Figure 3 Reliability: RAID 1 - Mirroring Configurations Recommended configurations HP recommends factory configurations of the preinstalled RAID offerings for the HP Compaq dc5750 Business PCs. The preinstalled RAID offering is a RAID 1 volume of two identical SATA hard drives, and either two SATA 80GB/8MB cache, two SATA 160GB/8MB cache, or two SATA 250GB/8MB cache drives. NOTE: When the HP Compaq dc5750 Business PC products launch, the only supported operating system is Microsoft Windows XP Professional Service Pack 2 (SP2). RAID Configurations are only supported with this operating system. Hardware support is present to take advantage of the future Microsoft Vista operating system. HP Compaq dc5750 Business PCs are based on the ATI Radeon Xpress 1150 chipset, which is a combined hardware and software RAID solution. The Radeon mass storage controller allows all drives to operate in IDE or RAID SATA modes. Each mode of the controller means a different PCI controller, with different device ID, class code, and driver support. NOTE: HP recommends and only supports Microsoft's IDE driver stack based on ATAPI.SYS and ATI drivers for HP Compaq Business PC products, including all supported RAID configurations. 7

Reliability: RAID 1 - Mirroring

Configurations

Recommended configurations

HP recommends factory configurations of the preinstalled RAID offerings for the HP Compaq dc5750

Business PCs.

The preinstalled RAID offering is a RAID 1 volume of two identical SATA hard drives, and either two SATA

80GB/8MB cache, two SATA 160GB/8MB cache, or two SATA 250GB/8MB cache drives.

NOTE

: When the HP Compaq dc5750 Business PC products launch, the only supported operating system

is Microsoft Windows XP Professional Service Pack 2 (SP2). RAID Configurations are only supported with

this operating system.

Hardware support is present to take advantage of the future Microsoft Vista operat-

ing system.

HP Compaq dc5750 Business PCs are based on the ATI Radeon Xpress 1150 chipset, which is a com-

bined hardware and software RAID solution. The Radeon mass storage controller allows all drives to oper-

ate in IDE or RAID SATA modes. Each mode of the controller means a different PCI controller, with

different device ID, class code, and driver support.

NOTE

: HP recommends and only supports Microsoft’s IDE driver stack based on ATAPI.SYS and ATI driv-

ers for HP Compaq Business PC products, including all supported RAID configurations.
