Mellanox has an answer to Cisco, Arista

Data center switch maker Mellanox Technologies this week unveiled a new processor designed to optimize its switches for software-defined networking (SDN).

The company's SwitchX-2 processor includes capabilities such as remote configurable routing tables, support for overlay networks, and SDN-optimized software interfaces. SwitchX-2 is intended to enable IT managers to program and centralize their server and storage interconnect management and virtualize their data center network.

Citing data from IDC, Mellanox says the SDN/OpenFlow market is expected to reach $2 billion by 2016.

SwitchX-2 is based on Mellanox's Virtual Protocol Interconnect technology, which is designed to allow simultaneous connection to InfiniBand or Ethernet with integrated gateways to legacy data center and storage systems. Utilizing RDMA-based 56Gbps Ethernet and InfiniBand, SwitchX-2 features 4Tbps switching capacity, 170 nanosecond latency, hardware-based L2/L3 congestion management and hardware-based data error correction to enable the creation of large, flat SDN networks.

Cisco recently rolled out a switch designed to lower latency to 190 ns for high-frequency trading environments. This switch is expected to compete with InfiniBand/Ethernet offerings from Mellanox, as well as Ethernet switches from Arista. Arista itself recently unveiled its lowest-latency switch, the 7150S, which is also expected to face stiff competition from Cisco's Nexus 3548 and those from Mellanox using the new SwitchX-2.

Mellanox said SwitchX-2 will begin emerging in its SwitchX-based Ethernet and InfiniBand switches toward the end of the year.
