Tuning performance for Windows Server 2012 or 2012 R2 Standard virtual images
Tuning the performance of a Windows Server 2012 or a 2012 R2 Standard virtual image can improve deployment times for your virtual patterns.
About this task
The following recommended tuning tips can help improve the performance of a Windows Server 2012 or 2012 R2 Standard virtual image. You can apply these
performance improvements to the virtual image by using the virtual image extend and capture function
in the console.
Note: These recommendations are
based on the image tested by IBM®. Some of these
recommendations might not apply to the image used in your environment.
To apply
these performance improvements to your virtual image, you typically
complete the following general procedure:
- Create the virtual image using Windows OS pattern kit.
- Import the virtual image into the PureApplication® System catalog of virtual images by using the console.
- Extend the imported virtual image. As part of this process, the virtual image is included in a virtual system pattern, which is then deployed. The virtual machine is started as part of the virtual system pattern deployment. As it is started for the first time, the virtual machine adapts to the PureApplication System environment.
- Make the recommended tuning modifications to the deployed virtual machine as described below.
- Capture the modified extended image back. The new captured image includes the adaptations along with the tuning modifications.
Even if you decide not to make these recommended tuning modifications to the virtual image that you create using the OS pattern kit, you should still extend and capture the imported image as described in the above procedure. Use the extended and captured virtual image in new virtual system patterns, instead of the original image. This new image will have the PureApplication System adaptations. Using that image results in shorter deployment times.
