We have 4 offices with ipsec lan2lan over fibre net (20-100 mbit on eache office, except one office with 10 mbit fibre). Latency is below 20 ms (between to of the offices with fastest network we have 2 ms). All offices have lan2lan between each other.
iperf between offices is typical 50-80 mbit.
We will have 0,5 - 1 tb data with little daily changes.
Is it recomended to use Geo-replication, or normal gluster replication?
