  1. 21 Novell NetWare

  2. Fig. 21.1: NetWare is the server’s operating system. A NetWare module also runs on the client’s computer.

  3. Fig. 21.2: NetWare and the OSI model.

  4. Fig 21.3: NetWare keeps its kernel in memory and allocates the remaining memory for cache.

  5. Cache • Cache allocated as 4KB cache buffers • File cache buffers • hold data stored on disk • organized to form a linked list • most recently used buffers at top of list • least recently used buffers at bottom of list • Portion of cache is protected address space

  6. File Systems • NetWare file system • file allocation table • locate directory or file by following its path • mapped drives • Novell Storage Services (NSS) • for managing large amounts of data • Volume • basic object in either file system

  7. Fig. 21.4: A volume is divided into directories that contain files and subdirectories.

  8. Fig. 21.5: A directory or a file is located by following its path.

  9. Fig. 21.6: Hard disk partitions.

  10. Fault Tolerant Features • Disk duplexing • use of redundant disk as a mirror • Read after write • reread data just written to disk • compare against buffer • Hot fix • move data from bad sectors

  11. Printing Services • Queue based services • printers • print queues • print server • Novell distributed print services (NDPS) • efficient management

  12. Novell Directory Services (NDS) • A method of storing and retrieving service information in a distributed database. • Leaf objects • found at end of hierarchical tree structure • Container objects • hold other containers and leaf objects

  13. Fig. 21.7: NDS is organized logically as a hierarchical database.

  14. Rights • object rights • property rights • Partition • a logical division of a tree that contains one or more complete branches • Replication • the act of storing a copy of an NDS partition on a different server • provides for fault tolerance

  15. Network Management • Zero Effort Networks (ZENworks) • supports automation of network management • Application management • distribute and customize software • Workstation management • allows user to log onto multiple clients • Remote management • control user workstation from manager’s desktop
