Recent array controllers can do this (logical drives distributed across 
one or more arrays of physical devices), though the HP/HPE 
documentation here seemed lacking.

Among these, P410 and P812, and others.

You'll probably be using MSA$UTIL to establish this, and/or one of the 
HP/HPE tools.

Getting disks in and out of the RAIDset can sometimes be a little 
tricky to manage when a failure arises. Best to get extra HDDs or SSDs, 
and pre- provision some into the arrays as spares.
