Product Review

The Arista DCS-7504N-CH offers high performance with a maximum throughput of 38 Tbps and 17.3 billion packets per second, catering to demanding networking environments. However, its considerable size (7RU) and weight (up to 222 lbs when fully equipped) may limit installation options in space-constrained racks. The flexibility in power supply (AC or DC) and comprehensive redundancy features (5+1 redundancy, N+1 fan module, and N+N grid redundant power system) ensure reliability and adaptability in various operational conditions.


The Arista DCS-7504N-CH is a high-performance modular switch designed for data center networks, offering flexibility, scalability, and a comprehensive range of networking features. This product is built to cater to the increasing demands of modern data centers, providing high-density Ethernet connectivity, low latency, and high throughput. At the heart of the Arista DCS-7504N-CH are 2 supervisor slots and 4 line card slots, complemented by 6 fabric slots. This configuration ensures ample room for expansion and customization, allowing network administrators to tailor the system to their specific needs. The chassis supports both AC and DC power supplies, which must be ordered separately, offering versatility in power management. With 4 power supply slots, the system ensures a redundant power supply, enhancing reliability and uptime. The physical dimensions of the chassis stand at 12.25 inches in height, 19 inches in width, and 31.3 inches in depth, occupying 7 rack units (RU) in a standard server rack. When empty, the chassis weighs 76.5 lbs (34.7 kg), while a fully equipped system reaches a weight of 222 lbs (101 kg), showcasing its substantial build quality and capacity for extensive hardware integration.
  • Maximum 10GbE and 25GbE port density is 576 ports each, providing extensive connectivity options for high-speed networking.
  • For higher bandwidth requirements, it supports up to 144 40GbE ports, 288 50GbE ports, and 144 100GbE ports, catering to diverse network architectures and data throughput needs.
  • The maximum throughput capability of the system reaches 38 Tbps, with a packet processing capacity of up to 17.3 billion packets per second (Bpps), highlighting its exceptional performance in data-intensive environments.
The system's maximum power consumption is rated at 5,640W, indicating its efficiency and capability to manage energy use effectively, even at full operational capacity. Designed to operate reliably in a wide range of environmental conditions, the Arista DCS-7504N-CH can function in temperatures from 0 to 40˚C (32 to 104˚F) and be stored in temperatures ranging from -40 to 70˚C (-40 to 158˚F). Humidity tolerance ranges from a minimum of 5% to a maximum of 95%, non-condensing, ensuring stability in various climatic conditions. The operational altitude extends up to 10,000 feet (0-3,000m), offering flexibility for installation in different geographic locations. Redundancy is a critical feature of the Arista DCS-7504N-CH, with a 5+1 redundancy scheme for its fan modules and an N+N grid redundant power system, ensuring continuous operation and minimal downtime. This redundancy, coupled with its high port density and throughput capabilities, makes the Arista DCS-7504N-CH an ideal solution for enterprises and service providers seeking a reliable, scalable, and high-performing networking platform for their data center infrastructure.
