The Lippis Report

June 7th, 2011

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 Bridging Group of the IEEE worked to enhance Ethernet to support class isolation, low latency, I/O and switch virtualization, lossless traffic flows, congestion control, multi-path L2 routing, and L2 discovery and capability exchange. These new technologies are referred to as Converged Enhanced Ethernet (CEE) or Data Center Ethernet (DCE). Voltaire’s CEE switches and software offer performance requirements thanks to its scalable Ethernet fabric that lowers overall fabric costs, lowers power consumption, has greater efficiencies, and simplifies management.

This document describes the challenges inherent in traditional Ethernet solutions and how Voltaire’s scale-out Ethernet architecture effectively addresses those challenges.

Deriving a return on virtualization investments means deploying effective automation techniques that can simplify the virtualized environment while allowing a policy-based deployment model. While many network vendors have chosen a proprietary path to automate network changes, Force10′s approach is to utilize open and industry standard technologies based on the extensible and modular Force10 Operating System (FTOS), across a range of the heterogeneous Force10 switch and routers portfolio.

Server virtualization brings with it a set of network operational challenges: from configuration challenges around Virtual Machine (VM) switching to managing virtual machine mobility, to providing VM location and inventory in the network. There are few tools available to the network administrator that provides visibility, control and insight into the VM environment until now. Extreme Networks® XNVTM provides network-level visibility and control of the server VM environment in a hypervisor-agnostic manner and without requiring any changes to the server virtualization operating environment.

A typical “non-virtualized” data center has three network layers, Top-of-Rack, End-of-Row and Core switches. But virtualized infrastructure adds two additional layers—the virtual switch and blade switch—raising the number of tiers from 3 to 5. This significantly increases latency plus the number of network elements within the data center resulting in increased data center management complexity. I talk with Shehzad Merchant, Senior Director for Strategy at Extreme Networks, about Extreme’s flattening approach to data center network fabric through its DirectAttach.

Move a Virtual Machine (VM) from one physical server to another, and network port profile, VLANs, security settings, etc., have to be reconfigured. Many networking companies haven’t taken the critical step of giving complete visibility and control of the VM lifecycle from an infrastructure perspective. But with XNV, Extreme Networks is bringing this functionality and visibility to network administrators, tracking VMs and applying policy as they move throughout the network. Shehzad Merchant, Senior Director for Strategy at Extreme Networks, joins me for a discussion about Extreme’s approach to network automation and visibility of virtualized infrastructure through its XNV software module.

A typical “non-virtualized” data center has three network layers, Top-of-Rack, End-of-Row and Core switches. But virtualized infrastructure adds two additional layers; the virtual switch and blade switch, raising the number of tiers from 3 to 5. This significantly increases latency plus the number of network elements within the data center resulting in increased data center management complexity.

Extreme Networks® Direct AttachTM eliminates the virtual switch layer, simplifying the network and improving performance. Extreme Networks high density BlackDiamond® 8800 series switches with 8900-series modules further enable data center simplification by utilizing high density blades and cabling to eliminate the blade switch, thereby reducing the number of tiers in the data center from 5 to 3.

A number of independent trends are driving a new age of massively scalable data centers. One of these trends include a new IT delivery model based upon cloud computing, where large hosting facilities provide a range of IT services to corporations and governments. Further, high performance computing (HPC) facilities built via server clusters on the order of thousands to tens of thousands of servers and more has ushered in new favorable economics, thanks to its use of x86 commodity hardware. The growth of public hosting and HPC facilities will only continue as efficient data center economics point to a fewer number of highly dense sites. It is this data center market segment, where the number of servers per facility is greater than 5,000, that we focus this white paper from a perspective of fabric, connecting servers and storage to internet/intranet via high performance Ethernet networking. For IT architects and designers of high-end data centers, this is the most important network design paper you will read this year.

Extensibility is a system design principle where the implementation of the operating system takes into consideration future growth. It is a systemic measure of the ability to extend the operating system and the level of effort required to implement the extension. Extensions can involve the addition of new functionality or the modification of existing functionality.

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.
