Members
Version
Contains the size of this structure, in bytes. The value of this member will change as members are added to
the structure. Set to
sizeof(STORAGE_DEVICE_RESILIENCY_DESCRIPTOR)
.
Size
Specifies the total size of the data returned, in bytes. This may include data that follows this structure.
NameOffset
Byte offset to the null-terminated ASCII string containing the resiliency properties Name. For devices with no Name property, this will be zero.
NumberOfLogicalCopies
Number of logical copies of data that are available.
NumberOfPhysicalCopies
Number of complete copies of data that are stored.
PhysicalDiskRedundancy
Number of disks that can fail without leading to data loss.
NumberOfColumns
Number of columns in the storage device.
Interleave
Size of a stripe unit of the storage device, in bytes. This is also referred to as the stripe width or interleave of the storage device.
