The resource status when the virtual machine is moved from another host to the host of the over committing operation by using Systemwalker Service Quality Coordinator can be simulated beforehand. The virtual machine is moved based on this simulation result, and an empty host is secured.
Here, it explains the procedure of the simulation that uses the scenario of the VMware virtual machine relocation category.
Point
Relocation can be examined about a virtual host in the same system group by the following procedures.
Grasp of current state
The VMware rsc. usage cond.(List of host) report of the VMware virtual machine relocation category is selected with Analysis/Planning window, the analytical condition is set, and the report is displayed.
Please refer to "4.3 How to Operate the Analysis/Planning Window" for the setting method of the analytical condition.
The resource quota and the amount of the resource use of each virtual host are displayed by the list.
For instance, it sorts with CPU usage rate and Memory usage rate, and the host that there is becoming empty in the resource is confirmed. The movement origin and, next, the host with a low percentage utilisation is examined as a moving destination with the host with the lowest percentage utilisation.
Please confirm whether the throughput of the disk and the Network is large about the host who assumes the examination object as a movement former reaching moving destination.
Examination of relocation
The VMware rsc. usage cond.(Virtual machine stack) report of the VMware virtual machine relocation category is selected with Analysis/Planning window, the analytical condition is set, and the report is displayed.
Please refer to "4.3 How to Operate the Analysis/Planning Window" for the setting method of the analytical condition.
Resource use information on the virtual machine among virtual hosts is displayed in the piling graph.
The amount of the resource use of each virtual machine is confirmed, and which virtual machine is moved to which moving destination candidate's host is examined.
Relocation simulation
The VMware virtual machine relocation simulation report of the VMware virtual machine relocation category is selected with Analysis/Planning window, and the analytical condition is set and simulated.
Please refer to "4.3 How to Operate the Analysis/Planning Window" for the setting method of the analytical condition.
Simulation method: Each time zone
Simulation method: Time series
Simulation method: Each day of the week
Information on consolidated virtual machine and all virtual machines among hosts consolidating ahead is displayed in the piling graph. The table is additionally displayed as the above-mentioned graph.
The combination of relocated virtual machines is examined when there is bias by the value too large, and time zone and day of the week, etc. about each resource through the period.
When the threshold is set, whether the value is greatly exceeded is confirmed.
