Capacity Advisor lets you test configuration changes
before actually making them in your data center, and helps you to
manage existing resources to improve their utilization. For example,
Capacity Advisor assists you in answering questions such as the following:
Is there room on this
system to support additional work?
Will this workload fit
on this system?
Can these servers be consolidated
as virtual machines on a single server?
What are the estimated
power costs for various system configurations?
What does a comparison
of several what-if scenarios reveal about the analyzed alternatives?
What is the historic behavior
of a system or workload?
Capacity Advisor obtains data for analysis from
the following data collectors:
HP Utilization WBEM Provider
HP OpenView Performance Agent (OVPA)
Performance Management Pack (PMP)
The Capacity Advisor data can consist of the following
system resources:
CPU cores (number) and speed
Memory
Network I/O bandwidth
Disk I/O bandwidth
Power usage
Capacity Advisor enables you to collect resource
data and create visualization graphs with the following views:
Historical utilization
Data peaks
Peak durations
Forecasting trends
with the following utilization limits:
sustained time
percentage of time
Capacity Advisor enables you to create scenarios
for what-if planning and forecasting, performing tasks such as the
following:
For systems in scenarios:
Create systems
Remove systems
Edit system attributes
Move virtual machines
For workloads in scenarios:
Create workloads
Collect utilization data
for workloads
Import existing workload
profiles
Edit workload demands
Move workloads between
systems
Park workloads
Delete workloads
For scenarios themselves:
View and undo/redo scenario changes
Use the HP Smart Solver technology to perform:
Automated server consolidation to virtual machines
Automated load balancing of existing VM hosts or existing servers
