NAS setup recommendations

since I am about to setup a NAS box for private and business usage (it
will also be providing additional services), I would like to ask for
recommendations on what I might use. Maybe somebody already had similar
intentions and realized that setup.
The hardware is already in place and it basically contains HW proposed
here (except for the HDD configuration and wih an additional 480G SSD
Ideally I would like to setup a RAID1 with a small boot partition and
encrypting the rest just like it is demonstrated in encrypted_root.sh in
the /usr/share/examples/rcconfig dir of a DragonFly installation.
My high level requirements are:
1. encrypt as much as possible i.e., also / if possible
2. implement resilience to minimize down times
3. using hammer as the predominant file system to allow for fine grained
In order to also support RAID1 I tried to set up vinum before encrypting
the vinum volume with dm. But this has not worked out, maybe I did
something wrong in configuring the loader variables for initrd. I read
that it was planned to add mirror support in dm, but it has not been
implemented so far. Maybe the reason is that with hammer there is
already a descent mirror solution available. Although I think hammer
mirror does not suit me 100% because of the expected down time in case
of the master drive failing i.e., on would have to convert slave pfs to
master pfs or cpdup the slave pfs contents to newly setup master pfs.
Is there a configuration I might use to realize my three requirements above?
Would using LVM be a viable alternative?
