7280R High Availability
The Arista 7280R switches were designed for continuous operations with system wide monitoring of both hardware and software
components, simple serviceability and provisioning to prevent single points of failure. Key high availability features include:
- 1+1 hot-swappable power supplies and four hot-swap fans provide dynamic temperature control combined with N+1 redundancy
- Color coded PSU’s and fans that deliver platinum level power efficiency
- Self healing software with Stateful Fault Repair (SFR)


Maximum Network Design Flexibility
- Scalable designs with up to a 128-way ECMP provides flexibility and balances traffic evenly across the largest leaf-spine designs
- MLAG designs are effective at almost any layer of the network and maximize cross-sectional bandwidth with fast failover times measured in 100’s of milliseconds for link failures.
- VXLAN gateway, bridging and routing with VMTracer features to enable next generation data center designs
- Scaleable routing tables to support internet route peering
- Wide choice of dense 10G/40G/100G interfaces with broad support for flexible 10GbE, 25GbE or 50GbE modes.
- Support for standards based IEEE 25GbE with mix and match support for both 10G and 25G for simple and cost effective migration
- Virtual output queue (VoQ) architecture and deep packet buffering to eliminate head of line blocking with low latency
- ACL scalability with up to 24K entries per forwarding engine allows for rich policy control
- Flexible allocation of L2 and L3 forwarding table resources for more design choice
- PTP, sFlow, DANZ and multi-port mirroring tools provide network wide visibility and monitoring to detect traffic bursts, monitor latency and congestion and allow capacity planning to improve application performance and availability

7280R Accelerated sFlow
SFlow is a powerful tool used commonly by network operators for advanced network telemetry, capacity planning, security analysis and
quality of experience monitoring. All models of the 7280R Series enable sFlow utilizing the high performance CPU. Within modern high
performance systems traffic sampling requires the capability to both sample and process packet rates of hundreds of millions of
packets per second. With the 7280R Series Accelerated sFlow feature the sampling and processing of flow samples into sFlow
datagrams is handled via a dedicated sFlow engine capable of generating up to 1.6Mpps of sFlow data, and of supporting 1:1000
sampling rates of full wire speed systems or higher rates with selective sampling based on triggers and filters. All sFlow v5 information is
included in the sFlow records ensuring consistent integration with existing standard sFlow collection and analysis tools and no loss of
information.

7280R Deterministic Network Performance
The Arista 7280R Series uses a deep buffer virtual output queue (VOQ) architecture that eliminates head-of-line (HOL) blocking and
virtually eliminates packet drops even in the most congested network scenarios. An advanced traffic scheduler fairly allocates
bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, fixed
priority, or hybrid schemes. As a result, the Arista 7280 can handle the most demanding data center requirements with ease, including
mixed traffic loads of real-time, multicast, and storage traffic while still delivering low latency
