ExaLINK Hydra


The highest density layer 1 switch

The ExaLINK Hydra is the world's highest density layer 1 switch, and the first switch platform to use QSFP-DD connectors. Using 20x QSFP-DD connectors, the device supports up to 160x 10GbE lanes in a single rack unit (1RU). It is also available in a 36 port QSFP variant, supporting up to 144x 10GbE lanes in 1RU.

A layer 1 matrix switch is a powerful tool for tapping into connections (for network monitoring), patching connections between ports (for dynamic network reconfiguration) and fanning-out connections from one port to many (for low latency multicast).

ExaLINK Hydra Layer 1 devices operate at the (physical) electrical layer. No packet processing is performed on the critical path. This makes them incredibly fast. Average latencies through the device are under 7ns while minimum latencies are less than 3ns .

Despite operating at the physical layer, the devices are deeply packet aware. They provide rich packet statistics and monitoring on all ports, including packet counts, signal quality metrics and full packet dumps.

ExaLINK Hydra Layer 1 switches are a powerful and flexible component in any high performance network. Example use cases include:

The ExaLINK Hydra will soon be made available to selected customers on our early access evaluation program. Contact Exablaze sales to register for the program. General availability is expected in Q1 2019.
