Big Data

January 27th, 2014

By Arista Networks

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

January 27th, 2014

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 Launches Industry’s Broadest Networking Programming Environment with Its New Nexus® 9000 Product Line

November 6th, 2013

CiscoProgrammingEnvironmentNexus9000BradleyWongToday’s networks are restricted to configuration programming via CLI, but what if applications can call upon network resources automatically or if application developers are provided access to network state, topology, performance and other information? How might applications change and user experience improve? How may a networking programmable environment enable automated provisioning, orchestration and management? Could a programmable network enable a new era of IT and an industry of network aware applications just when the Internet of Things is starting to emerge? The Cisco Nexus® 9000 product line provides a wide range of programming options through an enhanced version of the Nexus Operating System (or NX-OS) that ranges from APIs to direct programming via its built-in Linux BASH environment, RPC, RESTful APIs, JSON, Python etc. I’m joined by Bradley Wong, Distinguished Engineer, Technical Marketing at Cisco, as we review the Cisco Nexus programming environment, its programming options provided to developers, use cases and potential industry impact.

The Era of Application Centric Networking

September 23rd, 2013

By Nick Lippis

IDC reports that in 2012, Android and iOS combined for 87.6% of the 722.4 million smartphones shipped worldwide, up from 68.1% from 2011. IDC also predicts the expected value of the cloud computing market will increase as much as 130% to $43 billion in 2016. It’s clear that not only are applications being accessed on smartphones and hosted in public and private clouds, but business units are demanding and receiving self-service IT delivery. At the Open Networking User Group (ONUG) in Boston hosted by the Lippis Report and Fidelity Investments large financial service firms showed that self-service Virtual Machine (VM) creation and deletion trend lines are growing exponentially. These trends are powerful, and they are only in the early stages. This poses a challenge to network designers and planners as the rulebook they have referenced for the better part of a decade has become antiquated and a new model to build branch office networks is desperately needed. Download this white paper to find out how to build modern branch office networks in the era of application centric networking.

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

August 11th, 2013

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.

by IBM

Into a world populated by position papers, statements of direction and technology roadmaps, IBM introduces its latest solution that supports the next major advance in enterprise communications, which is Software Defined Networking (SDN). SDN is a new network paradigm that separates network control logic from the underlying network hardware. IBM is putting it to work with IBM SDN for Virtual Environments (SDN VE), a network overlay solution that supplies a complete implementation framework for network virtualization. In short, SDN VE software supplies a core component of SDN architecture, which is fully deployable for data center expansion. The purpose of this white paper is to provide an overview of the functions and benefits of SDN VE, and outline the steps to implementation.

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

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.
