  1. Chapter Nine NetWare-Based Networking

  2. Introduction to NetWare • In 1983, Novell introduced its NetWare network operating system • Versions 3.1 and 3.1—collectively known as NetWare 3.x—were introduced in the early 1990s • Versions 4.0, 4.1, and 4.11—collectively known as NetWare 4.x—were introduced in the mid-1990s • NetWare 4.11 is sometimes referred to as IntraNetWare • In 1998, Novell released version 5.0, and since has released versions 5.1 and 5.11—collectively known as NetWare 5.x • Today – NetWare 6.5

  3. Introduction to NetWare • 1995 • Microsoft introduces Windows NT Server • NetWare 52.5% market share • MS 6.3% • 1997 • Win NT 36% • NetWare 26.4% • Unix 20.7% • Linux 6.8% • OS/2 6.3%

  4. NetWare Server Hardware Table 9-1: Minimum hardware requirements for NetWare 4.x and 5.0 servers

  5. Windows 2000 Server Hardware - Comparison

  6. Determining the Optimal Hardware for a Server • When considering NetWare, note the number of NetWare loadable modules (NLMs) used by each service • NLMs are routines that enable the server to run a range of programs and offer a variety of services • Each NLM consumes some of the server’s memory and processor resources (at least temporarily)

  7. A Closer Look at the NetWare Operating System • Multiprocessing • In versions 4.x and higher, NetWare supports the use of as many as 32 processors on one server • Takes advantage of symmetric multiprocessing • To use NetWare 5.x’s multiprocessing capabilities, simply install multiple processors in the server

  8. NetWare’s Memory Model • Whereas NetWare 4.x can use only physical memory, NetWare 5.x can work with both virtual memory and physical memory • Protected mode • A manner in which NetWare runs services in a separate memory area from the operating system • Caching • Process of saving frequently-used data to an area of the physical memory where it will be readily available for future purposes

  9. The Kernel and Console Operations • Kernel • Core of the operating system • Server console • Network administrator’s primary interface to a NetWare server • 4.x not entirely graphical • 5.x text or graphics-based system • Monitor • NLM that enables the system administrator to view server parameters such as protocols, bindings, system resources, and loaded modules

  10. The Kernel and Console Operations Figure 9-1: NetWare console screen at the Monitor menu

  11. The NetWare File System • NetWare does not allow you to specify the file system types in the same way that Windows 2000 does • It does offer its own high-performance file system that supports DOS, Macintosh, UNIX, OS/2, and Windows

  12. Compression • NetWare 4.x and 5.x both support file compression • In both NetWare 4.x and 5.x, unless the network administrator specifically chooses to prevent compression, compression on the server is enabled automatically • Compression does increase file access time slightly; for this reason it is not recommended for extremely large files

  13. Block Suballocation • Technique for using hard disk space more efficiently • Block • Unit of disk space Figure 9-2: Block suballocation

  14. NetWare Directory Services (NDS) • Provides a system for managing multiple servers and their resources • NDS tree • The logical representation of resources in a NetWare enterprise Figure 9-3: Simple NDS tree

  15. NetWare Directory Services (NDS) • Container Objects • Hierarchical arrangement of branches • Also called organizational units Figure 9-4: Two ways of grouping objects in an NDS tree

  16. NetWare Directory Services (NDS) Figure 9-5: More complex NDS tree

  17. Planning for Installation • Where does the server fit in the NDS tree? • What name will the server have? • How many and what kinds of network adapter cards will the server use? • What protocols and network services should the server use? • What kind of disk controllers does the server have?

  18. Planning for Installation • How many, how large, and what kind of volumes will the server require? • What additional services will the server support? • In a simple installation, the most popular installation options are already chosen • In custom installation, it’s possible to determine which services and programs are installed • What kind of license do I have? • How can I remember all of this information?

  19. The Installation Process • NetWare can be installed from: • CD (most popular method) • Floppy disks (not recommended) • Another server on the network • This process is called an “over-the-wire” installation

  20. The Installation Process • After performing a NetWare 5.x installation and restarting the machine, your server should be functional • After installing a NetWare server, verify that you can log on to that server as administrator from a Windows 2000 or Windows 9x workstation using the Novell Client for NetWare

  21. Using the NetWare Administrator Utility (NWAdmin) • To make you server functional, you will need to add users and other objects to the NDS tree • After adding objects, you may want to modify their properties or even delete them • An important tool in NetWare server management is the NetWare Administrator utility (NWAdmin)

  25. Using the NetWare Administrator Utility (NWAdmin) • You will find that your most frequent use of NWAdmin consist of: • Viewing objects • Modifying objects • Creating objects • In short, NWAdmin is your link to managing your NDS tree

  26. Internetworking with Other Operating Systems • NDS eDirectory • Works with NetWare 5.x operating systems and Windows NT or 2000 servers to enable Windows domains to appear as container objects in NWAdmin • Provides a simple solution to a network administrator's challenge of integrating Windows 2000 and NetWare

  27. Internetworking with Other Operating Systems • On the client side, Novell provides client software designed specifically for: • Windows 2000 • Windows NT • Windows 9x • OS/2 • Macintosh • UNIX
