7368X4 Series | Platform Overview

Model Overview

The Arista 7368X4 is a high performance system that enables up to 32 ports of 400G, 128 ports of 100G, or up to 128 ports of 25G in a

compact 4RU system with 8 interface module slots. The 7368X4 delivers 12.8 Tbps of system forwarding and up to 8 Bpps with a single

high capacity packet processor in a con gurable system. The system is designed for exible con gurations with a choice of interface

module cards, ease of maintenance operations for cloud networks, increased network scale and resilience with advanced tra c

management and congestion control.

The 7368X4 delivers high performance, with feature rich layer 2 and layer 3 forwarding, suited for both leaf or spine deployment in

modern large scale networks, addressing the challenges of increasing network capacity and e ciency through lower power, enhanced

automation and advances in scalability.

The 7368X4 is designed around the 7368X4 switch card (7368X4-SC), that is fully connected to 8 I/O module slots delivering 3.2 Tbps of

system capacity to each slot. The management module runs Arista Extensible Operating System (EOS) on a quad core CPU with 32GB

of memory with the performance to run the control plane and management functions of the system. The removable interface

modules provide for mix and match of interface types and density including 25G, 100G, 200G and 400G with each module supporting

a range of interface speeds using industry standard optics and cables. Each IO module connects directly to the switch card without

adding any oversubscription. All components of the system including the switch card are removable for ease of maintenance and

simplifying upgrades.

The system supports up to 4 high e ciency AC or DC power supplies, providing su cient power for both current and future needs,

with both grid and power supply redundancy and are hot-swappable to eliminate downtime when replacing power supplies. High

performance fan modules deliver resilient data center optimized system cooling in both forward and reverse air ow directions.

The Arista 7368X4 series switches support port to port latency as low as 700 ns in cut-through mode, and a 64 MB packet bu er with a

large shared pool allowing for superior burst absorption compared to multi-chip systems or pre-allocated xed per-port bu ering.
