我决定伸手与Arista网络的CEO杰肖里·尔，开始的几个老总。我明白，她花时间来回答我的问题。我希望它提供了市场，企业和CEO本人一些观点。
这是不寻常的思科如此针对性和竞争力。我认为这是Arista的同类最佳的产品和恭维我们的验证。思科是在反应非常好，在经典的企业交换强大的统治地位。然而，思科不得不应付在几个行业分化暂时落后。客户的购买行为是因为云计算的破坏，他们的业务和毛利率模型是破坏并且也因为现代的芯片和软件的技术破坏。
What is the state of networking OS evolution and software-defined networking and Arista's role in it?
Isn’t it strange that hardware changes every 1-2 years but the core network operating system has not seen major changes in decades? The majority of the Internet is still powered with Cisco IOS which is 20+ years old. While tweaks or improvements have been made on modularity with Juniper’s JunOS or the introduction of a Linux based OS with Cisco NXOS - there really has not been a modern resilient open networking OS purpose built for cloud and data center environments. This is where Arista's Extensible Operating System – EOS is so powerful.
Built from the ground up based on an open Linux kernel, the fundamental advantage of EOS is enforcing a state agnostic system database (SysDB) suitable for real time operations. In EOS, the switch recovers seamlessly (as opposed to a restart or replay) from any condition causing process restart.Arista EOSis also controller friendly and can easily adapt to evolving specifications such asOpenflow.Arista developed an advanced operating system that would take 5+ years and thousands of man hours to recreate. This is what drew me to the company and is the key foundation.
What are your thoughts on these independent tests? It is an "understanding" that if you pay for the test you will always win. Do you think that an independent testing center should be used by all vendors? Not paid for by vendors but by others like the customers?
基于标准的RFC测试不经常模拟真实世界的工作条件，但一个良好的基线。一些组织，特别是那些依赖于大学，如E-ANTC和UNH，有着悠久的历史和良好的声誉。同时，我们欢迎产业带动多厂商的独立测试，如those conducted by网络世界where no vendor has tried to skew or pay for the tests. Pay-for-play tests are often contrived by a single vendor, do not represent real world and are ultimately discredited by any savvy customer, who will look to do their own independent analysis. Clearly I am not a big fan or advocate of pay-for-play tests.
There's been a lot written by other bloggers that your product saves money over Cisco.Can you tell us in detail how your product saves customers money over other products?
The问题比较was between Cisco's recommended 'best practice' design of using the Nexus 7000 in the aggregation, the Nexus 5000 in the access, and the Nexus 1000v for the vSwitch. This was contrasted with the Arista 7500 in the aggregation and 7100 Series in the access and used Arista's VM Tracer to achieve physical-to-virtual integration. The cost savings came from several sources
1) Network hardware pricing
2）网络接口卡
3）避免了对主机互连供应商特定的SFP电缆
4) Avoiding the required Enterprise Plus version of ESX needed for the Cisco 1000v
5）电力成本基于美国能源部平均定价
Since this was published over a year ago pricing has changed on some components, but the overall cost savings that can still be realized by using Arista 7000 family is still significant and marked.
Let’s talk about EOS Central, what is it and how do you think it will change the way customers look at your products and the cloud?
I am personally excited about EOS Central, as this was inspired by application networking vendors such as F5 who have taken a more application and vertical solution focus to networking than plain connectivity or models where all features must come from the vendor. It is also very appealing to our technical and engineering community of customers who want to harness the power of Arista EOS more. EOS Central, launched in May 2011, offers development tools to bridge the gap that exists today, actively sharing EOS extensions, code samples, collaborative forums and early examples of use-cases in key markets like Big Data, Virtualization, and latency analysis.
In what ways does your products compete with other vendors? So if you could, by product, tell us which vendor/product they compete against and why you think yours are a better value.
一方面我可以说我们没有竞争对手，因为我们已经采取了这样一个独特的垂直方式向现代云网络和在另一方面，你可以说大家谁建立了一个10GbE交换机是我们的竞争对手！这两个陈述是真实的。很清楚的是，我们没有建立传统超额配置的网络，并真正关注的密集云计算，存储和网络的交叉点。这个问题一直没有得到来自经典网络公司妥善解决。InfiniBand作为一种技术，它试图这样做，但仍然是小众高端集群。高性能以太网是主流价值数十亿美元的市场机会，并支持下一代数据中心。雷竞技电脑网站
Many have wondered if you will make a push into telco carrier sales to compete against Juniper, Cisco, Alcatel and others?
我们不使用TDM /光纤与IP作为一个覆盖传统的电信应用的健康，而且是新的视频/媒体和高性能的托管应用程序和云服务供应商很自然的应用。一些高调的公司，包括全球最大的SaaS供应商，云服务提供商，托管和服务提供商正在使用阿里斯塔对于这样的应用。他们已经进行了好几个月的试验，并看到显著功率，占用空间，规模和运营优势。
What new verticals, segments do you see Arista moving into within the next few years?
Arista's strongest vertical to date has been financial services [particularly High Frequency Trading firms] and we continue the value the strong partnership we have here with 150+ customers in this space. We have been pleasantly surprised with the rapid acceptance of our solution in just two years. We are now making inroads in several other verticals with that same application focus including cloud providers, Web 2.0 companies, media and health/education research institutions. These are natural expansions for us.
If you had to pick one vendor who is your biggest competition and why?
I have a healthy respect for Cisco, both as my former long-time employer and their dominance in the enterprise switching market. Despite their current product deficiencies and challenges, they are a formidable competitor with long-term relationships, an army of CCIEs in their installed base, and solid customer loyalty.
Recently I wrote on my blog from Interop Las Vegas aboutHP Labs and an optical backplanefor switching equipment. Do you think this will be the next big thing as I do, or do you see something different coming? Something that will be a game changer?
越来越生产价值和未来的研究阶段的出这是伟大的看到像HP创新和肯定光学背板的大公司。话虽如此，我认为我们仍然可以把串行铜背板技术更大的限制，实现背板容量兆兆位为好。我不认为这是一个改变游戏规则，但在超过100Gb的超高速应用的理想选择。
Let’s talk green, many companies talk about it but they really don’t do it. Can you tell us Arista is going in the green space and how customer can save money with your products?
While the power savings make an impact on the operating costs of the equipment, the main benefit most customers realize is on getting more computational capacity out of a given facility with a fixed power envelope. For instance, in a 3MW data center there is a maximum amount of compute capacity that can be deployed before you run out of power, and the costs for the facility at max power are relatively fixed.
Everything you can do to reduce the power draw of the network and optimize airflow efficiencies increases the number of servers that can be deployed. As an example: A 3MW Data Center can support 5000 600w servers in a perfect world, this would take 125 cabinets and we can assume that in a legacy enterprise data center design this would require 250 ToR switches and then an aggregation tier. Sticking with current design practices we will use 3:1 oversubscription from the host ports to the uplink ports on the ToR switch (48 host ports, 16 uplink ports) and deploy a wirespeed routed backbone.
Connecting 5000 10GbE dual homed servers with Arista will take 250 7050s and 12 Arista 7500s. The power draw of the network will be 75.6kw which will cause a reduction of 126 servers, or about 3 racks and is 2.5% of the total power available.
Max compute density with Arista is 4874 servers.
连接5000的10GbE双归属服务器与思科（使用他们的最佳实践设计指南，其中建议在Cisco 5500的FCoE和Nexus 7000）将采取278个的Nexus 5548s（每个提供每柜36名的主机与上行链路的12个端口）和26个的Nexus 7018s（各输送线速128个10GbE端口，尽管由于该用途侧到另一侧的气流需要2个柜每个开关）。这个网络已经超负荷，并在骨干层不线速和实际需要的13个的Nexus 7018s的第二阶段，以使第一阶段。
Nexus 5548 = 390W
278 Nexus 5548 = 108kW
Nexus 7018 with 16x32 port 10GbE M1 Modules (needed for L3 routing) = 11kW
39 Nexus 7018s = 435kW
思科力量吸引了5000端口- 525 kw,或about 17% of the overall power available and causes a reduction in server capacity of 875 servers.
与思科最大的计算密度是4125台服务器。
把一个理性的美元在这如果我们assu图med this was a public cloud deployment where every IT asset is monetized and assumed $50/VM at 20VMs per server, the monthly revenue on the two data centers is as follows:
Arista Data Center: $4.874M/Month
Cisco Data Center: $4.125M/Month
在阿里斯塔设计节省了足够的力量，每年加$ 8.98万美元的云计算网站的底线。
Right now we are at 10gbps, moving to 40gbps and beyond. Where do you see Arista moving to and how fast? Could we see 100gbps at the switch level by 2012?
I am very bullish about 10Gbe as a mainstream transition in the data center in 2012-2014. The 1GbE transition took 5 years and happened from 2000-2005. 10GbE has primarily been an uplink and core technology but has been moving to key horizontals such as dense storage, high end computing and virtualization. These high performance transactions demand high performance and low latency. With the advent if new multicore CPUs from Intel and AMD, I expect the integration of 10GbE and 10GBASE-T into the server mainboard to realistically happen in 2012 onwards. This will create a natural pull to "spine" aggregation switching of 40Gbe and 100Gbe thereafter.
Do you see Arista adding a NAC to its product line to help with security?
NAC has had mixed reception and deployment in the wiring closet and almost a non-starter in data centers, where the concept of security is less tied to identity and more to the application. So we try to work with industry-leading security vendors to build EOS extensions and innovative firewall options with them.
Additionally, given the push towards virtualization by natively integrating with the virtual machine platform we are able to understand what is actually connected and apply appropriate policy and segmentation/forwarding characteristics by authoritatively interconnecting with the virtualization platform.
What is the one question when meeting with potential customer that you get the most and why?
Ah, good question! The most common question since we are a young and fast growth company, I get asked is "What is your exit strategy? Are you going to be bought?" They fear that we will be purchased by an unfriendly company. Our customers and well-wishers want us and view us as a credible viable alternative solution and want us to be independent. This is our goal as well.
许多厂商我跟弹出客户的采购方面，许多已经从15-30天移动到60-90天。你认为这是在客户手中失控或者是电源？
我还没有看到大的变化在这里坦白地说。也许阿里斯塔购买需要得到更大的去看看！
iPad，iPhone或Android的？
I am a slow adopter of consumer technology ...iPhone and contemplating iPad sometime in the future.
对你的MP3播放器是什么类型的歌曲？
