21.3. Network

Data traffic Network becomes a bottleneck as and when number of storage nodes increase. By adding a 10GbE or faster network for data traffic, you can achieve faster per node performance. Jumbo frames must be enabled at all levels, that is, client, Red Hat Gluster Storage node, and ethernet switch levels. MTU of size N+208 must be supported by ethernet switch where N=9000. We recommend you to have a separate network for management and data traffic when protocols like NFS /CIFS are used instead of native client. Preferred bonding mode for Red Hat Gluster Storage client is mode 6 (balance-alb), this allows client to transmit writes in parallel on separate NICs much of the time.
