CONFIGURING the SERVER
Notes . . .
1. 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.
2. 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.
3. Dual RAID controllers are not supported in this server
4. External RAID card is the 9285CV-8e or 9286CV-8e. Any of these cards can be installed simultaneously with one
mezzanine RAID controller card. It cannot be used simultaneously with an internal RAID controller card
(9271-8i or 9271CV-8i) because of mounting space limitations for the supercap (there is space to mount only
one supercap).
5. A = available slot, O = occupied slot, U = unsupported slot (slot 2 is not supported in 1-CPU systems)
6. The mezzanine slot is not supported in 1-CPU systems
Caveats
Note that only a single Cisco VIC card (the half-height Cisco VIC 1225 or 1285 PCIe card) is
■
supported and it must be installed in the full-height PCIe slot (slot 1) on riser 1. So take this
into account when populating RAID controller cards.
You can choose an optional RAID configuration (RAID 0, 1, 5, 6, or 10), which is
■
preconfigured at the factory. The RAID level you choose must be an available RAID choice for
the controller selected. RAID levels 50 and 60 are supported, although they are not available
as configuration options.

NOTE: RAID for the external RAID controllers (LSI MegaRAID SAS 9286CV-e and LSI
MegaRAID SAS 9285CV-e) is not factory configured.
