7280R3A Series Data Center Switch - Quick Look

Arista 7280R3A Series Introduction

The Arista 7280R3A Series of fixed systems are the latest generation of Arista 7000 Series portfolio of data center switches. The 7280R3A Series are purpose built 100G and 400G systems built for the highest performance environments, and to meet the needs of the largest scale data centers and service providers. They deliver scalable L2 and L3 resources, high bandwidth encryption and high density with advanced features for network monitoring, precision timing and network virtualization to deliver scalable and deterministic network performance while simplifying designs and reducing Opex.

The 7280R3A’s capabilities address the requirements for modern networking and rich multi-media content delivery requiring a lossless forwarding solution in a compact and energy efficient form factor, offering rich functionality for traditional data centre, virtualized/overlay networking and wide area networking along with deep packet buffers, large routing tables and industry leading switching capacity. For maximum flexibility, each platform provides a choice of three levels of scale and functionality with Standard (R3A), Encryption (R3AM) and Large Scale plus Encryption (R3AK) models available.

All Arista 7280R3A Series support FlexRoute™ engines providing the scalability to support deployment as a routing platform with Internet scale. The 7280R3A Series Accelerated sFlow feature samples and processes flow samples at linerate. The 7280R3AK Series support a series of flexible profiles that leverage common resources for different network roles including over 5M IP routes. Algorithmic ACLs enable more flexible and scalable solutions for access control, policy based forwarding and network telemetry, available on the Arista 7280R3AK series.

7280R3A 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 50G, 100G and 200G attached storage systems, requiring high performance and predictable latency
• Comprehensive, wire-speed, cloud data center virtualization and carrier routing with EVPN-VXLAN, MPLS and Segment Routing
• Line rate TunnelSec encryption for strong layer 2 and layer 3 security
• Hardware assisted IEEE 1588 and SyncE enables accurate timing solutions across Ethernet based networks without costly investment in separate timing networks
• Streaming network state for advanced analytics with CloudVision
• Unique monitoring and provisioning features – LANZ, DANZ, AEM, ZTP, 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 10G, 25G, 40G, 50G, 100G, 200G and 400G with wide selection of optics and cables including OSFP, QSFP-DD and QSFP form factors

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.
