Compaq dc7800 - Convertible Minitower PC User Manual

13
NOTES: The following notes are important for RAID configuration:
• RAID 1 is the only RAID configuration that HP Compaq dc7800 Business PC products offer
as factory configurations.
• The preconfigured systems:
- Are complete RAID systems.
- Have both drives installed.
- Have the necessary Option ROM configuration.
- Are preloaded and preinstalled with all required Intel software.
- Include a preinstalled operating system that is mirrored mode out of the box.
HP Backup and Recovery interactions
After enabling and configuring RAID, restore the system using backup CDs. After completing the restore,
reinstall HP Backup and Recovery. These steps are necessary for the F11 restore to function properly.
HP also recommends keeping the default options in the RAID Option ROM and in the Windows RAID
application. Options like “chunk” size for changing the size “stripe” size have more history in their
defaults settings.
Additional technical information will be provided in the future for customers who want to add RAID soft-
ware image deployment capabilities.

• Two hard drive configuration.
