I'm having difficulty finding recent information and this forum looks like the best place to ask, so if anyone has any information that would be great. I'll try to keep it simple. My intention is to create a ZFS storage node that I can share with other physical machines and vm workstations. Cheaper is always better, available hardware is: Xeon W3690 24GB ECC HP Motherboard from z400 (don't have the # handy). 3ware 9650se 24m8 1. Is FreeBSD10 the only ZFS OS option that supports full drive encryption? 2. Is OpenSolaris the best performing ZFS OS option? 3. Is OmniOS the best ZFS OS option for ongoing support? 4. With depuplication and all the other treats running, how much hard drive space will I be able to run with 24GB RAM? Does it vary at all from FreeBSD to OmniOS or other illumos'? 5. Does FreeNAS still lack features when compared with the other options? I've seen lots of old posts about moving on to better systems but they still seem to be one of the better supported options, even if the scope is more limited. The only comparisons I can find are years out of date. I'm intending to mess about with virtualisation on some other machines and so I'm not entirely sure what I will want from this storage machine just yet. Sorry if I've missed a thread that explained just this but I'm finding it hard to information at a high level that is newer that 2013. I'm happy to go with opensolaris or freebsd10 or openindiana but if the newer options are more suited to me then I'd like to take advantage of that.
