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

_STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR structure

Description

The STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR structure describes the physical topology of a device or adapter.

Members

Version

Version of this structure, in bytes. The value of this member will change as members are added to the structure. Set to sizeof(STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR).

Size

Total size of the data, in bytes, which may include data that follows this structure. Should be >= sizeof(STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR).

NodeCount

Total number of storage nodes in the system.

Reserved

Reserved for future use. Do not use.

Node

Array of STORAGE_PHYSICAL_NODE_DATA structures that describe the physical device data of each storage node. The number of structures in the array is determined by NodeCount.

Remarks

The STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR structure is returned from an IOCTL_STORAGE_QUERY_PROPERTY request that has a PropertyId of StorageAdapterPhysicalTopologyProperty or StorageDevicePhysicalTopologyProperty.
