Deployment Guide: Network Convergence with Emulex LP21000 CNA and VMware® ESX Server How to deploy Converged Networking with VMware ESX Server Using Emulex FCoE Technology.

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.
4 Figure 1: Key factors driving network convergence. 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.
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.

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.
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.
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).

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.
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.
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.
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.
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.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Emulex LP21000 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Emulex LP21000 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Emulex LP21000 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Emulex LP21000 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Emulex LP21000, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Emulex LP21000.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Emulex LP21000. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Emulex LP21000 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
