Setup considerations
To prepare to use Capacity Advisor, consider the following:
• Licensing requirements
• Installation
• Upgrade and reinstallation
• Credentials
• Dependencies
Licensing requirements
Capacity Advisor is installed when HP Insight Dynamics suite is installed. For specific information
about trial and LTU (License To Use) licensing on supported platforms, see the HP Insight Dynamics
6.2 Getting Started Guide at http://www.hp.com/go/insightdynamics/docs. For added information
on using the HP Insight Capacity Advisor Consolidation software license, see “Data collection
and the HP Insight Capacity Advisor Consolidation software” (page 63). Capacity Advisor and
Capacity Advisor Consolidation Software licenses cannot be used on the same system at the
same time.
Installation
Capacity Advisor is installed with other Insight Dynamics components, so no separate installation
is required. (See the Insight Dynamics installation guide at http://www.hp.com/go/
insightdynamics/docs appropriate for your operating system.) To use Capacity Advisor, you
must have a valid license.
Collection methods
On installation of HP Insight Dynamics suite, the Insight managed system setup wizard
automatically configures the mechanism used to collect data from managed servers based on
the type of operating system that the managed system is running. (See “Supported collection
configurations” (page 17).)
Some problems with data collection can be diagnosed with vseassist. See the HP Insight
Dynamics 6.2 Getting Started Guide for additional information.
Disk space requirements
Plan to allot the following amounts of memory for each workload to collect and preserve a
maximum of four years of data for use by Capacity Advisor:
• On a Microsoft Windows CMS: Allot 64.5 MB for each workload on each Windows or Linux
managed node to support agentless data collection. Allot 34.7 MB for each workload on
each HP-UX managed node.
• On an HP-UX CMS: Allot 93.1 MB for each workload on each Integrity Linux managed
node to support agentless data collection. Allot 34.7 MB for each workload on each Integrity
Windows or HP-UX managed node.
