Why We Use Ceph
Ceph is a distributed storage system that provides highly scalable and reliable storage for our virtual machines, web hosting, and backup solutions. OneColo leverages Ceph's advanced features like data replication, automatic failover, and self-healing capabilities to ensure maximum uptime and data protection for our customers' critical workloads.
Ceph ensures data reliability through replication across multiple storage nodes, self-healing capabilities that detect and repair data corruption, and seamless failover if a node fails. This distributed architecture provides redundancy and high availability for VMs and data storage.
Ceph enhances performance through parallel I/O operations, intelligent data placement, and automatic load balancing. Its distributed architecture reduces latency by serving data from multiple nodes simultaneously, while the CRUSH algorithm optimizes data placement for faster access.
Ceph's distributed architecture enables seamless horizontal scaling by adding storage nodes without downtime. Its CRUSH algorithm automatically rebalances data across the cluster, while the object-based storage system eliminates traditional scaling bottlenecks.
Hows Does Ceph Work?
Ceph is a distributed storage system that operates on a cluster of servers, using a unique object-based storage architecture. At its core, Ceph uses a RADOS (Reliable Autonomic Distributed Object Store) layer that manages data distribution and replication across the cluster. The system employs a CRUSH (Controlled Replication Under Scalable Hashing) algorithm to determine data placement, ensuring even distribution and automatic rebalancing. Data is stored as objects within placement groups, which are distributed across multiple OSDs (Object Storage Daemons) for redundancy. The MON (Monitor) daemons maintain cluster maps and state, while MDS (Metadata Server) daemons handle metadata for file system operations. This architecture enables Ceph to provide seamless scaling, automatic failover, and self-healing capabilities while maintaining data integrity and high availability.
