You can use the Performance Manager
component of Multiple Device Manager (MDM) to manage and monitor the performance
of the storage devices that MDM supports.
Performance Manager provides the following functions:
- Collecting data from devices
- Performance Manager collects data from these devices:
- IBM
TotalStorage
Enterprise
Storage Server (ESS)
- IBM TotalStorage SAN Volume Controller
- Configuring performance thresholds
- You can use the Performance Manager to set performance thresholds for
each device type. Setting thresholds for certain criteria allows Performance
Manager to notify you when a certain threshold has been crossed, thus enabling
you to take action before a critical event occurs.
- Viewing performance data from the Performance Manager database
- You can view performance data from the Performance Manager database
using the gauge application programming interfaces (APIs). These gauges present
performance data in graphical and tabular forms.
- Obtaining the current size and location of the
performance data
- You can obtain the current size and location of the performance data
of the Performance Manager database.
- Deleting performance data
- You can delete performance data from the Performance Manager database.
- Improving performance
- You can use allocation optimization algorithms to help you design your
data layout so that it meets your performance requirements for the new space.
