HPER0P82A

SN2100M Managed switch100 GbE - 16 × QSFP28 Ports

The HPER0P82A (also known as the SN2100M switch) is a high-performance, half-width 1U Ethernet switch offering 16 QSFP28 ports capable of running at 100 Gbps, as well as supporting 1/10/25/40/50 GbE speeds via breakout or mixed optics. Built for modern data centers, flash storage fabrics, and hyperconverged environments, it delivers wire-speed switching across varying packet sizes, cut-through forwarding latency of ~300 ns, and predictable throughput even under mixed loads. The switch supports Layer 3 Managed switchrouting, MLAG, and VLAN segmentation, making it ideal as a Top-of-Rack (ToR) switch in demanding server and storage network deployments. Its side-by-side half-width design enables two devices in a single rack unit for high port density and redundancy

Features

The SN2100M Series includes the R0P82A model with 16 QSFP28 ports, each supporting native 100 GbE or breakouts to dual 50G, quad 25G, or 4×10/1 GbE depending on cabling and optics. Its non-blocking 3.2 Tb/s switching fabric enables up to 4.76 Bpps packet forwarding when two switches are deployed side-by-side in the same 1U space. Latency remains extremely low (~300 ns), making this switch ideal for high-density, low-latency environments.Supported layers include full L3 protocols×OSPF, BGP, VRF, multicast, and MLAG for active-active redundancy. SN2100M supports QoS, ACLs, VXLAN, and segmentation×enabling performance-sensitive multi-tenancy and secure overlay deployment. It integrates via CLI or RESTful APIs, with optional support for network automation and programmability.Two SN2100M units can be mounted side-by-side in standard 1 RU racks for dual-redundant ToR deployments, effectively expanding port density to 32 QSFP28 ports in 1U space. Power consumption is modest (~94 W per switch) even under full load, making it efficient in power-constrained environments.

Advanced Options

The SN2100M switch features wire-speed packet forwarding with no performance drop across packet sizes, enabling consistent throughput and service delivery. Latency remains in the sub-microsecond range (~300 ns), making it suitable for latency-sensitive storage (e.g. NVMe over Fabrics), high-frequency trading, or AI clusters.Redundancy is enabled by side-by-side design: two SN2100M devices fit in a single 1U rack space, offering active duplicates for high availability and dual-ToR redundancy. Dual internal power supplies, efficient heat dissipation, and low AC draw (~94 W) support dense deployment with minimal thermal and power impact.
