Broadcom’s 25/50G Ethernet Controllers Extend End-to-End Data Center Portfolio

28 July 2015

The BCM57300 NetXtreme C-Series scalable 10G/25G/40G/50G Ethernet controller product family, according to Broadcom corporation, is the industry’s lowest power and smallest 25/50G solution for the cloud data center market.

Targeting the need for next-generation Ethernet controllers to accelerate the increased flow processing driven by virtualization, the new family delivers bidirectional 50G throughput with 30Mpps performance and the flow processing that data centers need to support higher virtual machine density.

When the NetXtreme C-Series controllers are used with the StrataXGS Tomahawk Ethernet Switch, they form a 25/50G end-to-end solution for data centers that delivers connectivity compliant with the Broadcom co-founded 25/50G Consortium and draft IEEE standard. The BCM57300 provides rapid, hardware-based, congestion notification responses that are 5,000x faster than traditional software-based approaches.

Benefits achieved from distributing the flow processing from the Top of Rack (ToR) and server host CPU into the NIC, include:

  • vSwitch Acceleration: TruFlow, an integrated flow processing engine, enables data center operators to move virtual switching from the host CPU into the Broadcom C-Series Controller, increasing available CPU cycles for application processing, and potentially increasing application performance up to 50%.
  • Flow Scalability: TruFlow distributes flow processing into the server endpoints, allowing data center growth without impacting network and application performance.
  • Software Defined Networking (SDN): TruFlow implements the fundamental SDN protocol constructs of classification/match/action processing in hardware, including the latest OpenFlow standard. Distributing SDN protocols into the BCM57300 lets cloud operators reap the benefits of SDN in their data centers.

Broadcom offers two families of standard adapter cards for customer deployment; PCIe NIC and OCP Mezzanine. Both adapter card families are based on the cloud-optimized BCM57300 NetXtreme C-Series of Ethernet controllers and are sampling now.
