What is CEPH Storage ? Best Cloud Storage Solution

CEPH is one of the best cloud storage solution. It delivers object, block and file storage under same environment.It is highly reliable and easy to manage and open source. It benefits lot of big companies which has huge data in petabyte. It is highly scalable infrastructure for storage.

RADOS(Reliable Autonomic Distributed Object Store) is the core component of CEPH. In order to build CEPH storage cluster you will require one Ceph Monitor, Ceph Manager, and Ceph OSD (Object Storage Daemon). The Ceph Metadata Server is also required when running Ceph Filesystem clients.

Ceph Monitor – Ceph Monitor maintains the several maps like monitor map, manager map, OSD map and the CRUSH map. These maps are very important in order to make the ceph daemons to coordinate with each other. It is also responsible for managing authentication between daemons and clients. In order to have redundancy and high availability, you need to have min three monitors.

Ceph Manager – For high availability yo ucan have two managers. Ceph Manager daemon is responsible for keeping track of runtime metrics and the current state of the Ceph cluster, including storage utilization, current performance metrics, and system load.

Ceph OSDs – Ceph OSD stores data, handles data replication, recovery, rebalancing, and provides some monitoring information to Ceph Monitors and Managers by checking other Ceph OSD Daemons for a heartbeat. At least 3 Ceph OSDs are normally required for redundancy and high availability.

MDSs – Ceph Metadata Server stores metadata on behalf of the Ceph Filesystem.

Ceph stores data as objects within logical storage pools. Using the CRUSH algorithm, ceph calculates which placement group should contain the object, and further calculates which Ceph OSD Daemon should store the placement group. The CRUSH algorithm enables the Ceph Storage Cluster to scale, rebalance, and recover dynamically.

You can enable the CEPH Storage solution in Enterprise Private Cloud Server. Highly scalable storage solution is very important in order to store petabytes data.

SiliconHouse Enterprise Cloud Server is flexible and easy to manage. Ceph Storage can be easily integrated along with SiliconHouse Enterprise Cloud Server.
