Gen 4 PCIe switches support hyperscale computing advances

To support cloud, data centre and hyperscale computing advances in artificial intelligence (AI) and machine learning (ML), Microchip Technology has released the Switchtec PAX Advanced Fabric Gen 4 PCIe switch family. The devices enable complex fabric topologies with greater scalability, lower latency, and higher performance than traditional PCIe switches, claims the company.

The Switchtec PAX PCIe family of switches are designed to reduce time to market for systems requiring multi-host sharing of single root I/O virtualisation (SR-IOV) non-volatile memory (NVMe) solid state drives (SSDs), graphics processing units (GPUs) and other PCIe endpoints.

According to Microchip, they are industry’s lowest-power Gen 4 PCIe switches, “significantly” reducing total system power consumption. The Switchtec PAX family of switches is available as 100-lane, 84-lane, 68-lane, 52-lane, 36-lane and 28-lane variants.

Applications include GPU workstations, composable general purpose GPUs (GP-GPUs) fabrics, scalable multi-host systems, SR-IOV-enabled just a bunch of flash (JBOF), disaggregated systems and rack-scale architectures.

Microchip Technology provides smart, connected and secure embedded control solutions. It says its development tools and product portfolio enable customers to create optimal designs which reduce risk while lowering total system cost and time to market. Customers are in the industrial, automotive, consumer, aerospace and defence, communications and computing markets.

The company is headquartered in Chandler, Arizona, USA.
