A method of creating a root-of-trust (RoT) within a network fabric may include powering on a network interface card (NIC) baseboard management controller (BMC) (NIC BMC), booting up a NIC via the NIC BMC, obtaining an address for the NIC, verifying an identity of the NIC at a fabric trust identity server using a key obtained from a secure vault communicatively coupled to the NIC BMC, verifying with the fabric trust identity server a number of images of a host device residing in the NIC based at least in part on the identity of the NIC being verified, and instructing a platform BMC to boot up the host device based at least in part on the number of images of the host device being verified.

Fabric-based root-of-trust

Providing concurrent access to a set of shared resources is disclosed. An attempt is made, at the time it becomes necessary to use each resource required to perform an operation or set of operations, to lock the resource. For each attempt to lock a required resource, information associated with the attempt to lock the resource is stored. In the event a lock cannot be obtained with respect to a required resource, a renewed attempt to perform the operation or set of operations is initiated. At the outset of the renewed attempt, an attempt is made to lock all of the required resources that were locked or attempted to be lock during the previous attempt to perform the operation or set of operations.
