Chapter 1 Sun Open Telecommunications Platform Introduction

This chapter provides an overview of Open Telecommunications Platform (OTP) features and components, and a high-level summary of the steps required to install the Open Telecommunications Platform.

The following topics are discussed:

• Open Telecommunications Platform Features

• Open Telecommunications Platform Hardware Components

• Open Telecommunications Platform Installation Summary

Open Telecommunications Platform Features

The Open Telecommunications Platform OTP provides integrated high availability services, system management services , and operating system and application provisioning services that enable you to develop, deploy, and host network equipment provider (NEP) applications. The Open Telecommunications Platform is comprised of the following software components:

OTP system management service

The OTP system management service is used to provision the OS to OTP hosts, and to manage the OTP hardware, the operating systems running on the OTP hardware, and the firmware necessary for hardware operation. The management software is comprised of operational elements and administrative elements.

OTP application provisioning service

The OTP application provisioning service is used to provision network equipment provider (NEP) applications. OTP application provisioning service can also be used to provision the OS to OTP hosts.

OTP high availability framework

The OTP high availability framework is used to manage OTP system membership, interconnects, networking quorums and highly available OTP deployments.

The Open Telecommunications Platform enables you to perform the following tasks:

• Discover additional OTP hosts that are to be managed and provisioned by the Open Telecommunications Platform system. Once discovered, each new host is known as an OTP host.

• Provision operating systems to OTP hosts.

• Provision NEP applications and other applications to OTP hosts.

• Provision firmware and patches to OTP hosts.

• Monitor the health of OTP hosts.

• Simplify OTP host configuration and recovery.

• Maximize OTP host utilization

• Minimize user-visible hardware downtime.

• Log system and OTP host events.

Open Telecommunications Platform Hardware Components

The following figure provides a high-level overview of the hardware components of the Open Telecommunications Platform.

Figure 1–1 Open Telecommunications Platform Architecture

10/100 Mbit Ethernet minimum is required by the management network. 10/100/1000 Mbit Ethernet is required by the provisioning and the data networks.

The above diagram represents one of the possible clustered OTP system configurations. In a standalone OTP host configuration, only the first OTP host is present.

The following list describes each of the Open Telecommunications Platform components.

• External OTP installation server

  A non-clustered server that is used to install the Open Telecommunications Platform software for the first time to an OTP host.

• First OTP host

  The first host in a clustered OTP system on which the Open Telecommunications Platform is installed. A standalone OTP host is comprised only of the first OTP host.

• Additional OTP hosts

  One or more secondary hosts within a clustered OTP system that provide high availability. Additional OTP hosts are managed and monitored using the OTP high availability framework and the OTP system management service. Network Equipment Provider (NEP) applications can be provisioned to the OTP hosts using the OTP application provisioning service.

Open Telecommunications Platform Installation Summary

Installation of the Open Telecommunications Platform is comprised of the following major steps.

• Site preparation

  Ensure that your equipment meets the requirements listed in OTP System Hardware and Firmware Requirements.

• Record your Open Telecommunications Platform Plan information

  Use the worksheets provided in Open Telecommunications Platform Plan Worksheets for each host to record the information that is applied by the Open Telecommunications Platform installation and configuration process. Plan information includes items such as management and provisioning interface ports, IP addresses for each OTP host, the clustered OTP system name, IPMP options, and more. Using the worksheets will assist you during installation and configuration, and reduce the chance for errors.

• Install the operating system on each server.

  Install and configure the Solaris 10 Update 2 operating system on external OTP installation server and on the servers selected for the Open Telecommunications Platform system as described in Chapter 3, Preparing Servers for Open Telecommunications Platform Installation.

• Set up the external OTP installation server

  The external OTP installation server must be set up as described in Setting Up the External OTP Installation Server before you can use the server to install the Open Telecommunications Platform for the first time.

• Install the Open Telecommunications Platform to the OTP systems.

  If you are installing the Open Telecommunications Platform for the first time, use either of the following two methods:

  • Install the Open Telecommunications Platform using the external OTP installation server and the command line as described in Chapter 4, Installing the Open Telecommunications Platform For the First Time Using the Command Line.

  • Install the Open Telecommunications Platform using the external OTP installation server and the graphical user interface (GUI) installation as described in Chapter 5, Installing the Open Telecommunications Platform For the First Time Using the Graphical User Interface.

  If you have already installed the Open Telecommunications Platform to a standalone OTP host or to a clustered OTP system, you can use a production OTP system to using install the Open Telecommunications Platform to a new OTP host as follows:

  • Install the Open Telecommunications Platform using the OTP provisioning service as described in Chapter 6, Installing the Open Telecommunications Platform Using the Provisioning Service On an Existing OTP System.

  • Install the Open Telecommunications Platform using the OTP system management service as described in Chapter 7, Installing the Open Telecommunications Platform Using the System Management Service On an Existing OTP System.
