8749-8I/8748-8INVMe Series is PCI Express x16 Gen3 Multi-Host PCI-e switch Card. It offers Multi-Host PCI Express switching capability that enables users to connect multiple hosts to their respective endpoints via scalable, high-bandwidth, non-blocking interconnection to a wide variety of applications including servers, storage, communications, and graphics platforms. High Performance & Low Packet Latency The 8749-8I/8748-8I supports packet cut-thru with a maximum latency of 126ns (x16 to x16). This combined with large packet memory,flexible common buffer/FC credit pool and non-blocking internal switch architecture, provides full line rate on all ports for performance-hungry applications such as servers and switch fabrics. The low latency enables applications to achieve high throughput and performance and supports a packet payload size of up to 2048 bytes, enabling the user to achieve even higher throughput.
