Supporting mission-critical applications requires 24×365 always-on infrastructure, and the Avaya Virtual Services Platform 7000 delivers against this challenge. It is a highly strategic product that is fit-for-purpose for today’s connectivity requirements and future-ready for the evolving and emerging application-driven needs of tomorrow. This paper describes Avaya’s unique distributed ToR approach to lower latency for increasingly dominant east-west traffic flows within data center and cloud computing facilities.

In Lippis Report 172, I mentioned three huge trends that are starting to interact with each other creating a perfect storm that is gripping the tech industry. One of those trends is the creation of a software ecosystem in the networking market, thanks to the Clean Slate program out of Stanford University that has spawned the Software Defined Network (SDN) initiative and open controller protocol called OpenFlow. I spent a week in the Valley talking to people at Stanford and many industry executives from Cisco, Juniper, Marvell, Big Switch, Nicira, Arista, IBM and others. In this Lippis Report Research Note, I share with you what I learned. OpenFlow-based SDN is being both hyped and in its current state, limited, but it does represent a new paradigm that has the industry abuzz, filled with possibilities.

Three strong trends are taking shape that are so powerful they threaten the status quo of the networking industry. These trends are more like storms than new markets; in fact they represent a major industry discontinuity. The first storm is happening now and is represented by merchant silicon for 10 and 40 GbE chips lowering the barrier of entry for new entrants in the Ethernet switch market. The second storm is much weaker but promises to be just as big, or bigger, than the first. This second storm is the creation of a software ecosystem in the networking industry, thanks to initiatives such as Software Defined Networks (SDN), OpenFlow, Arista Network’s EOS Central, etc. The third storm is the paradigm shift in enterprise IT spending thanks to mobile and cloud computing. These three storms are starting to interact and feed upon each other, forming a perfect storm in the networking industry. The perfect storm is already doing damage, as all major IT firms position product portfolios to navigate through it and prepare for its aftermath of making existing networking legacy.

The data center switching market is heating up. To address the scale issues posed by mobile and cloud computing nearly every network vendor is launching its own version of a 10/40/100 GbE fabric to connect servers and storage to the internet. At the heart of this fabric is a two-tier (Fat-Tree) network made up of leaf/ToR and spine/Core switches. Here leafs connect servers and spines connect leafs while also being interconnected in a logical mesh. The protocols to create this logical mesh are based upon IS-IS link state routing, but each vendor is taking a unique approach with Cisco using its FastPath, Alcatel-Lucent and Avaya using SPB (802.1aq Shortest Path Bridging) while Brocade VDX is based upon TRILL (Transparent Interconnection of Lots of Links). Juniper recently announced QFabric but has not detailed what it’s using for logical meshing. At the center of new data center design are leaf and spine switches. In Lippis Report Research Note 166, we detailed the latest ToR switches. In this Lippis Report Research Note 167, we dive into performance and power consumption measurements plus the use of SPB of Alcatel-Lucent’s OmniSwitch 10K, a new entry into spine/core data center switching market.

During December 6-10, 2010, the Lippis Report and Ixia conducted the industry’s first 10GbE data center switching evaluation of Top-of-Rack and Core Ethernet switches at the modern iSimCity lab in Santa Clara, CA. We evaluated Alcatel-Lucent’s OmniSwitch 10K, Arista’s 7504 Series Data Center Switch, BLADE Network Technologies’, an IBM Company, IBM BNT RackSwitch G8124 and IBM BNT RackSwitch G8264, Force10 Network’s S-Series S4810, Hitachi Cable’s Apresia 15000-64XL-PSR, Juniper Network’s EX Series EX8216 Ethernet Switch and Voltaire®’s Vantage™ 6048. We are conducting a second round of test scheduled for the week of April 4-8 at iSimCity, and it is open to all suppliers of 10GbE data center switching. We learned a lot about these products, both in the lab and out. In this Lippis Report Research Note, we dive into the Top-of-Rack 10GbE switches we tested as they represent a new generation of products that exhibit low power consumption, low latency, high performance and are all based upon new single chip designs from Broadcom, Marvell or Fulcrum Micro.
