Quick-And-Easy Deployment of a Ceph Storage Cluster with SLES with a Look at SUSE Studio, Manager and Build Service
Quick-and-Easy Deployment of a Ceph Storage Cluster with SLES With a look at SUSE Studio, Manager and Build Service Jan Kalcic Flavio Castelli Sales Engineer Senior Software Engineer [email protected] [email protected] Agenda Ceph Introduction System Provisioning with SLES System Provisioning with SUMa 2 Agenda Ceph Introduction SUSE Studio System Provisioning with SLES SUSE Manager System Provisioning with SUMa 3 Ceph Introduction What is Ceph • Open-source software-defined storage ‒ It delivers object, block, and file storage in one unified system • It runs on commodity hardware ‒ To provide an infinitely scalable Ceph Storage Cluster ‒ Where nodes communicate with each other to replicate and redistribute data dynamically • It is based upon RADOS ‒ Reliable, Autonomic, Distributed Object Store ‒ Self-healing, self-managing, intelligent storage nodes 5 Ceph Components Monitor Ceph Storage Cluster Object Storage Device (OSD) Ceph Metadata Server (MDS) Ceph Block Device (RBD) Ceph Object Storage (RGW) Ceph Clients Ceph Filesystem Custom implementation 6 Ceph Storage Cluster • Ceph Monitor ‒ It maintains a master copy of the cluster map (i.e. cluster members, state, changes, and overall health of the cluster) • Ceph Object Storage Device (OSD) ‒ It interacts with a logical disk (e.g. LUN) to store data (i.e. handle the read/write operations on the storage disks). • Ceph Metadata Server (MDS) ‒ It provides the Ceph Filesystem service. Purpose is to store filesystem metadata (directories, file ownership, access modes, etc) in high-availability Ceph Metadata Servers 7 Architectural Overview 8 Architectural Overview 9 Deployment Overview • All Ceph clusters require: ‒ at least one monitor ‒ at least as many OSDs as copies of an object stored on the cluster • Bootstrapping the initial monitor is the first step ‒ This also sets important criteria for the cluster, (i.e. -
