1 Introduction to Ceph Storage for Oracle Linux Release 3.0

This chapter provides information on Ceph Storage for Oracle Linux Release 3.0.

About Ceph Storage for Oracle Linux Release 3.0

Ceph Storage for Oracle Linux Release 3.0 presents a uniform view of object and block storage from a cluster of multiple physical and logical commodity-hardware storage devices. Ceph can provide fault tolerance and enhance I/O performance by replicating and striping data across the storage devices in a Ceph Storage Cluster. Ceph's monitoring and self-repair features minimize administration overhead. You can configure a Ceph Storage Cluster on non-identical hardware from different manufacturers.

Ceph Storage for Oracle Linux Release 3.0 is based on the Ceph Community Luminous release (v12.2.5). Differences between Oracle versions of the software and upstream releases are limited to Oracle specific fixes and patches for specific bugs.

Note:

The source RPMs for Ceph are available from Oracle Linux yum server at https://yum.oracle.com.
