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 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 to 100G
- Arista FlexRoute™ and EOS NetDB™ for internet peering with high density and low power
- EOS Open Programmability for Advanced Traffic Control, Provisioning and Monitoring
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 makes 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 25GbE, 40GbE and 50GbE 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
