Mellanox Technologies MSX1012B-2BFS Managed L3 1U Black network switch

Managed, 40GbE, 12xQSFP, 1U Mellanox MSX1012B-2BFS SwitchX-2 Based 40GbE 12 QSFP+ Ports
The SX1012 switch system provides the highest-performing top-of-rack (ToR) solution in a half-width 1U form factor by delivering up to 1.3Tb/s of non-blocking throughput with 10GbE or 40/56GbE form factor.

The SX1012 is the ideal top-of-rack (ToR) switch for small pods connecting a small number of servers with 40GbE. Each QSFP port can be used with a passive breakout cable to create four discrete SFP+ interfaces to be used as 10GbE ports, for a total of 48-ports on the smallest form factor 10GbE ToR in the industry.
