For the Lippis/Ixia evaluation at iSimCity, Brocade submitted the VDX™ 6740, which is Brocade’s flagship Top-of-Rack (ToR) switch that’s built with Brocade’s Virtual Cluster Switching (VCS™) technology, an Ethernet fabric innovation that addresses the unique requirements of highly virtualized, cloud data center environments. The line-rate, low latency VDX™ 6740 fixed configuration switch is available in two models: the VDX™ 6740 with up to 64 1/10 GbE SFP+ ports, and the VDX™ 6740T with 48 1/10 GBASE-T ports and four 40 GbE SFP+ ports. We populated and tested the switch’s 10 and 40 GbE ports for performance and power consumption. In this podcast, Gautam Roy, Senior Product Marketing Manager at Brocade, joins me to review the VDX 6740’s test results.

Performance, resiliency and programmability across the entire network are now fundamental business requirements for next generation cloud and enterprise data center networks. Arista Networks has designed and delivered EOS (Extensible Operating System), a Linux-based network operating system, to address these requirements. EOS is a robust, programmable and innovative system, featuring a single software image that runs across the entire portfolio of Arista’s network switches. This guarantees consistent operations, workflow automation and high availability, while significantly reducing data center operational expenses. This whitepaper discusses current network operating systems and explains how Arista’s EOS architecture uniquely supports next generation data centers.
Deploying and taking advantage of new technology is top of mind for most organizations. Balancing the business benefits of adopting a rapid pace of innovation with the associated risks is a constant struggle; one most are losing. A major inhibitor to technology adoption is the ability to transparently insert new technologies into existing facilities without adversely impacting critical applications. The difficulty in doing this has had an almost paralytic effect on the adoption of beneficial new technologies. Unfortunately, operating with outmoded equipment can severely impact your bottom line causing further erosion in already shrinking budgets. Find out how Smart System Upgrade can help.

The VDX™ 6740 series switches are based on a single custom ASIC fabric switching technology and runs the feature-rich Brocade Network Operating System 4.1.0 (NOS) with VCS Fabric technology.
Arista 7500E is the most widely deployed spine switch of this new class of 288 40GbE modular switches. Over the past few months, the Lippis Report with Ixia tested the 7500E for layer 2 and 3 unicast plus multicast performance, congestion management, demanding cloud traffic performance, power consumption, the ability for its VOQ buffers to be adjustable, and if its 64-Way ECMP hash works as advertised as well as performance tested its 100GbE Line Card. If you’re building a cloud network, then you need to read this report first. In this report, we deliver the most comprehensive test and review of Arista’s 7500E modular data center spine switch.
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.
The Arista 7150S-24 SFP Data Center Switch is the fastest Top of Rack Switch we have ever tested in this series of public test. Find out just how fast the 7150S-24 can forward packets in your network by reviewing the latest public test information.
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.
During the Fall 2011 edition of the Open Industry Network Performance & Power Test for Cloud Networks Evaluating 10/40 GbE Switches, Extreme Networks submitted its X8 Data Center Switch. We tested this switch populated with 192-40GbE ports, the highest density in the industry. We found the lowest latency and power consumption to date in the industry.
Modern corporate networks are under increasing pressure to support a wider variety of applications thanks to mobile and cloud computing, desktop virtualization plus video traffic having skyrocketed. Not only are bandwidth rates increasing from 1 to 10 to 40 GbE, but most importantly network services are needed to manage and support a different application portfolio mix and network access methods. Network services such as firewalls, WLANs, network diagnostics and monitoring plus application performance acceleration are needed to deliver a consistently excellent user experience. Cisco recently announced an upgrade to its popular Catalyst 6k with the availability of the Supervisor 2T that included re-vamped high performance service modules to deliver these network services. Goyal, product line manager at Cisco Systems joins me to discuss which network services need to be available in modern networks.

While the Lippis Report test were being conducted of the Extreme Networks BlackDiamond® X8 Core and Summit® X670V ToR data center fabric switches at Ixia’s iSimCity, Darius Goodall, Product and Technical Marketing of Extreme joined me to discuss the firm’s latest product investment. We talk cloud network architecture and what’s unique about the new X8 and X670V.

Just as 10 Gigabit Ethernet (GbE) is going through widespread
deployment in the data center, the discussion has now shifted to even
higher speed interconnects—namely 40 GbE and 100 GbE By IBM
In July 2006, the Institute of Electrical and Electronics Engineers (IEEE) Higher Speed Study Group was formed to look into the next evolutionary step after 10 Gigabit Ethernet (GbE). In the past, Ethernet speeds would increase by a factor of 10. However, the next generation jump from 10 GbE to 100 GbE has proven to be a technological challenge. Some within the IEEE group felt that 100 GbE made sense for communication service providers and other backbone network providers, but not as a next step for servers—it was simply more speed and expense than would be needed for the near future. While the IEEE initially planned to standardize only on 100 GbE as the next step after 10 GbE, server vendors initiated a push in early 2007 to include 40 GbE in the standard, with the rationale that the effort used to develop 40 GbE would be used for the development of 100 GbE.
In July 2007, the IEEE 802.3ba study group was named, and it is the first standard to include two different Ethernet speeds—the 40 Gbps rate for local server applications, and the 100 Gbps rate for internet backbone—to serve both market needs. In June 2010, the official 802.3ba standard was ratified, opening the field to higher performance in server systems and components, data centers, network storage and systems, high-performance computing (HPC) clusters, data centers, carriers, and the like. This paper provides perspective on the placement and use of 40 and 100GbE.
