-It is possible to install the {ceph} storage server directly on the
-Proxmox VE cluster nodes. The VMs and Containers can access that
-storage using the xref:ceph_rados_block_devices[Ceph RADOS Block Devices (RBD)]
-storage driver.
+{pve} unifies your compute and storage systems, i.e. you can use the
+same physical nodes within a cluster for both computing (processing
+VMs and containers) and replicated storage. The traditional silos of
+compute and storage resources can be wrapped up into a single
+hyper-converged appliance. Separate storage networks (SANs) and
+connections via network (NAS) disappear. With the integration of Ceph,
+an open source software-defined storage platform, {pve} has the
+ability to run and manage Ceph storage directly on the hypervisor
+nodes.

+Ceph is a distributed object store and file system designed to provide
+excellent performance, reliability and scalability. For smaller
+deployments, it is possible to install a Ceph server for RADOS Block
+Devices (RBD) directly on your {pve} cluster nodes, see
+xref:ceph_rados_block_devices[Ceph RADOS Block Devices (RBD)]. Recent
+hardware has plenty of CPU power and RAM, so running storage services
+and VMs on the same node is possible.
