20Gb/s interconnect devices target data centre apps
Integrated Device Technology Inc. (IDT) has revealed that its 20Gb/s RapidIO interconnect devices are used in Prodrive Technology's motherboards based on the RapidIO Trade Association's data center standard specification released in 4Q13. According to the firm, the switch products offer 100ns latency, energy efficiency and multi-processor scalability, promising advanced performance in data center and supercomputing analytics applications.
IDT's RapidIO switches and bridges serve as the on-board and inter-board interconnect for data center compute and networking (DCCN) motherboards developed by Prodrive. The RTA-compliant motherboards come in a 19in form factor with up to four computing daughtercards, supporting a variety of processing nodes from x86, to ARM, DSP, FPGA and PowerPC. Using the DCCN motherboard, OEMs, data center operators, supercomputing centers and financial trading organizations can develop high-throughput, low-latency computing systems ideal for high performance analytics applications. The DCCN platform will be submitted by the RTA to industry organizations such as the Open Compute Project (OCP) in 1H14.
IDT's RapidIO switches offer robust fault tolerance and hot-swap support, built-in reliable transmission, and non-blocking switch performance. Energy-efficient system designs can take advantage of RapidIO's 300mW per 10Gb/s of data, the highest power to performance ratio compared to other interconnects. In addition, IDT's RapidIO-to-PCIe bridge provides connectivity to the PCIe-based network interface controller's functionality, while consuming only 2W at 20Gb/s, indicated IDT. This allows for high-density solutions within the DCCN platform using x86-based daughtercards. RTA-compliant systems can be scaled up to 64K nodes with RapidIO 20Gb/s interconnection between DCCN motherboards. They can also be aggregated with 10 Gigabit Ethernet interfacing to many commercially-available Ethernet top-of rack-switches.
