Factor 3 replicas introduced in CEPH-storage
We’ve implemented changes in the configurations of CEPH storage, which are used to provide power to CS1, Tier IV (SATA). These storages in the avz1 availability zone were transferred to factor 3 replication.
The replication factor is the level of data redundancy in the storage. There are three times more data copies on different nodes and disks. Every object in the storage is saved in three copies, each on a separate node. This update has significantly improved the reliability of the storage and increased its availability.
Our clients’ experience is our main priority. This is why we never stop working on our products, but continue to expand their features, optimize the services and fix the flaws within them.
