vSphere Storage Figure 1-3. iSCSI Storage iSCSI HBA virtual machine Host VMFS iSCSI array virtual machine software adapter ethernet NIC LAN LAN In the left example, the host uses the hardware iSCSI adapter to connect to the iSCSI storage system. In the right example, the host uses a software iSCSI adapter and an Ethernet NIC to connect to the iSCSI storage. iSCSI storage devices from the storage system become available to the host. You can access the storage devices and create VMFS datastores for your storage needs. For specific information on setting up the iSCSI SAN, see Chapter 8, “Using ESXi with iSCSI SAN,” on page 61. Network-attached Storage (NAS) Stores virtual machine files on remote file servers accessed over a standard TCP/IP network. The NFS client built into ESXi uses Network File System (NFS) protocol version 3 to communicate with the NAS/NFS servers. For network connectivity, the host requires a standard network adapter. NOTE ESXi does not support the delegate user functionality that enables access to NFS volumes using nonroot credentials. NFS Storage depicts a virtual machine using the NFS volume to store its files. In this configuration, the host connects to the NFS server, which stores the virtual disk files, through a regular network adapter. 14 VMware, Inc.
Figure 1-4. NFS Storage Host virtual machine NFS ethernet NIC LAN NAS appliance Shared Serial Attached SCSI (SAS) Stores virtual machines on direct-attached SAS storage systems that offer shared access to multiple hosts. This type of access permits multiple hosts to access the same VMFS datastore on a LUN. Target and Device Representations In the ESXi context, the term target identifies a single storage unit that the host can access. The terms device and LUN describe a logical volume that represents storage space on a target. Typically, the terms device and LUN, in the ESXi context, mean a SCSI volume presented to the host from a storage target and available for formatting. Different storage vendors present the storage systems to ESXi hosts in different ways. Some vendors present a single target with multiple storage devices or LUNs on it, while others present multiple targets with one LUN each. Figure 1-5. Target and LUN Representations target LUN LUN LUN storage array target target target LUN LUN LUN storage array Chapter 1 Introduction to Storage In this illustration, three LUNs are available in each configuration. In one case, the host sees one target, but that target has three LUNs that can be used. Each LUN represents an individual storage volume. In the other example, the host sees three different targets, each having one LUN. VMware, Inc. 15
