Planning for installation

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


Planning for installation continued

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?

Network+ Guide to Networks, 4e

  • NLMs are routines that enable the server to run a range of programs and offer a variety of services

Network+ Guide to Networks, 4e


Summary continued

Summary (continued)

  • Using ConsoleOne, administrators can manage servers, volumes, disks, and eDirectory objects

  • iManager is the primary means of managing eDirectory objects in NetWare 6.5

  • NSS offers many advantages over traditional file systems, including faster access, more efficient use of memory, file compression, support of files or directories as large as 8 TB, support for sharing a single application over multiple servers, capability to limit user directory and volume size, and browser-based management tools

Network+ Guide to Networks, 4e


Summary continued1

Summary (continued)

  • eDirectory is NetWare 6.x’s system for organizing and managing multiple servers and their resources, including storage devices, users, volumes, groups, printers, and so on

  • The word “schema” refers to eDirectory’s defined set of object classes and their properties

  • eDirectory follows a tree structure

  • Each object has a context that indicates where that object belongs in the eDirectory tree

  • NetWare recognizes two naming conventions for a user’s context: typeful and typeless

Network+ Guide to Networks, 4e


Summary continued2

Summary (continued)

  • User and Group objects can be created through ConsoleOne, Remote Manager, or iManager
