Re: one brick vs multiple brick on the same ZFS zpool.

Hi,

How about hardware raid with XFS? I assuming it would be faster than ZFS raid since it has physical cache on raid controller for reads and writes.

Thanks,

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,
