Windows Driver Kit DDI reference (ns-ntddstor-_storage_device_resiliency_descriptor)

_STORAGE_DEVICE_RESILIENCY_DESCRIPTOR structure

Description

Reserved for system use.

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.
