vSphere Storage Supported Storage Adapters Storage adapters provide connectivity for your ESXi host to a specific storage unit or network. ESXi supports different classes of adapters, including SCSI, iSCSI, RAID, Fibre Channel, Fibre Channel over Ethernet (FCoE), and Ethernet. ESXi accesses the adapters directly through device drivers in the VMkernel. Depending on the type of storage you use, you might need to enable and configure a storage adapter on your host. For information on setting up software FCoE adapters, see “Configuring FCoE Adapters,” on page 37. For information on configuring different types of iSCSI adapters, see Chapter 9, “Configuring iSCSI Adapters and Storage,” on page 67. Displaying Storage Adapters The host uses storage adapters to access different storage devices. You can display details for the available storage adapters and review their information. You must enable certain adapters, for example software iSCSI or FCoE, before you can view their information. Table 1-1. Storage Adapter Information Adapter Information Description Model Model of the adapter. Targets (Fibre Channel and SCSI) Number of targets accessed through the adapter. Connected Targets (iSCSI) Number of connected targets on an iSCSI adapter. WWN (Fibre Channel) World Wide Name formed according to Fibre Channel standards that uniquely identifies the FC adapter. iSCSI Name (iSCSI) Unique name formed according to iSCSI standards that identifies the iSCSI adapter. iSCSI Alias (iSCSI) A friendly name used instead of the iSCSI name. IP Address (independent hardware iSCSI) Address assigned to the iSCSI HBA. Devices All storage devices or LUNs the adapter can access. Paths All paths the adapter uses to access storage devices. Properties Link that indicates that the adapter requires additional configuration. iSCSI and FCoE adapters display this link. View Storage Adapters Information Use the vSphere Client to display storage adapters that your host uses and to review their information. Procedure 1 In Inventory, select Hosts and Clusters. 2 Select a host and click the Configuration tab. 3 In Hardware, select Storage Adapters. 4 To view details for a specific adapter, select the adapter from the Storage Adapters list. 5 To list all storage devices the adapter can access, click Devices. 6 To list all paths the adapter uses, click Paths. 10 VMware, Inc.
Copy Storage Adapter Identifiers to the Clipboard If your storage adapters use unique identifiers, such as an iSCSI Name or WWN, you can copy them to a clipboard directly from the vSphere Client. Procedure 1 In Inventory, select Hosts and Clusters. 2 Select a host and click the Configuration tab. 3 In Hardware, select Storage Adapters. 4 Select the adapter from the Storage Adapters list. 5 In the Details panel, select the value in the name field, right-click, and select Copy. Types of Physical Storage The ESXi storage management process starts with storage space that your storage administrator preallocates on different storage systems. ESXi supports the following types of storage: Local Storage Stores virtual machine files on internal or directly connected external storage disks. Networked Storage Stores virtual machine files on external storage disks or arrays attached to your host through a direct connection or through a high-speed network. Local Storage Local storage can be internal hard disks located inside your ESXi host, or it can be external storage systems located outside and connected to the host directly through protocols such as SAS or SATA. Local storage does not require a storage network to communicate with your host. You need a cable connected to the storage unit and, when required, a compatible HBA in your host. The following illustration depicts a virtual machine using local SCSI storage. Figure 1-1. Local Storage VMFS Host virtual machine SCSI Chapter 1 Introduction to Storage In this example of a local storage topology, the host uses a single connection to a storage disk. On that disk, you can create a VMFS datastore, which you use to store virtual machine disk files. VMware, Inc. 11
