Hardware raid with ZFS should avoided
ZFS needs direct access to disks and with hardware raid you have a controller in the middle
If you need ZFS, skip the hardware raid and use ZFS raid

Hi,Since I am new with Gluster, need your advices. I have 2 different Gluster configuration:Purpose: Need to create 5 Gluster volumes. I am running the gluster version is 3.9.0.Config #1: 5 bricks from one zpool
- 3 storage nodes.
- Using hardware raid to create one array with raid5 (9+1) per storage node
- Create a zpool on top of the array per storage node
- Create 5 ZFS shares (each share is a brick) per storage node
- Create 5 volumes with replica of 3 using 5 different bricks.
Config #2: 1 brick from one zpool
- 3 storage nodes.
- Using hardware raid to create one array with raid5 (9+1) per storage node
- Create a zpool on top of the array per storage node
- Create 1 ZFS shares per storage node. Using the share as brick.
- Create 5 volumes with replica of 3 with same share.
1) Is there any different on the performance on both config?2) Will the single brick be handling parallel writing vs multiple brick?3) Since I am using hardware raid controller, any option that I need to enable or disable for the gluster volume?Best Regards,~ Vic Le
