The key benefits of FCoE include cost savings and improved operating efficiencies, but the technology is new and deployment configurations are less well understood than proven Fibre Channel solutions. Server virtualization using VMware ESX enables consolidation of server resources by allowing multiple virtual machines to exist on a single physical server. This level of consolidation increases the demand for I/O bandwidth and the need for multiple I/O adapters. FCoE-based converged networking addresses the requirement for increased bandwidth while significantly simplifying the I/O infrastructure. This deployment guide presents information about network convergence using FCoE technology and also provides an overview of how to realize the maximum benefits from network convergence using FCoE technology in an ESX Server environment. Drivers of Network Convergence Enterprises rely on their computing infrastructure to provide a broad array of services. As enterprises continue to scale their computing infrastructure to meet the demand for these services, they inherently face an infrastructure sprawl fueled by the proliferation of servers, networks and storage. This infrastructure growth typically results in increased capital expenses for equipment and operating expenses for power, cooling and IT management, reducing the overall efficiency of operations. In order to overcome these limitations, the industry is moving towards empowering data centers with technologies that enable consolidation. Server virtualization and blade server technologies are helping address the consolidation of physical servers and rising rack densities in the data center. A related trend associated with server virtualization and blade server deployments is the expanded use of higher I/O bandwidth and adoption of external storage which enable consolidation and mobility. Since the late 1990s data centers have maintained two sets of networks – a Fibre Channel storage area network (SAN) for storage I/O traffic and a local area network (LAN) for data networking traffic. With the growing implementation of SANs, accelerated by the adoption of blade servers and server virtualization, the penetration of SANs is expected to grow much higher. While IT managers can continue to maintain two separate networks, in reality this increases overall costs by multiplying the number of adapters, cables, and switch ports required to connect every server directly with supporting LANs and SANs. Further, the resulting network sprawl hinders the flexibility and manageability of the data center. Figure 1: Key factors driving network convergence. Network convergence, enabled by FCoE, helps address the network infrastructure sprawl while fully complementing server consolidation efforts and improving the efficiency of the enterprise data center. Benefits of FCoE Enabled Network Convergence An FCoE enabled converged network provides the following key benefits to IT organizations: • Lower total cost of ownership through infrastructure simplification A converged network based on FCoE lowers the number of cab...
