Frequently Asked Questions
What are the primary port configurations for the Arista DCS-7280SR3-48YC8-R? +
The DCS-7280SR3-48YC8-R is a high-density fixed-configuration switch designed for deep buffer requirements. It features 48 ports of 25GbE SFP28, which also support 10GbE speeds, alongside 8 ports of 100GbE QSFP28. This combination provides the necessary flexibility for both high-bandwidth spine connectivity and flexible server edge access in modern data center environments.
What is the primary use case for the Arista 7280SR3 series in a data center? +
This switch is engineered for demanding environments that require deep packet buffering, such as cloud data centers, high-performance storage networks, and content delivery networks. Its architecture is specifically optimized for traffic bursts and large-scale data flows that require consistent, low-latency performance without packet loss, making it an ideal choice for spine-leaf or leaf-switch roles.
Does the Arista DCS-7280SR3-48YC8-R support advanced network virtualization features? +
Yes, this model runs on Arista EOS, which includes robust support for advanced virtualization technologies. It natively supports VXLAN routing and bridging, enabling seamless Layer 2 and Layer 3 segmentation across the physical network. This functionality is essential for building scalable software-defined data centers where multi-tenancy and network agility are critical requirements.
How does the airflow design work on this specific Arista switch model? +
The 'R' suffix in the DCS-7280SR3-48YC8-R model designation indicates a rear-to-front (port-side intake) airflow configuration. This design is specifically tailored for standard cold-aisle/hot-aisle data center rack layouts, ensuring that the switch intake pulls cool air from the cold aisle to maintain optimal thermal operating temperatures for the internal components during high-performance operation.
Is the DCS-7280SR3-48YC8-R compatible with Arista CloudVision? +
Absolutely. This switch is fully compatible with Arista CloudVision, which provides a comprehensive platform for network-wide automation, telemetry, and visibility. By integrating this switch into a CloudVision-managed environment, operators can simplify provisioning, streamline configuration management, and gain deep insights into network health, which significantly reduces the operational overhead associated with managing complex high-density fabrics.
What layer 3 routing capabilities does the 7280SR3 platform provide? +
The platform offers a powerful suite of Layer 3 routing protocols, including BGP, OSPF, and IS-IS, alongside support for static routing and policy-based routing. These features, combined with the large deep-buffer memory, allow the switch to handle massive routing tables and complex traffic patterns efficiently, ensuring stability and performance for large-scale enterprise and cloud-scale IP routing deployments.
How is power redundancy managed for the DCS-7280SR3-48YC8-R? +
This unit is designed for high availability, featuring dual, field-replaceable power supply modules. It supports both AC and DC power options depending on the installed modules. These power supplies are hot-swappable and operate in a redundant configuration, ensuring that the switch remains operational and maintainable even in the event of a single power source or supply failure.
What are the physical dimensions and rack space requirements for this switch? +
The DCS-7280SR3-48YC8-R is housed in a standard 1U form factor rackmount chassis. Its design is optimized for high-density environments where rack space is at a premium. With its compact 1U footprint, it delivers exceptional port density, allowing data center managers to maximize throughput per rack unit without compromising on the deep buffer capabilities required for modern applications.
