Last year, Open Compute Project (OCP) launched a new network project focused on developing operating system agnostic switches to address the need for a highly efficient and cost effective open switch platform. Mellanox Technologies collaborated with Cumulus Networks and the OCP community to define unified and open drivers for the OCP switch hardware platforms. As a result, any software provider can now deliver a networking operating system to the open switch specifications on top of the Open Network Install Environment (ONIE) boot loader.
At the upcoming OCP Summit, Mellanox will present recent technical advances such as loading Net-OS on an x86 system with ONIE, OCP platform control using Linux sysfs calls, full L2 and L3 Open Ethernet Switch API, and also demonstrate Open SwitchX SDK. To support this, Mellanox developed SX1024-OCP, a SwitchX®-2-based TOR switch which supports 48 10GbE SFP+ ports and up to 12 40GbE QSFP ports.
The SX1024-OCP enables non-blocking connectivity within the OCP’s Open Rack and 1.92Tb/s throughput. Alternatively, it can enable 60 10GbE server ports when using QSFP+ to SFP+ breakout cables to increase rack efficiency for less bandwidth demanding applications.
Mellanox also introduced SX1036-OCP, a SwitchX-2-based spine switch, which supports 36 40GbE QSFP ports. The SX1036-OCP enables non-blocking connectivity between the racks. These open source switches are the first switches on the market to support ONIE over x86 dual core processors.
