Erasure coding (EC) is a data protection technique used in distributed storage systems. It provides redundancy and fault tolerance by dividing data into smaller fragments, adding parity information, and distributing these across multiple storage devices or nodes. C. Erasure Coding

C. Erasure Coding Erasure coding is a data protection method that provides the same level of fault tolerance as traditional replication but with lower storage overhead. It breaks data into fragments, expands it with redundant data pieces, and stores it across a set of different locations or storage media. This allows Nutanix to achieve efficient data protection with less storage usage compared to traditional replication.
