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.
Arista 7124SX 10G SFP Data Center Switch,
Arista 7050S-64 10/40G Data Center Switch,
This report details test results of Arista Networks two ToR Data Center Switches; the 24 port 7124SX and 64 port 7050S-64. All 10GbE ports are populated and tested for performance, throughput, latency and power consumption. The Arista ToR switches test results are then compared against Brocade’s VDX 6720-24, IBM BNT G8124 and G8264, Force10 Networks S-Series S4810, Hitachi Cable Apresia 15000-64XL-PSR and Voltaire Vantage 6048. In addition to the Lippis Report suite of test, we evaluate the Arista products to measure their absolute lowest latency and performance variation. You have to download this report to see what we found. It’s impressive.
Arista Networks is at the forefront of public and private data center cloud networking, having most of its customers building extremely demanding infrastructure. As such it is working with early adopters and sees the problems that most other networking firms do not. This places Arista in a position to offer solutions first to market. In this Lippis Report video podcast, I talk with Jayshree Ullal, President and CEO of Arista Networks, as we discuss its virtualization strategy.
Arista Networks’ Latency Analyzer (LANZ) represents a revolution in
integrated network performance monitoring. For the first time, administrators
and applications gain near real-time visibility into congestion conditions as
experienced by the network itself. Rather than simply waiting for congestion to occur, LANZ provides granular
notification of impending congestion events detected at the network layer
directly to the application layer. This enables close integration with
applications and administrative workflows.
While servers and applications have fully embraced the concepts of automation, sadly the network infrastructure, on which they all rely, is still mired in legacy technologies. Current methodology, such as CLI, requires extensive hands-on provisioning and configuration by knowledgeable personnel. In modern cloud infrastructure, network managers must be able to centralize provisioning and configuration roles to improve reliability, minimize bring-up costs, and contain the expenses of creating a cloud data center service. Whether you are looking to maximize the efficiency and reliability of your existing operations, or you are looking to take advantage of a cloud-based infrastructure, fully automated provisioning is an essential capability, and Arista’s Zero Touch provisioning offers the first approach to automated network configuration.
Andy Bechtolsheim, Founder, Chief Development Officer and Chairman of Arista Networks, joins me to discuss how the public and private data center cloud network market is emerging and the new type of networking it’s requiring.
Arista Networks brings its first ever-public tested 7504 core switch to the Lippis/Ixia test at iSimCity were we test all 192 10GbE links for performance and power consumption. Nick Lippis interviews Sean Hafeez Network Consulting Engineer at Arista on cloud network design with Arista’s 7500 series of core switches.

VM Tracer offers the tightest integration between virtual machines and network infrastructure. Visibility in to virtualized infrastructure is key for management and operations of mobile and virtual environments.
The increase in utilization of virtual machines and increasingly virtualized resources in the data center has caused a reduction in network visibility into the virtual infrastructure. VM Tracer provides the visibility necessary for the network team to support virtual environments and the automation necessary for server administrators to be effective and efficient.
Servers, storage and networks form the anchors of today’s IT infrastructure. Companies around the world are constantly seeking to enhance this infrastructure. With 10GbE connectivity the new infrastructure requirements are distinctive and differ in many ways from the needs of traditional enterprise IT needs. The new environments often require unique compute density, power density and ultra low latency. Such hyper-scale computing environments – where deployments are measured by up to millions of servers, storage and networking equipment – are changing the way they approach IT to drive growth and decrease operational expenses.
Arista Networks views storage networking as a key horizontal technology in the data center and an important area of focus because of the architectural disruption that has started, but is far from finished. This white paper reviews all the major storage networking technologies and provides Arista’s view of a Unified Storage Strategy.

For many years, networks have been oversubscribed. Such oversubscription was tolerable in enterprise networks as the applications were not bandwidth intensive, but not anymore. In a datacenter, the primary reason for this oversubscription is insufficient uplink bandwidth from each rack. Each top-of-rack switch is typically connected to two aggregation switches for redundancy. However, half the uplinks are blocked by spanning tree to avoid loops in the network; this reduces the available bandwidth between the rack and aggregation layer of the network by 50%. Arista’s Multi-Chassis Link Aggregation (MLAG) feature removes this bottleneck and allows the utilization of all interconnects.

Extensibility is a system design principle where the implementation of the operating system takes into consideration future growth. It is a systemic measure of the ability to extend the operating system and the level of effort required to implement the extension. Extensions can involve the addition of new functionality or the modification of existing functionality.
