers and storage segments. Further, scalable I/O subsystems can be built by exploiting the hierarchical architecture using switches.
