Hardware-RAID NAS System Drive Configuration

A NAS system with hardware RAID configuration contains four SATA hard drives that are connected to a CERC SATA RAID controller. Unlike the software-RAID NAS system where Windows Storage Server 2003 controls the hard drives, the drives in the hardware-RAID NAS system are controlled by a RAID controller card installed in a PCI expansion slot. All four CERC-SATA hard drives appear as only two virtual disks to the operating system. See Table 3-3 and Figure 3-2. The operating system and boot sectors are installed on one RAID 5 volume that is spanned across the four CERC-SATA hard drives. Data can be stored on the other RAID 5 volume that is also spanned across the four CERC-SATA hard drives.

NOTE: RAID 1 hard-drive configurations are not supported on hardware-RAID NAS systems.
