This paper discusses some policies for performance-reliability improvement in distributed file systems. File replication, file migration, and process migration are considered, and the decision whether to replicate a file, or to move a file or a process, is based on the workload demands on the system resources. The utilization of system components, especially that of the communication network, is important, and the system bottleneck and the hosts' bottlenecks are detected. A model of a distributed system is constructed and consists of a number of hosts connected by a communication network. Concurrency control policy allows transaction type access to the shared resources. A unit of concurrency control (i.e., entity to be locked) is a sector of a file. Concurrency control policy is a single writer or multiple readers. Two-phase locking protocol is used for transaction serialization.
