Some platform configuration requirements are common to all NSP deployment types, as described in Common deployment configuration elements.

When the platform configuration is complete, see NSP deployment information map. for the topics that are relevant to your deployment path.

The following topics outline the final platform configuration actions required before you deploy the NSP software.

Note: Depending on the OS installation method in a new or expanded deployment, the order in which you deploy the OS and partition the disks varies, as described below.

Disk partitioning

A physical component or VM that hosts NSP software requires a specific disk partitioning scheme. For a new or expanded deployment, when you establish the partitions depends on the OS deployment method, and is one of the following:

• during NSP OEM image deployment, as described in NSP disk-image deployment

• after a manual RHEL OS installation; see one of the following, based on your deployment environment:

  • Disk partitioning for trial deployments

  • Disk partitioning for live deployments

For a deployment upgrade, you must ensure that the current disk partitions on each component are of sufficient capacity as defined for the new NSP release.

OS deployment

You must deploy or update each component OS, as required.

• new or expanded system—install the OS on each new NSP VM and component on physical hardware using one of the following methods; see Chapter 3, RHEL OS deployment for the NSP:

  • deploy a Nokia OEM disk image

  • manually install the OS

• system or component upgrade—apply the latest update to each OS instance as described in the following, depending on the OS deployment method:

  • To apply a RHEL update to an NSP image-based OS

  • To apply a RHEL update to a manually deployed OS

Security

The NSP is a highly secure system that has stringent security requirements. Chapter 4, Configuring NSP security describes how to configure and deploy TLS for the NSP, and provides information about system-level and application-level user accounts and authentication.

NSP network management environment

Chapter 5, NSP deployment basics describes the NSP Kubernetes infrastructure and includes Kubernetes upgrade procedure To upgrade the NSP Kubernetes environment. The chapter also describes aspects of internal and external system communication such as IP-version support and optional logging options that include remote forwarding.

Note: Typically, the NSP Kubernetes environment requires an upgrade before you can upgrade the NSP software.

Chapter 6, NSP software configuration explains how to set the NSP deployment parameters and enable specific NSP functions that may require additional configuration.

The NSP Installation and Upgrade Guide topics of interest vary depending on the current and projected deployments. The information in Table 1-2, Guide topics by deployment path can help you identify the relevant topics based on your proposed deployment path, and identify chapters and topics that are not of interest. The topics are listed in the order that best defines the overall flow of deployment operations.

Note: The table provides a high-level path through NSP Installation and Upgrade Guide topics; you are strongly encouraged to also read any topic overview material that is not explicitly listed.

Note: The NSP system upgrade procedure include references to topics in Chapter 14, NSP component upgrade for upgrading ancillary components.
