New Gen 4 PCIe switches provide 16 GT/s speeds for machine learning, data center servers and storage markets

Not surprisingly, PCIe (Peripheral Component Interconnect Express) is a high-performance industry standard interface that is widely deployed in data centers to transform their speed and performance.

To drive the deployment of PCIe solutions, Microsemi is sampling availability of its Switchtec Gen 4 PCIe switches. The products will help customers to build next-generation high performance, low latency interconnect solutions in high growth markets including machine learning, data center servers and storage equipment, according to the company.

New PCIe switches claim low latency, low power and high-reliability


The new generation of PCIe switches claims to offer high density and reliability as well as low power.

Microsemi says it also provides customers a quick time to market solution with field-proven Switchtec firmware and a chip architecture enabling significant re-use of customers’ investments in Switchtec management software, drivers, firmware and system design.

“Server, storage and general-purpose graphics processing unit (GPGPU) architectures are increasingly growing their use of PCIe infrastructure and our new Switchtec Gen 4 PCIe switches provide a high-reliability solution to address this increasing demand,” said Andrew Dieckmann, vice president of marketing and applications engineering for Microsemi’s Data Center Solutions business unit.

The Switchtec Gen 4 PCIe switches are GPU-optimized with low pin-to-pin latency and low latency variation for optimal machine learning workload performance.

Other features include up to 100 line-rate capable PCIe lanes as well as an integrated high-performance cut-through direct memory access (DMA) engine.

High-reliability features include hot- and surprise-plug support, end-to-end data integrity and best-in-class debugging with the ChipLink diagnostics tool.
