Arista 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.

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 standards-based overlay
controller solutions.

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
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.
!

Arista 7280R Flexible Combinations
The Arista 7280R lowers total cost of ownership as they are designed to be efficient with power per port as low as 25W per 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.
