* * The VMware VMkernel TCP/IP networking stack provides networking support in multiple ways for each of the services it handles. ? The VMkernel TCP/IP stack handles iSCSI, NFS, and vMotion in the following ways: ? VMFS on iSCSI LUNs is a virtual machine datastore. ? VMFS on iSCSI LUNs for the direct mounting of .ISO files, which are presented as CD-ROMs to virtual machines. ? NFS as a virtual machine datastore. ? NFS for the direct mounting of .ISO files, which are presented as CD-ROMs to virtual machines. ? Migration with vMotion. ? In this section, we will discuss how to create and configure vNetwork using distributed switches. Although VMware supports the standard switch network, it is a best practice and recommendation that the distributed switch architecture be used for all virtual networking purposes including the virtual machine connections, service console connections, and VMkernel connections to the physical network for VMkernel services (such as NFS, iSCSI, or vMotion). ? The first step in setting up a network environment using distributed switches is to create a distributed switch in the Inventory Networking view of the vSphere Client using the Create vNetwork Distributed Switch wizard. ? This wizard gives you the option to add hosts, physical adaptors and automatically create a distributed port group. For each host associated with a distributed switch, you must assign physical network adapters, or uplinks, to the distributed switch. You can assign one uplink on each host per uplink port on the distributed switch. ? If you did not add hosts or create a distributed port group using the Create vNetwork Distributed Switch wizard, you can add hosts to the distributed switch by using the Add Host to Distributed Switch wizard and you can create a distributed port group using the Create Distributed Virtual Port Group wizard. ? Next, you will need to configure virtual network adapters to handle network services over the distributed switch. You can confi
