cluster
clustering

   1. <architecture> Multiple {servers} providing the same
   service.  The term may imply {resilience} to failure and/or
   some kind of {load balancing} between the servers.  Compare
   {RAIS}.

   2. <file system> An elementary unit of allocation of a {disk}
   made up of one or more physical {blocks}.

   A {file} is made up of a whole number of possibly
   non-contiguous clusters.  The cluster size is a tradeoff
   between space efficiency (the bigger is the cluster, the
   bigger is on the average the wasted space at the end of each
   file) and the length of the {FAT}.
