I ran FreeBSD with ZFS for a while on a whitebox ESXi (5.1) server at home
using raw device mappings to local SATA drives. ESX doesn't support
RDM directly for non-SAN type storage but it can be done. Here's the
page I used to get it working:
Obviously this does need some degree of caution - it worked just fine
for me at home but I don't think I'd stake my job on this setup :-).
Also although ZFS seemed perfectly happy with the pass-through RDM
devices, you aren't getting 100% raw access to the drives (eg SMART
monitoring didn't work).
