Maximum Network Design Flexibility

• Scalable designs with up to a 128-way ECMP provides exibility and balances tra c evenly across the largest leaf-spine designs

• MLAG designs are e ective 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 exible 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 e ective migration

• Virtual output queue (VoQ) architecture and deep packet bu ering 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 tra c 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 tra c 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 ow 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 lters. 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 bu er 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 tra c scheduler fairly allocates

bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, xed

priority, or hybrid schemes. As a result, the Arista 7280 can handle the most demanding data center requirements with ease, including

mixed tra c loads of real-time, multicast, and storage tra c while still delivering low latency.

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 e ciency

• Live software patching

• Self healing software with Stateful Fault Repair (SFR)

• Smart System Upgrade (SSU) and Accelerated Software Update (ASU)
