Sure. That either wasn't available or was not within what I was willing to spend in \
2016 when I set up this system.

Software RAID is not possible with VMware ESXi, which is what we are using and which \
is where the storage needs to be addressable from*.

*with the exception of the hard disk RAID that holds the master copy of the rsync \
server, including packages and distfiles, which is the built-in hardware RAID of one \
of the Xserves which VMware ESXi itself cannot use but which is mapped directly into \
the single VM that needs to use it.
