January 27th, 2014

By Arista Networks

Existing 40GbE solutions are limited to 10km and require costly upgrades to DWDM systems to enable long haul extensions. The AgilePorts feature enables groups of adjacent SFP+ ports to be configured for 40Gb operation using 10Gb transceivers and cables providing maximum port flexibility and a seamless migration from 10Gb to 40Gb. This enables the use of inexpensive and simple 10Gb DWDM systems to extend a 40GbE service. Arista AgilePorts allows four 10GbE SFP+ to be combined into a single 40GbE interface for easy migration to 40GbE.

BIG DATA BECOMING A COMMON PROBLEM
IDC projects that the digital universe will reach 40 zetabytes (ZB) by 2020, an amount that exceeds previous forecasts by 5 ZBs, resulting in a 50-fold growth from the beginning of 2010. With an ever-increasing amount of this data being unstructured it is changing the fundamental ways in which we manage and extract value from data. The term unstructured data refers to information that either does not have a pre-defined data model and/or does not fit well into relational tables. Generally it is text-heavy, but may contain other data such as dates, numbers, etc. This data comprises what is more commonly known as big data. In the past the ability to process big data was proprietary and expensive, with few people who knew how to deal with it. Mobility, social networking and search data all comes in as unstructured and needs some form of big data analytics to help increase its value. For many this means using big data analytics on the front-end and putting the data once sorted and processed into traditional relational databases on the backend – but without some preprocessing this is not possible and large amounts of relevant information are lost.

Arista is committed to supporting big data clusters in the way they were designed to operate with a non-blocking, deep buffered, high-speed data center network. This coupled with Arista’s EOS, the world’s most advanced network operating system, allows best-in-class native integration with popular big data distributions such as Hadoop.

Traditional storage networks and costs are growing at an exponential rate. New requirements for compliance and new applications such as analytics mean that ever-increasing volumes of unstructured data are collected and archived. Legacy storage networks cannot meet the need to scale- out capacity and reduce capital and operational expenditures. In response to this challenge, new storage architectures based on Ethernet have evolved. How will this change the storage network? Most future IT asset deployments will leverage 10 10GbE and 40GbE for the underlying storage interconnect for newer applications. Arista Networks has responded to the need for a new
IP Ethernet storage fabric. Arista provides industry- leading products and solutions that deliver operational and infrastructure efficiencies that have been previously unavailable.

November 6th, 2013

By Nick Lippis

At the Open Networking User Group (ONUG) this past October 29th and 30th, hosted by JPMorgan Chase in New York City and attended by over 500 influential IT and industry business leaders, virtualized networking overlays and the need for high performance plus reliable underlays was top of mind. With 2014 and 2015 being the years of open networking pilots and deployments, respectively, much focus was on high-density 40GbE spine switches from Cisco’s Nexus® 9000 series, Arista’s 7500E and HP’s 11900/12900. At ONUG, IT leaders expressed multiple drivers for high-density 40GbE spine switches, including connecting thousands to hundreds of thousands of servers at 10GbE, support for IP storage and the high-growth of virtual connectivity via network overlays, all over a high-performance and highly reliable underlay. In this Lippis Report Research Note we explore the three reference designs for building 288-40GbE spine switches based upon Broadcom Dune, Broadcom Trident II and the new hybrid, custom plus merchant silicon, with an eye toward reliability and available based upon component count and measured in terms of Mean Time Between Failure.

Cisco Enhances VXLAN: Eliminates IP Multicast Requirement, integrates virtual services via vPath plus connects to legacy networks

Listen to the Podcast

May 27th, 2013

Han_Yang_Cisco_Enhances_VXLAN_Eliminates_IP_Multicast_Requirement_integrates_virtual_services_via_vPath_plus_connects_to_legacy_networksCisco introduced enhancements to its VXLAN implementation in the Nexus 1000V virtual switch that overcomes the requirement for IP Multicast. In addition Cisco is integrating vPath to VXLAN for service insertion that stitches virtual services into VXLAN overlay tunnels. Network services might include virtual firewalls, application delivery controllers, WAN optimization, network monitors, etc. A final VXLAN challenge that network teams are facing is how to integrate VXLAN into legacy networks and with existing physical networks, appliances and the enterprise WAN. We’ll hear if Cisco has any solutions to get around this issue as well. Han Yang of Cisco joins me to discuss VXLAN, without multicast and with vPath, and how it can be used to deploy virtual network overlays.

Today’s massive scale data centers offer high aggregate network bandwidth for large compute clusters. Fast, fat and flat networks are widely deployed with the more ubiquitous adoption of computer virtualization and the proliferation of clustered applications. Broadcom’s StrataXGS architecture-based Ethernet switches support the SmartSwitch series of technologies to ensure that such network infrastructure design requirements can be implemented comprehensively, cost-effectively and in volume scale. Broadcom’s Smart-Hash technology, part of SmartSwitch, implements several new hashing enhancements that improve network performance and overcome limitations imposed by traditional schemes. This white paper discusses current data center traffic trends, the implications of such and related enhancement featured in Smart-Hash technology.

Smart-Table Technology Enabling Very Large Server, Storage Nodes, and Virtual Machines to Scale Using Flexible Network Infrastructure Topologies

Get the White Paper

January 7th, 2013

By Broadcom

A critical element of cloud network scalability is forwarding table size of data center network switches. Forwarding table size impacts data center scalability, that is the number of servers and virtual machines (VM) per server, the ability to load-balance and provide full cross-sectional bandwidth across switch links. In turn, these scalability elements directly impact application performance and mobility. VMs and server sprawl, plus increased use of tunneling or overlay technologies, further exacerbate scaling challenges. This white paper explores forwarding table size requirements in private and public cloud data center networks, and considers how such requirements affect the design of data center network switches. It also describes features that are enabled by Broadcom’s Smart-Table technology, part of Broadcom’s SmartSwitch series of technologies, engineered specifically to meet feature and scale requirements of cloud networks.

Cisco’s Nexus 1000V-based Programmable Virtual Network Overlays

Listen to the Podcast

September 15th, 2012

This is the fourth and last podcast in a four part series on Cisco’s Open Network Environment or Cisco ONE. Cisco ONE utilizes the multi-hypervisor Nexus 1000V virtual switch to create virtual network overlays and will be enabling programmability through programmatic interfaces to its virtual supervisor module (VSM), enabling automation-centric provisioning. To make virtual overlays functionally equivalent to physical data center networks, virtual Layer 4-7 application network and virtual security services are added via its virtualization stack of related protocols and layered products. Gary Kinghorn, Senior Manager, Data Center and Cloud Solution Marketing at Cisco Systems joins me to discuss Cisco’s approach to virtual network overlays.

Duration: 22 minutes and 37 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:36 sec: Gary, would you like to add anything to my virtual network overlay discussion in the intro that’s unique to Cisco?

Question 2 @ 3:45 sec: What are some of the misperceptions that most need to be cleared up?

Question 3 @ 4:42 sec: Gary, you and I talked before about a network virtualization stack early this year, and now the conversation appears to have shifted to this virtual overlay concept. Are these really the same things that Cisco has been talking about for a while? Or what’s different and what’s behind the evolution?

Question 4 @ 7:11 sec: There’s a lot of discussion in the industry now about the virtual switch being a key strategic battleground going forward, and that presumably extends to virtual overlay infrastructures overall. We know that VMware acquiring Nicira gives them an overlay story as well that could lead to competition with Cisco specifically in this area. Is this a “battleground”, and if so, what makes Cisco’s approach different or unique?

Question 5 @ 16:23 sec : Lets talk use cases. When do you go from a physical network to a virtual one, when do you need overlays, and what are the applications that are going to be built on top of these new SDN API’s?

Question 6 @ 18:19 sec: Which use cases does Cisco see as virtual network overlays offering the most value today?

Question 7 @ 20:59 sec: The perception is that a lot of this SDN stuff is really out in the future? When and how do data center architects start to implement Cisco’s virtual network overlays?

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.

By Arista Networks

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

Lippis Report 185: Why Software-Defined Networking and Virtualized Networking Are Inexplicably Linked

January 29th, 2012

Computer networking vendors have been increasing the speed and port density of their Ethernet switches while reducing power draw and price per port. But while Ethernet switching hardware marches on linearly, thanks to 10, 40 and 100GbE, networking software is taking a different historical path as the pace of compute and network technology evolution has diverged, with networking lagging. Highly virtualized server deployment has broken traditional networking approaches on multiple levels, for example. In response, the industry is now developing a “virtualized infrastructure” or “stack” to add network flexibility. To close the technology gap, Software-Defined Networking (SDN) is promoted as the new “organizing principle” to deliver network software and service value. While it will be, likely, years before SDN’s organizing principles take hold, I propose that these two industry activities are inexplicably linked and phased; here’s why…
