ZFS and 4gb

#1

Post by tarnis » 22 Jan 2013 15:15

Hi all,

I've read in a few places I can get away with ZFS with only 4GB, I've also seen there's realistically an 8GB minumum but the board maxes out at 4. It will only be myself using the NAS for storing pictures(RAW files). Had some issues with WHS and decided it was time to move on anyways...although I really preferred the Drive Extender methood of things for my uses.

I currently have 4 2TB EADS drives and 2 2TB EAXS drives I received as replacement for dead drives. They're all attached to a SUPERMICRO MBD-X7SPA-H-O motherboard and I have an 8gb sandisk drive in the internal USB port...

Is anyone else using this board? What settings are recomended when I setup the drive pool? Is 4GB really enough for this many drives?

YES if you do not use advanced features like dedupe,etc...

My Brother have only 4GB and 4x2TB disk in RaidZ1, and have 80MBps, but only use SMB shares and no use advanced features ( I need to install ZFSkerntune to tune ZFS to use 4GB), and other tunes in SMB, but after 1 hour, testing diverse config, finally, works very well for home NAS.

PD: I enable bittorrent (transmission), and install minidlna and owncloud, but because my brother only use it sporadic ( very little), He has no throughput problems.
