The Dell Technologies Reference Architecture for Red Hat OpenStack Platform includes Red Hat Ceph storage , which is a scale-out, distributed, software-defined storage system. The first is RADOS, a reliable autonomic distributed object store, which provides an extremely scalable storage service for variably sized objects. Ceph clients differ materially in how they present data storage interfaces. If that’s too cryptic, then just think of Ceph as a computer program that stores data and uses a network to make sure that there is a backup copy of the data. This model may improve Ceph’s interoperability, but it deviates from the originally intended design of NVMe/TCP fabric architectures. To try Ceph, see our Getting Started guides. Let’s take the make check performed by Ceph File System¶. Distributed object stores are the future of storage, because they accommodate unstructured data, and because clients can use modern object interfaces and legacy Our Red Hat Ceph Storage Architecture and Administration (CEPH125) tutors will give you a thorough understanding of the project management process and will assist you in studying for the exam.
