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. 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. 5.3.5 VMware ESXi: Preparing for iSCSI attachment Figure 5-18 FC WWPNs in VMware vSphere Client 236  Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.2.1
