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 plugin cards are supported by HP; only the configurations listed below are supported on HP Linux workstations. xw4400 LSI 3041E RAID 0 2-4 drives RAID 1 2 drives xw6400 2-3 drives 2 drives xw8400 xw9400 xw4600 xw6600 xw8600 2-4 drives 2 drives 2-3 drives 2 drives 2 Installing and Configuring SAS Hardware RAID on HP Workstations ENWW
