Embodiments generally relate to out-of-band management of a computing system. The present technology discloses enable a primary service controller to provide a centralized configuration of multiple secondary service controllers so that they can share a same configuration. It can utilize an authentication-free protocol to modify and manage credentials for a large number of service controllers.

Authentication-free configuration for service controllers

Embodiments generally relate to link state change detection and notification within a server with embedded or directly integrated network switch. In a server configuration in which there is no longer a distinct separation between a network switch and a network interface card (NIC), the server can no longer immediately detect a change in the link state of any of the switch's ports. This can lead to connection failure. A Link State Policy Table is thus implemented within the embedded or integrated switch, capable of changing the NIC link state according to one or more pre-defined or user-defined policy settings. The server is then notified of the change in the NIC link state, and can release an old IP address or request a new IP address accordingly.

Server link state detection and notification

Various examples of the present technology provide a method for iSCSI based bare metal OS image deployment and diskless boot in a server system. In some examples, methods for iSCSI based bare metal OS image deployment and diskless boot in a server system comprise setting a boot order of a BIOS of the server system to iSCSI NIC of a controller (e.g., BMC) of the server system, setting iSCSI boot configuration to the controller, updating the boot order based at least upon information from the controller, syncing the iSCSI boot configuration to the BIOS of the server system based upon the information from the controller, and causing the server system to be booted from a specific target IP and LUN of an iSCSI storage server of a SAN.
