[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Defines the set of valid types for a LUN plex.

Constants

 
VDS_LPT_UNKNOWN
Value: 0
This value is reserved.
VDS_LPT_SIMPLE
The plex type is simple—it is composed of extents from exactly one drive.
VDS_LPT_SPAN
The plex type is spanned—it is composed of extents from more than one drive.
VDS_LPT_STRIPE
The plex type is striped, which is equivalent to RAID 0.
VDS_LPT_PARITY
The plex type is striped with parity, which accounts for RAID levels 3, 4, 5, and 6.
VDS_LPT_RAID2
The plex type is RAID level 2.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID3
The plex type is RAID level 3.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID4
The plex type is RAID level 4.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID5
The plex type is RAID level 5.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID6
The plex type is RAID level 6.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID03
The plex type is RAID level 0+3.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID05
The plex type is RAID level 0+5.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID10
The plex type is RAID level 1+0.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID15
The plex type is RAID level 1+5.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID30
The plex type is RAID level 3+0.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID50
The plex type is RAID level 5+0.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID53
The plex type is RAID level 5+3.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.
VDS_LPT_RAID60
The plex type is RAID level 6+0.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.

Remarks

The VDS_LUN_PLEX_PROP structure includes a VDS_LUN_PLEX_TYPE value as a member to indicate the existing plex type.

If your application encounters a VDS_HWPROVIDER_TYPE value that it does not recognize, it should display the provider type as unknown. It should not attempt to map the unrecognized provider type to another provider type.

Note  Additional constants might be added to the VDS_LUN_PLEX_TYPE enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_LUN_PLEX_TYPE enumeration constant.
