vmdk 类型

VMware-name	plat- form	files	max size	desc- riptor as text- file	type see *	extensions
monolithicSparse	WS	1	950Gb or 2 Tb	no	0	*.vmdk	This is a growing disk in one piece - the only disk type that uses no external descriptor but an embedded one
monolithicFlat	WS	2	950Gb or  2Tb	yes	2	*.vmdk +  *-flat.vmdk	This is a pre-allocated disk in one piece
twoGbMaxExtentSparse	WS	1 + x	2Gb slices	yes	1	*.vmdk + *-s00*.vmdk	This is a growing disk split into 2Gb chunks
twoGbMaxExtentFlat	WS	1 + x	2Gb slices	yes	3	*.vmdk +  *-f00*.vmdk	This is a preallocated disk split into 2Gb chunks
vmfs	ESX WS	2	depends on  block size  of VMFS  on ESX 256 = 1 Mb 512 = 2 Mb 1024 = 4 Mb 2048 = 8 Mb on  Workstation upto 2 Tb	yes	4 / 6	*.vmdk +  *-flat.vmdk	This is a variant of the "monolithicFlat" format. The max size depends on the block size used to format the VMFS-filesystem. This type can appear as thin provisioned or thick provisioned. For this discussion this subtypes make no difference. Thin provision is a feature of VMFS - not of this disktype itself. Don't mix thin provisioned VMFS-type with monolithicSparse
custom	WS	2		yes		*.vmdk +  third-part-image	Used to mount v2i-and other third party formats
streamOptimized		1		no		*.vmdk	Used with ovf-xml files actually this is a variant of the monolithiocSparse format
