Hardware RAID in Linux
There are different levels of hardware RAID available; not all of them are supported options for HP Linux
workstations.
●
Hardware-assisted RAID is a step up from software RAID, but is not considered true hardware
RAID. Hardware-assisted SAS RAID uses the LSI megaraid driver already present in the Linux
kernel. It is provided by the LSI 3041E plug-in card on the HP xw4000 and xw6000 Workstation
series and by the LSI 1064 and 1068 controllers on the motherboard on the HP xw8000 and xw9000
Workstation series.
●
True hardware RAID, also known as raid-on-chip, or ROC, makes use of a dedicated RAID
processor. It is provided by the LSI 8344ELP and 8888ELP plug-in cards on the HP xw8000 and
xw9000 family platforms. SAS drives are the only drives supported for use with RAID on HP Linux
workstations.
●
Hardware-assisted SATA RAID requires use of the dmraid interface, and is not supported on HP
Linux workstations.
Supported Configurations
Hardware RAID for HP Linux workstations is currently supported for user-configured RAID solutions for
the HP workstations below. Not all configurations that are made available by the RAID chipsets or plug-
in cards are supported by HP; only the configurations listed below are supported on HP Linux
workstations.
