By Lippis Enterprises

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.

AgilePorts over DWDM for long distance 40GbE

Get the White Paper

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.

IP Ethernet Storage

Get the White Paper

By Arista Networks

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.

Cisco Nexus® 9508 Power Efficiency Test

Get the White Paper

By Nick Lippis

Cisco launched its Nexus® 9500 series of data center modular switches, which Cisco promises offers not only the highest port density of 10/40/100GbE, and the most programmable and fastest packet forwarding modular data center switch in the industry, but the most power efficient too. To verify and measure the power efficiency claim, Cisco engaged the Lippis/Ixia team to test the new Nexus® 9508 modular data center switch for power draw at scale. We found that the Nexus® 9508 sets a new record in data center modular switch power efficiency drawing some 3.85Watts per 10GbE port at a scale of 1,152-10GbE ports populated in a single chassis.

Nexus® 9000 Programmable Network Environment

Get the White Paper

By Nick Lippis

The definition of Software-Defined Networking being the separation of data and control plane offered little to DevOps professionals or network engineers seeking a programming environment to customize their network and automate opera¬tional tasks. With the introduction of the Nexus® 9000, Cisco is offering the most compre¬hensive set of network programming options that delivers programming tools through an enhanced version of the Nexus Operating System (or NX-OS), which ranges from direct switch programming via its built-in Linux BASH environment, open RESTful APIs with JSON and XML support, direct integration with Python, etc. Most network engineers will opt to enroll in a Linux programming course versus obtaining another CCIE certification after reading this Lippis Report Research Note. In this research note, we review Cisco’s new programming environment detailing its options, use cases and industry impact.

A Technical Review of Cisco’s Wi-Fi-Based Location Analytics

Get the White Paper

By Dr. James Little and Dr. Brendan O’Brien

The rapid increase of mobile devices is making Wi-Fi the preferred method of network access, predominantly within buildings, but also outside. This trend presents businesses with both tremendous potential and unique challenges. Location analytics, in conjunction with the Cisco® Mobility Services Engine (MSE), enables businesses to realize unprecedented benefits from location-based services:

● Location analytics: Estimates the number of visitors, the amount of time they spend, and the frequency of their visits within the site

● Advanced analytics: Provides knowledge of movement patterns by these visitors while they are in the building

Together, these analytics provide detailed insights into general behavior patterns of people moving and interacting within a venue or open space. Location analytics uses advanced data mining techniques tuned to the type of data Wi-Fi location provides. This data is based on potentially millions of position triangulations made per day by Cisco’s MSE. This white paper discusses the technology and capabilities behind Cisco’s location analytics.

By HP

Gregory Bell, Head of Technical Services, Ballarat Grammar said “The Sentinel SDN application takes away a lot of the manual labor that we used to do. We now know exactly where the infections are and how many there are—we can detect threats and respond in a proactive manner. That saves us hours of work every week.” Ballarat Grammar is a K-12 independent Anglican school located in Victoria, Australia. An extensive parkland campus hosts a flourishing community of 250 faculty and 1,400 students, with over 200 of the students living on campus in boarding houses. Ballart Grammar looked toward HP’s SDN portfolio to increase student and faculty productivity and educational opportunities by allowing users to bring their own devices and securely connect to the network.
