This section provides a high level overview of the tasks and responsibilities of a system administrator for the Red Hat Storage Console platform. The tasks are divided into two general groups:
- Configuring a new logical cluster is the most important task of the system administrator. Designing a new cluster requires an understanding of capacity planning and definition of requirements. Typically this is determined by the solution architect, who provides the requirement to the system architect. Preparing to set up the storage environment is a significant part of the set up, and is usually part of the system administrator's role.
- Maintaining the cluster, including performing updates and monitoring usage and performance to keep the cluster responsive to changing needs and loads.
The procedures to complete these tasks are described in detail in later sections of this guide.
It is assumed that you have already read the material in Red Hat Storage Console 2.0 Installation Guide.
This section describes how to maintain a Red Hat Storage Console platform.
The administrator's tasks include:
- Managing physical resources such as servers.
- Managing storage environment. This includes creating, deleting, expansion, and shrinking of volumes and clusters.
- Monitoring the overall system resources for potential problems such as extreme load on one of the servers, insufficient memory or disk space, and taking any necessary actions.
- Managing user setup and access and setting user and administrator permission levels. This includes assigning or customizing roles to suit the needs of the enterprise.
- Troubleshooting for specific users or servers or overall system functionality.
These tasks are described in detail in later sections of this guide.
