StorNVMe command set support
The tables in this article list:
- Commands and opcodes defined in the NVM Express specifications for the NVMe Admin Command Set.
- All I/O Commands (Base Specification), I/O Commands for the NVM Command Set, and I/O Commands for the Zoned Namespace Command Set.
The tables include the following information:
- Header Definition – Indicates that an enumeration for the command is defined in the relevant Windows header file.
- StorNVMe Supported – Indicates that the StorNVMe device driver supports the command on Windows 10 version 1903 and later.
- Driver Int Use (Driver Internal Use) – Indicates that the StorNVMe driver can internally generate/issue the command.
- Comments – Any other relevant information; for example, whether the command can be issued as part of an IOCTL operation. "WinPE Only" indicates that the command is supported only on WinPE editions of Windows.
