If you set up more than one NetInstall server on your network, you can place copies of a specific NetBoot image on multiple servers to distribute the load. By assigning the copies the same image index ID in the range 4096–65535, you can advertise them to your clients as a single image to avoid confusion.
Note: You must customize the image by creating a workflow with the Create Image action to assign the image an index ID.
Locate the image file on the server where the original image is stored.
If the image index ID is 4095 or lower, re-create the image and modify the index ID using the Create Image action in a workflow, then assign the image an index ID in the range 4096–65535.
For more information, see System Image Utility Help.
The image ID can be changed in the Server app by double-clicking the Image and editing the image index.
Create copies or move image files to other servers.
On each server, use the Server app to enable the image for NetInstall service.
Clients still see the image listed only once in Startup Disk preferences, but the server that delivers its copy of the image is selected based on server activity.
Smaller improvements can be achieved by distributing NetBoot images across multiple disk drives on a single server.
