Ethernet 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.
In today’s economic environment, organizations are tightening budgets and streamlining wherever possible. Despite financial constraints, IT executives must continually seek out innovative, cost-effective technologies to improve business-critical communications, collaboration and productivity. One such solution is high definition multipoint video conferencing. As an alternative to expensive and time-consuming travel and audio conferencing, HD video conferencing has gained widespread usage. In delivering video technology to a broad user base, IT management takes the lead in strategically building infrastructure, capacity and access for an entire organization—a monumental task that requires a smart, creative approach.
Over the next few years Wi-Fi networks will transition to 802.11n technology. During this time, many networks will support a mix of 802.11a/g and 802.11n clients. Because they operate at lower data rates, the older clients can reduce the capacity of the entire network. ClientLink technology can help solve problems related to adoption of 802.11n in mixed-client networks by making sure that 802.11a/g clients operate at the best possible rates, especially when they are near cell boundaries.
For 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.
For those who have not reviewed or seen the Avaya Flare experience, this on-demand video provides you with a view of its easy to use video conferencing environment. It’s short so press start and get ready to be wowed.
Move a Virtual Machine (VM) from one physical server to another, and network port profile, VLANs, security settings, etc., have to be reconfigured. Many networking companies haven’t taken the critical step of giving complete visibility and control of the VM lifecycle from an infrastructure perspective. But with XNV, Extreme Networks is bringing this functionality and visibility to network administrators, tracking VMs and applying policy as they move throughout the network. Shehzad Merchant, Senior Director for Strategy at Extreme Networks, joins me for a discussion about Extreme’s approach to network automation and visibility of virtualized infrastructure through its XNV software module.
IT business leaders are faced with a great economic shift, while at the same time are afforded the opportunity of a shift in IT delivery models. Business leaders must balance maintaining their current infrastructure, while exploring these IT delivery innovations. Most importantly, IT business leaders need to use their IT budget, approximately 4% of corporate spend, to significantly enhance and reduce the other 96% of corporate spend. But it’s not just an economic calculus that is diving post great recession IT spending. IT leaders need to engineer their delivery to be flexible to support current business growth, ongoing change, and long-term business goals. Robert Taylor, VP of HP Enterprise Services joins me to discuss what he has learned from HP’s global 2000 customers as they emerge from the economic downturn and prepare for a new business cycle with IT.
Little-known Voltaire is a powerhouse in High Performance Computing (HPC) networking with a full line of InfiniBand switches and performance software. It has been in this market since 1997 and has amassed big system partnerships to distribute its products such as HP, IBM, Oracle, NEC, et al. But seeing the multibillion-dollar market for 10Gb and higher Ethernet switching as the new high performance data center fabric has motivated Voltaire to enter this mainstream market. Note the InfiniBand market is slightly north of $200m annually. Its motivation has materialized in the introduction of two top-of-rack switches and one core switch plus Unified Fabric Manager software for physical and virtual infrastructure management and Voltaire Messaging Accelerator (VMA) software which reduces application latency increases application performance. In this Lippis Report Research Note, we profile Voltaire and layout its strengths and challenges.
To exploit the benefits of server virtualization, data centers need to enable the dynamic and automatic movement of Virtual Machines while protecting their security and maintaining accessibility. Data center network plays a large role in delivering these and other important services for virtualized environments. Current networking switches are not aware of Virtual Machines, and this creates security and availability issues for both server and network administrators as they try to fully exploit the value of virtualization and manage this new environment.

One of the greatest obstacles of virtualization is the assignment and allocation of appropriate network resources as virtual machines (VMs) are provisioned amongst diverse network locations. Virtualizing a single data center introduces a number of challenges, not the least of which necessitates moves, adds and changes of virtual images, which adds network provisioning complexity and impacts IT administration workload. Virtualized data center networks need to provide automation, visibility and mobility to support multi-vendor storage, virtualization software and server environments.
Securing your LAN network infrastructure is challenging. Factors such as cost, network instability, risk of breach and ease of implementation all play an equal part in making the right decision to retrofit an insecure, albeit functional, LAN. This white paper outlines approaches to securing the network that we, at HP, know work, in addition to providing information about what we know does not work. Getting all of the correct pieces to fit together is not so easy, so we have also provided the necessary configuration specifics to help with securing some of those devices connected to your network that you may have forgotten about, such as network printers, VoIP phones and security cameras.
Multisite organizations are reducing the number of servers in their branch offices by moving applications to the data center. Yet, they continue to place a few essential applications locally because of performance, survivability or compliance requirements. By making use of x86 server blades, these lean branch offices can lower equipment and operating costs, right-size and simplify infrastructure, and improve hardware provisioning and remote management.
