3 Hardware Preparation
Hardware preparation tasks are documented in the HP XC Hardware Preparation Guide. This
chapter contains information that was not included in that document at the time of publication.
3.1 FakeRAID Controllers Are Not Supported
The HP XC kernel will not boot on ProLiant DL160 G5 nodes configured with Fake Hardware
RAID.
Hardware RAID setups that are created with the "HP Embedded G5 SATA RAID Controller"
found in some DL160 G5 servers are not supported in HP XC. Those hardware RAID controllers
are not full blown hardware RAID controllers (also called FakeRAID controllers) and are known
to have performance and reliability issues.
Consider using a separate SmartArray or other compatible Hardware RAID card on DL160 G5
servers.
