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.

Lippis Report 162: Why Network Performance of Data Center Ethernet Switching Products Matter More Now Than Ever

November 30th, 2010

nicklippis.jpgEthernet networking is now the single most important data center technology to assure the new IT economic model of centralized application delivery. Yes that’s right—Ethernet as the data center fabric is the stability point in data center design that will dictate if a data center or cloud facility can scale to support huge application and storage traffic loads. And if you think that Ethernet switch performance is not important then you would be as right as the engineers who designed the Tacoma Narrows Bridge. In this Lippis Report Research Note, we explain why network performance of data center Ethernet switching products matter more now than ever.

Lippis Report 161: The New Nimble and Innovative Avaya

November 15th, 2010

nicklippis.jpgFor as long as I have been following Avaya—and it’s been a decade since it was spun out of Lucent back in October of 2000—it has undergone three fundamental transitions. First, Don Peterson, Avaya’s first CEO, managed to fix Avaya’s balance sheet after Lucent saddled it with heavy debt. He also pointed the way toward IP telephony in his six years at the helm. Then came Louis D’Ambrosio, with high energy and confidence, to point Avaya in the direction of unified communications, and a software and services business model, while bringing the company private in 2007 through TPG Capital and Silver Lake Partners. In 2008, Charlie Giancarlo became chairman, while Kevin Kennedy took the helm, ushering in a new wave of innovation and nimbleness while re-engineering sales and channels plus absorbing the Nortel enterprise business. Yes, what a long, strange trip it’s been, but Avaya is now the most innovative in its history and well positioned for the post-recession business cycle. In this Lippis Report Research Note, we examine Avaya’s prospects and challenges.

BLADE’s CEO Vikram Mehta on Virtualization and Being Acquired by IBM

Listen to the Podcast

November 1st, 2010

Vikram MehtaMove a Virtual Machine (VM) from one physical server to another, and network port profiles, VLANs, security settings, etc., have to be manually reconfigured, adding cost, delay, security issues and rigidity to what should be an adaptive infrastructure. BLADE Network Technologies’ data center 1/10 and 40 Gigabit Ethernet blade and top-of-rack switches incorporate what its calls VMready with Virtual Vision that enables data centers to deploy VM-aware networks that automate network change management as VMs come online and move between physical servers within or across data centers. Vikram Mehta, CEO of BLADE Network Technologies (BLADE), joins me to talk about BLADE’s data center network virtualization strategy, plus the company’s pending acquisition by IBM. It’s a great talk, and we hit lots of industry nerves in this thought-provoking podcast.

Extreme’s Next Generation Gigabit Ethernet Switches Offer New Network Design Options

Listen to the Podcast

October 26th, 2010

Darius GoodallGigabit Ethernet networking has expanded to desktop connections in campus networking and to dense server connectivity in data centers. In short gigabit Ethernet has become mainstream with multiple use cases driving its growth. But a new generation of gigabit Ethernet switches is needed to satisfy market demands with attributes such as PoE-Plus, stacking, data center cooling, power efficiency and more. It’s these attributes and more that Extreme is delivering with its new Summit X460 Gigabit Ethernet switch. I talk with Darius Goodall, Senior Manager Product Marketing at Extreme Networks about the Summit X460 and the new network designs it enables.
