HP Capacity Advisor 7.1 User Guide
Abstract
This guide describes how Capacity Advisor can help you plan for resource usage changes in a virtualized server environment,
and analyze system data to flag any potential problems. Examples help you with common planning and analysis tasks. This
document is for technical professionals working in data center operations, administration, and planning. Some understanding
of system administration is assumed.
