Arista 7280R Series Universal Leaf and IP Storage Networks

Designed for next-generation IP storage, Content Delivery, leaf and spine networks and Data Center Interconnect the Arista 7280R Series fixed-configuration switches combine dynamic and deep buffering for lossless forwarding with high density, internet scale table sizes, and comprehensive L2 and L3 features. Advanced EOS features for network monitoring; precision timing, VXLAN network virtualization, and rich automation are combined with extensive hardware resources. A choice of density and interface types allows the 7280R to meet the address of the myriad different applications and traffic patterns found in modern data centers.

 

Arista 7280R Advantages:

• Unparalleled Performance with Dynamic Deep Buffers and VOQ for Lossless forwarding
• Flexible design choices for 10G/25G/40G/50G and 100G
• Arista FlexRoute™ and EOS NetDB™ for internet peering with high density and low power
• Arista AlgoMatch™ for flexible and scalable network policy control
• Accelerated sFlow for high capacity network security and application monitoring
• EOS Open Programmability for Advanced Traffic Control, Provisioning, and Monitoring

 

 

 

The Arista 7280R Series FlexRoute engine and EOS NetDB provide the scalability to support the Internet IP routing scale with the lowest power consumption and fast convergence while scaling to millions of routes.

Arista AlgoMatch™ enables more flexible access controls with expanded scale across more fields with full capacity while providing additional capabilities for filtering. AlgoMatch is also the enabler for increased network telemetry using sFlow to sample traffic at hundreds of gigabits per second per system.

Arista 7280R Series Technical Specifications

 

The Arista 7280R Series is a set of purpose-built 10/25/40/50/100G fixed configuration 1RU and 2RU systems designed for the highest performance environments such as IP Storage, Content Delivery Networks, Data Center Interconnect, and IP Peering. Wire-speed L2 and L3 forwarding are combined with advanced features for network virtualization, open monitoring and network analysis, resiliency, and architectural flexibility with deterministic performance. Deep packet buffers and large routing tables allow for Internet peering applications and the broad range of interfaces and density choice provides deployment flexibility.

The Arista 7280R Series FlexRoute™ engine provides the scalability to support deployment as a routing platform with Internet scale routing. Arista FlexRoute along with EOS NetDB™ enables innovations and convergence not natively available in merchant chipsets.

 

7280R Benefits

 

• Standards-based high-density 100G switch ideal for future proof designs and high bandwidth needs such as in High-Performance Storage or Content Delivery Networks (CDNs)
• Dynamic deep buffers in a fixed form factor make for an ideal top of rack 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 PTP enables accurate timing solutions across Ethernet-based networks without costly investment in separate timing networks
• Unique monitoring and provisioning features – LANZ, DANZ, AEM, IEEE 1588 PTP, ZTP, VM Tracer, VXLAN, and eAPI
• Comprehensive L2 and L3 feature set for open multi-vendor networks with no proprietary lock-in
• Large scale L2 and L3 table resources allow deployment flexibility in both large L2 and L3 environments with any-workload suitability
• NEBS compliance and DC power supplies designed for service provider environments
