HPE R3B04A SN2745M Connector Airflow Ethernet Switch 32 Ports

The HPE R3B04A is a high-performance 100 Gigabit Ethernet switch from the SN2745M series, meticulously engineered to address the demanding throughput and low-latency requirements of modern data centers, high-performance computing, and enterprise storage environments. This switch is designed to deliver predictable and consistent throughput, crucial for critical applications where any packet loss can severely impact operations and application performance. It solves the challenge of escalating data volumes by providing robust, non-blocking network infrastructure. Architecturally, the R3B04A features 32 QSFP28 ports, each capable of supporting 100 Gigabit Ethernet. Through the use of breakout cables, these ports can also flexibly operate at 10, 25, 40, or 50 Gigabit Ethernet speeds, allowing for a phased transition and broad compatibility with existing infrastructure while preparing for future growth. With a formidable switching capacity of 6.4 Terabits per second and an exceptionally low latency of just 300 nanoseconds, this device ensures data flows at wire speed, mitigating bottlenecks and accelerating application response times in virtualized and hyperconverged environments. Deployment of the HPE R3B04A is streamlined thanks to its compact 1U rack-mountable form factor, ideal for efficient Top-of-Rack (ToR) deployments within dense data center racks. Its "Power to Connector Airflow" design optimizes cooling efficiency in hot-aisle/cold-aisle configurations. For enhanced operational resilience and uptime, the switch incorporates two hot-swappable, 1+1 redundant power supplies. Management is versatile, supporting both industry-standard Command Line Interface (CLI) and graphical user interfaces (GUI), alongside Open Network Install Environment (ONIE) for flexible operating system deployment.
