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.

App	App	App	App	App
A	B	C	D	E
Resource Pool 1		Resource Pool 2
CPU1	CPU2	CPU3		CPU4
	Global Zone			CPU5
