By Arista Networks

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.

The Role of 10 Gigabit Ethernet in Virtualized Environments

May 17th, 2010

Virtualization is rapidly becoming an essential tool for more fully harnessing and managing the power of today’s data center servers. In only a few years, standard x86 server technology has increased in performance and density so that today, multisocket, quad-core systems with 32 or more gigabytes of memory, are the norm. The combination of multicore computing and virtualization software such as VMware Virtual Infrastructure has enabled IT departments to bring server sprawl under control by running multiple independent workloads on a smaller number of servers. Today, fewer servers are required to do the same work, and their utilization levels have increased — both factors that contribute to greater energy efficiency and lower power and cooling costs.

As IT departments have discovered the benefits of server consolidation, they have also found that virtualization solves an even broader set of problems. Business continuity plans based on virtualization can make disaster-recovery solutions simple, reliable, and more cost effective. Virtual desktop environments can use centralized servers and thin clients to support large numbers of users with standard PC configurations that help to lower both capital and operating costs. Virtualization allows development, test, and production environments to coexist on the same servers, and it helps decouple application deployment from server purchasing decisions. New applications can be deployed in virtual environments and scaled on demand to accommodate the evolving needs of
the business.

This white paper addresses the RF interference challenges that result from high usage of a shared spectrum. It explores the limitations of standard Wi-Fi chip design and how this affects the ability of an IT organization to gather critical, actionable data about the wireless spectrum for effective troubleshooting. Finally, it introduces Cisco® CleanAir technology and explains how by integrating RF intelligence into the network, users gain tremendous insight into actual usage of the wireless spectrum. This insight is critical to proactively managing Wi-Fi networks to support mission-critical and latency-sensitive applications needed in today’s hospitals, distributed enterprises, manufacturing sites, retail stores, and offices.

Arista Networks Addresses A New Era In Cloud Networking

Listen to the Podcast

May 3rd, 2010

dougOur industry is in a compute innovation cycle thanks to virtualization and cloud computing and it’s changing fundamental networking requirements and design. These changes are beyond increased packet processing performance and ultra low latency. They extend to network design and product features that enable increased server virtualization scale, workload mobility and cloud computing. I discuss a new model for networking born out of data center virtualization and cloud computing with Doug Gourlay, Vice President Marketing at Arista Networks. This is Arista Networks’ first podcast; sure to be a classic.

April 19th, 2010

By Voltaire

This paper describes the challenges inherent in existing Ethernet solutions and how Voltaire’s new scale-out Ethernet architecture effectively addresses those challenges. Voltaire’s InfiniBand products and fabric management solutions have been addressing Data center architecture changes for years. Today, Voltaire delivers the fabric for the world’s largest supercomputers, the world’s fastest financial trading platforms, and the world’s most scalable database machines. Soon, Voltaire will extend its product offering to include Converged Enhanced Ethernet CEE switches and software, allowing end users with less demanding performance requirements to benefit from a far more scalable Ethernet fabric that also lowers overall fabric costs, lowers power consumption, has greater efficiencies, and simplifies management.

Switching Architectures for Cloud Network Designs

April 19th, 2010

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.

Moving to the Data Center over Ethernet (DCoE)

The industry is a buzz around Ethernet’s emergence as the unifying data center network fabric of choice.  Although 10GigE is very attractive as a unifying fabric — prices are dropping and adoption is rising — we’re still a long way from a unifying fabric in the data center. According to Nemertes, nearly 63% of organizations have no plans for network storage over 10GigE, while 71% have no plan yet to converge data center switching fabrics into one unified fabric. Standards organizations are still working to address the key challenges of latency, loss, and performance at scale, which are required to ensure that a converged infrastructure performs effectively for all data center applications.   For most organizations, the best approach may be evolutionary – one in which converging parts of the network such as access layer (in-the-rack) help address server/storage I/O complexity with higher performance 10GigE Converged Network Adaptors (CNAs) – makes good sense in the near term. As the enterprise needs for agility and lowered TCO converge with standards-based resilience and reliability, we will eventually arrive at the “data center over Ethernet” (DCoE).

I talk with Douglas Gourlay, Vice President Marketing and Anshul Sadana Vice President, Customer & Systems Engineering both from Arista Networks about a new age of network design in the cloud-computing era.

Enabling Collaboration with Cisco Catalyst 4500 PoE Plus

Listen to the Podcast

April 13th, 2010

saguptaPower over Ethernet (PoE) powers IT endpoints like IP phones and WLAN Access points. But newer devices like IP video phones, IP surveillance cameras, thin client display, next Generation IP phones, 802.11n WLAN access points and Pan Tilt Zoom (PTZ) Surveillance cameras require more than 15W of power so the IEEE recently standardized a new 30W PoE standard called PoE Plus. Soon most, if not all, corporations will have a mix of end points that require old PoE and new PoE plus power. IT leaders can meet these requirements by leveraging the enhanced PoE and PoE Plus features offered by Cisco’s Catalyst 4500 E-Series product line. Moreover Cisco has announced two new Catalyst 4500 Series Line Cards with readiness for PoE Plus and inline power up to 30W per port. I talk with Sachin Gupta, Director and Product Manager at Cisco Systems about these new PoE design features and what new options are available to IT architects as they build out corporate collaborative solutions.
