Abstract: The present disclosure is directed to reducing the secure boot time of software images and includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause one or more components to perform operations including identifying a software image for a first secure boot, the software image stored in a persistent storage and comprising a kickstart software package and a system software package, fetching the software image, including the kickstart software package and the system software package, from the persistent storage to a memory, verifying one or more digital signatures associated with the software image, booting the kickstart software package of the software image from the memory, and staging the system software package in the persistent storage.

Abstract: An apparatus controls discovery of nodes for a network fabric and accommodates communication among the nodes. The apparatus may be a controller operating as a first node on a network and having a processor connected to memory. The controller is communicatively connected to a second node that has a native network protocol. The memory stores computer readable software instructions that, when implemented by the processor, cause the controller to send a discovery data packet to the second node in the second node's native network protocol. The discovery data packet advertises controller status information to the second node for use in establishing a communications link between the controller and the second node in the network fabric.
