Cisco Nexus 3548 Top-of-Rack Switch Performance and Power Test

Get the White Paper

By Lippis/Ixia

The Cisco Systems Nexus® 3548 is the fastest ToR switch that we have tested at these Lippis/Ixia tests by a large amount. The Nexus® 3548 forwards packets in slightly more than half the time of the next fastest switch we have tested! That is, it’s nearly twice as fast as the fastest previous switch tested. The Nexus® 3548 is also the fastest IP multicast forwarding switch we have tested to date, being able to forward packets some 62.5% faster than the previously fastest ToR switch tested. The Nexus® 3548 is an engineering achievement for both its raw packet processing performance, congestion management and value added Algo Boost and Warp Mode technology.

Arista 7500 Scale-Out Cloud Network Designs

Get the White Paper

by Arista Networks

Arista Networks’ award-winning Arista 7500 Series was introduced in April 2010 as a revolutionary switching platform, which maximized data center performance, efficiency and overall network reliability. It raised the bar for switching performance being five times faster, one-tenth the power draw and one-half the footprint compared to other modular data center switches. Just three years later, the introduction of the Arista 7500E Series modules and fabric delivers a three-fold increase in density and performance with no sacrifices on functionality, table sizes or buffering with industry-leading 1,152 x 10GbE, 288 x 40GbE or 96 x 100GbE in the same quarter-rack 11RU chassis. This whitepaper details scale-out cloud network designs enabled with the new Arista 7500E second-generation linecard and fabric modules.

The Virtual Blind Spot Best Practices for Monitoring Virtual Environments

Get the White Paper

By Ixia/Anue

The “many in” notions that VMs are built upon become problematic when trying to trace a packet, or analyze packet flow. Even worse, in most organizations, the teams that handle the physical network are different than those that handle virtualization, ensuring finger pointing in the case of any issues. In this paper, we will consider the growth of virtualization, and the visibility issues arising from a traditional implementation. We will then overview Ixia’s Anue Net Tool Optimizer (NTO) solution and demonstrate how its product capabilities can help customers today, while using existing and familiar IT assets you have already deployed.

Intelligent Networking for the Optimized Agile Datacenter

Get the White Paper

by IDC Brad Casemore, sponsored by IBM System Networking

As the use of server virtualization has matured, IT organizations are realizing they cannot achieve an optimized and agile datacenter unless the network architecture is designed to support converged systems. Therefore, any approach to converged systems that leaves networking as a secondary consideration will be doomed to failure. Fortunately, the industry has responded with networking products that are integrated with converged systems architectures. These solutions deliver the high performance required for next-generation datacenters. This approach delivers benefits in several areas, including optimization of physical and virtual resources, reduction in ongoing management of virtual machines, increased security, and IT agility. This white paper describes the business and economic advantages of an intelligent datacenter network for converged system applications.

Arista EOS™ Precision Data Analysis with DANZ

Get the White Paper

By Arista Networks

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.

Best Practices in Big Data Monitoring

Get the White Paper

By Ixia/Anue

According to industry analysts Gartner, “Big Data are high-volume, high-velocity, and/or high-variety information assets that require new forms of processing to enable enhanced decision making, insight discovery and process optimization.” The world’s technological per-capita capacity to store information has roughly doubled every 40 months since the 1980s; as of 2012, every day 2.5 quintillion (2.5Å~1018) bytes of data were created. Big Data exceed the demands of a typical network because of the size and speed of the data traveling over the network. Almost everything about this new paradigm is different than what traditional networks were designed to handle. But there are some elements of networks running Big Data that are exactly like its more typical counterpart. You still need to monitor the performance of the network, make sure that the network is secure, and check the behavior of the applications that are running on it. And meeting these needs require a way to monitor Big Data; that is as revolutionary as it is – the network monitoring switch. In this paper, we will overview the issues posed by the surge of Big Data in industry, as well as the capabilities of a network monitoring switch to make the most of it.

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.

Is It Easy To Join, Move and Remove VMs in Avaya’s VENA?

Watch the Video

Elmer_Balino_Is_it_easy_to_join_move_remove_VMs_in_avayas_vena
To show how Avaya’s VENA supports VM dynamics we demonstrate Avaya’s Virtualization Provisioning Service management tool that integrates into VMware’s vCenter to provide an end-to-end view of the virtualized Data Center, including VMs, physical hosts, and network devices across both physical and virtual environments. We put this to the test at iSimCity and with the help of Jeff Cox Solutions Architect and Elmer Balino Product Verification Test Engineer at Avaya. The goal is measure the level of difficulty to join, move and remove VMs from the Avaya VENA fabric.
