Mellanox SX1012 Switch System - 12 Port, 40/56G Ethernet - 40/56G Ethernet 12-Port Switch

The Mellanox SX1012 SDN switch system provides the highest-performing top-of-rack (ToR) solution in a half-width 1U form factor by delivering up to 672Gb/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.

The SX1012 switch has a rich set of networking and application performance features that excel and enable Software Defined Networking in any data center, making this switch the perfect solution for your network. 

SwitchX®-2 carries a unique design that enables users with a straight forward platform for implementation of a Software Defined Network, allowing the construction of a high scale network with advanced fine tuning control plane capabilities. The SX1012 supports the Virtual Protocol Interconnect® (VPI) technology which enables it to be used for both Ethernet and InfiniBand technology providing the user with flexibility and investment protection. The SX1012 provides a full suite of management options, including support for Mellanox’s NEO™, SNMP V1,2,3, and web user interfaces. In addition, the SX1012 incorporates a familiar industry-standard CLI, which enables administrators to easily configure the switch.
