5.2.4 Resources Estimation for Existing Customers
During the virtualization planning, the existing customers would usually use any of specialized capacity
planning tools (Platespin PowerRecon, VMware Capacity Planner, …) to collect performance data of their
physical servers (the usage of them is out of scope of this document) and then plan the deployment of their
virtual infrastructure. If this is not the case, the same task can be also accomplished simply by collecting
performance data for the typical workload for the particular application for a longer time (1-2 weeks) by the
Windows performance monitor. It is even possible to collect minimum requirements also if running the
particular application already in the VM. However, in this case the consumed processor utilization should be
measured via the Virtual Infrastructure client in processor bandwidth expressed in MHz.
During this process, the following most important resource requirements should be collected:
1. Processor utilization (%)
2. Memory usage
3. Disk throughput (kBytes/sec, IOPS)
4. Network throughput (kBytes/sec)
If the performance data should be collected by the Windows Performance Monitor, start it locally or on any
other Windows computer in the network (in latter case you will have to specify an appropriate user with
admin rights on the computer being monitored) and setup logging for following performance objects:
Double-check whether disk performance counters have been activated (they are not active by default) by
