Appendix D. Example deployment using 6 hyperconverged nodes This section contains example files for a 6 node deployment of Red Hat Hyperconverged Infrastructure for Virtualization. These example files have the following assumptions: All nodes have the same disks and are configured identically. Each node has 5 devices: a boot device ( sda ), three storage devices ( sdb , sdc , and sdd ) and a fast cache device ( sde ). The engine volume uses the sdb device on all nodes. This device is thickly provisioned. The data volume uses the sdc device on all nodes. This device is thinly provisioned and has a fast cache device sde attached to improve performance. The vmstore volume uses the sdd device on all nodes. This device uses multipath configuration, is thinly provisioned, and has deduplication and compression enabled. This cluster uses IPv6 networking.
