VDS_HBAPORT_SPEED_FLAG enumeration (vdshwprv.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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 flags for determining the speeds supported by an HBA port. These values are used in the ulPortSpeed member of the VDS_HBAPORT_PROP structure.

Syntax

  VDS_HSF_2GBIT,
  VDS_HSF_10GBIT,
  VDS_HSF_4GBIT,
  VDS_HSF_NOT_NEGOTIATED
