Application Scenarios

EC (Erasure Code) is a data protection method. The original data is divided into K data blocks (the K data blocks form a strip), and M redundant blocks are generated after the data blocks are encoded. You can restore the original data by using any K blocks in the K+M blocks. You can store data blocks and redundant blocks in different locations. Ceph data storage pools are classified into two types: copy and EC. EC Turbo optimizes the performance of EC data storage pools.
