Hi,
I've recently upgraded my old DIY NAS to enterprise hardware from Supermicro and now the time has come for my old disks to get replaced.
Currently there are 4 x WD Red 6TB and 4 x WD Red 3TB disks in my ZFS RAIDZ1+0 configuration, giving me access to 50% of available storage. Amount of available RAM on server is 128GB. See images below.
1.0 Disks
1.1 ZFS pool
These drives are to be replaced by 8 x Seagate Exos 16TB drives (will add 4 more disks later on) and I am looking into what configuration would be most optimal for me, my requirements are speed and realibility - money is not a issue and I can live with 50% available storage (I've been doing it so far ;)). As far as I've understood RAID-Z2 is the new kid on the block since all those years back I've put together my ZFS pool and it seems to be the recommended configuration. Am I right and what sort of performance difference am I looking at when compared to current setup if switching to RAID-Z2?
Also, any recommendations how I would go about upgrading or replacing the old pool? There are 12 hot swap bays in the Supermicro case, 8 of those are taken up by WD Red disks to be replaced.
