The Lippis Report

July 27th, 2010

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.

Massively scalable data centers have unique requirements such as low latency, high performance, non-stop operation, simplicity of design, workload mobility and storage transport support. To address these requirements Cisco launched FabricPath, which is a scalable multi-link and multipath technology allowing 2 to 48 Nexus 7000s to be configured in a large, non-blocking Ethernet switch fabric. This fabric, called a FabricPath Switching System or FSS, eliminates oversubscription and creates a two-tier fabric. In addition to FabricPath, Cisco launched its’ F-Series 10GbE module for the Nexus 7000, which offers 32 ports of auto-sensing 1/10GbE targeted at server access, aggregation and FCoE implementations solutions. Craig Griffin, Senior Director of Product Management for Cisco’s Nexus 7000 discusses new Ethernet innovations for the age of massively scalable data centers.

A white paper on the topic is available here:

It hasn’t been since the mid 1990s that the networking industry was focused on multi-protocol integration or convergence. 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. Cisco just 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 and three tier network fabrics and review FSS and its accompanying F-Series 10GbE module.

Unified communications is becoming an integration point for traditional dial tone, FAX, video and messaging as it adds increased access and functionality to these important forms of communications. Sagemcom is by far the industry leader in IP FAX, having successfully integrated FAX capability into Cisco, Avaya, Alcatel-Lucent and Microsoft’s UC platforms.  Its’ XmediusFAX has proven to reduced cost, increase access and security of FAX communications.  In this Lippis Report podcast, I talk with Bob Wood, Executive Director at Sagemcom, about how FAX communications can be integrated into the UC platform of your choice and the business outcomes it delivers.

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.

Networking has become “rigid”. Yes, I know it’s almost absurd to attribute inflexibility or rigidity to networking, but we are in a compute innovation cycle that’s driving a fundamental change in networking, which screams out the need for more flexibility and configuration automation. The well understood problem is that when a virtualized machine is moved from one physical machine to another, the network, load balancers, firewalls/IPS, broadcast domains, etc., have to be reconfigured. There is no automation in place, meaning that the network is not flexible or agile enough to make the changes required. Networking companies such as Force10 Networks are driving an open approach to automation to enable network changes. I spoke with Steve Garrison, Vice President Marketing for Force10 Networks about their “Open Automation” approach to networking. Enjoy, Nick

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.

With so many potential points of contact: desk phones, soft phones, voice messaging, e-mail, video conferencing, texting, social media, mobile devices etc., how can we ever actually be reached within a reasonable timeframe? How does UC transform an organization’s communications infrastructure, improve efficiency, optimize work processes, and provide for business continuity and compliance? To find out, in February and March 2010, Aberdeen Group surveyed 184 organizations in more then 28 countries around the world. This paper is the result of that effort.

While the networking industry is full steam ahead with the transition from 1 to 10 Gb Ethernet in corporate uplinks plus virtualized and cloud spec data centers, the IEEE has been working on 40 and 100Gb Ethernet standards to be ratified soon. It’s anticipated that the 40GbE standard will be completed first and built with lower cost, long-range optical components than 100GbE. The question on the minds of most IT business leaders is when and where to deploy these ultra high-speed Ethernet technologies and at what cost? We answer these questions with Steve Garrison, Vice President, Marketing of Force10 Networks. We’ll dive into Force10’s 40 GbE leadership position and the new network design options it unleashes upon IT business leaders.

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.

WAN optimization products are central to delivering excellent application performance to employees in branch offices especially as applications continue to be centralized in data centers.  Another key attribute of WAN optimization is that these solutions reduce WAN bandwidth requirements thus spend.  At the heart of WAN optimization technology is cache architecture, or how device stores or caches data to minimize WAN transfers.  We dive into the two main cache architecture approaches; “per peer” and “universal” then ask the key question.  Does caching architectures and cache sizing affect WAN optimization performance or are there other more important aspects of WAN optimization that buyers should be concerned with as they undergo vendor selection”?  In this Lippis Report podcast, I talk with Baruch Deutsch, Senior Director of Product Marketing at Cisco Systems, to demystify WAN optimization.
