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 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.

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.

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.

Networks today require predictable performance and are much more aware of application flows than traditional networks with static addressing of devices. Enterprise networks in the past were designed for specific applications while new cloud designs in the data center can address a multitude of applications. This is clearly a radical departure from today’s oversubscribed networks in which delays and high transit latency are inherent.

The standard for 10 Gigabit Ethernet (IEEE802.3ae) was ratified in 2002. While 10GbE deployments have grown every year since then, the technology has primarily been used to interconnect switches and routers. Almost all of the server connections in data centers have remained at 1 Gbps, limiting the amount of network throughput available to each server. With recent enhancements in CPU performance, system I/O, and storage I/O the gigabit network has increasingly become the application and workload performance bottleneck.
The primary reason for staying with Gigabit Ethernet has been cost-performance. Until recently it has been more cost-effective to have multiple GbE connections rather than a single 10 GbE port. In addition, most installed servers typically cannot utilize the full bandwidth of a 10 GbE connection. However both of these factors are changing, which are leading to widespread adoption of 10 GbE for server connectivity over the next few years.

The adoption of virtualization in datacenters creates the need for a new class of networks designed to support elasticity of resource allocation, increasingly mobile workloads and the shift to production virtual workloads, requiring maximum availability. Building a network that spans both physical servers and virtual machines with consistent capabilities demands a new architectural approach to designing and building the IT infrastructure. Performance, elasticity, and logical addressing structures must be considered as well as the management of the physical and virtual networking infrastructure. Once deployed, a network that is virtualization ready can offer many revolutionary services over a common shared infrastructure.

Performance and stability of the network is a business requirement for datacenter networking, where a single scalable fabric carries both network and storage traffic. Management processes must be scalable for successful deployment and operation, requiring a high degree of automation and integration into the customer’s unique environment. The design and architecture of the network operating system provides the foundation for meeting these requirements. The monolithic software architecture that runs on almost all of today’s network switches presents a fundamental design limitation to high network reliability. The stark reality is that a single bug or defect anywhere in the OS exposes the entire system to disruption since there is no mechanism for software fault containment. At the same time, with no isolation between multiple tasks it is difficult to scale these systems from a performance perspective or to add new functionality. In fact, making any significant changes to a code base that is measured in millions of lines of code will reduce product stability and reliability. The fragile monolithic approach inherently prevents extending the network operating system to implement new features such as integration with customer specific management processes.
