Introduction to NetWare
• Novell released first NetWare in 1983
– NetWare versions prior to 4.11 require IPX/SPX
protocol suite
– Refined to run over TCP/IP in version 4.11

• NetWare 6.5’s key features:
– Support for multiple processors, multitasking, and
SMP

– Flexible use of virtual and physical memory
– eDirectory
– Simple, centralized management of multiple clients,
resources, and services

Introduction to NetWare (continued)
• NetWare 6.5’s key features (continued):
– Multiple, integrated Web development and delivery
services
– Support for multiple modern protocols
– Excellent integration with other NOSs and support
for many different clients
– Remote client services
– Built-in clustering services
– Provisions for monitoring server performance,
automatic backups, and resource utilization

Introduction to NetWare (continued)
• Noteworthy changes in NetWare 6.5:
– iManager
– DirXML
– Capability for continuously backing up a server

as it runs
– Server Consolidation Utility
– Popular open source Web development tools
– Virtual Office
– Branch Office
– Nterprise Linux Services

A Closer Look at the NetWare 6.5
Operating System: NetWare
Integrated Kernel
• Core of NetWare 6.5 OS
– Oversees all critical server processes
– Started by server.exe, which runs from server’s DOS
partition

• Takes advantage of SMP
– Up to 32 processors

• NetWare loadable modules (NLMs): Enable server
to run variety of programs and services
– Each consumes some of server’s memory and
processor resources
Network+ Guide to Networks, 4e

7


A Closer Look at the NetWare 6.5
Operating System: NetWare
Integrated Kernel (continued)
• Load or unload NLMs through server’s console
– Enables network administrator to manage disks and
volumes and modify server parameters
– Monitor: text-based menu system
– ConsoleOne: graphical menu system

• X Server: NetWare 6.5 server’s graphical desktop
• Remote Manager: access console commands via
Web browser on another network computer

NetWare File System
• Novell Storage Services (NSS):
–
–
–
–
–
–

–
–
–

64-bit interface
Files or directories up to 8 TB
A trillion files in single directory
File compression
User and directory space restrictions
Advanced fault-tolerance techniques
Efficient use of memory
Browser-based volume management
Split volumes over multiple storage devices

Network+ Guide to Networks, 4e

11


NetWare File System (continued)
• NSS-based system may have up to four partitions
– One must be a DOS partition
• Primary boot partition

– Unlimited volumes on each partition

• Volumes are basis for organizing files and
directories
• NSS can combine free storage space from multiple
storage devices into a storage pool

– Provides flexibility

• iManager: GUI tool used to manage objects

eDirectory
• NetWare 6.5’s directory database
– System for organizing and managing multiple
servers and their resources
– Similar to Active Directory in Windows Server 2003
• Treat every networked resource as separate object
with distinct attributes
• Objects belong to classes

• eDirectory information stored in database that
supports LDAP
– Compatible with other NOS and Internet directories
Network+ Guide to Networks, 4e

14


eDirectory (continued)

Figure 10-4: eDirectory objects

Network+ Guide to Networks, 4e

15


eDirectory (continued)
• Schema: defined set of object classes and their
properties
– Base schema: simple schema installed by default
with eDirectory
– Extended schema: changes made to base schema

• Trees and OUs:
– Hierarchical organization
– Tree can have one root
• Tree Object

Network+ Guide to Networks, 4e

16

eDirectory (continued)
• Trees and OUs (continued):
– Below root is an organization object
• Branches out in hierarchical arrangement of OUs

– A user is a leaf object

• Naming Conventions:
– Each eDirectory tree object has a context
• Indicates where object belongs in the tree
• Consists of object’s OU names, arranged from specific
to general, plus organization name

– Typeful and typeless contexts

Planning for Installation
• Poor planning results in more work for installer,
potential downtime for users, and headaches for
whomever supports server after installation

• Critical preinstallation decisions:
– Where does the server fit in the eDirectory tree?
• After server’s context established, cannot change it

– What name will the server have?
– How many and what kinds of NICs will the server
use?
– What protocols and network services should the
server use?
Network+ Guide to Networks, 4e

22


Planning for Installation (continued)
• Critical preinstallation decisions (continued):
– What will the Administrator password be?
– What kind of disk controllers does the server have?
– How many, how large, and what kind of volumes will
the server require?
• Initially all free space on hard disk assigned to default
volume, SYS

– What server pattern, or type, will the server be?
– What kind of license do I have?
– How can I remember all of this information?
