[Gluster-users] Mixing transport-types?

I have 4 gluster storage nodes, they have both IB and ETH. Since this
gluster storage should be used for cluster, problem is that cluster
nodes have IB and cluster frontend has ETH. So in theory cluster nodes
could mount gluster via IB, and frontend via ETH, right?
Running two or more gluster clients with different transport type (if
gluster storage nodes are set to run via IB and ETH) will not cause any

The gluster clients where the mounts are done are usually application servers.

Might as well use that to connect to some of the clients which are going to run important application servers ( just a suggestion ).
