Disk space requirements
Plan to allot the following amounts of memory for each
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.
For additional information on disk space requirements, see the Matrix Operating Environment
installation guide appropriate for your operating system at
.
Credentials
To use Capacity Advisor, to collect data, and to run reports, you must have credentials (a valid
user name and password) and appropriate toolbox authorization on systems where you plan to
use Capacity Advisor. For specifics about setting up user authorizations, see the “User
Authorizations” topic in the Matrix Operating Environment help.
TIP:
For access to Matrix Operating Environment help from Capacity Advisor Help, click the
“Overview” topic in the left navigation, and then click “Matrix Operating Environment help.”
Dependencies
Data collection requires that credentials for each managed server be configured in HP Systems
Insight Manager.
•
WBEM/WMI credentials must be configured for all Windows servers, and HP-UX servers. For
agentless data collection on Windows systems, the WBEM/WMI credentials must be set to
Administrator level. WBEM certificate authentication is supported for HP-UX servers.
•
SSH credentials (user-based, host-based key, or by certificate) must be configured for all Linux
servers. Linux agentless data collection does not require root-level access. Systems Insight
Manager privilege elevation is supported on HP-UX and Linux servers using a single user
account with sudo or powerbroker with no password required.
•
The Windows or Linux managed node can be configured for agentless data collection by
running the managed system setup wizard. Administrator or root level permission on the CMS
is required to configure agentless collection on the CMS.
•
Insight Control virtual machine management is required to collect data from ProLiant/x86-based
hypervisors and their VMs and for Hyper-V VMs.
Upgrades and reinstallation
When upgrading or reinstalling software used with Capacity Advisor, there are different
considerations and procedures to follow specific to the operating systems underlying the CMS or
running on the managed node. Refer to the appropriate installation guide for instructions. Install
