Dell R510 with 12 disks and PERC H700 raid controller .
The server main used for web server and file backup . and want to install FreeBSD Root on ZFS
I found this .
12x 1TB disks can be done in multiple ways:
12-disk raidz2 vdev (10 TB, can lose any 2 disks, horribly slow, don't do it)
2x 6-disk raidz2 (8 TB, can lose 2 disks in each vdev, faster than above)
3x 4-disk raidz2 (6 TB, can lose 2 disks in each vdev, faster than above)
3x 4-disk raidz1 (9 TB, can lose 1 disk in each vdev, faster than above)
4x 3-disk raidz1 (8 TB, can lose 1 disk in each vdev, faster than above)
6x 2-disk mirror (6 TB, can lose 1 disk in each vdev, fastest)
What about 2x 6-disk raidz1 ?
Another question.
I read this article http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ1
why install bootcode in every disk and how to replace when one disk broken.
If used two groups another group need install boot code ?
