Microsemi Announces New Switchtec PAX Advanced Fabric PCIe Switch to Accelerate Evolution of Hyperconverged Systems to Composable/Disaggregated Infrastructures



Microsemi Corp., a provider of semiconductor solutions differentiated by power, security, reliability and performance, announced the availability of its Switchtec PAX advanced fabric Gen3 PCIe switch providing high-performance fabric connectivity for scalable, multi-host systems and just a bunch of flash (JBOF) supporting single root input/output (I/O) virtualization (SR-IOV), NVMe and multi-function endpoints.

Hyperconverged systems are evolving towards composable/disaggregated infrastructures (C/DI) such as rack scale architecture to meet the rapidly changing demands on resources and storage capacity of next-generation applications. PAX advanced fabric PCIe switches provide a scalable, low latency and cost-effective solution to the disaggregation of computing, networking, graphics processing units (GPUs) and storage resources. These PAX PCIe switches, which are flexibly interconnected with configurable high-speed fabric links, virtualize PCIe domains and SR-IOV endpoints. System development is simplified through a fabric application programming interface (API) and the ability to utilize off-the-shelf NVMe host drivers, significantly reducing time-to-market for complex multi-host systems.

According to market research firm IDC’s February report, “Composable/Disaggregated Infrastructure (C/DI)—Addressable Market Opportunity,” the total worldwide addressable opportunity for vendors with C/DI is $34.5 billion in 2017. The firm also expects this opportunity will grow at a modest compound annual growth rate (CAGR) of 7.4 percent and reach $45 billion in 2020. Microsemi’s Switchtec PAX advanced fabric PCIe switch is well-aligned to these growth trends, as it enables customers to leverage the device for the development of next-generation C/DIs.

Microsemi’s Switchtec PAX family comprises switches from 96 lanes to 24 lanes, providing:
• High-performance PCIe fabric connectivity overcoming the limitations of the PCIe Specification for rack scale multi-host systems
• Multi-host sharing of SR-IOV and multifunction endpoints
• Virtualization of PCIe domains and SR-IOV NVMe solid state drives (SSDs)
• Software development kit (SDK) for virtualization of other SR-IOV endpoints, and for enclosure management
• The most flexible port bifurcation in the industry, from x2 to x16 lanes per port
• The highest port density, with up to 48 ports
• Advanced error reporting
• Error containment for surprise-plug and unplug to prevent system crashes
• Advanced diagnostics and debug features to identify, diagnose and fix problems
• Separate Refclk Independent SSC (SRIS) for cabled PCIe and lower cost system designs
