Abstract: A method, system and computer program product are provided for detecting state and sparing of optical Peripheral Component Interconnect Express (PCI-Express or PCIE) cable channels attached to an IO drawer. System firmware is provided for implementing health check functions and state detection and sparing functions. One or more optical cables are connected between a host bridge and an PCIE enclosure, each optical cable includes one or more spare optical channels. An identified failed optical channel is rerouted to the spare optical channel.

Abstract: A method, system and computer program product are provided for implementing health check for optical cable attached Peripheral Component Interconnect Express (PCIE) enclosures in a computer system. System firmware is provided for implementing health check functions. One or more optical cables are connected between a host bridge and a PCIE enclosure. A PCIE link to the PCIE enclosure is reset responsive to a predefined event. After a set delay, a PCIE link health check is performed verifying PCIE link width and speed.

Abstract: A method and computer system for implementing authentication protocol for merging multiple server nodes with trusted platform modules (TPMs) utilizing provisioned node certificates to support concurrent node add and node remove. Each of the multiple server nodes boots an instance of enablement level firmware and extended to a trusted platform module (TPM) on each node as the server nodes are powered up. A hardware secure channel is established between the server nodes for firmware message passing as part of physical configuration of the server nodes to be merged. A shared secret is securely exchanged via the hardware secure channel between the server nodes establishing an initial authentication value shared among all server nodes. All server nodes confirm common security configuration settings and exchange TPM log and platform configuration register (PCR) data to establish common history for future attestation requirements, enabling dynamic changing the server nodes and concurrently adding and removing nodes.
