Tomahawk II 64-port 100 Gb/s 2 RU switch introduced March 2017. Build on a single PCB. Design contributed to OCP. Note that there is a model number change between the OCP submission and appearance of the data sheet. 7800 became 7816.
Edge-core has a data sheet as of January 18, 2018. This might mean that these are now headed for the distribution pipeline rather than being merely asperational. World-wide distributors and resellers are listed on their web page. As of March 11, 2018, we are looking for confirmation on supplier web pages that the product is available.
