This data object type describes the VMware File System (VMFS) creation specification.

Once created, these properties for the most part cannot be changed. There are a few exceptions.

HostScsiDiskPartition
extent
Required

This data object type describes the specification of a Disk partition.

integer As int32 As int32
blockSizeMb
Optional

Deprecated as of vSphere API 6.5, use blockSize instead.

The block size of VMFS in megabytes (MB).

Determines the maximum file size. If this optional property is not set, the maximum file size defaults to the maximum file size for the platform.

In VMFS2, the valid block sizes 1MB, 2MB, 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB. In VMFS3, the valid block sizes are 1MB, 2MB, 4MB, and 8MB. In VMFS5, the only valid block size is 1MB.

integer As int32 As int32
majorVersion
Required

Major version number of VMFS.

This can be changed if the VMFS is upgraded, but this is an irreversible change.

string
volumeName
Required

Volume name of VMFS.

integer As int32 As int32
blockSize
Optional

The block size of VMFS in kilotypes (KB).

Determines the maximum file size. If this optional property is not set, the maximum file size defaults to the maximum file size for the platform.

In VMFS3, the valid block sizes are 1MB, 2MB, 4MB, and 8MB. In VMFS5, the only valid block size is 1MB. In VMFS6, the valid block sizes are 64KB and 1MB.

integer As int32 As int32
unmapGranularity
Optional

The granularity of VMFS unmap operations.

VMFS unmap reclaims unused storage space. The unit is KB. The minimum unmap granularity is 8KB. The maximum unmap granularity is determined by the block size of VMFS blockSize.

string
unmapPriority
Optional

VMFS unmap priority.

VMFS unmap reclaims unused storage space. This determines the processing rate of unmaps. See HostVmfsVolumeUnmapPriorityEnum for supported values.

VmfsUnmapBandwidthSpec
unmapBandwidthSpec
Optional

VMFS unmap reclaims unused storage space.

This data object type describes the specification of VMFS unmap bandwidth.
