OpenStack doesn't combine CPU and RAM resources of several physical servers into one. With OpenStack, you can either manage virtual servers using hypervisors like KVM, Xen, Hyper-V or even ESX, each virtual server running inside one physical server. Or you can manage the physical servers directly with the Baremetal service. Or both in the same cloud.

On the other hand, you can combine all your storage into one, for example using Ceph or Sheepdog, and create and manage block devices from that storage pool with OpenStack. This won't be Raid 5; to protect the data, other technologies (in the case of Ceph Erasure Coding or replication) are used.
