Parallel database systems store replicas of each data item (or partition) onmore than one node.a. Why is it a good idea to distribute the copies of the data items allocatedto a node across multiple other nodes, instead of storing all the copiesin the same node (or set of nodes).b. What are the benefits and drawbacks of using RAID storage instead ofstoring an extra copy of each data item?

Parallel and Distributed Storage

A parallel storage file system is a sort of clustered file system. A clustered file system is a storage system shared by multiple devices simultaneously.
