November 4th, 2015

by Nick Lippis, Lippis Report Testing

In this Lippis Test Report we measure end-to-end performance for a data center interconnect (DCI) solution that included Infinera and Arista network equipment. A key take-away from this experience working with Infinera’s Cloud Xpress optical transport platform and Arista’s 7280SE-68 programmable switches it’s that high-performance, high-capacity DCI – at multiples of 100 Gb/s with line-rate throughput and low latency – is feasible and straight forward to deploy. Based on our test results and my observations, Infinera and Arista have engineered impressive products and a solid end-to-end solution that address enterprises that require DCI with high speed, low latency and low power consumption.

April 1st, 2014

By Arista Networks

Performance, resiliency and programmability across the entire network are now fundamental business requirements for next generation cloud and enterprise data center networks. Arista Networks has designed and delivered EOS (Extensible Operating System), a Linux-based network operating system, to address these requirements. EOS is a robust, programmable and innovative system, featuring a single software image that runs across the entire portfolio of Arista’s network switches. This guarantees consistent operations, workflow automation and high availability, while significantly reducing data center operational expenses. This whitepaper discusses current network operating systems and explains how Arista’s EOS architecture uniquely supports next generation data centers.

By Lippis Enterprises

Arista 7500E is the most widely deployed spine switch of this new class of 288 40GbE modular switches. Over the past few months, the Lippis Report with Ixia tested the 7500E for layer 2 and 3 unicast plus multicast performance, congestion management, demanding cloud traffic performance, power consumption, the ability for its VOQ buffers to be adjustable, and if its 64-Way ECMP hash works as advertised as well as performance tested its 100GbE Line Card. If you’re building a cloud network, then you need to read this report first. In this report, we deliver the most comprehensive test and review of Arista’s 7500E modular data center spine switch.

Palo Alto Networks and Arista Networks have partnered to offer the highest performance next-generation
firewall implementation in the industry. The modern data center has ever-increasing demands for throughput and performance, and the security infrastructure required to protect and segment the network must be able to meet those demands. The combination of Arista Networks’ Datacenter Switches along with Palo Alto Networks’ next-generation firewalls provides unmatched security in high-performance data centers without impacting throughput.

AgilePorts over DWDM for long distance 40GbE

Get the White Paper

January 27th, 2014

By Arista Networks

Existing 40GbE solutions are limited to 10km and require costly upgrades to DWDM systems to enable long haul extensions. The AgilePorts feature enables groups of adjacent SFP+ ports to be configured for 40Gb operation using 10Gb transceivers and cables providing maximum port flexibility and a seamless migration from 10Gb to 40Gb. This enables the use of inexpensive and simple 10Gb DWDM systems to extend a 40GbE service. Arista AgilePorts allows four 10GbE SFP+ to be combined into a single 40GbE interface for easy migration to 40GbE.

BIG DATA BECOMING A COMMON PROBLEM
IDC projects that the digital universe will reach 40 zetabytes (ZB) by 2020, an amount that exceeds previous forecasts by 5 ZBs, resulting in a 50-fold growth from the beginning of 2010. With an ever-increasing amount of this data being unstructured it is changing the fundamental ways in which we manage and extract value from data. The term unstructured data refers to information that either does not have a pre-defined data model and/or does not fit well into relational tables. Generally it is text-heavy, but may contain other data such as dates, numbers, etc. This data comprises what is more commonly known as big data. In the past the ability to process big data was proprietary and expensive, with few people who knew how to deal with it. Mobility, social networking and search data all comes in as unstructured and needs some form of big data analytics to help increase its value. For many this means using big data analytics on the front-end and putting the data once sorted and processed into traditional relational databases on the backend – but without some preprocessing this is not possible and large amounts of relevant information are lost.

Arista is committed to supporting big data clusters in the way they were designed to operate with a non-blocking, deep buffered, high-speed data center network. This coupled with Arista’s EOS, the world’s most advanced network operating system, allows best-in-class native integration with popular big data distributions such as Hadoop.

IP Ethernet Storage

January 27th, 2014

By Arista Networks

Traditional storage networks and costs are growing at an exponential rate. New requirements for compliance and new applications such as analytics mean that ever-increasing volumes of unstructured data are collected and archived. Legacy storage networks cannot meet the need to scale- out capacity and reduce capital and operational expenditures. In response to this challenge, new storage architectures based on Ethernet have evolved. How will this change the storage network? Most future IT asset deployments will leverage 10 10GbE and 40GbE for the underlying storage interconnect for newer applications. Arista Networks has responded to the need for a new
IP Ethernet storage fabric. Arista provides industry- leading products and solutions that deliver operational and infrastructure efficiencies that have been previously unavailable.

by Arista Networks

As 10 and 40GbE data center networks provide very low latency with less than 10ns of jitter and favorable price points, the ability to converge storage and user traffic onto one physical network has become realistic. In this white paper, Arista details various cloud provider storage options and how they can gain from transporting block storage flows over a 10GbE network.

by Arista Networks

Arista EOS offers multiple programmable interfaces for applications. These interfaces can be leveraged by applications running on the switch, or external to EOS. Arista’s newest interface, EOS API (eAPI), allows applications and scripts to have complete programmatic control over EOS, with a stable and easy to use syntax. Once the API is enabled, the switch accepts commands using Arista’s CLI syntax, and responds with machine-readable output and errors serialized in JSON, served over HTTP. DevOps teams will be very impressed.

by Arista Networks

Arista Networks’ award-winning Arista 7500 Series was introduced in April 2010 as a revolutionary switching platform, which maximized data center performance, efficiency and overall network reliability. It raised the bar for switching performance being five times faster, one-tenth the power draw and one-half the footprint compared to other modular data center switches. Just three years later, the introduction of the Arista 7500E Series modules and fabric delivers a three-fold increase in density and performance with no sacrifices on functionality, table sizes or buffering with industry-leading 1,152 x 10GbE, 288 x 40GbE or 96 x 100GbE in the same quarter-rack 11RU chassis. This whitepaper details scale-out cloud network designs enabled with the new Arista 7500E second-generation linecard and fabric modules.
