Consistency maintenance
4
Q
List the key design issues for distributed file systems
A
Effective use of client caching: achieve performance equal to or better than that of local file systems
Consistency maintenance between multiple cached client copies
Recovery after server or client failure
Scalability and high throughput for read/write operations
