## Data Object Description

Backing options for virtual disks that use the space efficient sparse format.

Space for Flex-SE disks is allocated on demand and optimizations are applied to achieve additional space savings.

Properties

Name | Type | Description
--- | --- | ---
deltaDiskFormatsSupported | VirtualDiskDeltaDiskFormatsSupported[] | Delta disk formats supported for each datastore type.
diskMode | ChoiceOption | The disk mode. Valid disk modes are: persistent independent_persistent independent_nonpersistent See VirtualDiskMode
growable | xsd:boolean | Indicates whether or not this disk backing can be extended to larger sizes through a reconfigure operation. If set to true, reconfiguring this virtual disk with a capacityInKB value greater than its current value will grow the disk to the newly specified size.
hotGrowable | xsd:boolean | Indicates whether or not this disk backing can be extended to larger sizes through a reconfigure operation while the virtual machine is powered on. If set to true, reconfiguring this virtual disk with a capacityInKB value greater than its current value will grow the disk to the newly specified size while the virtual machine is powered on.
uuid | xsd:boolean | Flag to indicate whether this backing supports disk UUID property.
writeThrough | BoolOption | Flag to indicate whether or not the host supports allowing the client to select "writethrough" as a mode for virtual disks. Typically, this is available only for VMware Server Linux hosts.
