Description: An EC group in distributed storage systems is a storage group that uses erasure coding to provide data redundancy and fault tolerance. This technique allows data to be divided into fragments and parity information to be added, facilitating data recovery in case of hardware failures. Erasure coding is particularly space-efficient, as it allows for the storage of large volumes of data with less overhead compared to traditional replication. In a distributed storage environment, EC groups are essential for ensuring data availability and durability, enabling systems to adapt to different performance and capacity needs. Additionally, the flexibility of erasure coding allows system administrators to adjust configurations based on specific workload characteristics, thus optimizing resource usage. In summary, EC groups in distributed storage systems are an advanced solution for data storage, combining efficiency, resilience, and scalability.
