Detailed Specifications
HPE R3B05-63001 SN2745M 100GbE 32-Port QSFP28 Switch
Overview
The HPE R3B05-63001 is a high-density 1U rack-mount switch engineered for data-centre spine-or-leaf fabrics, delivering 32 QSFP28 ports each capable of 100 Gb/s throughput. With an aggregate non-blocking switching capacity of 6.4 Tb/s, it supports full-line-rate forwarding across all ports and accommodates breakout configurations into 50/40/25/10 Gb/s speeds. The switch features a "power-to-connector" airflow design optimized for modern hot-aisle/cold-aisle data-centre cooling, dual hot-swappable power supplies and fans for redundancy, and open-networking readiness via ONIE bootloader. It is suited to high-performance computing, hyperscale cloud, storage-fabric or large-scale deployment environments where ultra-low latency, high throughput and flexible speed optics are vital.
