This is the process for wim image capture and deploy, an alternative method of deployment can be used with the KACE Streaming WIM Toolkit (http://www.itninja.com/blog/view/kace-streaming-wim-toolkit-kswim)
Deployment is executed via task engine and has the ability to multicast single partition WIM image deployments.
When capturing a WIM image, it follows this process:
First, disk usage is calculated for the partition(s) being captured.
The capture process will require at least one partition to have enough free space on it to hold the contents of largest partition, uncompressed. This means if you are using 30gb of disk space, you will need 30gb of contiguous free space on one of the partitions on the system.
A temporary directory is then created and the data is then captured to a WIM image in that folder.
Finally, the WIM image is transferred to the K2000.
Note: If there is not enough space for capture, you can connect a external disk with enough free space for it to continue with the capture process.
When deploying a WIM image, it follows this process:
First, available disk space is checked across all local disks on the target system.
If not enough space is found for just the uncompressed image, it will fail to deploy.
If there's enough space for the uncompressed image but not for the compressed image, it will stream the image from the K2000. Please note that you cannot stream a multicast image, there must be enough space for the uncompressed and compressed image files.
