Message Text: Chipmaker LSI is hoping to improve networking performance with its ARM-based Axxia 4500 processor family, announced Monday.

LSI is hoping that the ARM-based processors, which typically power smartphones and tablets, are capable of also powering next-generation switches and routers for enterprises.

Axxia 4500 is LSI?s first ARM technology-based communication processor family designed for enterprise and datacenter networking applications as well as evolving Software Defined Networks (SDN).

By combining LSI networking accelerators and Virtual Pipeline technology with ARM?s power-efficient cores and scalable interconnect, the new Axxia processors are designed to address the performance challenges facing next-generation networks.

The new processors include up to four ARM Cortex-A15 cores with a CoreLink CCN-504 coherent, QoS aware interconnect in 28nm process technology. The addition of LSI Virtual Pipeline technology allows equipment developers the ability to essentially reconfigure the processors for optimal performance on a packet-by-packet basis. The Axxia 4500 processors also include up to 100Gb/s of L2 switching function to reduce board space and bill of material costs.

A key challenge facing many datacenter network managers is the fast emergence of SDN. SDN will require high levels of secure communication between SDN controllers and network elements such as switches and routers. LSI claims that Axxia packet processing and security accelerators are suited to process secure communications for SDN protocols like OpenFlow.

LSI will begin sampling the Axxia 4500 in Q4. The company is showing off its networking portfolio at the Open Networking Summit, which takes place between April 15 and 17 in Santa Clara.
