[Gluster-users] Brick layout question

[Strahil Nikolov]

Hi,
I doubt that dispersed volume will be faster as it needs to 'encode' some data during the writes.

Actually, if you don't need any redundancy and you work with large files -> you can test sharding xlator. Usually it's used for VMs and in your case the files will be sharded into small pieces (shards) spread among multiple bricks. Give it a try on a test volume first.
About the brick layout , I prefer to use 1 HW raid = 1 brick. For fast disks like NVMEs -> 1 NVME = 1 brick.
WARNING: ONCE SHARDING IS ENABLED, NEVER EVER DISABLE IT !


Best Regards,Strahil Nikolov

I've been running a multi-node single brick per node distributed array with the bricks being between 6 and 14TB each and getting okay performance.

I was reading some documentation and saw distributed dispersed as an option and was considering setting up a test array to see if that improved the performance.    I don't need replicas / redundancy at all for this array, just bulk storage.

My question, primarily, is about how to layout the bricks across six nodes with the ability to add additional nodes/drives as necessary.
Option 1:Single Brick Per Node

Option 2:
Multiple Bricks Per Node 
- Bricks a consistent size (1T each, left over disk as it's own brick)
- Bricks a fraction of the total disk (1/4 or 1/2)

Thank you for any suggestions/tips (links to additional documentation that would help educate me are welcome as well).________
