Palo Alto Networks and Arista Solution Brief

The relentless rise of traffic levels across data networks has created a challenge for even the most high-performance security devices. To tackle these ever-changing and demanding traffic profiles, Arista Networks and Palo Alto Networks have partnered to deliver unique solutions for enterprises. This brief will give a high-level overview of the partnership between Arista and Palo Alto Networks and a symmetric scaling solution to increase firewall capacity.


Arista Scale with Symmetry Guide

Arista Networks has partnered with Palo Alto Networks to help our customers scale to the performance demands on their networks. While the initial goal was to build a 100 Gbps firewall cluster, the actual solution scale is only limited by the physical number of ports on the switch and can be used by any network-based appliance. Leveraging the extensibility built into every Arista Extensible Modular Operating System (EOS)TM, the Arista OpenFlow Direct Mode, and the unique deployment options offered by the Palo Alto Networks virtual-wire mode, we are able to deliver scale while ensuring flow symmetry.

Arista OpenStack Integration

The Arista OpenStack solution automates the provisioning of VLANs on Arista switches to work in concert with the OVS plugin. This is in contrast to the other OpenStack plugins available today, which allow deployment of either the virtual switch plugin or the hardware device plugin, but not both. The architecture implemented is open and vendor agnostic.Providing this capability within the OpenStack solution is a significant achievement for integration with physical network devices. The availability of the drivers published back into the OpenStack community by Arista Networks can lead to truly multi-vendor solutions for VLAN provisioning automation within OpenStack environments.


Advanced Monitoring and TAP Aggregation

Arista DANZ on the 7150 platform enables scalable end-to-end monitoring directly integrated into the data path, or as a more traditional dedicated observation network. At the core of these capabilities are advanced monitoring, TAP aggregation, and precision time stamping. A rich management API complements these core capabilities, as well as precision time synchronization enabling precision large scale captures and direct integration with open and enterprise application analysis tools. This tech note will expound upon core capabilities of advanced monitoring, aggregation, and time stamping, demonstrating how they can be utilized to remove some of the traditional analysis bottlenecks and design constraints.


Arista Precision Time Protocol

Until now, data center class switches have not provided a hardware based PTP implementation. This has limited the scale and precision of PTP implementations by requiring dedicated PTP hardware at every point, essentially minimizing the benefit of a common infrastructure for both data forwarding and time synchronizations. This document will review how the Arista 7150 data center switch enables high precision time distribution directly in the data path, while improving the scale, precision, and cost of a precise time infrastructure.


VXLAN: Eliminating Cloud Boundaries with SDN

Arista, in partnership with EMC® Isilon®, F5 Networks and VMware, demonstrate SDN technology innovations to support multi-vendor programmatic automation between their respective systems. This capability enables end-to-end network virtualization from physical, to virtual, to cloud networks.  Arista and VMware are co-authors of a new standard in virtual networking, called Virtual eXtensible LAN (VXLAN), that has created a common network foundation that enables seamless interoperability across diverse topologies.  Utilizing VXLAN in combination with API interaction between ecosystem partners and Arista’s Extensible Operating System (EOS), VMware, Arista, F5 and Isilon are demonstrating a fully automated, software defined Data Center environment.


VXLAN Bridges Virtual and Physical Networks to the Cloud

A new network technology developed by Arista and VMware that enables stateful VM mobility, within the data center beyond L3 boundaries. This increases the agility of applications and enables workloads to be deployed to better meet the business needs.


Media & Entertainment Solution Guide

Media and entertainment companies are realizing that they not only have to consolidate their IT into a common infrastructure, manage storage more effectively, and better utilize computing assets, but they also have to reduce the number of different technologies that are deployed to simplify operational challenges and reduce costs. The foundation of this transformation is a high-speed switched networking infrastructure that allows many different end point systems to be connected reliably, efficiently, and at scale.


Arista Advanced Event Management

Traditional methods have served the static data center well in the past, but with the movement toward the virtualized cloud, an event driven service model is needed. Arista Networks solves these challenges by leveraging the power of Arista’s Extensible Operating System (EOS), providing a unique set of tools to help directly address the challenge of advanced event management.
