Software-defined storage (SDS):
Software-defined storage (SDS) is an evolving concept for computer data storage software to manage policy-based provisioning and management of data storage independent of hardware.
Software-defined storage definitions typically include a form of storage virtualization to separate the storage hardware from the software that manages the storage infrastructure. The software enabling a software-defined storage environment may also provide policy management for feature options such as deduplication, replication, thin provisioning, snapshots and backup
Ceph is a distributed object store and file system designed to provide excellent performance, reliability and scalability. On storage side it is very flexible as it support three type of storage :
Ceph provides seamless access to objects using native language bindings or radosgw, a REST interface that’s compatible with applications written for S3 and Swift.
Ceph’s RADOS Block Device (RBD) provides access to block device images that are striped and replicated across the entire storage cluster.
Ceph provides a POSIX-compliant network file system that aims for high performance, large data storage, and maximum compatibility with legacy applications.
GlusterFS is an open source, distributed file system capable of scaling to several petabytes and handling thousands of clients. GlusterFS clusters together storage building blocks over Infiniband RDMA or TCP/IP interconnect, aggregating disk and memory resources and managing data in a single global namespace. GlusterFS is based on a stackable user space design and can deliver exceptional performance for diverse workloads.
