NAME
     draid - system driver for the two channels of a RAID box

DESCRIPTION
     draid is a driver in the operating system kernel and is located
     between the general I/O systems and the physical RAID driver.

     The draid driver is connected to the general I/O systems over a device
     node, and uses two or more physical RAID device nodes. The draid
     driver transmits the I/O systems' requirements to a physical RAID
     device node. If one of the device nodes fails for any reason, the
     draid driver transmits all subsequent I/O requirements over an alter-
     native physical RAID device node which is still available. The tasks
     intended for the failed device node are repeated over the device node
     that is still available.
