Cornelis Networks provides the industry’s leading director class switch family.

Omni-Path Express Director Class Switches cost-effectively deliver high bandwidth and use advanced technologies to meet the key challenges to application performance, maximizing cluster scalability and message rate while minimizing average and tail latency.
Cornelis Omni-Path Express scale-out interconnect

Unprecedented demands on the scale-out interconnect are being driven by advances in artificial intelligence, high performance data analytics, and traditional modeling and simulation environments, coupled with extremely capable processing and storage infrastructures.

Cornelis Omni-Path Express is the next generation of high performance fabrics, a proven hardware foundation combined with the OpenFabrics Interfaces (OFI) software framework, that delivers the industry’s lowest latency, highest message rate, and best collectives performance, all at the industry’s lowest CPU utilization.

Accelerated application performance at scale

Cornelis Omni-Path Express Director Class Switches deliver full bidirectional bandwidth per port, providing up to 288 100 Gbps ports in 7U and up to 1152 ports in 20U.

Cornelis Omni-Path Express Director Class Switches are ideal for interconnecting mid-sized clusters and for providing the core of large clusters.

The Omni-Path Express Director Class Switches ensure optimal application performance by delivering key features for efficiency, including dynamic adaptive routing and congestion control. These features are complemented by a unique sub-link layer architecture that enables Packet Integrity Protection (zero latency protection against bit transmission errors) and Traffic Flow Optimization (pausing the transmission of a lower priority packet in favor of a higher priority packet).

These features, together with advanced Virtual Fabrics support, provide the unique interconnect capabilities to deliver industry-leading application performance and manageability at scale.
