Option Rom Configuration For Arrays - HP DL760 - ProLiant - 1 GB RAM User Manual

Option ROM Configuration for Arrays

After the POST sequence successfully concludes, the server executes the option
ROMs. An option ROM is the code programmed in the read-only memory (ROM) of
any PCI expansion boards or embedded devices that are installed in the server.
Option ROMs allow you to make hardware configuration changes for each PCI
expansion board. These settings are retained when the server is powered down so that
they can be restored the next time the server is powered up.
The ORCA utility is a hardware-level configuration program that is embedded in the
option ROM of the controller. ORCA is also embedded into the ROM of other array
controllers.
ORCA provides the following benefits:
•
Because it is loaded from ROM, it does not require diskettes or CDs to run.
•
It can be started on initial power-up.
•
It can configure any number of drives.
•
It can be executed during any boot sequence.
•
It allows easy configuration of the following:
— RAID 0, RAID 1, RAID 1+0, and RAID 5 configurations
— Online spare (hot spare)
— Boot controller order
•
It allows independent configuration control over each logical drive.
