I've had this setup for about a year now and want to restructure my zpool to optimize throughput.
On my current setup each raidz in located on a different controller and each controller is plugged into a PCI-X slot on the MB. This, I thought, was the best way to load-balance throughput. However I've done more reading and now my thoughts are to combine all HD's on one controller and create one zpool.
Is their merit to having all HD's on one controller or is it better to spit up the zpool over 2 controllers?
Does anyone have experience with this?
Thanks in advance
