The Lippis Report

January 29th, 2012

Computer networking vendors have been increasing the speed and port density of their Ethernet switches while reducing power draw and price per port. But while Ethernet switching hardware marches on linearly, thanks to 10, 40 and 100GbE, networking software is taking a different historical path as the pace of compute and network technology evolution has diverged, with networking lagging. Highly virtualized server deployment has broken traditional networking approaches on multiple levels, for example. In response, the industry is now developing a “virtualized infrastructure” or “stack” to add network flexibility. To close the technology gap, Software-Defined Networking (SDN) is promoted as the new “organizing principle” to deliver network software and service value. While it will be, likely, years before SDN’s organizing principles take hold, I propose that these two industry activities are inexplicably linked and phased; here’s why…

With CAPEX accounting for only 20% of the cost of a network, it is important to look beyond initial expenditures and consider TCO and the business value a network can provide. A third-party TCO comparison of a Cisco network versus other vendors illustrates that Cisco can deliver a 13% better TCO even before business benefits, such as network uptime and employee productivity are considered. Further, the Cisco Borderless Network Architecture acts as a platform for service delivery, allowing your IT organization to say “yes” to business and revenue-enhancing opportunities.

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.

Building identity and context awareness into the network is critical to implementing an effective infrastructure.
Major topics include:

● What policies are and who implements them
● Changing network dynamics and problematic new technologies
● Important challenges to implementers
● Characteristics of a Policy-Governed Network architecture
● Policy-implementation platform: the Cisco® Identity Services Engine
● Scenarios showing how policies can address specific network issues
● How to begin transitioning to a Policy-Governed Network

It can be easy to forget how much depends on the enterprise network—until you have to tell the VP of sales that he can’t use his iPhone on the corporate network because the appropriate security controls aren’t in place. Or you must tell the CIO that expanding the virtualization initiative to include business-critical applications will severely tax bandwidth. The truth is, nearly everything in modern businesses is dependent on the enterprise network, and every decision you make is based on whether the network can handle it. This paper takes a look at a common pitfall in IT circles that can have a serious impact on the IT decision maker’s ability to say “yes” to new business initiatives. It also offers recommendations for IT organizations that wish to act as business enablers.

A third-party business consulting firm analyzed the total cost of ownership (TCO) of Cisco enterprise customer networks, and contrasted that TCO to “good enough” networks from other networking vendors. Key findings:
1) TCO is a better metric than CapEx to assess network cost because it considers the full impact on IT spend, including CapEx, services, labor, bandwidth and energy.
2) The Cisco Borderless Network Architecture can deliver up to 13% better TCO than a “good enough” network, offering compelling value for the strategic Cisco investment.
3) Even if architectural benefits are discounted in the analysis, Cisco is, at most, a 7% TCO premium over other vendors due to IT labor savings and extended product lifecycles from Cisco solutions.
4) The single biggest benefit of Cisco’s architectural approach is labor savings. Labor constitutes 50% of TCO and Cisco delivers 5% to 10% labor savings driven by unified wired and wireless and embedded security.
5) A quality network delivers business benefits beyond TCO, including improved network uptime, higher user productivity and a lower threat of security breaches.

By all counts, Cisco’s upgrade of the Catalyst 6K via its new Supervisor 2T, or Sup2T, is its most ambitious and thoughtful yet for the venerable platform. The Sup2T is a 2 Terabit (Tb) platform that triples the previous Sup720 performance. Thanks to the support of Virtual Switching System (VSS), the platform allows two 2 Tbps switches to combine into a single 4 Tbps virtual switch. The Sup2T is a major upgrade to the most widely-deployed switching platform in campus and data center networking in the industry. But while these performance numbers are impressive, it’s the new Cat6K’s network services and pricing that deliver most of the value. From a services’ point of view, the Cat6K stands alone.

Enterprise workspace is quickly evolving with new networked devices to improve communication, collaboration, security and productivity. Power over Ethernet (PoE), a way to deliver electrical power over LAN cabling to networked devices, has been widely deployed over the years to provide power to various endpoints. Cisco® Catalyst® 4500E, a market leader of PoE technology, continues to innovate to deliver Universal PoE (UPOE) technology with up to 60 watt power to enable even broader endpoint support, with additional benefits of higher availability, lower OpEx and faster deployment.

This paper provides an overview of the Cisco UPOE technology. It describes how Cisco has evolved PoE technology to UPOE, the use case examples of UPOE to simplify enterprise deployment, and UPOE architecture and operations.

Hundreds of Cisco customers have debated the trade-off of prioritizing the lowest price for a point product or service in their network over a strategic plan for how they architect their network infrastructure. Through interactions with many customers, Cisco has analyzed various network designs and implementations. Our findings show that although there is a place for building a low-cost tactical network, the ongoing operations, upgrades and lack of preparedness to meet new business challenges prove to be hindrances to organizations in the long run. Rather than just considering capital cost, organizations are well served to look at total cost of ownership, including operations and return on investment plus business capabilities enabled by a strategic network, as they build out their networks to address business needs today and tomorrow. Forrester Consulting Group provides an excellent analysis in this paper too.

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.
