Benefits to the enterprise
Enterprises today struggle to manage the explosive growth of data while remaining agile and costeffective. To manage petabytes of data at the speed required by today’s business, enterprises must use cloud technology to store their data. Designed for the cloud, Red Hat Ceph Storage significantly lowers the cost of storing enterprise data and helps manage exponential data growth—efficiently, automatically, and economically. Delivered in one self-healing, self-managing platform with no single point of failure, Red Hat Storage handles data management so enterprises can focus on data availability.
Features
Exabyte Scalability
- Scale-out architecture. Grow a cluster from one node to thousands.
- Automatic rebalancing. Use a peer-to-peer architecture to add capacity at any time with minimal operational effort. Say goodbye to forklift upgrades and data migration projects.
- Hot or phased software upgrades. Upgrade clusters in phases with no or minimal downtime. API
- S3 and Swift API. Supports object storage.
- RESTful API. Manages all cluster and object storage functions.
Storage-Aware webscale applications (object only)
- Development libraries for direct application integration. Allows such advanced functions as triggers, message passing, and in-situ data transformations.
- High-performance native protocol. Removes the overhead of the RESTful interface for performance- sensitive software that needs low latency and high throughput I/O.
Security
- Access control lists. Exert granular control over object storage user and bucket-level permissions.
- Quotas. Prevent abuse with pool or object user storage limits.
Reliability and Availability
- Dynamic block resizing. Expand or shrink Ceph block devices with no or minimal downtime.
- Striping, erasure coding, or replication across nodes. Enjoy data durability, high availability, and high performance.
- Storage policies. Configure placement to reflect SLAs, performance requirements, and failure domains.
- Data placement. Use the CRUSH algorithm to allow every client to calculate where data is located without needing lookup tables and speed performance.
- Automatic failover. Prevent server or disk failures from impacting data integrity, availability, or performance.
Peformance
- Copy-on-write cling. Provision virtual machine (VM) images quickly (block only).
- In-memory client-side caching. Cache both kernel and hypervisor (block only).
- Improved parallelism for data I/O. Leverage a client-cluster model, instead of a client-server one.
- Cache tiering. Promote hot data to SSDs with expiration policies.
- Flash journals. Enhance the write performance of data.
- Customizable stripe sizes. Configure optimal system performance, whether storing multi-gigabyte video files or small pictures.
Multi-datacenter support and disaster recovery
- Zones and region support. Deploy topologies similar to Amazon Web Services S3, and others, with a global namespace (object only).
- Read affinity. Serve local copies of data to local users (object only).
- Datacenter synchronization. Back up full or partial sets of data between regions (object only).
- Export snapshots to geographically dispersed datacenters. Institute disaster recovery (block only).
- Export incremental snapshots. Minimize network bandwidth (block only).
Cost effectiveness
- Thin provisioning. Allow for over-provisioning (block only)
- Commodity hardware. Tailor the price/performance mix to the workload.
- Heterogeneous hardware. Avoid having to replace older nodes as newer ones are added.
- Erasure coding. Enjoy the value of a cost-effective data durability option.
Web based management
- Ceph management platform. Get a dashboard for cluster operations.
- Per-disk and per-pool performance statistics. Spot bottlenecks quickly and easily.
- Diagnostics workbench. Speed up troubleshooting.
