What is the best setup for an zpool intended for database big inserts or TCP/IP dumps (i mean sustained high write throughput using 4 disks ?
I want buy 4 Wd RE4 2TB drives and get the more power i can !
i think of
zpool create tank mirror disk1 disk2 disk3 disk4
zpool create tank mirror disk1 disk2 mirror disk3 disk4
zpool create tank disk1 disk2 disk3 disk4
i think the solution with two mirror in a pool is the best, but not sure.
edit : ok so mirror IS RAID1. It is not possible to make this setup : RAID0 (RAID0, RAID0)
