HP Matrix Operating Environment Software - Manual (Page 82)

•
Architecture — is the workload moving from one architecture to a system with the same
architecture? If the workload may move to a system with a different architecture, what are the
implications of architectural differences?
•
Operating system — is the workload moving from one operating system to a system with the
same OS? If the workload may move to a system with a different OS, what are the implications?
•
CPU speed — is the workload moving to a system with the same or faster CPU speed?
•
CPU utilization — what is the current CPU utilization of the workload? what is the projected
growth rate of the workload
•
Available memory — is the available memory on the new system the same or greater than
that on the system where the workload currently resides?
TIP: To obtain the most meaningful feedback about the proposed move of workloads, it is
important to size the VM guest where the workload resides so that it is appropriate to the size of
the workload. This should be done prior to using the Move Workload menu option.
NOTE: When measuring CPU utilization of virtual machines, it is possible for the reported
utilization to be greater than the number of virtual CPU cores (vCPU cores) associated with the
virtual machine.
While the number of virtual machine host threads allocated to the process for the virtual machine
is restricted to the number of virtual CPU cores, the virtual machine host threads used to implement
virtual hardware, such as I/O cards, are not restricted. Under certain load conditions, this can
result in CPU utilization of more than 100% being reported for a virtual machine.
Procedure 31 To move a workload
1. If you are not on the Workload tab, click the Workload tab.
2. Click the check box preceding the workload(s) that you wish to move.
3. Select What-if Action
→Move Workloads... from the menu bar.
The Edit Scenario: Move Workloads screen displays.
4. Change the Meter Style, if desired.
5. Change the Data Range if a different size of data collection is desired, and click OK to refresh
the table display.
TIP: A longer data collection period provides a better picture of activity on the system over
time than shorter periods do.
6. Change the Meters Represent setting if a different calculation is desired .
7. The first table presents the workloads selected for the move.
8. If the original system that the workload resided on differs significantly from the intended
destination system on which you intend to run the workload, use the memory platform multiplier
to adjust for differences between the two systems. On entering a new value for the memory
platform multiplier, you must click Refresh to update the table titled Select Destination System:
with the new values.
9. Optional. Change the headroom calculation. You must click Refresh to update the server
destination table with the new values.
10. In the next table, labeled Select Destination System, take a few moments to mouse over various
entries in the table and analyze the information presented. This table lists the possible
destination systems available in this scenario, their current resource utilization information,
and their headroom rating.
