LDAP Server Environment centralizes management of IBM PowerHA systemmirror High Availability cluster

IBM System Director provides a dedicated management platform that consolidates operations and simplifies configuration steps to achieve centralized management.

Due to the limitation of space, this article can not elaborate on each of the concepts and terminology involved. You can find out the relevant information about the concepts appearing in the text for the specific environment. The focus of this paper is to emphasize the actual operation steps and methods.

The article will pay attention to the expression of the operation of the steps and operational results of the analysis.

Introduction to some important concepts

IBM Bae Director

IBM Bae Director is a set of platform management software. It can effectively manage physical and virtual devices and improve the efficiency of the system. IBM Bae Director provides a simple and easy-to-use way to store different http://www.aliyun.com/zixun/aggregation/11585.html "> hardware devices, including servers, SAN environments, Networks, fibre switches, and so on. It also focuses on centralized management of different operating systems and different virtual environments.

PowerHA Systemmirror

PowerHA Systemmirror is a highly available software that can be broadly understood as a high-availability solution. A high-availability solution ensures that any component of the solution fails without the user being able to use the application and its data. The main function of PowerHA Systemmirror is to allow the system to cope with failures and reduce application downtime.

LDAP

English full Name: Lightweight Directory Access Kyoto (Lightweight Directory Access Protocol). LDAP primarily implements the type of information service required by an operating system and application on a common platform architecture that can be received and implemented by many platforms and applications. The information model uses concepts and patterns such as items, object classes, attributes, and so on to describe the information. In terms of namespaces, both the directory information tree structure and the hierarchical naming model are used. On the functional model, similar operations commands are used to manage directory information. In the framework of authentication, the user name and password can be implemented, or the authentication mechanism based on secure encryption method is realized. LDAP Server can be managed by each organization, not only ensure the overall structure of directory information consistency, but also meet the needs of hierarchical management.

EFS

English full Name: Encrypting File System (encrypting filesystem). Using EFS to encrypt files to protect confidential data is not stolen by an attacker who accesses the computer directly.

Description of the experimental environment

Figure 1. Topological diagram of experimental environment

As you can see from Figure 1, the lab environment is made up of a high-availability cluster, shared network, shared storage, Director server, and LDAP server. All nodes in the cluster are lpars on the same physical machine. Provides heartbeat resources and network resources for high-availability clusters through shared storage and shared networks. Configure the LDAP Server for the high-availability cluster according to the PowerHA systemmirror option. Use Director server to manage this entire suite of environments, including high-availability clusters and LDAP servers.
