Advanced Transport APIsLast Updated December 16, 2024
For managed disk, the first release of VDDK required network access ESXi host (LAN or NBDSSL transport). With VDDK 1.1 programs can access virtual disks directly on a storage device, LAN-free. Direct SAN access increases I/O performance. To select the most efficient transport method, a set of APIs is available, including:
- VixDiskLib_InitEx()– Initializes the advanced transport library. You must specify the library location. ReplacesVixDiskLib_Init()in your application.
- VixDiskLib_ListTransportModes()– Lists transport modes that the virtual disk library supports.
- VixDiskLib_ConnectEx()– Establishes a connection using the best transport mode available, or one you select, to access a given machine’s virtual disk. Currently it does not check validity of transport type. ReplacesVixDiskLib_Connect()in your application.
