[Gluster-users] GlusterFS absolute max. storage size in total?

[Peter B.]

Thanks Amar and Mohamed!

My question was mainly aiming at things like programmatical limitations.
We're already running 2 Gluster-Clusters with 4 nodes each.
3 bricks = 100 TB/node = 400 TB total.

So with Gluster 3.x it's 8PB, possibly more with Gluster 4.x.

Right?


Thank you very much again!
Peter B.
