The Lippis Report

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.

WAN bandwidth, or the lack thereof, is the single largest contributor to poor application performance in branch offices resulting in reduced productivity and the inability of IT to implement their entire strategy. This is especially acute as applications are increasingly centralized in data centers and video traffic starts to dominate flows all of which put more pressure on the WAN. A new approach to wide area networking takes advantage of virtualization concepts. WAN virtualization promises to reduce WAN cost and increase performance. If your WAN utilizes T1 MPLS links at $300/month or higher and ADSL between $10-$15/ month, then you can benefit significantly from WAN virtualization as it offers 3 to 4 times the bandwidth at lower cost and in the process eliminates WAN design constraints limiting IT business leaders. Keith Morris of Talari Networks joins me to discuss WAN Virtualization. I have first-hand knowledge of how good this solution works; if you fit the above profile, then listen up.

Having a plan to transition to IPv6 has moved way up in the priority list of IT projects for IT leaders as 2011 was officially the year we ran out of IPv4 unallocated addresses and not having IPv6 could cut-off corporations and applications from accessing the internet. In addition employees en masse are “BYOD” or bring your own device meaning smartphone and tables to work increasing the number of devices on the network significantly. These devices and their applications are driving support of both IPv4 and IPv6 as many mobile devices are now set for IPv6 as the default. As dual stack IP v4/v6 is the best practice, the real challenge lies within the domain name service or DNS. Infloblox has developed a range of solutions to automate the transition to IPv6 by supporting both addressing schemes. Tom Coffeen, Chief IPv6 Evangelist at Infoblox talks about solutions to automate the transition to IPv6. It’s one of our best IPv6 discussions.

The Inflobox plug-in module for VMware’s vCenter Orchestrator promises to bridge network and virtual IT team silos by enabling automated assignment of IP addresses to VMs. The Infloblox plug-in enables IP addresses to be automatically assigned to virtual machines in less than a minute and then constantly monitored and managed, which simplifies troubleshooting, accelerates time to value and offers greater flexibility for the virtual team. Steve Garrison, VP Marketing for Infoblox and I discuss the problems of networking in virtualized environments and how Infoblox’s vCenter plug-in solves them.

While the Lippis Report test were being conducted of the Brocade VDX™ 6730-32, Gautam Roy, Product Marketing Manager at Brocade joined me to discuss the firm’s latest product investment. We talk cloud network architecture, data center fabric and convergence with a focus on how the VDX™ 6730-32 Data Center Switch contributes and delivers on Brocade’s Ethernet fabric strategy.

You can’t manage what you can’t measure. Cisco’s next generation NetFlow provides deep application visibility, detailed measurement plus increased control and security for IT departments that are struggling to get ahead of an Enterprise application portfolio that is undergoing a massive transition thanks to mobile and cloud computing. Samuel Pasquier, product manager for Cisco Systems, and Adam Powers, chief technology officer for Lancope discuss best practices for securing and gaining visibility to applications that are flowing over enterprise networks with the next generation of NetFlow.

Andre Kindness, Senior Analyst at Forrester Research and Zeus Kerravala, principal at ZK Research join me to discuss the shift-taking place in data center networking. Data Center networking is at an inflection point thanks to industry transitions driving new economics, technologies and IT delivery via mobile and cloud computing. These market transitions happen only once every decade or so and we detail its dynamics in this industry analyst round table. We discuss virtualization, merchant silicon, software defined networking, the rise of best of breed products, what network designs are working and which aren’t. We end with how IT business leaders can navigate an industry is transition.

Power over Ethernet or PoE has evolved from delivering 7 Watts/port to support IP phones to now 60 Watts/port to power a wide range of devices that span WLAN access points, surveillance video cameras, video conferencing end points, IP turrets for financial trading, and now, thin client desktop devices to support virtualized desktops. The current high PoE standard is IEEE 802.3at that details 30 Watts/port, so Cisco’s Universal PoE or UPOE solution at 60W is a pre-standard offering. The key point about UPOE is that it provides a new range of design options in both power distribution, but more importantly, how virtualized desktops and other electronics are powered. Pradeep Parmar, Senior Marketing Manager, Borderless Networks, at Cisco Systems, joins me to talk about the fundamental change PoE is taking, thanks to Cisco’s UPOE solution.

The problems of network configuration changes required when virtualization operations managers need to move a VM between subnets are well documented. There are virtual networking options to solve this problem such as building very large flat networks, tunneling between subnets, and now a standard approach called VXLAN. VXLAN is a special encapsulation mechanism that runs between virtual switches and enables VMs to be deployed and moved on or between any server within the network. VXLAN requires no changes to the underlying IP addressing architecture and should require no major changes to installed infrastructure in the data center. Ken Duda Founder and Vice President, Software Engineering at Arista Networks joins me to discuss VXLAN, the first major protocol of virtual networking.

On Tuesday Auguest 16th a week before HP’s news of potentially exiting the PC business, Zeus Kerravala, Senior VP of Research at the Yankee Group and Andre Kindness Senior Analyst at Forrester Research joined me in a round table discussion to reflect on HP Networking. We assess HP Networking’s progress since it announced the acquisition of 3Com back in Nov of 2009 and its prospects for the future. In a word our mutual assessment is disappointment with major short and long-term threats from Huawei. But there is hope for the future if HP can create a bold new vision for the industry and execute it. If you are going to listen to one podcast this year about HP, this should be it.

Avaya has expanded its cloud networking product portfolio with the Virtual Services Platform or VSP 7000, a 10GbE Top of Rack (ToR) Switch and its new Virtualization Provisioning Service or VPS management software.
The VSP 7000 boasts a multi-Terabit Fabric capable of horizontally stacking many 7000s, offering a new approach to server connections. The VPS virtualization management application provides visibility and automated control of virtualized infrastructure. VPS is designed to provide NetOps and SysOps shared visibility of physical, logical and now virtual IT assets. Dan DeBacker, Director of Data Solutions Architecture at Avaya, discusses the new VSP 7000 plus VPS and the new data center design options they afford.

In Cisco’s Data Center Fabric, it has delivered a set of features and innovations that solve some of the most difficult networking challenges found in virtualized infrastructure. IP address and VM mobility plus adapter and VM Fabric EXtenders (FEX) offer increased support for virtualized data center infrastructure, offering designers flexibility to move virtualized assets independent of location. These innovations are proposed by Cisco that promises virtualization aware networking, lower cost and increased performance. Omar Sultan, Senior Manager, Data Center Architecture at Cisco Systems, and I discuss Cisco’s new data center virtualization tools.
