Reliability / Resilience Most of the distributed Storage solutions take care of its fault-tolerance by design. They also have capability to replicate the data stored for any un-foreseen event. Due to its distributed nature, the data is not stored on the same node and is distributed among various nodes of the cluster and each node is further replicated, depending on number of replicas defined by Cluster admin. Almost all of them also have data sanity check so that data stored is also checked for any corruption.In Distributed data storage,it is the function of Software Defined Storage system to ensure that everything is divided, distributed, replicated and in-case of any issue, rectified with intelligent algorithm created by admins.
