Cannot configure RAID o HP ProLiant DL 385 P400 RAID Controller

[Wade Neuwirth]

I am attempting to build a new machine with 6 disks. When I use ACU or ORCA I do not have the option to choose RAID 1. I want to make the 2 x 72G drives RAID 1 to house the OS (Linux) and the remaining 4 drives RAID 1+0 for data. The only options when creating these arrays (for both) is RAID 0, 1+0, 5 or 6.

Any ideas would be extremely appreciated.

Regards,
Wade

RAID 1+0 is equal to RAID 1.

LOGIC:: when you put 4 drives in RAID 1+0 the data will be striped across 2 drives and will be written to other 2 drives as mirror, but in case of 2 Drives, data is not striped and is written as it is, then will be written to other disk as mirror.

RAID 1+0 is equal to RAID 1 for 2 drive configuration.

THANK YOU. This is what I have been telling everyone. Sometimes you just need the confirmation from outside source.
