Info

vSphere Storage The following table describes the datastore details that you can see when you review datastores. Table 1-3. Datastore Information Datastore Information Description Name Editable name that you assign to the datastore. For information on renaming a datastore, see Device Backing Storage device on which the datastore is deployed (VMFS), or server and folder (NFS). Drive Type Type of underlying storage device, a Solid State Drive (SSD) or a regular non-SSD hard drive. For details, see Chapter 16, “Solid State Disks Enablement,” on page 145. Capacity Total formatted capacity of the datastore. Free Available space. File System Type File system that the datastore uses, either VMFS or NFS. For information about datastores and how to upgrade to VMFS5, see Chapter 17, “Working with Datastores,” on page 153. Storage I/O Control Information on whether cluster-wide storage I/O prioritization is enabled. See the vSphere Resource Management documentation. Hardware Acceleration Information on whether the underlying storage device supports hardware acceleration. The status can be Supported, Not Supported, or Unknown. For details, see Chapter 21, “Storage Hardware Acceleration,” on page 215. Location (VMFS datastores) A path to the datastore in the /vmfs/volumes/ directory. Server (NFS datastores) Name or IP address of a NAS server. Folder (NFS datastores) Name of a mounted folder. Extents (VMFS datastores) Individual extents that the datastore spans and their capacity. System Storage Capability Storage capabilities reported by supported storage devices and inherited by the datastores. You cannot modify them. NOTE A multi-extent datastore assumes the system capability of only one of its extents. Reporting multiple system capabilities for the datastore is not supported. User-defined Storage Capability Storage capabilities that you define and associate with datastores. For information, see “Understanding Storage Capabilities,” on page 242. Path Selection (VMFS datastores) Path selection policy the host uses to access storage. For more information, see Chapter 20, “Understanding Multipathing and Failover,” on page 193. Paths (VMFS datastores) Number of paths used to access storage and their status. Review Datastore Information in the vSphere Client Use the vSphere Client to display all datastores available to the hosts and analyze their properties. Procedure 1 In Inventory, select Hosts and Clusters. 2 Select a host and click the Configuration tab. 3 In Hardware, select Storage. 4 Click the Datastores view. 5 To display details for a particular datastore, select the datastore from the list. 22 VMware, Inc.
Display Datastore Information in the vSphere Web Client Access the Datastores view with the vSphere Web Client navigator. The Datastores view that you display through the navigator lets you list all datastores available in the vSphere infrastructure inventory, analyze the information, and modify properties. You can also use the view to create datastores. To list datastores for a particular parent object, such as a datacenter, cluster, or host, see “List Datastores for an Infrastructure Object,” on page 23. Procedure 1 From the vSphere Web Client Home, click vCenter. 2 Under Inventory Lists, click the Datastores category. Datastores that are available in the inventory appear in the center Datastores panel. 3 Use the icons to create a datastore or to perform basic tasks for a selected datastore. Icon Description Create a datastore. Increase datastore capacity. Mount a datastore to certain hosts. Remove a datastore. Unmount a datastore from certain hosts. 4 To view specific datastore details, double-click a selected datastore. 5 Use tabs to access additional information and modify datastore properties. Tab Description Getting Started View introductory information and access basic actions. Summary View statistics and configuration for the selected datastore. Monitor View alarms, performance data, resource allocation, events, and other status information for the datastore. Manage View and modify datastore properties, alarm definitions, tags, and permissions. Use this tab to access storage devices that back the datastore, and to view and edit multipathing details for the datastore devices. Related Objects View objects related to the datastore. The objects include virtual machines that reside on the datastore and hosts where the datastore is mounted. List Datastores for an Infrastructure Object Display datastores for a specific parent object, such as a datacenter, cluster, or host. Procedure 1 From the vSphere Web Client Home, click vCenter. 2 Use the vSphere Web Client object navigator to browse to an object that is a valid parent object of a datastore, such as a datacenter, cluster, or host. 3 Click the Related Objects tab and click Datastores. If any datastores are configured for this object, they appear in the center Datastores panel. Chapter 1 Introduction to Storage VMware, Inc. 23
