Re: [Gluster-users] Arbiter node in slow network
As Alan mentioned latency is more important. Also consider using an SSD for all arbiter bricks and set maxpct (man 8 mkfs.xfs) to a high level (I prefer to use '90').

Hi Filipe, I think it would probably be fine. The Red Hat Storage docs list the important thing being *5ms latency*, not link speed: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/creating_arbitrated_replicated_volumes I haven't used an arbiter configuration yet (still stuck on distribute + replicate, not sure how to migrate).

Re: [Gluster-users] Arbiter node in slow network
As the arbiter doesn't receive or provide any data to the clients - just metadata ,so bandwith is not critical but lattency is.Ensure that lattency is the same or lower for the arbiter node and you can use an SSD/NVME to ensure that storage lattency won't be a bottleneck. Also, don't forget to specify the isize=512 and bump the 'maxpct' to a bigger number. Usually I set it to minimum 80%.
