18 .Nd generic block device driver
22 driver supports generic block-oriented devices, such as non-volatile
23 memory storage devices.
24 It provides a hardware independent layer for such storage devices, allowing them
25 to concentrate on the hardware-specific details, while
27 takes care of all the other details, such as
32 driver only supports block-oriented, random-access devices.
33 It does not support traditional rotational media and does not support
36 The most typical use case for
38 devices is to be used to host a file system, such as

58 A controller number, typically one for each instance of
59 each underlying hardware dependent device driver (there can be multiple
60 such drivers in the system.) Controller numbers are dynamically assigned
63 Generally, each instance of the underlying hardware will have a
64 logical unit number as well.
