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:
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:
The OTP system management service is used to provision the OS and 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.
The OTP application provisioning service is used to provision network equipment provider (NEP) applications.
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.
The following figure provides a high-level overview of the hardware components of the Open Telecommunications Platform.
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 server that is used for a first-time installation of the Open Telecommunications Platform software to an OTP host using the OTP graphical user interface.
If you choose to install the Open Telecommunications Platform software manually using the command line, then the external OTP installation server is not required.
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.
In a clustered OTP system, the first OTP host DHCP service allocates IP addresses to the OTP hosts for use by the provisioning network. The OTP system management service uses the provisioning network to load operating systems and updates to the additional OTP hosts.
The Solaris OS DHCP service is the only DHCP service supported by Open Telecommunications Platform 1.0. ISC DHCP is not supported.
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.
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 the servers selected for the Open Telecommunications Platform system as described in Chapter 3, Preparing Servers for Open Telecommunications Platform Installation.
If you plan to install the Open Telecommunications Platform using an external OTP installation server, also install and configure the Solaris 10 Update 2 operating system on the external OTP installation server.
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 command line as described in Chapter 4, Installing the Open Telecommunications Platform Using the Command Line. An external OTP installation server is not required using this method.
Install the Open Telecommunications Platform using the graphical user interface (GUI) installation as described in Chapter 5, Installing the Open Telecommunications Platform Using the Graphical User Interface. An external OTP installation server is required for this method.
The external OTP installation server is a temporary server, and is needed only for the duration of the GUI-based installation and configuration process.
If you have already installed the Open Telecommunications Platform using either of the above methods, you can install the Open Telecommunications Platform to a new standalone OTP host or new clustered OTP hosts using your existing OTP System as described in Chapter 6, Installing the Open Telecommunications Platform Using an Existing OTP System.
