[Gluster-users] Network Topology Question

[Patrick Ernst]

Hi there,

I'm planning to setup a 3-Node Cluster for oVirt and would like to use 56 GBe (RoCe) 
exclusively for GlusterFS. Since 56 GBe switches are far too expensive and  it's not 
planned to add more nodes and furthermore this would add a SPOF I'd like to 
cross connect the nodes as shown in the diagram below:

Node 1   Node 2    Node3
  ||_______||________||
  |___________________|

This way there's a dedicated 56 Gbit connection to/from each member node. 

Is is possible to do this with GlusterFS? 
My first thought was to have different IPs on each node's /etc/host mapped to the node 
hostnames but I'm unsure if I can force GlusterFS to hostnames instead of IPs.

Patrick
