3 Intr oduction Fibre Channel over Ethernet (FCoE) technology en ables convergence of storage and LAN networks in enterprise data centers. The key benefits of FCoE in clude cost savings and improv ed operating efficiencies, but the technology is new and deployment configur ations are less well under stood than proven Fibre Channel solutions. Server[...]

Network convergence, enabled by FCoE, helps addres s the network infrastructure sprawl while fully complementing server consolidation efforts and improv ing the efficiency of the en terprise data center. Benefits of FCoE Enabled Netw ork Con v ergence An FCoE enabled converged network provides th[...]

5 • Increased IT efficiency and business agility A converged network streamlines and eliminates repe ated administrative tasks such as server and network provisioning with a “wire once” deployme nt model. The converged network also improves business agility letting data centers dynamically an d rapidly respond to requests for new or expanded [...]

7 Servers supporting PCI Express (x8 or higher) will be able to utilize the full potential of the Emulex LP21000’s 2x10Gb/s Ethernet interfaces, balancing both storage and networking I/O requirements. The priority flow control prevents degradation of traffi c delivery and enhanced transmission selection enables partitioning and guaranteed service[...]

8 Con verg ed Networking with FC oE in an ESX En vir onment Server virtualization is one of the key drivers of FCoE deployment . FCoE enabled network convergence significantly reduces the number of cables, switch ports and adapters as show in Figure 6. Figure 6 : Effects of Convergence using a CNA in a Rack-mount Server running ESX The following se[...]

9 machines hosted on the ESX server. The configuration and manageability of the ESX server is performed by VMware vCenter® Server (typicall y residing on a separate management server). Figure 7 : The hypervisor/VMKernel views the CNA as an HBA and a NIC When an Emulex LP21000 CNA is installed on an ESX server, the adapter is visible in the vCenter[...]

11 IT organizations can also leverage the Emulex Virtual HBA technology, based on the ANSI T11 N_Port ID Virtualization (NPIV) standard. This virtualization tec hnology allows a single physical CNA or HBA port to function as multiple virtual ports (VPorts), with ea ch VPort having a separate identity in the Fabric. NPIV support began with ESX Serve[...]

12 In this configuration, even in the extreme case of a CNA failure, the links for storage and networking can be immediately failed over with no interruption to applications. Within ESX, multipathing can be configured from th e configuration tab by selecting storage, followed by selecting properties for the appropriate data store. From the data sto[...]

13 Configuring the LP21000 as a Network Adapter Upon installation, the LP21000 appears as a 10 Gigabi t NIC in th e Configuration Tab’s network adapter view, as shown in Figure 13 where two LP21000s appear s as two 10 Gigabit network adapters (also shown are two 100 Mbps NICs which are built into the server motherboar d.). Figure 13 : Two LP21000[...]

14 Configuring the LP21000 for NIC Teaming in ESX NIC teaming occurs when multiple up link adapters are associated with a single vSwitch to form a team. A team can share the load of traffic between physical and virtual networks or provide passive f ailover in the event of a hardware failure or network outage. Figure 14 shows the configuration of tw[...]

15 Unified management of Emulex Fibre Channel HBAs and CNAs • VPort monitoring and configuration • Online boot from SAN configuration • On-line WWN management • Flexible, customizable reporting capability The availability of graphical user interface (GUI) and command l ine interface (CLI) options provides greater flexibility with HBAnyware.[...]

16 Conclusion Server virtualization has been one of the key drivers of converged networks in the data center. A converge d network fully complements server virtualization and enables the roll out of on -demand se rvices where applications and network services are provisioned on the fly. Fibre Channel over Ethernet technology enables network converg[...]
