Description

This fabric module is a required component of the 4-slot Arista 7304 chassis in the 7300X3 Series of modular data centre switches. It provides the switching fabric between line cards and has integrated fans with front-to-rear airflow. It suits leaf/spine and spline designs, collapsed data centre tiers, campus roles and large-scale east-west traffic networks where low latency matters.

The module is built for the DCS-7304X3 chassis, which has four fabric slots, and fabric slots 1-4 must be populated. Typical power draw is 191W, with a maximum of 288W per module. It measures 11.80 x 3.70 x 10.27 inches (30 x 9.4 x 26.1 cm) and weighs 10.3 lbs (4.7 kg). Fabric modules are redundant and hot-swappable, with graceful degradation if a module is lost. Across the 7304X3 chassis, fabric throughput reaches 25.6 Tbps and 16 Bpps. The system runs Arista EOS.

The module works with the 7300X3 line cards DCS-7300X3-32C-LC, DCS-7300X3-48YC4-LC and DCS-7300X3-48TC4-LC, and the supervisors DCS-7300-SUPE and DCS-7300-SUP2-D. The 8-slot equivalent is DCS-7308X3-FM-F.
