Arista 7280R3 Series Network Switch - Quick Look

Arista 7280R3 Series Introduction

The Arista 7280R3 Series are a key component of the Arista 7000 Series portfolio and consist of 7280R3 and 7280R3K products. The Arista 7280R3 Series is a set of purpose built 25G/100G/400G fixed configuration systems designed for the highest performance environments, where wire speed L2 and L3 forwarding are combined with advanced features for network virtualization, open monitoring and network analysis, resiliency and architectural flexibility. The 7280R3 Series capabilities address the requirements for modern networking and rich multimedia where content delivery require a lossless forwarding solution.

The Arista 7280R3 Series FlexRoute engine provides the flexible scalability to support deployment as a routing platform with Internet scale routing. All Arista 7280R3 Series support FlexRoute™ engines providing the scalability to support deployment as a routing platform with Internet scale. The 7280R3 Series Accelerated sFlow feature samples and processes flow samples at linerate. The 7280R3K Series support a series of flexible profiles that leverage common resources for different network roles including up to 5M IP routes. Algorithmic ACLs enable more flexible and scalable solutions for access control, policy based forwarding and network telemetry, available on the Arista 7280R3 and 7280R3K series.

7280R3 Advantages

• Standards-based high density 100G and 400G switch ideal for future proof designs and high bandwidth needs such as in Internet Exchanges, High Performance Storage or Content Delivery Networks (CDNs).
• Intelligent deep buffers in a fixed form factor makes an ideal spine switch where lossless performance and in-cast problems are expected such as in data analytics and IP storage.
• Directly connected 25G, 40G and 50G attached storage systems, requiring high performance and predictable latency.
• Streaming network state for advanced analytics with CloudVision.
• Network–wide virtualization platform for next generation cloud bursting with wire-speed VXLAN routing
• Hardware assisted IEEE 1588 and SyncE enables accurate timing solutions across Ethernet based networks without costly investment in separate timing networks
• Unique monitoring and provisioning features – LANZ, DANZ, AEM, ZTP, VM Tracer, VXLAN, and eAPI
• Comprehensive L2 and L3 feature set for open multi-vendor networks with no proprietary lock-in.
• Accelerated sFlow and IPFIX for network forensics.
• Scalable forwarding table resources allow deployment flexibility in both large L2 and L3 environments for emerging network workloads.
• Programmable packet processor for advanced features and flexible profiles enabling different use cases including peering and DCI.
• NEBS compliance and DC power supplies designed for service provider environments.
• Flexible support for 100G, 200G and 400G with wide selection of optics and cables including OSFP and QSFP-DD form factors.
• Comprehensive interface combinations with 50G and 200G modes on both 400G and 100G ports using optics and cables.
• Segment Routing and EVPN with flexible options for underlay and overlay topologies.

Arista EOS

Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.
