2.2.1 Installation Strategy

A successful installation of DSR requires careful planning and assessment of all configuration materials and installation variables.

• An overall installation requirement is decided upon the following data:
  • The total number of sites.
  • The number of virtual machines at each site and their role(s).
  • What time zone should be used across the entire collection of DSR sites?
  • If the SNMP traps be viewed at the NOAM or if an external NMS can be used or in some cases both.
• A site survey (NAPD) is conducted with the customer to determine exact networking and site details.

  Note:

  XMI and IMI addresses are difficult to change once configured. It is very important these addresses are well planned and not expected to change after a site is installed.

DSR currently supports the following installation strategies:

• DSR installation without using HEAT templates

  DSR Single Site Installation Procedure Map Without Using HEAT Templates figure illustrates the overall process that each DSR installation involves. In summary, this involves creation of guests and configures each guest role based on Resource Profile and Configure Network.

• DSR installation using HEAT templates (OpenStack)

  DSR Installation Procedure Map Using HEAT Templates figure illustrates the overall process that each DSR installation involves using the Heat Templates. It involves creation of parameter files, environment files, template files, DSR Topology Configuration xml and deploys DSR using OpenStack CLI commands.
