6Tb Database with ZFS
...he better but i cant set too much memory. Have someone implemented succesfully something similar? We ran some test and the usage of memory was as follow: (With Arc_max at 30Gb) Kernel = 18Gb ZFS DATA = 55Gb Anon = 90Gb Page Cache = 10Gb Free = 25Gb My system have 192Gb RAM and the database SGA = 85Gb.
