HP ProLiant DL740 Server - Manual (Page 197)

Configuring the Server
Alternatively, an Ultra3 SCSI RAID controller can be installed in any PCI/PCI-X
slot, bypassing the Smart Array 5i Controller. It is also possible to bypass the Smart
Array 5i Controller and install a simple SCSI controller (not an array controller) into
a PCI/PCI-X slot. For detailed instructions on how to bypass the Smart Array 5i
Controller, refer to the “Installing the Integrated Array Bypass” section in Chapter 4.
CAUTION: Back up your data before you move drive arrays or change the
configuration.
Option ROM Configuration for Arrays
After the POST sequence successfully concludes, the server then executes the option
ROMs. An option ROM is the code programmed in the 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.
ORCA 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.
