Chapter 8. Unified Fabric This chapter covers the following topics: • Unified Fabric overview • Enabling technologies • Nexus 5x00 Unified Fabric configuration • Nexus 7000 Unified Fabric configuration • Cisco MDS Unified Fabric configuration The Nexus family of switches represents a revolutionary approach to I/O within the data center referred to as Unified Fabric. Unified Fabric Overview One of the biggest trends in data centers today is consolidation, which can mean many different things. In some cases, consolidation refers to a physical consolidation of data centers where dozens or even hundreds of data centers are geographically dispersed and consolidated into a smaller number of large data centers. Consolidation can also exist within a data center where a large number of underutilized physical servers are consolidated, usually by leveraging some type of virtualization technology, into a smaller number of physical servers. Although virtualization offers many benefits, including consolidation of processors, memory, and storage, little is done to consolidate the amount of adapters, cables, and ports within the data center. In most virtualization implementations, there is actually a requirement for more adapters, cables, and ports to achieve the dense I/O requirements associated with virtualization. Data centers today contain multiple network fabrics that require discreet connectivity components to each fabric. I/O consolidation is a trend within data centers that refers to the capability to aggregate connectivity to multiple fabrics into a single or redundant pair of adapters, cables, and port. Although new technologies have emerged to enable this consolidation to occur, the concept is not new. Fibre Channel, iSCSI, Infiniband, and others were all introduced in an attempt to consolidate I/O. Although the merits or consolidation capabilities of each of these technologies might be open to debate, for one reason or another, all failed to reach mainstream adoption as the single fabric for all I/O requirements. As a consolidation technology, Unified Fabric offers several benefits to customers, including • Lower capital expenditures: Through the reduction of adapters, cables, and ports required within the infrastructure. • Lower operational expenses: Through the reduction of adapters, cables, and ports drawing power within the data center. • Reduced deployment cycles: Unified Fabric provides a wire-once model, in which all LAN, SAN, IPC, and management traffic is available to every server without requiring additional connectivity components.
• Higher availability: Quite simply, fewer adapters and ports means fewer components that could fail. Enabling Technologies Ethernet represents an ideal candidate for I/O consolidation. Ethernet is a well-understood and widely deployed medium that has taken on many consolidation efforts already. Ethernet has been used to consolidate other transport technologies such as FDDI, Token Ring, ATM, and Frame Relay networking technologies. It is agnostic from an upper layer perspective in that IP, IPX, AppleTalk, and others have used Ethernet as transport. More recently, Ethernet and IP have been used to consolidate voice and data networks. From a financial aspect, there is a tremendous investment in Ethernet that also must be taken into account. For all the positive characteristics of Ethernet, there are several drawbacks of looking to Ethernet as an I/O consolidation technology. Ethernet has traditionally not been a lossless transport and relied on other protocols to guarantee delivery. In addition, a large portion of Ethernet networks range in speed from 100 Mbps to 1 Gbps and are not equipped to deal with the higher-bandwidth applications such as storage. New hardware and technology standards are emerging that will enable Ethernet to overcome these limitations and become the leading candidate for consolidation. 10-Gigabit Ethernet 10-Gigabit Ethernet (10GbE) represents the next major speed transition for Ethernet technology. Like earlier transitions, 10GbE started as a technology reserved for backbone applications in the core of the network. New advances in optic and cabling technologies have made the price points for 10GbE attractive as a server access technology as well. The desire for 10GbE as a server access technology is driven by advances in computer technology in the way of multisocket/multicore, larger memory capacity, and virtualization technology. In some cases, 10GbE is a requirement simply for the amount of network throughput required for a device. In other cases, however, the economics associated with multiple 1-G ports versus a single 10GbE port might drive the consolidation alone. In addition, 10GbE becoming the de facto standard for LAN-on-motherboard implementations is driving this adoption. In addition to enabling higher transmission speeds, current 10GbE offerings provide a suite of extensions to traditional Ethernet. These extensions are standardized within IEEE 802.1 Data Center Bridging. Data Center Bridging is an umbrella referring to a collection of specific standards within IEEE 802.1, which are as follows: • Priority-based flow control (PFC; IEEE 802.1Qbb): One of the basic challenges associated with I/O consolidation is that different protocols place different requirements on the underlying transport. IP traffic is designed to operate in large wide area network (WAN) environments that are global in scale, and as such applies mechanisms at higher layers to account for packet loss, for example, Transmission Control Protocol (TCP). Because of the capabilities of the upper layer protocols, underlying transports can experience packet loss and in some cases even require some loss to operate in the most efficient manner.
