Cisco Nexus 3232C
Introduced in multiple trade press articles on June 10, 2015. Expected to start shipping 3rd Quarter 2015. Note that the ports are QSFP28 rather than proprietary CPAK. That is because this is a whitebox switch running Cisco software. It seems to be a consensus in the trade press community that this is a Tomahawk switch. The data sheet lists buffer memory on page 5. 16 MBytes of packet buffers matches the Tomahawk hypothesis.
