3.9. Server consolidation
Requirement
[ug] In a data center, several applications run whose workload is too low (often much less than 50%).
The computers themselves usually require a lot of electricity, cooling and space.
Solution
[ug] Several applications are consolidated in zones on one computer. The details:
• This can usually be done with sparse root zones.
• Install exactly one application per zone.
• Option: Software installation by shared directory .
• Option: Automatic software installation.
• Option: Resource management with resource pools.
• Option: Resource management with fair share scheduler.
• Option: Network resource management with IPQoS.
• Option: High availability by the use of a cluster.
• Option: Software installation per provisioning
Assessment
[ug] This use case has the following characteristics:
• The operating division's costs are lower since less space, energy and cooling are required.
• The application department has the same encapsulation of the application and precisely defined
interfaces. The availability of the application increases.
