Omni-Path 100G 48-port switch

High Performance, High Density, Low latency, 100-Gigabit Omni-Path Architecture, Meets the Most Demanding Application for HPC

Supermicro SSH-C48Q 1U 48-port top-of-rack network switch products supports the 100Gbps Intel® Omni-Path Architecture (OPA) providing a unique HPC cluster solution offering excellent bandwidth, latency and message rate that is highly scalable and easily serviceable.

SSH-C48Q products 48-port 100Gbps supporting Omni-Path Architecture leverages the Intel Scalable System Framework (SSF) to address evolving demands across high performance data analytics, machine learning, visualization, traditional modeling and simulation workloads. Designed specifically for HPC, the 48-port SSH-C48Q products offer 9.6 Tb/s total fabric bandwidth. High scalability with the capability of 27,648 nodes in 2-tier configuration. Supermicro SSH-C48Q products are designed to overcome the scaling challenges of large-sized clusters. The enhancements include:

High Message Rate Throughput. The SSH-C48Q products are designed to support high message rate traffic from each node through the fabric. That means the fabric can support the high bandwidth as well as high message rate throughput associated with the ever-increasing processing power and core counts of Intel® Xeon® Processor and Intel® Xeon Phi coprocessors.

48-port Switch ASIC. With a 48-port design the SSH-C48Q products provide improved fabric scalability, reduced latency, increased density, reduced cost, and lower power demand. It is the basis of the SSH-C48Q products capacity of 9.6 Tb/s fabric bandwidth and high scalability to 27,648 nodes in 2-tier configurations.

Deterministic Latency. Features in the Intel OPA optimize the performance impacts of large Maximum Transmission Units (MTUs) on small messages. They help maintain consistent latency for inter-process communication (IPC) messages, such as Message Passing Interface (MPI) messages, when large messages-typically storage-are being simultaneously transmitted in the fabric. Intel® OPA can bypass lower priority large packets, giving higher priority to small packets, creating a lower and more predictable latency through the fabric.

Enhanced End-to-End Reliability. The Supermicro SSH-C48Q products also deliver its own unique error detection and correction which is more efficient than the forward error correction (FEC) defined in the InfiniBand standard. Enhancements include zero load for detection - if a correction is required, packets only need to be retransmitted from the last link-not all the way from the sending node. This gives near-zero additional latency.
