High-speed data movement interconnect specialist Inphi Corporation and provider of switch silicon for datacentres Innovium are partnering to provide customers with multiple, highly scalable 100G to 400G datacentre solutions.High-speed data movement interconnect specialist Inphi Corporation and provider of switch silicon for datacentres Innovium are partnering to provide customers with multiple, highly scalable 100G to 400G datacentre solutions.

These solutions include:

• Reference design for a 128 x 100 GbE switch system, which features Innovium’s TERALYNX™ 12.8 Tbits/s single-chip programmable switch with PAM4 IO with Inphi’s Vega™ gearbox, to offer the highest radix fixed switch with 128 ports of 100GbE to connect using the existing NRZ-based copper and optics ecosystem. This system is designed to dramatically reduce complexity, power, latency and cost compared to existing solutions that use multiple 3.2 or 6.4 Tbits/s switch chips.

• A highly scalable comprehensive switch plus optics solution for customers with compelling economics, power efficiency and performance. Innovium TERALYNX™ has been developed to enable customers to build compelling switch configurations such as 128 ports of 100 GbE, 64 ports of 200 GbE or 32 ports of 400 GbE. Inphi’s Polaris™ and Porrima™ family provides optics module vendors PAM4 technology to build highly power efficient, cost-effective and high performance 100 GbE, 200 GbE and 400 GbE optics modules.

“Inphi has a range of proven PAM4-based power efficient DSP PHY ICs, drivers and TIAs in its Polaris™ and Porrima™ family to enable time to market next-gen 100 GbE, 200 GbE and 400 GbE optics with significant cost/bit advantage,” states Inphi SVP, Networking Interconnects, Siddharth Sheth. “Further, it leverages its PAM4 expertise to offer a very compelling gearbox solution in its Vega™ family to bridge connectivity between Innovium’s 12.8 Tbits/s switch based on PAM4 interfaces and the large install base of NRZ-based copper and optics ecosystem.”

The partners note that, according to Cisco’s 2018 Global Cloud Index, there is a secular trend towards large scale datacentres, where the number of sites is expected to double by 2021, and traffic within such establishments is expected to quadruple over that same period. Datacentre customers are therefore looking at multiple ways to scale their networks while driving operational efficiencies and investment protection. They are trying to flatten their networks with larger radix fixed switches to reduce tiers in the network, deploy higher performance 12.8 Tbits/s switches in the network to scale bandwidth, increase power efficiency and adopt higher speed 200/400G connectivity with lower cost.
