out of the box. Basic RAID Types This section provides a brief explanation of the supported RAID configurations for HP Compaq dc7700 and dx7300 Business PCs. RAID 0 with two hard drives (Striped) Even though HP supports RAID 0, it is not the recommended configuration for business PC users. Lack of - HP dc72 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and dx - Page 6
two hard drives At a higher reliability cost with faster performance, HP Compaq dc7700 Business PC Convertible Minitower and dx7300 Microtower also allow for RAID 0 with three hard drives. RAID 0 with two or three hard drives is a supported configuration. RAID 0 with three hard drives is shown in - HP dc72 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and dx - Page 7
a very cost-effective way to increase system storage reliability and a great value proposition, RAID 1 is the only RAID configuration that HP preconfigures for HP Compaq dc7700 and dx7300 Business PCs. RAID 1 provides high availability with minimal performance impact, as well as greater reliability - HP dc72 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and dx - Page 8
Figure 3 Reliability: RAID 1 - Mirroring RAID 5 with three hard drives RAID 5 has been used in servers for many years and is one of the most common types of RAID. RAID 5 uses striping with parity data in distributed blocks across all member disks. Therefore, the mass storage controller can - HP dc72 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and dx - Page 9
