Description

The ExaNIC X4 also has built in port mirroring and bridging functionality, both useful features that are not available in other NICs. Additionally, with hardware–based time stamping of every packet to 6 nanoseconds resolution, users can rethink their approach to measurement and latency management.

The ExaNIC is also available in a two-port half-height version (ExaNIC X2); both cards share the same internal architecture and performance.
