Each CDB can be a total of 6, 10, 12, or 16 bytes, but later versions of the SCSI standard also allow for variable-length CDBs. The CDB consists of a one byte operation code followed by some command-specific parameters. A typical CDB structure is: bit→ ↓byte 7 6 5 4 3 2 1 0 0 Operation code = 03h 1 LUN Reserved 2 Reserved 3 Reserved 4 Allocation length 5 Control  This computer hardware-related article is a stub.
