PC Solutions toNetwork File Systems
2
The Industry

• PC Architectures continue to improve in
  performance and reliability
• Lower cost for hardware implementation
• Access required from off site locations
• PCs are moving into the back office

3
What They Want

• Single solution to file access
• Ability to access information from anywhere
• Simple and easy to use

4
The Industry

• TCP/IP defacto standard for networking protocol
• NFS becoming Industry Standard Protocol for file
  sharing
• Transparent Access allowing users the ability to
  use existing knowledge

5
The Solution NFS V4

• Network Latency and firewall traversal
• Recovery controls for Lockd
• Security
• Kerberos 5
• Simplifies the PC users access to this
  information using their existing knowledge
• Crash recovery and file sharing capabilities for
  PC NFS Clients
• Volatile File Handles
• Named Attributes

6
What Else

• Multiple roots
• Mount point crossing

7
The Other Choices

• SMB
• SAMBA and CIFS
• Non standard add-on protocol
• Resource and Network intensive
• UNIX implementation is difficult to administer
  and unstable

8
The Future

• Continued growth in the NFS market is expected as
  more industries standardize on NFS for file
  sharing and document management
• With the current capabilities of PC architectures
  the need for PC NFS Clients and Servers will
  increase
• More platform independent software requirements
• Internet growth extends accessibility

9
In Conclusion

• Larger install base covering wide areas requires
• Security
• Firewall transversal
• Network Latency Support
• Simplified use in multi vendor and multi OS
  environments
• Crash Recovery and Sharing allows for
  heterogeneous environment
• PC NFS Client and Server Market will extend
