What is the port configuration and switching capacity of DCS-7280SE-64-R?

It features 48x 10GbE SFP+ downlink ports and 4x 40GbE QSFP+ uplinks (configurable to 16x10GbE), delivering 3.2Tbps full-duplex switching capacity and 2.38Bpps forwarding rate. This supports non-blocking wire-speed across all ports for spine/leaf data center fabrics.

Does it support virtualization and overlay networking?

Yes, Arista EOS enables VXLAN bridging/routing (VRF, MLAG), VM Tracer for VMware integration, and 768K MAC/IPv6 routes. Ideal for multi-tenant clouds with seamless east-west traffic and network virtualization.

What management and monitoring features are available?

Includes CloudVision portal, Zero Touch Provisioning (ZTP), sFlow (RFC 3176), IEEE 1588 PTP, LANZ microburst detection, and DANZ mirroring. USB/RS-232 console, SNMPv3, and Syslog provide comprehensive visibility.

What airflow and power redundancy does it offer?

Rear-to-front airflow (DCS-7280SE-64-R) with redundant hot-swappable PSUs (2x included, C13-C14 cords). Energy-efficient design with environment monitoring reduces OpEx in dense deployments.

Is it suitable for low-latency applications like HFT?

Yes, virtual output queue architecture with deep buffers and cut-through switching delivers sub-microsecond latency. Supports PTP timing and precision monitoring for high-frequency trading and real-time apps.

What Layer 3 routing protocols are supported?

Full BGP, OSPF/OSPFv3, IS-IS, MP-BGP, RIPv2, static routes, and VRF. Scales to internet-scale routing with 768K host routes for large data centers and service provider edge.

Product overview

The Arista DCS-7280SE-64-R belongs to the 7280SE Series, purpose-built for demanding data center environments requiring ultra-low latency and high throughput. It features 48x 10GbE SFP+ ports and 4x 40GbE QSFP+ uplinks, delivering 3.2Tbps full-duplex switching capacity and 2.38 billion packets per second forwarding rate. Equipped with deep packet buffers up to 9GB (virtual output queue architecture), it eliminates head-of-line blocking for consistent performance under bursty traffic. Powered by Arista EOS, it supports advanced Layer 2/3 protocols including OSPF, BGP, VXLAN routing/bridging, sFlow, and IEEE 1588 PTP precision timing. Management includes CloudVision, ZTP, USB console, and RS-232 serial port. Rear-to-front airflow with redundant PSUs ensures reliability in spine/leaf topologies. Ideal for cloud-scale networking, virtualization overlays, high-frequency trading, and large-scale IP storage fabrics where scalability and monitoring are critical.
