Ceph Features
Ceph offers the following features:
●
Exabyte scalability
◦
Scale-out architecture: Expand a cluster from one node to thousands.
◦
Automatic rebalancing: Use a peer-to-peer architecture to add capacity at any time with little
operational effort. You no longer need major equipment upgrades or data migration projects.
◦
Hot or phased software upgrades: Upgrade clusters in phases with little or no downtime.
●
API
◦
Amazon Web Services (AWS) S3 and OpenStack Swift API: Support object storage.
◦
REST API: Manage all cluster and object storage functions.
●
Storage-aware web-scale applications (object only)
◦
Development libraries for direct application integration: Access advanced functions such as triggers,
message passing, and in-place data transformations.
◦
High-performance native protocol: Eliminate the overhead of the REST interface for performance-
sensitive software that needs low-latency and high-throughput I/O.
●
Security
◦
Access control lists: Exert detailed control over object storage user- and bucket-level permissions.
◦
Quotas: Prevent abuse with pool and object user storage limits.
●
Reliability and availability
◦
Dynamic block resizing: Expand or shrink Ceph block devices with little or no downtime.
◦
Striping, erasure coding, and replication across nodes: Achieve data durability, high availability, and
high performance.
