Solaris Resource Manager 1.3 System Administration Guide

Server Consolidation

Solaris Resource Manager is ideal for environments that are consolidating multiple applications on a single server. The cost and complexity of managing numerous machines encourages system managers to consolidate applications on larger, more scalable systems. With Solaris Resource Manager, it's easy to achieve these economies of scale.

As an example, a single Sun server could provide application, file, and print services for heterogeneous clients, messaging/mail service, web service, and mission-critical database applications. Since Sun EnterpriseTM servers scale from 1 to 64 processors, one server could be configured for several departments to share or for an entire enterprise to use. In other server consolidation efforts, the development, prototype, and production environments are combined on a single large machine such as the Sun Enterprise 10000 or Sun Enterprise 6500, rather than being hosted on three separate servers. Still other consolidation projects combine database and application servers within a single machine, or multiple data marts. Regardless of the application type or configuration, Solaris Resource Manager helps ensure that the system's resources are allocated among all users, applications, and groups according to the defined policy. Critical applications are protected because they are guaranteed the share of the available system resources they need.
