OVERVIEW

The UfiSpace S9311-64D is a next-generation, ultra-high-density data center networking white box switch that is designed to address the exponential bandwidth demands of hyperscale data centers and AI/ML fabrics and the need to push network capacity and scale to the next level.
With 64 x 400GE QSFP-DD ports, the S9311-64D data center switch acts as a high-capacity aggregation point, ideal for interconnecting large clusters of high-performance compute and storage resources with non-blocking, line-rate Ethernet connectivity.
This switch delivers an incredible 25.6 Tbps of throughput in a power-efficient 2RU form factor, helping operators to increase rack density while managing operational expenses like power and cooling.
The S9311-64D provides the foundation for next-generation networks with its powerful Tomahawk 4 processor and 64 high-speed 400GE interfaces. It is built for mission-critical reliability, featuring 1+1 hot-swappable power supplies and 3+1 redundant fans for maximum uptime, simplified serviceability, and enhanced operational stability.
