A Comprehensive Approach to Corporate and Government Energy Cost Savings and Carbon Reduction

Being green is increasingly being forced upon IT business leaders from their management, government regulations and societal pressures. Ask a recent college grad what is the number one societal contribution they would like to make with their career and the answer is “make the world greener.” The workforce is changing worldwide with a sense of personal and corporate social responsibility to reduce carbon emissions, and choose sustainable materials and processes to power our lives and deliver products and services. And being green is no longer a luxury that IT leaders can choose as governments, boards of directors and presidential directives issue mandates forcing energy efficiency upon IT executives.

One significant trend that has emerged during the current business/economic cycle is that IT projects that reduce cost are winners. This savings trend is as strong as I have experienced in my twenty-five years within the IT industry. In particular, it’s propelling data center consolidation, server virtualization and mobile computing projects. As enterprises consolidate data centers and miniaturize them with virtualization, cloud-computing providers are busy offering a new lower cost IT delivery economic model. In short, a new tier of computing has emerged were endpoint devices are mobile and applications are delivered via corporate data centers and cloud computing facilities. This new model of computing that also increases convenience and productivity is lacking in one important area; network security for both mobile endpoints and the ability of data center security appliances to keep up with application demand.

Major IT Delivery Transitions IT Business Leaders Are Managing
Application owners and developers have been deploying and writing applications as if networks had no boundaries or were borderless. By “application owners” I mean IT departments chartered with IT application delivery and management. By “application developers” I mean in-house corporate software developers, independent software vendors (or ISVs) and software companies. There has always been a disconnect between applications and network architects where developers write applications to run over a network as long as there is connectivity. In addition, service-oriented architecture (SOA) based applications call for greater application componentization, which increases messaging between application components, resulting in the network having a direct impact on application performance. In essence, application owners, developers and application standard bodies assume that networks are borderless as the industry is organized around the OSI model where knowledge and skills at one layer, e.g., the network is not necessarily taken into account at another layer, i.e., the application. Therefore, the normal state of affairs is that network designers have been tasked to optimize applications to improve user experience especially when the application was not written to run over a particular kind of network. This status quo does not scale and needs to be re-thought.

Networking is entering a new phase or era. During the 1990s, new networking markets opened up, creating multi-billion dollar opportunities for the vendor community and corporate cost savings for IT business leaders. First, it was shared LANs and routing, then switched LANs, then Frame Relay to speed up WANs, then SNA over IP, then remote access via dial-up and VPN, then MPLS, then IP telephony, then Wireless LANs etc… and now, it’s video and cloud networking. You get the picture. But what we didn’t realize as we build these networks is that they are silos with disparate management systems and unique access methods resulting in operational cost overlap and, most importantly, user frustration as they transition application use from desktop, to mobile end point, to remote endpoint. In short, we built boundaries around applications in the form of networks and it is the dismantling of these borders that vendors are now starting to deliver and differentiate upon. It’s not just Cisco that communicates borderless networks, but HP Networking, Juniper, Brocade, Extreme, Avaya, Force10 and others too. Why is the industry entering a new age of borderless networking and what’s in it for IT business leaders, is explained in this Lippis Report Research Note.

It hasn’t been since the mid 1990s that the networking industry was focused on multi-protocol integration or convergence. But the industry is gearing up for a major innovation and competitive cycle fueled by the multi-billion dollar addressable market for data center network fabrics. Over the last eighteen months, every major Ethernet infrastructure provider has been talking about two and three tier network fabrics for high-end data centers.

Companies such as Cisco, Arista Networks, HP/3Com, Force10, Voltaire, Extreme, Brocade, Juniper et al have announced network fabrics for data centers with five thousand and more servers with and without storage enablement. Juniper talks of a one-tier fabric through their Project Stratus work with IBM to be available some time in the future. Brocade recently introduced its Brocade One, which is a converged data center fabric. Extreme Networks launched its DirectAttachTM that eliminates virtual plus blade switch layers. HP has FlexFabric, a virtualized fabric for the data center. Cisco launched its FabricPath Switching System or FSS for the Nexus 7000 that enables massive scale of a two-tier fabric.

In this Lippis Report Research Note, we review the architectural attributes of two tier network fabrics.

Networking has become “rigid”. Yes I know it’s almost absurd to attribute inflexibility or rigidity to networking. Look what TCP/IP has done for us. There are nearly 2 billion people connected to the internet and according to the Internet World Stats internet user growth rate increased by 380% between 2000-2009. With 2 billion people and growing online, accessing a plethora of applications via a wide range of end-points there is no doubt that the internet and TCP/IP has been a much bigger success than anyone would have imagined back in the early ’90s. But there’s always a give and take between computing and networking where one drives and changes the other. Right now we are in a compute innovation cycle that’s driving a fundamental change in networking which screams out the need for more flexibility.

In Lippis Report 151: A Two or Three Tier High-End Data Center Ethernet Fabric Architecture? we detailed the new two tier data center Ethernet fabric that is becoming conventional wisdom amongst business leaders of high end data centers and cloud computing service providers. The networking industry is headed for a major innovation and competitive cycle fueled by a multi-billion dollar addressable market for data center network fabrics. Over the last eighteen months, every major Ethernet infrastructure provider has announced or taken a position on two tier network fabrics for high-end data centers. Companies such as Cisco, Arista Networks, Force10, Voltaire, HP/3Com, Juniper, Extreme, Brocade, BLADE Network Technology, et al have announced network fabrics for data centers with two thousand and more servers that either support storage enablement or not. In this Lippis Report Research Note, we review why it is Ethernet that will be the network fabric of high performance computing or HPC and cloud computing deployments.

In the Lippis Report Research Note 150, we discussed the new industry group called Unified Communications Interoperability Forum or UNIF and compared it to other industry consortium charted to deliver interoperable solutions. While interoperability is sorely needed in the UC industry, it looks like Microsoft killed its changes of broad industry success before it started. What I hear from both UCIF members and non-members is that UCIF is controlled by Microsoft, and thus, lacks a large cross section of industry players as well as major UC providers. With its current structure, UCIF will make limited headway on its charter. In this Lippis Report Research Note, we review UCIF and its’ opportunities.

In mid May of this year HP, Juniper Networks, Microsoft, Logitech / LifeSize and Polycom established a forum to develop a set of interoperability test methodologies and certification programs along with specifications and guidelines that enable mixed vendor Unified Communications UC solutions to work with each other. In short, the UC Interoperability Forum or UCIF is trying to define what it means for multi-vendor UC implementations to interoperate. Since its establishment, membership has grown by thirteen vendors, but blaringly obvious is the omission of Cisco, Avaya, Mitel, ShoreTel and other major UC providers. This begs the question of motivation. Is the UCIF interested in interoperability or changing the market landscape to gain advantage on the established leaders? In this Lippis Report Research Note we explore this question.

In Lippis Report 148 we reviewed the major drivers and trends that are propelling the high-end data center Ethernet switch market to well over a $1B annual run rate. In this Lippis Report Research Note, we review the major suppliers of these switches. We review Cisco, Arista Networks Force10 Networks, BLADE Network Technologies, HP/3Com/H3C, Voltaire, Avaya, Brocade, and Juniper and identify their unique positions and offerings to participants in the burgeoning market. Our focus is the high-end, high density 10GbE switches that are enabling virtualized cloud computing data centers thanks to Terabits per second of back plane switching capacity, billions of packets per second of layer 2/3 forwarding, hundreds of 10GbE port connectivity per chassis, a new two-tier architecture, microsecond level latency, low power consumption, non-stop operation and software hooks that eliminate network barriers to large scale server virtualization. The engineering in these switches should be celebrated, as they represent the state-of-the-art in computer and network design. In short, they represent the fundamental building block of a new generation of IT delivery based upon cloud computing and virtualization. This Research Note is a must read for any IT executive designing a data center.

After finishing this Research Note, it became evident that this market needs a set of industry neural 10GbE switch test to independently verify vendor claims. We hope to make such a contribution this Fall.

During last week’s Cisco Q3 FY10 quarterly financial conference call, John Chambers, Cisco’s CEO, said something that impressed and shocked me. The company has been quiet about the growth rates for its Nexus line of data center switches until this call. What shocked me was that the Nexus 7000 is now on an annualized run rate of $1B, yes that’s Billion with a B! I remember being interviewed by John Markoff of the NY Times in Jan ’08 about the Cisco’s Nexus and Juniper’s yet to be announced Ethernet switches. In just 27 short months, the Nexus product line including the 7000, 5000 and 2000 represents a $1.4 B run rate of revenue to Cisco. Another insight gained from this ramp up is that the data center networking trends that we’ve discussed here in various Lippis Report Research Notes are powerful demand drivers for Cisco and other companies participating in this lucrative emerging market and its just starting! Companies such as Arista Networks, Force10 Networks, Blade Network Technologies, HP/3Com/H3C, Voltaire, Avaya, Brocade, Juniper, et al, have unique positions and offerings to participants in the burgeoning market. In this Lippis Report Research Note, we review the mega trends driving high market growth. We save a product review of each of the suppliers for our next Lippis Report Research Note.

This past Interop in Las Vegas was one of the best I have attended, since even before the economy took a noise dive in 2008. The tone and level of excitement of the industry’s growth potential was refreshingly up beat from the hundreds of IT and vendor executives I talked with. While the size of Interop is a small fraction of what it was in the late 1990s, (70k attendees with over 600 exhibitors to ~ 15K attendees with ~ 200 exhibitors) it still provides a pulse of the networking industry. In fact, Interop has come full circle, back to being a networking event even though it has added other topics. You have to give Dan Lynch credit for creating such a long lasting venue for our industry. Congratulations to Cisco, Arista Networks, HP/3Com, Mallonx for winning best of show in their respective categories and for Arista for winning Best of Interop. In this Lippis Report Research Note I provide the key industry themes that were evident at Interop this year.

During a podcast with Zeus Kerravala of the Yankee Group, we came to the conclusion that the unified communications market is in a funk and the only way out is for suppliers to adhere to industry standards that allow interoperability. To demonstrate this achievement, UC providers would be well advised to participate in industry wide interoperability testing. In this Lippis Report, we discuss the issues that are holding back UC and video conferencing adoption.
