-
- File Access |
- Common name space from all workstations |
- Different file names from different workstations |
-
-
- File Location Tracking |
- Automatic tracking by file system processes and databases |
- Mountpoints to files set by administrators and users |
-
-
- Performance |
- Client caching to reduce network load; callbacks to maintain cache consistency |
- No local disk caching; limited cache consistency |
-
-
- Andrew Benchmark (5 phases, 8 clients) |
- Average time of 210 seconds/client |
- Average time of 280 seconds/client |
-
-
- Scaling capabilities |
- Maintains performance in small and very large installations |
- Best in small to mid-size installations |
-
-
- Â |
- Excellent performance on wide-area configuration |
- Best in local-area configurations |
-
-
- Security |
- Kerberos mutual authentication |
- Security based on unencrypted user ID's |
-

- No replication |
-
-
- Backup Operation |
- No system downtime with specially developed AFS Backup System |
- Standard UNIX backup system |
-
-
- Reconfiguration |
- By volumes (groups of files) |
- Per-file movement |
-
-
- Â |
- No user impact; files remain accessible during moves, and file names do not change |
- Users lose access to files and filenames change (mountpoints need to be reset) |
-
-
- System Management |
- Most tasks performed from any workstation |
- Frequently involves telnet to other workstations |
-
-
- Autonomous Architecture |
- Autonomous administrative units called cells, in addition to file servers and clients |
- File servers and clients |
-
-
- Â |
- No trust required between cells |
- No security distinctions between sites |
