Ceph
Ceph is an open source, unified, distributed storage,
massively scalable system designed for excellent performance,
reliability and scalability.
Ceph's main goals are to be completely distributed without a
single point of failure, scalable to the exabyte level, and
freely-available. The data is seamlessly replicated, making it fault
tolerant.
It is comprised of an object store, block store, and a
distributed file system. Ceph runs on commodity
hardware, it is self-healing and self-managing, and has no single point
of failure.
Features include:
- RADOSGW - a bucket-based REST gateway, that is compatible
with applications written for S3 and Swif
- RADOS Block Device (RBD) - provides access to
block device images that are striped and replicated across the entire
storage cluster
- Ceph FS - provides a POSIX-compliant network distributed
file system, with a Linux kernel client and support for
FUSE. Ceph FS uses the same RADOS object storage device
system as RADOS block devices and RADOS object stores such as the RADOS
gateway with its S3 and Swift APIs, or native bindings
- RADOS - an autonomic, distributed object store. RADOS, is
the object storage component for CephFS filesystems, Ceph RADOS
Gateways, and Ceph Block Devices. Ceph's RADOS Object Stores
consist of two types of daemons: Object Storage Daemons (OSDs) store
data as objects on storage nodes; and Monitors maintain a master copy
of the cluster map
- Librados - a library allowing applications to directly
access RADOS
