Caveats
■ If you select an internal drive RAID controller, it is installed by default in PCIe slot 4
(half-height) or 3 (full-height); however, you can go into the BIOS and change the option

Notes . . .
1. Embedded RAID is only compatible with the 16 HDD backplane. It cannot be used with the 24 HDD backplane.
2. Never disable OPROM for the mezzanine slot if the mezzanine card is present, or the system will not boot. If you
remove the mezzanine card and disable its OPROM, you can boot from another bootable device (RAID card,
embedded RAID, or from SAN via an HBA or CNA card). When you boot from a device, make sure its OPROM is
enabled, it is in the proper boot sequence, and its BIOS is configured for a bootable device.
3. If you want to boot from a device other than the 9271-8i or 9271CV-8i MegaRAID PCIe card, you can leave the
card installed. Just disable the OPROM for its slot, and the system will boot even with the card installed.
4. External RAID card is the 9285CV-8e or 9286CV-8e. Any of these can be installed simultaneously with either one
mezzanine RAID controller card or one internal RAID controller card (9271-8i or 9271CV-8i).
5. A = available slot, O = occupied slot, U = unsupported slot (slots 4 and 5 are not supported in 1-CPU systems)
6. The mezzanine cards are not supported in 1-CPU systems
7. The OPROM is enabled for the default PCIe RAID controller slots. If you want to enable a different slot, you must
go into the BIOS and enable the OPROM for the desired slot and disable the OPROM for the default PCIe slot (see
Figure 9 on page 74).
8. The mezzanine cards are not supported in 1-CPU systems
9. Two RAID cards are required to control all 16 drives in the C240 SFF 16 HDD backplane system.
