nicklippis.jpg
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.

Multi-Chassis Link Aggregation

Get the White Paper

May 31st, 2010

By Arista Networks

For many years, networks have been oversubscribed. Such oversubscription was tolerable in enterprise networks as the applications were not bandwidth intensive, but not anymore. In a datacenter, the primary reason for this oversubscription is insufficient uplink bandwidth from each rack. Each top-of-rack switch is typically connected to two aggregation switches for redundancy. However, half the uplinks are blocked by spanning tree to avoid loops in the network; this reduces the available bandwidth between the rack and aggregation layer of the network by 50%. Arista’s Multi-Chassis Link Aggregation (MLAG) feature removes this bottleneck and allows the utilization of all interconnects.

Managing The Transition To Software Centric Communications

Get the White Paper

May 31st, 2010

By GreenSpring Partners

New communications capabilities have been introduced over the past decade which permit the integration of multi-modal communications (voice, fax, email, and instant messaging, to name a few) within the fabric of modern corporations. Specifically, the opportunities for integration have come in three waves. The first, which is well under way, is the replacement of stand -alone digital voice systems with new communications systems that integrate voice traffic into the IP corporate network. The second wave is the integration of diverse communication applications into a unified communications framework. Formerly, stand -alone applications can integrate with each other and permit users to tap the productivity enhancements of staying connected no matter which device or which communication mode is being used. The third wave is to take advantage of standards based communications applications and interfaces to integrate communication applications into core business processes and applications.

This White Paper reviews the growing risks associated with staying in the digital communications environment, and the opportunities and services support available for making the migration to converged IP Network unified communications. Download it now.

Meet the Challenge of Scaling Application Performance for the Global Organization

Get the White Paper

May 31st, 2010

By Cisco Systems

Typically, data centers have been built over time, with servers added as they are needed. This process has resulted in server sprawl, increasing power and cooling costs, and created challenges in management and security. To meet their requirements, organizations are employing virtualization on a broad scale on servers centralized in the data center. However, server platform and virtualization address only one part of the problem for the global organization. Not only does application complexity put a burden on the server resources, but applications increase the burden on the WAN. With a widely distributed user base, organizations must address the challenge of WAN performance if they are to deliver applications to remote users with an acceptable user experience. To meet this challenge, Cisco provides a solution to host applications and deliver them over the WAN while helping ensure the highest levels of scale and performance, enabling organizations to achieve their business initiatives.

Lippis Report 148: What’s Driving The Multi Billion Dollar Data Center Ethernet Market

May 17th, 2010

nicklippis.jpgDuring 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.

The Role of 10 Gigabit Ethernet in Virtualized Environments

Get the White Paper

May 17th, 2010

By Cisco Systems

Virtualization is rapidly becoming an essential tool for more fully harnessing and managing the power of today’s data center servers. In only a few years, standard x86 server technology has increased in performance and density so that today, multisocket, quad-core systems with 32 or more gigabytes of memory, are the norm. The combination of multicore computing and virtualization software such as VMware Virtual Infrastructure has enabled IT departments to bring server sprawl under control by running multiple independent workloads on a smaller number of servers. Today, fewer servers are required to do the same work, and their utilization levels have increased — both factors that contribute to greater energy efficiency and lower power and cooling costs.

As IT departments have discovered the benefits of server consolidation, they have also found that virtualization solves an even broader set of problems. Business continuity plans based on virtualization can make disaster-recovery solutions simple, reliable, and more cost effective. Virtual desktop environments can use centralized servers and thin clients to support large numbers of users with standard PC configurations that help to lower both capital and operating costs. Virtualization allows development, test, and production environments to coexist on the same servers, and it helps decouple application deployment from server purchasing decisions. New applications can be deployed in virtual environments and scaled on demand to accommodate the evolving needs of
the business.

Cache Architecture In WAN Optimization: It’s Not The Only Criteria in Vendor Selection

Listen to the Podcast

May 17th, 2010

Baruch photo1WAN 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.
