Abstract: Techniques for sending Compute Express Link (CXL) packets over Ethernet (CXL-E) in a composable data center that may include disaggregated, composable servers. The techniques may include receiving, from a first server device, a request to bind the first server device with a multiple logical device (MLD) appliance. Based at least in part on the request, a first CXL-E connection may be established for the first server device to export a computing resource to the MLD appliance. The techniques may also include receiving, from the MLD appliance, an indication that the computing resource is available, and receiving, from a second server device, a second request for the computing resource. Based at least in part on the second request, a second CXL-E connection may be established for the second server device to consume or otherwise utilize the computing resource of the first server device via the MLD appliance.

Abstract: A system and method of securing and virtualizing firmware trusted platform modules (TPMs) for virtualizing a hardware security module (HSM) for a host within a network fabric is provided. The system and method include operably coupling a set of components associated with a host comprising a data processing unit (DPU) secure vault and a firmware trusted platform module (TPM). The firmware TPM is configured as a virtual firmware TPM. The DPU secure vault secures the virtual firmware TPM into one or more virtual firmware TPMs based on one or more partitions configured with the DPU secure vault. A virtual TPM manager communicatively coupled to the DPU secure vault manages one or more virtual TPMs for hosting a set of Virtual Machines (VMs) or Containers.

Abstract: 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.
