New data storage: Ceph
This post is over 5 years old, it may be out of date.
Recently C&CZ presented an extra choice for data storage, next to the traditional RAID storage on individual fileservers: Ceph. The main advantages of Ceph are, that is scales almost without limits and does not have a single point of failure, but instead is “self-healing” and “self-managing”. Within Ceph storage, choices can be made, the more expensive ones have no problem when a complete datacenter goes down. The Ceph storage can also be used as S3-storage. Because of the cluster setup, performance of Ceph storage can be surprising: writing is in general faster than reading, especially with many small files, Ceph can be much slower than traditional storage. If you want to try whether Ceph suits you, please contact C&CZ.
