Hi Reco,
How many client connections?
I don't think you'll find anyone in the world that will come close to that amount of storage solely managed/attached to OSX, mainly because HFS is one of the
worst FileSystems still used today. At least I don't have to tell you about that given you're in this forum
I like OSX, but I wouldn't trust it with that much data attached, even with ZFS.
I have OSX 10.10.3 Server 24GB RAM at home with ZFS (1.3.1-r2 with arc limited to 16GB) and 6 x 4TB drives mirrored connected via a
RR2744 SAS HBAEvery 90 days or so I need to reboot the server because the network stack is completely unpingable...
I use Apple's SMB exclusively now. (I used to use NFS) you sure you can't omit AFP from your environment?
ServerSideCopy isn't implemented yet, but it sure will be nice once it is...
When Mac customers want/need more storage > 50TB, I tend to deploy boxes from
GBLabs to keep the support simple.
Admittedly, the customers I deal with needing this much storage are mostly media based – i.e. they have bugger all understanding about enterprise storage and so simple = best here.
In my man-cave, I have an old/ancient system that I play with for ZFS.
1 x 2009 Xserve 32GB RAM (1.3.1-r2 with arc limited to 16GB)
1 x Brocade 300e FC switch
5 x Xserve xRaids (only three are full of disks and connected to the FC switch)
So that's 42 disks connected (as JBOD) to the Xserve for ZFS to manage.
I use ZFS's snd/rcv to move data from the pool of 4TB disks to this old clunker using cheap nasty Chelsio 10GBe cards (point to point)
After transferring ~ 8TB to the Xserve, I'm unable to export the pool...
I thought it was flushing caches/ARC but I've left it for a good few hours and the pool is unresponsive.
Issuing a reboot hangs too because of ZFS doing "something" so I resort to hard rebooting the Xserve and then all is fine after that.
Massive PITA to diagnose because I don't want to have to move 8TB over the network again just to repeat the conditions to diagnose...
So like I said... I wouldn't trust OSX with that much storage... not yet anyway.
