Chapter 16 Working with DatastoresIn an L3 environment the following restrictions apply:• The environment does not support VMware Site Recovery Manager.• The environment supports only NFS protocol. Do not use other <strong>storage</strong> protocols such as FCoE over thesame physical network.• The NFS traffic in this environment does not support IPv6.• The NFS traffic in this environment can be routed only over a LAN. Other environments such as WANare not supported.• The environment does not support Distributed Virtual Switch (DVS).Creating DatastoresDepending on the type of <strong>storage</strong> you use and your <strong>storage</strong> needs, you can create a VMFS or NFS datastore.You use the new datastore wizard to create your datastores. You also use this wizard to manage VMFSdatastore copies. For information, see “Managing Duplicate VMFS Datastores,” on page 141.Create a VMFS Datastore in the vSphere Web ClientVMFS datastores serve as repositories for virtual machines. You can set up VMFS datastores on any SCSIbased<strong>storage</strong> devices that the host discovers, including Fibre Channel, iSCSI, and local <strong>storage</strong> devices.Prerequisites• Install and configure any adapters that your <strong>storage</strong> requires. Rescan the adapters to discover newlyadded <strong>storage</strong> devices.• Browse to Datastores in the vSphere Web Client navigator.
