ExaNIC X40

LOW LATENCY 10/40GBE NETWORK INTERFACE CARD

Exablaze's ExaNIC X40 is a high density network interface card featuring incredibly low latency: 800ns application to application for small Ethernet frames (using the native API) and under a microsecond for small TCP and UDP payloads (using the transparent socket acceleration library).

The ExaNIC X40 ships with firmware providing eight 10GbE interfaces on a host, and through the use of QSFP+ breakout cables can connect to eight SFP+ ports. This enables a range of high performance applications such as packet capture across multiple connections, or market data line arbitration across many different feeds.

An alternate firmware image is available for download that provides two 40GbE interfaces. Users are free to switch between firmware images depending on their requirements.

As with our other NICs, the ExaNIC X40 provides hardware-based time stamping to a resolution of 6.2 nanoseconds. The card features an SMA connector which can accept a pulse-per-second (PPS) in or drive PPS out to further improve the accuracy of timestamps taken throughout the system.
