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.

The fundamental nature of data center computing is rapidly changing. The traditional model of separately provisioned and maintained server, storage, and network resources are constraining data center agility and pushing budget envelopes to the limit. IT organizations recognize that these static pools of isolated resources are being underutilized, a problem that can be exacerbated when dedicated infrastructure or computer systems are used to support different classes of data center workloads. One response has been for IT organizations to adopt virtualization and blade technologies, which enable a more flexible and highly utilized infrastructure. These new, more scalable technologies can be dynamically provisioned to meet continuously evolving business requirements. At the same time, these technologies apply new pressures to the multiple networks in the data center, further worsening spend issues. And it increases the burden on the IT teams that support them.

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:

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

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. Enjoy, Nick

The standard for 10 Gigabit Ethernet (IEEE802.3ae) was ratified in 2002. While 10GbE deployments have grown every year since then, the technology has primarily been used to interconnect switches and routers. Almost all of the server connections in data centers have remained at 1 Gbps, limiting the amount of network throughput available to each server. With recent enhancements in CPU performance, system I/O, and storage I/O the gigabit network has increasingly become the application and workload performance bottleneck.
The primary reason for staying with Gigabit Ethernet has been cost-performance. Until recently it has been more cost-effective to have multiple GbE connections rather than a single 10 GbE port. In addition, most installed servers typically cannot utilize the full bandwidth of a 10 GbE connection. However both of these factors are changing, which are leading to widespread adoption of 10 GbE for server connectivity over the next few years.
Download this white paper for an overview of the factors that are driving the growth for 10 GbE in the data center.
