With block, object, and file storage combined into one platform, Red Hat Ceph Storage efficiently and automatically manages all your data. Ceph Block storage Based upon RADOS, Ceph Storage Clusters consist of two types of daemons: a Ceph OSD Daemon (OSD) stores data as objects on a storage node; and a Ceph Monitor (MON) maintains a master copy of the cluster map. However, this can get difficult with too many clusters on a large scale. This is the only component of the Ceph cluster where actual user data is stored, and the same data is retrieved when the client issues a read operation. Ceph is open source, software-defined storage maintained by RedHat. A Ceph Storage Cluster may contain thousands of storage nodes. Ceph Storage Clusters can be sized for different performance levels by designing the performance capabilities of the servers and storage type used in the nodes that make up the cluster. And now, it’s more and more understood that a lot of that power comes from its flexibility. Storage infrastructure is undergoing tremendous change, particularly as organizations deploy infrastructure to support big data and private clouds. It mainly focuses on scale-out file system including storage distribution and availability. These requests are delivered with the perfect combination of right sense of fact-oriented problem solving methodologies and leveraging existing data repositories. While Ceph runs on commodity hardware, this fact DOES NOT mean selecting the cheapest hardware possible is necessarily a good idea. Ceph is an open-source distributed software platform 1 2. OpenShift Container Platform clusters can be provisioned with persistent storage using Ceph RBD. Also, this distributed detection helps in quick detection and resolving inconsistencies.
