Yes I'm liking this more and more. Each of my servers have two network interfaces, and two disks. I can bond the network interfaces together (probably LACP), or put them on separate subnets (they are now for iscsi multipath) and use CRUSH map to distribute the data in such a way that the networks see similar load. In fact this probably happens automatically with uniform distribution across nodes. Some testing is in order I think.
