Arista 7260X3 Series

The Arista 7260X3 Series is a 2RU high-density 100G switch delivering 12.8 Tbps of non-blocking switching across 64 QSFP28 100G ports, twice the 100G port density of the 1RU 7050X3 at the same ASIC latency profile. Two models address different use cases: the 7260CX3-64 (64x QSFP28 100G + 2x SFP+) targets dense leaf deployment where maximising the number of server connections per rack unit is the design priority, and the 7260CX3-40 (40x QSFP28 100G + 2x SFP+) targets compact spine and interconnect positions where 40 high-bandwidth ports are required with reduced physical footprint compared to a full 64-port model. Both operate below 1 µs forwarding latency.

Hardware table profiles match the 7050X3 family with selectable UFT allocation between MAC addresses, IPv4 LPM, and IPv6 LPM, supporting up to 128K MAC addresses, 64K IPv4 LPM routes, or a host-route-optimised profile with 64K IPv4 host routes. EVPN-VXLAN VTEP support, 32-way ECMP with 1K groups, and 256K IPv4 multicast (S,G) entries complete the L2/L3 feature set. Dual hot-swappable PSUs at 93% Platinum efficiency and N+1 redundant fans provide the availability baseline for a production switching tier.
