Arista Extensible Operating System (EOS)
All Arista products including the 7280R Series runs the same Arista EOS software, binary image simplifying network administration
with a single standard across all switches. 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 together with stateful
switchover without the loss of data plane forwarding.
Arista EOS enables advanced monitoring and automation capabilities such as Zero Touch Provisioning, LANZ, VM Tracer and Linux
based tools to be run natively on the switch.
Software Defined Cloud Networks
Arista Software Defined Cloud Networking (SDCN), combines the principles that have made cloud computing the unstoppable force
that it is: automation, self service provisioning, and linear scaling of both performance and economics coupled with the trend in
Software Defined Networking that delivers: network virtualization, custom programmability, simplified architectures, and lower
capital expenditure. This combination creates a best-in-class software foundation for maximizing the value of the network to both
the enterprise and service provider data center. A new architecture for the most mission-critical location within the IT infrastructure
that simplifies management and provisioning, speeds up service delivery, lowers costs and creates opportunities for competitive
differentiation, while putting control and visibility back in the hands of the network and systems administrators.
The Four Pillars of Arista's Software Defined Cloud Networking:

Scaling Data Center Performance
The Arista 7280R Series deliver non-blocking switching capacity that enables dramatically faster and simpler network designs for
data centers and lowers both capital and operational expenses. The Arista 7000 Series of fixed and modular systems with a single
consistent EOS allows for flexible selections at all tiers of the network and deployment scenarios including layer 2 MLAG, layer 3
ECMP, VXLAN Overlay, and Internet Peering.
Arista’s Multi-Chassis Link Aggregation (MLAG) technology supports a leaf and spine active/active L2 network topology. An Equal
Cost Multi-Path (ECMP) design at Layer 3 scales the network in a fully non-blocking, low-latency, two-stage network that provides
predictable and consistent application performance. The flexibility of the L2 and L3 multi-path design options combined with
support for open standards provides maximum flexibility, scalability and network wide virtualization that scales to hundreds of
thousands of hosts in a single two-tier design. Both designs support overlay networks via VXLAN and can integrate with standardsbased overlay controller solutions.
The Arista 7280R Series FlexRoute engine provides the flexible scalability to support deployment as a routing platform with
Internet scale routing. Arista FlexRoute along with EOS NetDB enables innovation not natively available in merchant chipsets. Arista
EOS provides operational savings through visibility, automation and improved network operations.

Enhanced Features for High Performance Cloud Networks
The Arista 7280R delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high
performance environments, with solutions for automation, data monitoring, precise timing and next-generation virtualization.
Automating the data center enables customers to dynamically provision computing resources in the most efficient manner while
also meeting business needs by maintaining service level agreements (SLAs). Arista EOS automates complex IT workflows and
simplifies network operations while reducing or even eliminating downtime. Arista EOS rich automation capabilities not only reduce
the human error element in network operations but also enable IT operators to make the network work the way they want.
Arista offers solutions for a variety of approaches to cloud-like network automation. Addressing the needs of the largest public
cloud environments as well as applying those lessons learned in the turnkey CloudVision automation offering.
CloudVision
CloudVision is a network-wide approach for workload orchestration and workflow automation as a turnkey solution for Cloud
Networking. CloudVision extends the EOS publish subscribe architectural approach across the network for state, topology,
monitoring and visibility. This enables enterprises to move to cloud-class automation without needing any significant internal
development.
Arista Event Management (AEM)
Advanced Event Management (AEM), a sub-system of Arista EOS, is a powerful and flexible tool to automate tasks and customize
the behavior of EOS and the operation of the overall data center switching infrastructure. Simplifying the overall operations, AEM
provides the tools to customize alerts and actions. AEM allows operators to fully utilize the intelligence within EOS to respond to
real-time events, automate routine tasks, and automate actions based on changing network conditions.
Precise Data Analysis
Page 3
QuickSpecs
Arista 7280R Data Center Switch Router Series
Overview
Arista Latency Analyzer (LANZ) and Precision Data Analyzer (DANZ) are integrated features of EOS. DANZ provides a solution to
monitoring and visibility challenges at 10/40/100Gbps giving IT operations the ability to proactively deliver feedback on
congestion events, filter, replicate, aggregate and capture traffic without affecting production performance. LANZ provides precise
real-time monitoring of micro-burst and congestion events before they impact applications, with the ability to identify the sources
and capture affected traffic for analysis.
Precision Timing (IEEE 1588)
Arista’s hardware derived Precision Time Protocol solution provides a robust mechanism for accurate in-band time distribution in
high performance environments. The system clock can be synchronized using the Supervisor module clock input port with a PPS
source or IEEE 1588 PTP.
Virtualization
Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation
technologies such as VXLAN. The 7280R builds on the valuable tools already provided by the Arista VM Tracer suite to integrate
directly into encapsulated environments. Offering a wire-speed gateway between VXLAN and traditional L2/3 environments, the
7280R makes integration of non-VXLAN aware devices including servers, firewalls and load-balancers seamless and provides the
ability to leverage VXLAN as a standards based L2 extension technology for non-MPLS environments.

100GbE port which combined with front to rear cooling to optimize the data center environment produces the most reliable, dense
and power efficient 100GbE fixed configuration switch.
7280R Deterministic Network Performance
The Arista 7280 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.
