Frequently Asked Questions

What are the primary port configurations and interface types available on the Arista DCS-7280SE-64-R? +

The Arista DCS-7280SE-64-R is a high-performance, fixed-configuration switch designed for data center environments. It features 48 SFP+ ports capable of 1/10GbE connectivity, alongside 4 QSFP+ ports that support 40GbE uplinks. This port density and flexible interface configuration make it an excellent choice for spine-leaf architectures or high-bandwidth server aggregation requirements in enterprise networking environments.

How does the Arista DCS-7280SE-64-R handle deep buffer requirements in modern data centers? +

This switch is engineered with a deep packet buffer architecture, significantly outperforming standard shallow-buffer switches. The large buffers effectively handle bursty traffic patterns and congestion common in high-density virtualized environments or storage area networks, preventing packet loss and ensuring consistent performance for latency-sensitive applications even during periods of heavy network load.

What is the physical airflow design of the DCS-7280SE-64-R and how should it be deployed? +

The 'R' designation in the model name specifies a rear-to-front airflow configuration. This design is optimized for data centers utilizing hot-aisle/cold-aisle containment systems. When deploying this unit, ensure the intake side is positioned in the hot aisle and the exhaust faces the cold aisle to maintain proper thermal regulation and peak operational efficiency for the internal components.

Which Arista EOS features are supported on the DCS-7280SE-64-R for network management? +

As a member of the 7280 series, this switch runs the Arista Extensible Operating System (EOS). This allows for full programmability, comprehensive automation capabilities through APIs like eAPI, and advanced monitoring features like LANZ (Latency Analyzer). It supports standard L2 and L3 routing protocols, providing enterprise-grade stability, visibility, and integration with modern cloud-based orchestration tools.

Can the DCS-7280SE-64-R be used for VXLAN routing in a leaf-spine architecture? +

Yes, this platform is specifically designed to support hardware-based VXLAN routing and bridging. It functions effectively as a leaf switch in a VXLAN overlay network, enabling seamless connectivity between virtual machines across different subnets. The deep buffers and high-performance ASIC allow for efficient encapsulation and decapsulation without compromising the throughput required for modern virtualized workloads.

What are the power supply redundancies supported by the Arista DCS-7280SE-64-R? +

The switch is equipped with redundant, hot-swappable power supply units to ensure maximum uptime and system availability. This modular approach allows for seamless maintenance or replacement of power units without interrupting network traffic. We recommend configuring the switch with dual power sources connected to separate circuit breakers to maintain true hardware-level redundancy in mission-critical environments.

Is the DCS-7280SE-64-R suitable for high-frequency trading or low-latency financial applications? +

While the 7280 series excels in deep-buffer scenarios, it also provides excellent deterministic latency characteristics for enterprise applications. It is widely used in high-performance computing environments where reliable throughput and packet integrity are paramount. For specific financial deployments, the internal queuing mechanisms and congestion management features provide the necessary performance profile for demanding, data-intensive trading traffic flows.

Does the DCS-7280SE-64-R support standard rack-mounting in a 19-inch cabinet? +

The unit is designed as a 1U rack-mount device, making it fully compatible with standard 19-inch server racks. The chassis includes necessary hardware for secure mounting within a standard data center rack enclosure. When installing, ensure there is adequate clearance in the rear and front to facilitate the rear-to-front airflow, which is critical for maintaining the optimal operating temperature of the switch.
