Performance advantages of spool with 2x raidz2 vdev"s vs. Single vdev
Hi guys, I am about to reshape my data spool and am wondering what performance diff. I can expect from the new config. Vs. The old.
The old config. Is a pool of a single vdev of 8 disks raidz2.
The new pool config is 2vdev''s of 7 disk raidz2 in a single pool.
I understand it should be better with higher io throughput....and better read/write rates...but interested to hear the science
