Based on Microchip PCIe Switchtec technology, the MXH910 host adapter includes advanced features for non-transparent bridging (NTB ) and comes with a full license to the Dolphin eXpressWare software.
The MXH910 host adapter combines 64 Gbit/s performance with less than one microsecond latency, significantly improving overall inter-system communication. Inter-processor communication applications benefit from the high throughput and low latency.
The MXH910 supports both Remote Direct Memory Access (RDMA) and Programmed IO (PIO) transfers, effectively supporting both large and small data packets. RDMA transfers result in efficient larger packet transfers and processor off-load. PIO transfers optimize small packet transfers at the lowest latency. The combination of RDMA and PIO creates a highly potent data transfer system.
Dolphin’s eXpressWare software suite takes advantage of PCI Express’ RDMA and PIO data transfer scheme. Delivering a complete deployment environment for customized and standardized applications. The suite includes a Shared-Memory Cluster Interconnect (SISCI) API as well as a TCP/IP driver and SuperSockets software. The SISCI API is a robust and powerful shared memory programming environment. The TCP/IP driver and SuperSockets™ software remove traditional networking bottlenecks, allowing standard IP and sockets applications to take advantage of the high performance PCI Express interconnect without modification. The overall framework is designed for rapid development of inter-processor communication applications.
The MXH910 is carefully designed for maximum cable length and support copper cables up to 5 meters at full PCI Express Gen3 speed when connected to another MXH910 card. More information on cables for the MXH910.
