DARWIN-S431CZ260026M

24x25Gb SFP28, 2x100Gb QSFP28 L3 Aggregation & Leaf Switch, Enterprise SONiC Ready, Macsec, VXLAN, BGP-EVPN

The DARWIN-S431CZ260026M is a 24×25G aggregation switch with 2×100G QSFP28 uplinks, powered by the Marvell Aldrin 3 chipset in a compact 1RU form factor. It delivers high throughput, dense connectivity, and operational efficiency in a sleek and space-saving design.

Running on AsterNOS, the commercial SONiC-based NOS, this Layer 3 switch offers a comprehensive feature set—from industry-standard routing protocols like OSPF and BGP to advanced capabilities such as VXLAN, BGP-EVPN, MLAG, and IPv6. Optional PTP and MPLS support enables deployment across diverse, high-performance, and time-sensitive applications.

Enterprise-Grade Security: With MACsec (Media Access Control Security), the DARWIN-S431CZ260026M delivers layer 2 encryption for secure, high-speed connectivity, protecting your campus or enterprise network from eavesdropping or tampering, all with minimal impact on performance.

In modern network architectures, the DARWIN-S431CZ260026M typically serves as a distribution/aggregation switch, but in small to mid-sized networks, it can also double as a cost-effective Top-of-Rack (ToR)/Leaf switch, providing a flexible and versatile solution for private clouds or compact data centers.
