The hardware-based array manages the RAID subsystem independently from the host. It presents a single disk per RAID array to the host.
A Hardware RAID device connects to the SCSI controller and presents the RAID arrays as a single SCSI drive. An external RAID system moves all RAID handling

(i.e., instances of executing programs). The are differences in the runlevels according to the operating system.
Seven runlevels are supported in the standard Linux kernel (i.e., core of the operating system).
