VDS_HBAPORT_SPEED_FLAG enumeration (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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

typedef enum _VDS_HBAPORT_SPEED_FLAG {
  VDS_HSF_UNKNOWN = 0,
  VDS_HSF_1GBIT = 0x1,
  VDS_HSF_2GBIT = 0x2,
  VDS_HSF_10GBIT = 0x4,
  VDS_HSF_4GBIT = 0x8,
  VDS_HSF_NOT_NEGOTIATED
} VDS_HBAPORT_SPEED_FLAG;

Constants

 
VDS_HSF_UNKNOWN
Value: 0
The HBA port speed is unknown. The transceiver is incapable of reporting.


HBA_PORTSPEED_UNKNOWN
VDS_HSF_1GBIT
Value: 0x1
The HBA port supports a transfer rate of 1 gigabit per second.


HBA_PORTSPEED_1GBIT
VDS_HSF_2GBIT
Value: 0x2
The HBA port supports a transfer rate of 2 gigabits per second.


HBA_PORTSPEED_2GBIT
VDS_HSF_10GBIT
Value: 0x4
The HBA port supports a transfer rate of 10 gigabits per second.


HBA_PORTSPEED_10GBIT
VDS_HSF_4GBIT
Value: 0x8
The HBA port supports a transfer rate of 4 gigabits per second.


HBA_PORTSPEED_4GBIT
VDS_HSF_NOT_NEGOTIATED
The HBA port speed has not been established.


HBA_PORTSPEED_NOT_NEGOTIATED

Remarks

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