What port configurations does the HPE R3B03A SN2700M support?

The 32 QSFP28 ports offer flexible configurations: 32x40/100GbE native, 32x50GbE, or 64x10/25GbE using breakout cables. This versatility supports diverse server/storage connections in data centers, with full wire-speed non-blocking performance across all modes.

What is the switching performance of this HPE switch?

It delivers 6.4Tbps switching capacity and 4.76 billion packets per second forwarding rate with 300ns latency. The 16MB packet buffer handles microbursts effectively, making it suitable for high-density ToR/spine roles in cloud and HPC environments.

Does the R3B03A support open networking standards?

Yes, ONIE (Open Network Install Environment) pre-installed enables loading third-party NOS like Cumulus, SONiC, or OPX. This provides operator choice and reduces vendor lock-in for large-scale data center deployments.

What management interfaces are available?

Includes 2x RJ45 1GbE management ports, 1x RJ45 serial console, and 1x USB port. Layer-3 managed features support advanced routing, QoS, and telemetry for enterprise-grade network operations.

What redundancy features does it offer?

1+1 hot-swappable power supplies in connector-to-power DC airflow configuration, plus 4x N+1 hot-swap fans. These ensure high availability with minimal downtime in mission-critical data center fabrics.

What is the power consumption profile?

Typical power draw is 150W, optimized for energy efficiency in dense 100GbE deployments. Redundant PSUs support high MTBF for reliable operation without excessive cooling requirements.
