==公司历史==
[[安迪·贝托尔斯海姆]]（Andy Bechtolsheim）1982年合作创立了[[Sun Microsystems]]软件系统有限公司并担任其首席硬件设计师。

1995年：大卫·切利顿（[[David Cheriton]])与贝托尔斯海姆合作创立了Granite System，一个在1996被思科系统（[[Cisco Systems]]）收购的千兆以太网产品公司<ref>{{cite news|url=http://news.cnet.com/Cisco-buys-Granite-Systems/2100-1001_3-223847.html|title=Cisco buys Granite Systems|publisher=CNET News|date=3 September 1996|accessdate=16 October 2011|archive-date=2014-07-14|archive-url=https://web.archive.org/web/20140714130802/http://news.cnet.com/Cisco-buys-Granite-Systems/2100-1001_3-223847.html|dead-url=no}}</ref>。

1998年：斯坦福([[Stanford University|Stanford]])学生谢尔盖·布林([[Sergey Brin]])和拉里·佩奇([[Larry Page]])与贝托尔斯海姆在切利顿家的前廊会面, 贝托尔斯海姆在这次会面中给了两位学生创立谷歌([[Google]])的第一张支票，切利顿也投资了相同数额<ref>{{cite news|title=Frugal after Google|author=Jacob Jolis|date=16 April 2010|work=Stanford Daily|url=http://www.stanforddaily.com/2010/04/16/frugal-after-google/|accessdate=25 June 2011|archive-date=2014-07-14|archive-url=https://web.archive.org/web/20140714145538/http://www.stanforddaily.com/2010/04/16/frugal-after-google/|dead-url=no}}</ref>。

2001年：切利顿和贝托尔斯海姆创立了另一家创业公司Kealia（于2004年被甲骨文系统有限公司收购）<ref>{{cite news|url=http://news.cnet.com/Ciscos+brain+drain+continues/2100-1036_3-5126160.html|title=Cisco's Brain Drain Continues|publisher=CNET News|date=16 December 2003|accessdate=16 October 2011|archive-date=2014-07-14|archive-url=https://web.archive.org/web/20140714140113/http://news.cnet.com/Ciscos+brain+drain+continues/2100-1036_3-5126160.html|dead-url=no}}</ref>。

1996年到2003年之间：切利顿和贝托尔斯海姆在思科系统担任行政职位，与Granite System的首位僱员肯尼思·杜达(Kenneth Duda)共同领导Catalyst生产线<ref>{{cite web|url=http://www.arista.com/en/company/management-team|title=Management Team|accessdate=12 June 2014|archive-date=2014-08-07|archive-url=https://web.archive.org/web/20140807163517/http://www.arista.com/en/company/management-team|dead-url=no}}</ref>。

2004年：他们三人一起创立了Arastra(后更名Arista<ref name="name-change" />). 切利顿和贝托尔斯海姆之前对谷歌的成功投资使他们得以完全独立投资成立了Arista Networks<ref>{{cite news|url=http://www.networkworld.com/supp/2009/outlook/010509-startups-to-watch.html|title=10 start-ups to watch in '09|publisher=Network World, Inc|date=5 January 2009|accessdate=16 October 2011|quote=Funding: Undisclosed amount from Bechtolsheim and David Cheriton|archive-date=2012-03-07|archive-url=https://web.archive.org/web/20120307115132/http://www.networkworld.com/supp/2009/outlook/010509-startups-to-watch.html|dead-url=no}}</ref>。

===可扩展操作系统===
EOS是Arista的网络操作系统,是一个可以在所有Arista设备<ref>{{cite web|url=http://www.arista.com/en/products/eos/features|title=Arista EOS : Key Features|quote=EOS provides a single binary image across all Arista networking platforms|accessdate=12 June 2014|archive-date=2014-08-11|archive-url=https://web.archive.org/web/20140811005502/http://www.arista.com/en/products/eos/features|dead-url=no}}</ref>和虚拟机上运行的独立镜像<ref>{{cite web|url=https://eos.arista.com/veos-running-eos-in-a-vm/|title=vEOS – Running EOS in a VM|publisher=Arista Networks|accessdate=12 June 2014|archive-date=2014-08-11|archive-url=https://web.archive.org/web/20140811005140/https://eos.arista.com/veos-running-eos-in-a-vm/|dead-url=no}}</ref>。

EOS通过一个基于Fedora的用户空间在未经修改的Linux 核心上运行<ref>{{cite web|url=https://eos.arista.com/using-tcpdump-for-troubleshooting/|title=Using tcpdump for troubleshooting|quote=Linux Fedora 12 as the foundation upon which the Arista EOS is built|date=16 June 2011|accessdate=12 June 2014|archive-date=2014-08-11|archive-url=https://web.archive.org/web/20140811004116/https://eos.arista.com/using-tcpdump-for-troubleshooting/|dead-url=no}}</ref>,并通常拥有超过100个的独立进程，称为代理程序。这些代理程序负责控制交换器的各种特性和功能，包括管理集成电路(ASIC)的转换,命令行界面(CLI),网络管理标淮(SNMP),生成树算法的网桥协议(STP),以及各种路由协议的驱动程序。

交换器的不同状态以及它的各种协议都记录在另一个名为Sysdb的进程中。把交换器的状态（存储于Sysdb中）和相应的处理进程（由代理程序负责）分隔开来使得EOS拥有了两个重要的特性：第一是软件的故障隔离，如果出现错误,相应的损坏会被限制在某一个独立的代理程序<ref>{{cite web|url=http://eos.aristanetworks.com/2011/05/the-joy-of-an-open-switch-operating-system/|title=The Joy of an Open Switch Operating System|date=1 May 2011|quote=Kill agents and watch them restart to see if EOS is as resilient as we say it is.|accessdate=8 November 2011|deadurl=yes|archiveurl=https://web.archive.org/web/20111112110518/http://eos.aristanetworks.com/2011/05/the-joy-of-an-open-switch-operating-system/|archivedate=2011年11月12日}}</ref><ref name="eos" />；第二是保持交换器的延续性，由于代理程序的状态被存储在Sysdb中,当一个代理重新启动时, 它可以读取之前的状态<ref name="eos">{{cite web|url=http://www.arista.com/en/products/eos|title=Extensible Modular Operating System|accessdate=12 June 2014|archive-date=2014-07-31|archive-url=https://web.archive.org/web/20140731022859/http://www.arista.com/en/products/eos|dead-url=no}}</ref>。

由于代理程序是独立的进程,他们可以在交换机运行时进行升级。这个特点叫做ISSU，全称为In-Service Software Upgrade。
EOS在Linux上运行使得交换器可以利用常见的Linux工具,比如tcpdump和通常的配置管理系统。 EOS提供了大量的应用程序编程接口(API)来实现与交换器的通讯和全方位掌控。

因此,它的命令行界面是通过Python脚本去调用这些API的命令集合, 提供类似于IOS的一个达到行业标淮的CLI服务。为了展示EOS的可扩展性, Arista创造了云视界(CloudVision)模块<ref>{{cite web|url=http://www.arista.com/en/products/eos/cloud-vision|title=CloudVision™ – Topology Agnostic Management for Cloud Data Centers|accessdate=12 June 2014|archive-date=2014-05-16|archive-url=https://web.archive.org/web/20140516081908/http://www.arista.com/en/products/eos/cloud-vision|dead-url=no}}</ref>,它扩展了交换器的命令行界面使得其能够使用一种以XML为基础的开放式实时通讯协议(XMPP)作为管理和配置的消息共享线路<ref>{{cite web|url=http://eos.aristanetworks.com/2011/08/management-over-xmpp/|title=CloudVision Multi-Switch CLI – Network Management over XMPP|date=23 August 2011|accessdate=16 October 2011|deadurl=yes|archiveurl=https://web.archive.org/web/20111017000830/http://eos.aristanetworks.com/2011/08/management-over-xmpp/|archivedate=2011年10月17日}}</ref>。这个特点是通过在命令行界面中利用开源的XMPP Python库实现的。

===可编程性===
除了所有在Linux环境中原来就支持的标淮编程和添加脚本的能力以外,EOS还可以使用不同的方法进行编程。高级事件管理<ref>{{cite web|url=http://www.arista.com/en/products/eos/aem|title=Advanced Event Management (AEM)|accessdate=12 June 2014|archive-date=2014-05-16|archive-url=https://web.archive.org/web/20140516081523/http://www.arista.com/en/products/eos/aem|dead-url=no}}</ref>可以用来应对各种事件,并自动触发CLI命令。当转换器改变状态时,执行任意脚本或发送警报，例如一个接口断开或虚拟机迁移到另一台主机。事件监视器跟踪对硬件位址(MAC),地址解析协议(ARP)以及路由表在本地SQLite数据库作出的变化，以应对之后的基础Sql数据查询<ref>{{cite book|last=Donahue|first=Gary|date=24 October 2012|title=Arista Warrior|url=http://shop.oreilly.com/product/0636920022435.do|publisher=O'Reilly Media|isbn=978-1-4493-1453-8|chapter=Chapter 27: Event Monitor|accessdate=2 February 2014|archive-date=2014-03-31|archive-url=https://web.archive.org/web/20140331173936/http://shop.oreilly.com/product/0636920022435.do|dead-url=no}}</ref>。
EAPI(外部API)<ref>{{cite web|url=https://eos.aristanetworks.com/2013/03/eapi-learning-the-basics/|title=eAPI: Learning the basics|accessdate=2 February 2014|deadurl=yes|archiveurl=https://web.archive.org/web/20140410110609/https://eos.aristanetworks.com/2013/03/eapi-learning-the-basics/|archivedate=2014年4月10日}}</ref>提供了特殊版本的JSON-RPC接口来执行CLI命令以及获得相应生成的JSON对象输出。

所有Arista的交换器均採用商业用硅，而非定製的专门交换用集成电路([[Application-specific integrated circuit|ASICs]])。这样可使Arista在压低价格的同时可及时置换最新纳米工艺的处理器，如果採用定製的芯片则无法达到这一效果。主要的竞争对手思科（ [[Cisco Systems|Cisco]]）和瞻博网络（[[Juniper Networks|Juniper]]）现在也开始一一效仿这一设计<ref>{{cite news|url=http://www.networkworld.com/news/2011/031011-cisco-jawbreaker.html|title=Cisco's 'Jawbreaker' seen as response to competitive pressure|publisher=Network World, Inc|date=10 March 2011|accessdate=29 September 2012|quote=But basing any product on merchant silicon is a "huge departure" for Cisco|archive-date=2012-10-24|archive-url=https://web.archive.org/web/20121024035211/http://www.networkworld.com/news/2011/031011-cisco-jawbreaker.html|dead-url=no}}</ref>，导致很多互相竞争的产品都建立在同一种芯片上。比如博通公司（[[Broadcom]]）的Trident芯片就同时用在了思科的Nexus交换器[[Cisco Nexus switches]]、瞻博的QFX交换器、Force10、[[IBM]]和惠普（hp）的交换器上<ref>{{cite news|url=http://etherealmind.com/merchant-silicon-vendor-software-rise-lost-opportunity/|title=Merchant Silicon and Vendor Software – The Hype in 2012|publisher=EtherealMind / Greg Ferro|date=6 January 2012|accessdate=29 September 2012|quote=Even Cisco [...] has a Broadcom Trident chipset in their Cisco Nexus 3000 product|archive-date=2014-07-28|archive-url=https://web.archive.org/web/20140728195356/http://etherealmind.com/merchant-silicon-vendor-software-rise-lost-opportunity/|dead-url=no}}</ref>。这种芯片与其余系统的整合设计（包括与[[Media access control|MAC]]、[[PHY (chip)|PHY]]和设备驱动在控制平台上的整合）与配套软件一并成为区分各个公司产品的主要因素。

2013年11月，Arista Networks开发了Spine网络，将主干加分支式结构与单层网络相结合，以达到缩减运营成本的目的<ref>{{cite news|url=http://www.networkcomputing.com/data-networking-management/arista-unveils-single-tier-ethernet-swit/240163491#|title=Arista Unveils Single-Tier Ethernet Switches|publisher=Network Computing|date=4 November 2013|accessdate=3 December 2013|quote=Arista calls the new devices "spline" switches, meaning they can be deployed in a single-tier network of up to 2,000 servers|archive-url=https://web.archive.org/web/20140410064011/http://www.networkcomputing.com/data-networking-management/arista-unveils-single-tier-ethernet-swit/240163491|archive-date=2014-04-10|dead-url=yes}}</ref>。
