machines hosted on the ESX server. The configuration and manageability of the ESX server is performed by
VMware vCenter® Server (typically residing on a separate management server).

When an Emulex LP21000 CNA is installed on an ESX server, the adapter is visible in the vCenter
Configuration Tab in the storage adapter view as well as the network adapter view. When deploying
multiple CNAs for failover and load balancing, both Fibre Channel multipathing and NIC teaming must be
configured on both CNAs.
Upon installation, the LP21000 appears as a storage adapter similar to that of a HBA (see Figure 8). The
LP21000s are each associated with a standard 48-bit Fibre Channel WWN (World Wide Name) and all
LUNs visible to that adapter are displayed in the details area for the selected LP21000. LUN masking and
zoning operations, required for LUN visibility, are carried out similar to configuring a Fibre Channel HBA.
