Redundant Array of Independent Disks (RAID) on HP Compaq dc5750 Business PCs Using ATI Array Management Software (WebPAM) Introduction ............2 Mirroring and Parity . -
Page 2: Introduction
RAID technology takes advantage of Serial Advanced Technology Attachment (SATA) and the integration of RAID into ATI’s Radeon Xpress 1 150 chipset with SB600 technology. The HP Compaq dc5750 Business PC products incorporate RAID drive support through factory configurations. This white paper provides a basic overview of RAID technology, supported factory configurations of HP Compaq dc5750 Business PCs, and other supported RAID configurations. - Page 3 Group of all strips going horizontally across all the hard drive members of a RAID 0 volume. Table 2 RAID Drives Mode Purpose Minimal HDD Required RAID 0 Striped for Performance. RAID 1 Mirrored for Protection. RAID 0 + 1 Mirrored and Striped. * Not supported on HP Compaq dc5750 Business PCs.

Page 4: Basic Raid Types
NOTE: The following notes are important for RAID configuration: • RAID 1 is the only RAID configuration that HP Compaq dc5750 Business PC products offer as factory configurations. • The preconfigured systems: - Are complete RAID systems. - Have both drives installed. - Page 5 Figure 1 Performance - RAID 0 with two hard drives The HP Compaq dc5750 Microtower also allows for RAID 0 with three hard drives. However, reliability is less than a RAID 0 configuration with two hard drives. RAID 0 with three hard drives is shown in the following figure:...

Page 6: Raid 1 With Two Hard Drives (Mirror)
Because it is 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 dc5750 Business PCs. RAID 1 provides high availability with minimal performance impact, as well as greater reliability compared to a single hard drive configuration. -
Page 7: Configurations
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 1 150 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. -
Page 8: Hp Backup And Recovery Interactions
WARNING: The PCI Device ID of the mass storage controller changes after changing the BIOS “SATA Emulation” Computer Setup option. Changing SATA Emulation from IDE mode to RAID mode is the equiv- alent of connecting the hard drives to a new add-on RAID storage controller. The installed operating sys- tem on the hard drive is unaware of this new mass storage controller. -

Maximum of one SATA optical drive. Unsupported configurations The HP Compaq dc5750 Business Desktop PC products only support the best user experience and highest possible reliability. As a result, HP does not support the following combinations of RAID hard drives: •... -
Page 10: Configuring Raid On Non-Factory Preinstalled Configurations
Configuring RAID on non-factory preinstalled configurations The remaining sections of this white paper describe steps to set up supported RAID configurations where customers have not purchased factory preinstalled RAID configurations. WARNING: Before configuring RAID, be sure to back up all data. Once a RAID configuration is executed and saved, data on the selected disks is no longer retrievable. -

The screen below displays briefly during boot up. The RAID configuration utility is English only. To configure RAID in other languages, use the Web-based RAID configuration utility. For more information refer to the comprehensive WebPAM User Manual. Configuring RAID Volume using the Option ROM Once you are in the Option ROM you can access the FastBuild Utility Main Menu. - Page 13 From the Main Menu press 3 to access the Delete LD screen. Use the arrow keys to select the drives. Press Del or Alt + D to delete the drives. At the prompt, press Ctrl + Y to delete or any other key to abort.
- Page 14 Press 2 to access the Define LD screen. This screen allows you to configure RAID settings and assign- ments. Use the arrow keys to scroll to the desired LD number and press Enter.

Page 15: Select Boot Order
Select boot order Only the first optical drive is bootable in RAID mode. To set up your system to boot from the CD, you will need to change the boot order. Turn on or restart the computer by clicking Start > Shut Down > Restart the Computer. Press F10 as soon as the monitor light turns green. - Page 16 Press S at the prompt to Specify Additional Device. Insert the RAID driver floppy and press ENTER to select the RAID driver. Press ENTER to complete the Microsoft Windows installation. WARNING: Customer-created images MUST account for the RAID controller. Failure to install and enumerate the RAID driver after enabling the RAID controller (with or without creat- ing a volume) will result in a Windows boot failure (blue screen) for inaccessible boot device.
