Traffic volumes are exploding in the data center due to the increasing efficiency and density of highly virtualized cloud computing infrastructures and larger, more complex data sets. A single application or storage server connected at 10Gbps can now generate bi-directional flow rates in excess of two billion packets per day with aggregate daily traffic in many cloud data centers measurable in petabytes. To handle these loads, deployments of multi-path 40Gbps Ethernet spine and leaf interconnects are becoming the norm, with price-competitive 100Gbps Ethernet connectivity on the very near horizon. Arista Data ANalyZer (DANZ) is an integrated feature set in Arista’s Extensible Operating System and is currently available on Arista Networks 7150-series switches. DANZ provides a solution to monitoring and visibility challenges at 10/40Gbps and higher with unmatched price-performance and precision. DANZ functionality will be available across the majority of the Arista product line in the summer of 2013. This white paper describes DANZ.

At Ixia’s iSimCity I sat down with Michael Francini, System Engineer/Technical Marketing Engineer at Arista Networks to discuss the problem of VMs joining, moving and being deleted from an Ethernet fabric. Michael demonstrates how Arista’s VM Tracer interacts with VMware’s Vcenter to provide administrative views to both network and virtualization operations groups and most importantly auto provision Arista’s Software-Defined Cloud Network to support VM joins, moves and deletes.

The networking industry at an inflection point driven by IT business leaders taking greater control of their network infrastructure to lower operational cost and increase IT delivery flexibility. Open networking promises to deliver greater control, lower cost and an injection of innovation not seem before in the networking industry. To understand these dynamics, we are conducting a CEO podcast series with industry thought leaders and visionaries all of which are meeting with IT leaders at the Open Networking User Group or ONUG in Boston on Feb 13th. Jayshree Ullal , President & CEO, Arista Networks joins Nick Lippis for discussion on the state of open networking.

Ethernet networks have evolved significantly since their inception back in the 1980s, with many generational changes to where we are today. Networks are orders of magnitude faster with 10Gbps line rate switching as the norm. Moreover, today’s Ethernet networks offer sub-microsecond switch latency, traffic scaling and load balancing across redundant interfaces, and are reducing the management complexities with state-driven architecture and open interfaces for managing hundreds of switches through global, yet highly secured interfaces. Thousands of man-years of engineering effort have gone into developing features for enterprise switching and routing with each vendor developing their own software stack, thus creating a system where the forwarding logic and the hardware to switch millions of packets per second remains closed. Software Defined Cloud Networking (SDCN) is a term often used when a controller external to the forwarding logic and the actual switch itself programs the network devices to alter or enhance the flow of traffic.

If you are a virtualization and/or network administrator who wants to eliminate cloud boundaries and implement elastic computing, then download this paper. By overcoming the need for flat, Layer 2 networks, enterprises and service providers are able to take advantage of more scalable, proven Layer 3 technologies within their data center without sacrificing crucial application mobility.

This document provides an overview of how VXLAN works. It also provides criteria to help determine when and where VXLAN can be used to implement a virtualized Infrastructure. Arista, Broadcom, Intel, VMware and others developed the VXLAN specification to improve scaling in the virtualized Data Center.

In one of the most candid discussions with Jayshree Ullal, Arista Network’s CEO, she voices her view of Software-Defined Networking as not a market but a set of features. Jayshree views OpenFlow as but one in many APIs becoming available to program layer 2/3 networks. If you’re looking for SDN hype, then no need to listen to this podcast. But if you want a realistic view of this important industry trend, then listen up.

Data center operators are expanding data centers to deliver virtualized and cloud-based services including business continuity and disaster recovery solutions. These additional service and availability requirements lead to increased bandwidth and greater distances between geographically dispersed data center sites. As new services are added, data center environments that were once fiber-rich can quickly run out of fiber and find the associated cost for adding more fiber to be prohibitively expensive. Cost-effective embedded DWDM and distance extension solutions can reduce complexity, operating costs and enable a rapid delivery of new services. Find out how by downloading this whitepaper.

Advanced Event Management (AEM) is a powerful and flexible set of tools to automate tasks, customize the behavior of the system and associated operation of the switching infrastructure. Leveraging an open operating system, AEM allows operators to fully utilize the intelligence within EOS to respond to real-time events, automate routine tasks, and take local automated action based on changing network conditions. Simplifying the overall operations, AEM provides the tools to customize alerts and actions. This white paper describes Arista’s approach to Advanced Event Management.

Software Defined Cloud Networking (SDCN) is a term often used when a controller external to the forwarding logic and the actual switch itself programs the network devices to alter or enhance the flow of traffic. SDCN can be achieved via standard APIs that several hardware and software architectures intend to support. This white paper describes Arista’s approach to Software Defined Cloud Networking

The problems of network configuration changes required when virtualization operations managers need to move a VM between subnets are well documented. There are virtual networking options to solve this problem such as building very large flat networks, tunneling between subnets, and now a standard approach called VXLAN. VXLAN is a special encapsulation mechanism that runs between virtual switches and enables VMs to be deployed and moved on or between any server within the network. VXLAN requires no changes to the underlying IP addressing architecture and should require no major changes to installed infrastructure in the data center. Ken Duda Founder and Vice President, Software Engineering at Arista Networks joins me to discuss VXLAN, the first major protocol of virtual networking.

VMWARE VXLAN is a new network technology developed by VMware that enables stateful VM mobility across traditional L3 routed boundaries. This enables more freedom and flexibility in matching workloads to computing power. By enabling a larger, and essentially flatter network while building on top of proven models for stable scaling of networks such as routing and equal-cost multipath forwarding, VXLAN enables any workload to be provisioned on any virtualized host, anywhere in the network that is IP reachable. No longer do routed topology decisions restrict workload mobility.

If you are a VMware and network administrator who is building virtualized networks with more than 250 VMs or want to stretch a virtual machine farm across two data centers or two or more routed domains with full workload portability, then you need to read this white paper.
