Note:  Beginning with VMware ESXi version 5.5, certain new features can be accessed through the vSphere Web Client only. However, we do not demonstrate any of these features. All of the following examples continue to focus on the use of the desktop client. 

Connect to the ESXi server (or VMware vCenter) by using the VMware vSphere Client and browse to the Configuration tab. Click Storage Adapters  to see the HBA WWPNs, as shown in Figure 5-18.

After all of these steps are completed, the ESXi host is prepared to connect to the Storwize V5000. For more information about creating the ESXi FC host in the Storwize V5000 GUI, see 5.5.1, “Creating FC hosts” on page 258. 

## 5.3.5 VMware ESXi: Preparing for iSCSI attachment 

This section describes how to enable iSCSI on VMware ESXi hosts. We focus on vSphere because the complete iSCSI stack was rewritten in this level. This level offers improved performance and supports useful features, such as jumbo frames and Transmission Control Protocol (TCP) Segmentation Offload. We focus on the basic ESXi iSCSI setup. 

For more information, see the VMware vSphere Documentation Center, which is available at this web page. 

For more information, see VMware Compatibility Guide . 

Important: For converged network adapters (CNAs) that support both FC and iSCSI, it is important to ensure that the Ethernet networking driver is installed in addition to the FCoE driver. The Ethernet networking driver and the FCoE driver are required for the configuration of iSCSI.
