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 support 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 Unified Fabric Manager™ (UFM™), SNMP V1,2,3, and web user interfaces. In addition, the SX1012 incorporates a familiar industrystandard CLI, which enables administrators to easily configure the switch.

To ensure long term applicability, the SX1012 is provisioned to enhance its current capabilities with additional L2 and L3 features through software upgrades.

World-Class Design

The SX1012 carries a unique design to accommodate the highest performance at a small form factor.

The unique design allows placement of two switches positioned side-by-side in a standard 19” rack to occupy 1RU height with high availability from the Network Interface Card level.

The SX1012 is available as reverse or forward airflow, allowing the switch to fit into data centers with different thermal designs and redundant power supplies and fans, providing yet another level of high availability for the application running within the pod.

Status LEDs for fans and power supply units are placed on both sides of the system for easy status identification. Quick start guide, rack mount kit, AC power cord and RJ45 console cable are provided as part of the standard system providing an easy out-of-the-box experience.
