Re: [Gluster-users] stripe 2 replica 2 VS disperse 4 redundancy 2

Hola Manuel, as Ravishankar has said, you should use sharding instead of stripe. Regarding the disperse, the minimum number of servers you would need is 3. Disperse requires at least 3 bricks to create a configuration with redundancy 1 (this is equivalent to a replica 2 in terms of
