Datastore Detail

Detail reports are related to a specific enterprise object, such as a backup job. You can only access detail reports through a link presented in the context of a main report, providing additional information that augments the main report. Detail reports cannot be generated, customized, or saved, as they are specific to the report from which they were derived. They are not available in search results.

Explore your data center using IT Analytics customizable report templates or by using parts of your IT infrastructure as entry points. Use Search to find reports, templates and dashboards across the portal.

Use the Reports tab to examine the IT Analytics catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. The main report is located here:

Virtualization Manager > Storage Capacity & Utilization > Datastore Utilization

Click a Datastore name.

Table: Datastore Detail

Column name

Description

Name

Name of the datastore.

Cluster Name

The name of the cluster to which the datastore belongs.

Type

Datastore type: a specific NFS file system or NAS.

Server

This field is related to Datastore type and will be populated only when the type is NAS.

Folder

The VM folder in which this Datastore is located. This field is related to Datastore type and will be populated only when the type is NAS.

Multiple Host Access

Indicates if this datastore can be shared by multiple hosts: Yes or No.

Last Updated

Timestamp of the last write access.

VMDK Max File Size

The capacity of a virtual disk from the point of view of a virtual machine.

# VMs

This number links to the VM Summary report, listing the VMs associated with this Datastore.

# Extents

The number of extents that were added to expand the datastore (up to 32 physical storage extents).

# Disks

The number of physical disks associated with the datastore.

# Arrays

The number of arrays from which this datastore gets physical storage links to Array Capacity & Utilization.

VMDK Used

The sum of all virtual disks - VMDK (.vmdk files). This sum does not include snapshot metadata files, however, other outdated snapshot data may be in vmdk files. For this reason, VMDK Used may exceed VM Disk Capacity, the amount that was configured when the VM was created.

Total VM Used

Size of the virtual machine, which includes VMDK files, log files, and snapshots; the sum of all the files taking up storage by this VM. This value links to the VM Files Summary report, which lists the usage details. For details about data collection options that impact these values refer to the following report.

See Data Collection Options and Datastore Utilization.

Is Thin

Indicates whether or not the datastore supports thin provisioning on a per file basis. When thin provisioning is used, backing storage is lazily allocated.

This is supported by VMFS3. VMFS2 always allocates storage eagerly. Thus, this value is false for VMFS2. Most NAS systems always use thin provisioning. They do not support configuring this on a per file basis, so for NAS systems this value is also false.

Total Capacity

Total capacity of this Datastore.

Free Capacity

Available capacity in this Datastore

Used Capacity

Amount of this Datastore's capacity already in use

Capacity Usage

Mouse over this thermometer to view the usage percentage

VMDK Allocated

This is the current allocated size of all VMDKs in the datastore.

VM Not In Inventory

Indicates VMs that are not currently in the inventory, but are taking up space in the Datastore. These are VMs that are not visible in VMware vCenter. Click this link to view the VM Files Summary. This value will be zero if data collection is configured to collect data from only datastores associated with VMs in the inventory. For details about data collection options that impact these values, refer to the following report.

See Data Collection Options and Datastore Utilization.

Over Provisioned

Indicates what percentage is over-provisioned. This helps you in evaluating possible virtual environment expansions.
