Welcome to Ceph
|
|
=================
|
|
|
|
Ceph uniquely delivers **object, block, and file storage in one unified
|
|
system**. Ceph is highly reliable, easy to manage, and free. The power of Ceph
|
|
can transform your company's IT infrastructure and your ability to manage vast
|
|
amounts of data. Ceph delivers extraordinary scalability--thousands of clients
|
|
accessing petabytes to exabytes of data. Ceph leverages commodity hardware and
|
|
intelligent daemons to accommodate large numbers of storage hosts, which
|
|
communicate with each other to replicate data, and redistribute data
|
|
dynamically. Ceph's cluster of monitors oversees the hosts in the Ceph storage
|
|
cluster to ensure that the storage hosts are running smoothly.

|
**One Object Storage:** The Ceph Object Store, called RADOS, is the
|
|
object storage component for CephFS filesystems, Ceph RADOS Gateways, and
|
|
Ceph Block Devices.
|
|
|
|
**Many Storage Interfaces:** You can use CephFS, Ceph RADOS Gateway, or Ceph
|
|
Block Devices in your deployment. You may also use all three interfaces
|
|
with the same Ceph Object Store cluster! There's no reason to build three
|
|
different storage clusters for three different types of storage interface!
|
|
|
|
**Use Commodity Hardware!:** You can deploy Ceph with commodity hardware.
|
|
You don't need to purchase proprietary storage or networking hardware
|
|
commonly used in :abbr:`SAN (Storage Area Network)` systems.
