What is a cluster in computer storage?

1) In a computer system, a cluster is a group of servers and other resources that act like a single system and enable high availability and, in some cases, load balancing and parallel processing. Any file stored on a hard disk takes up one or more clusters of storage.

What is a disadvantage of clustering?

Disadvantages of clustering are complexity and inability to recover from database corruption. In a clustered environment, the cluster uses the same IP address for Directory Server and Directory Proxy Server, regardless of which cluster node is actually running the service.
