What is the switching capacity and port configuration of HPE R3B06A SN2100M?

The SN2100M provides 3.2Tbps full-duplex switching capacity with 16 QSFP28 ports supporting 100/50/40/25/10/1GbE speeds. All ports allow x4 or x2 breakout for up to 64 ports, delivering 2.38Bpps forwarding with true wire-speed non-blocking performance across L2/L3.

Does the R3B06A support lossless Ethernet for storage protocols?

Yes, it features zero packet loss with NVMe TCP, RoCEv2 RDMA over L2/L3, DCBX, PFC, ECN. 16MB shared buffering prevents head-of-line blocking, ensuring reliable high-throughput for NVMe-oF and SMB Direct in storage fabrics.

What L3 routing protocols are supported on HPE SN2100M?

Full IPv4/v6 suite: OSPFv2/v3, BGPv4/v6, VRF with route leaking, ECMP resilient hashing, PIM-SM/SSM, policy-based routing, GRE tunneling, BFD for fast convergence, PTP boundary clock for precise timing.

How does the SN2100M design benefit data center rack density?

Unique 1RU form factor allows two switches side-by-side in a single rack slot, doubling to 6.4Tbps and 4.76Bpps. Connector-to-power airflow optimizes cooling for high-availability leaf/spine deployments.

Is the R3B06A compatible with ONIE and third-party NOS?

Yes, ONIE-enabled for installing Cumulus Linux or other open network OS. Ships ready for flexible deployment in disaggregated networks, supporting MLAG, EVPN-VXLAN with 6 bridges up to 1000 VNIs.

What power efficiency does the HPE SN2100M offer?

Under 6 watts per 100GbE port, significantly lower than competitors, reducing heat and OpEx. Provides full 100Gb/s wire-rate per port without performance throttling.

Product overview

The HPE R3B06A is the SN2100M 100GbE network switch, purpose-built for high-performance storage and data center environments. Featuring 16 QSFP28 ports supporting Ethernet speeds from 1GbE to 100GbE with breakout to 64x25GbE or x4 modes, it provides 3.2Tbps switching capacity and 2.38Bpps forwarding at wire-speed. Dual units fit side-by-side in 1RU for 6.4Tbps aggregated performance. Key benefits include ultra-low latency cut-through switching, zero packet loss with NVMe TCP and RoCEv2 RDMA support, DCBX, PFC, ECN for lossless fabrics. L3 routing with OSPF, BGP, VRF, ECMP, PIM, GRE tunneling, PTP. ONIE enables Cumulus Linux or other NOS for flexibility. 16MB shared buffering ensures no head-of-line blocking. Low power under 6W/port reduces OpEx. Ideal for leaf/spine topologies, AI/ML clusters, HPC, NVMe-oF storage networks demanding high throughput and reliability.
