Exablaze is now part of Cisco.

Superseded Notice

The ExaNIC X10 product is fully superseded by the ExaNIC X25 which has lower latency 10GbE performance, and 25GbE upgrade capability.

New projects are strongly encouraged to consider the ExaNIC X25 over the ExaNIC X10.

ExaNIC X10


Exablaze's ExaNIC X10 is an ultra low latency network interface card which delivers the lowest latency in the industry: 780ns 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 X10 also has built in bridging functionality which allows it to function as a miniature switch, avoiding the extra latency of a switch in some common use cases. Additionally, with hardware-based time stamping of every packet to 6 nanoseconds resolution, users can rethink their approach to measurement and latency management.

The card features an SMA connector which can accept a PPS in or drive PPS out to further improve the accuracy of timestamps taken throughout the system.

The second port can be configured to mirror a copy of all traffic coming into port 1, and/or all traffic leaving port 1 (as well as operating as a normal port itself). Additionally, bridging mode allows packets to pass quickly between the 2 ports via the FPGA (i.e. without involving the host).
