Hi All

Which is the better for ZFS storage, nas4free or freenas?
Not sure what other info to supply, so please request for better understanding.

What do you mean by "better"? They both implement ZFS very well, and in part it will probably come down to feature set and personal preference. I do like FreeNAS better, but that's probably because I've used it more.

Did a bit of googling last week and see some people prefer nas4free as its easier to recover in a disaster, but the posts were in 2012. Maybe things have changed since then? any experience with this?
I like freenas as it has a much better webgui. Nas4free is bland..

Another question....with ZFS rule of thumb is to have 1gb of ram per 1tb of storage. Is this the final storage?
eg. 16x2tb(32tb) = 32gb ram... now does this mean that i only need 16gb ram for raid10(16tb)?

Requirements for freenas is that you need a minimum of 8gb of ram....does this include the zfs ram or ontop of the zfs ram?
On the other hand, nas4free needs a minimum of 512mb of ram...

Most recommendations for RAM I've seen are based on zpool size, so in your example, 32gb. Yes, the 8GB RAM recommendation includes the ZFS recommended amount, for up to 8TB of zpool. The OS itself uses about 1GB. NAS4Free recommend 512MB, but that's before considering what file systems you're using. They recommend 4GB+ for ZFS.

As to how much more, well, I personally don't see the *need* to match 1GB RAM:1TB zpool, unless you're using features like deduplication or AD integration, though it can help keep performance high. If you're doing 16x2TB disks in RAIDZ10, I would want at least 16GB RAM. If budget allows, 32GB. If you want to dedupe, at least 64GB (and ideally 160GB). ZFS is incredibly RAM-intensive, and while I've not seen FreeNAS have any stability issues with 8GB of RAM (even in an implementation with 12x3TB disks), performance will slump if you don't have enough for your setup. The issue I had with NAS4Free, on the other hand, was stability (same hardware, 8GB RAM, 12x3TB disks).

So, in short, either one you should aim for 1GB:1TB ratio, but you can get away with less as long as it's >8GB and >= 512MB:1TB zpool if you're not as fussed about speed. NAS4free with 512MB RAM trying to handle 16x2TB drives is just asking for it to fall over in a pile in my experience, sorry.

As to disaster recovery, I've not had a recovery situation where FreeNAS was an issue, though aside from HDD failures, I've only had to deal with one controller failure on a freenas box, and we just swapped it for one identical and was all good. At the end of the day, ZFS is not a backup replacement ;)

Thanks! very detailed response which has clarified a lot of things.
You dont perhaps have 32GB (4x8gb) ram chips laying around? :)

When you say controller...you not referring to raid controller are you?

Xpenology FTW
Think Synology DSM software, but for pretty much any x86 hardware.
It's awesome

Just a SAS PCIe card.

I've been meaning to try that out, I quite like DSM on the rackstations, so might have a go with this... I have another Proliant microserver to have a play with soon, so maybe will try it there if it's suitable ;)

I've been running xpenology for 6 months now on an ibm x3100 without any issues with 2x 4tb disks and 2x 2tb disks
using it for cifs/smb storage as well as plex and nfs storage for 2 esxi hosts
