PCI Express* Technology, Enterprise Serial Innovation
Paper: Overview -- The PCI Express* architecture is the next-generation local I/O interconnect for the compute and communications industries. In this article, hardware developers will learn about trends in enterprise interconnect technologies, including storage, networking, and clustering, and how PCI Express can provide a common host connection attach point for all of them through a 2.5 GHz serial interface. They also will learn about how and why PCI Express can provide significant performance, cost, and scalability advantages as compared to traditional parallel PCI designs.
Trends in enterprise interconnect technologies -- For a decade now, PCI has provided a successful general-purpose I/O interconnect standard. Today, however, there’s an increasing need for a new perspective for a general-purpose interconnect, one that can surpass the scalability limits inherent in multidrop, parallel-bus implementations and provide a unified serial attach point. This need is driven by dramatic innovations in computing, communications, and data center technologies, including CPU speeds of 10 GHz and beyond, interconnects running at 10 Gbps and higher, and applications that require more and more bandwidth in the highly distributed environment of corporate data centers.
InfiniBand architecture is emerging as the industry’s first de facto clustering standard in the high-performance computing (HPC) space. With initial link speeds of 10 Gbps, InfiniBand architecture is the first industry-standard interconnect to offer Remote Direct Memory Access (RDMA) to server clusters. Major evaluations of this technology are due this year from Intel-sponsored evaluations at such institutions as Los Alamos Labs. Early success in the HPC arena is laying a foundation for InfiniBand implementations focused on database clustering.
