- 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

- Questions to ask when selecting a network operating system:
- Can it be integrated with existing infrastructure?
- Will it provide the security required by the network’s resources?
- Can the technical staff manage it effectively?
- Will existing applications run smoothly on it?
|
5
|
- Questions to ask when selecting a network operating system (cont.):
- Will it accommodate future growth (that is, is it scalable)?
- Does it support additional services the network’s users require?
- How much does it cost?
- What type of sort can be expected from the vendor?
|

7
|
- How many clients will connect to the server?
- What kind of applications will run on the server?
- How much storage space will each user need?
- How much down time is acceptable?
- What can the organization afford?
|

|
- 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)
|
9
|
- 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
|
10
|
- 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
|
11
|
- Kernel
- Core of the operating system
- Server console
- Network administrator’s primary interface to a NetWare server
- Monitor
- NLM that enables the system administrator to view server parameters
such as protocols, bindings, system resources, and loaded modules
|

|
- 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
|
14
|
- 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
|
15
|
- Technique for using hard disk space more efficiently
|
16
|
- Provides a system for managing multiple servers and their resources
- NDS tree
- The logical representation of resources in a NetWare enterprise
|
17
|
- Container Objects
- Hierarchical arrangement of branches
- Also called organizational units
|
18
|
|
19
|
- Can be envisioned as a kind of road map for finding an object in an NDS
tree
- Consists of an object’s organizational unit names plus the organization
name
- May be expressed in typeful or typeless notation
|
20
|
- Typeful notation
- Way of denoting an object’s context in which the Organization and
Organizational Unit designators are included
- Typeless notation
- Way of denoting an object’s context in which the Organization and
Organizational Unit designators are omitted
|
21

|
- 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?
|
23
|
- 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?
|
24
|
- 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
|
25
|
- 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
|
26
|
- 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)
|

|
- If you choose to establish a user’s home directory when creating that
user ID, that user will have all rights to his or her home directory by
default
- As a result, you do not have to assign Read, Write, Erase, or other
rights for the user’s home directory later
|
30
|
- After you have created NDS objects, you may want to change their
properties
- To view or change the properties of any leaf object:
- Right-click the object in the tree
- Choose Details from the menu that appears
|
31
|
|
32
|
- 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
|
33
|
- 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
|
34
|
- On the client side, Novell provides client software designed
specifically for:
- Windows 2000
- Windows NT
- Windows 9x
- OS/2
- Macintosh
- UNIX
|
35
|
- Currently, several versions of NetWare exist
- Both NetWare 4.1 and 5.x use NDS
- NetWare is optimal for file and print sharing
- NetWare offers native interoperability solutions for Macintosh-, DOS-,
Windows-, OS/2-, and UNIX-based systems
- NetWare may not suite every organization
|
36
|
- To determine the NetWare server’s requirements, consider the number of
(NLMs) used by each service
- Add components to a NetWare server to enhance its fault tolerance and
performance
- In versions 5.x and higher, NetWare supports up to 32 processors on one
server and uses symmetric multiprocessing
- Whereas NetWare4.x can use only physical memory, NetWare 5.0 can use
both physical and virtual memory
- At the heart of NetWare lies the kernel, or core of the operating system
|
37
|
- The network administrator’s primary interface to a NetWare server is the
server console
- NetWare uses volumes as the basis for organizing files and directories
on the server
- NetWare 4.x and 5.x both support file compression
- Block suballocation is a technique employed by NetWare for using hard
disk space more efficiently
- A major development that Novell introduced with version 4.0 is NDS
|
38
|
- Before inserting the NetWare CD for installation of the operating
system, consider the many factors the system will have
- NWAdmin is a graphical interface that runs from a Windows workstation
and enables network administrators to manage NDS objects
- The NDS eDirectory tool enables Windows 2000 domains to appear as
container objects in NWAdmin
