The PEX 8696 is well suited for fan-out, aggregation, and peer-to-peer applications. Multi-Host Architecture The PEX 8696 employs an enhanced version of PLX’s field tested PEX 8648 PCIe switch architecture, which allows users to configure the device in legacy single-host mode or multi-host mode with up to eight host ports capable of 1+1 one active & one backup or N+1 N active & one backup host failover. This powerful architectural enhancement enables users to build PCIe based systems to support high-availability, failover, redundant and clustered systems. High Performance & Low Packet Latency The PEX 8696 architecture supports packet cut-thru with a maximum latency of 176ns 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. In addition to low latency, the device supports a packet payload size of up to 2048 bytes, enabling the user to achieve even higher throughput. Data Integrity The PEX 8696 provides end-to-end CRC ECRC protection and Poison bit support to enable designs that require end-to-end data integrity. PLX also supports data path parity and memory RAM error correction circuitry throughout the internal data paths as packets pass through the switch. Flexible Configuration The PEX 8696’s 24 ports can be configured to lane widths of x1, x2, x4, x8, or x16. Flexible buffer allocation, along with the device's flexible packet flow control, maximizes throughput for applications where PEX 8696 PEX 8696 more traffic flows in the downstream, rather than upstream, direction. Any port can be designated 23 x4 7 x8 8 x4 as the upstream port, which can be changed dynamically.
