The N1 Image Server (N1 IS) is used to store operating system disk images for each type of server blade in a chassis, and to load the disk images to server blades using the JumpStartTM and Flash archives depending on the type of server blade and operating system. The image server is typically installed on the control plane server. If desired, the image server can be installed on a separate machine.
For best results, use a Gigabit copper Network Interface Card (NIC) for the image server.
