Benefits of a Hyper-Converged Infrastructure (HCI) with {pve}
--------------------------------------------------------------
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-A hyper-converged infrastructure is especially useful for deployments
-in which a high infrastructure demand meets a low administration
-budget, for distributed setups such as remote and branch office
-environments or for virtual private and public clouds.

HCI provides the following advantages:
-- Scalability: seamless expansion of compute, network and storage
- devices (i.e. scale up servers and storage quickly and independently
- from each other).

+Hyper-Converged Infrastructure: Storage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+{pve} has tightly integrated support for deploying a hyper-converged storage
+infrastructure. You can, for example, deploy and manage the following two
+storage technologies by using the Webinterface only:
+
+- *ceph*: a both, self-healing and self-managing shared, reliable and highly
+ scalable storage system. Checkout
+ xref:chapter_pveceph[how to manage ceph services on {pve} nodes]
+
+- *ZFS*: a combined file system and logical volume manager with extensive
+ protection against data corruption, various RAID modes, fast and cheap
+ snapshots - among other features. Find out
+ xref:chapter_zfs[how to leverage the power of ZFS on {pve} nodes].
+
+Besides above, {pve} has support to integrate a wide range of
+additional storage technologies. You can find out about them in the
+xref:chapter_storage[Storage Manager chapter].
