I'm going to be setting up a new server to run several Xen
machines. I
plan to have two drives and use (software) RAID for
reliability. I'm
curious how other people are doing this.
One apparent option, for the production DOMUs, is to have
matching
partitions on each hard drive, and have the DOMUs do RAID
themselves. A
second is to use a large DOM0 partition, with RAID, and
assign a DOMu a
file in that partition. This strikes me as slower, but
adequate for
light-load and experimental servers.
Of course, the real question is whether either or both
options actually
work.
