Hi I am currently running a ZFS home server and want to add more disks. However my motherboard only has 4 SATA ports which are all used as follows:
Onboard SATA1 : Boot disk Onboard SATA2 : ZFS Disk 1 Onboard SATA3 : ZFS Disk 2 Onboard SATA4 : ZFS Disk 3 I wish to purchase a 4 port SATA PCI controller card (StarTech.com 4 Port PCI SATA uses the Silicom Image SIL3114 Chipset) to accommodate an extra disk in the following configuration: Onboard SATA1 : Boot disk Onboard SATA2 : ZFS Disk 1 Onboard SATA3 : ZFS Disk 2 PCI SATA1 : ZFS Disk 3 PCI SATA2 : ZFS Disk 4 I obviously have to blow my existing zpool, but my question is will I see any performance loss by splitting my disks across different controllers? Or is it better to stick all the 4 disks on the PCI card? Thanks in advance.
