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?
