A replacement node replaces a failed node and a baseboard management controller (BMC) for the replacement node generates a nonce code that is accessible to an authenticated user. An edge management node receives the nonce code from the user and sends a maintenance token to a BMC of a peer node in an edge cluster, wherein the peer nodes BMCs within the cluster are in a BMC federation that included the failed node BMC and have access to a BMC configuration for the failed node. The management node sends the token and the nonce code to the replacement node BMC for authentication of the token. The peer node BMC sends the token received from the management node to the replacement node BMC for authentication of the peer node BMC. The authenticated peer node BMC may then deploy the BMC configuration to the replacement node BMC.

An apparatus, such as a computing node, includes a storage device for storing program instructions and a service processor for processing the program instructions to: send an out-of-band request for access to an operator panel, wherein the out-of-band request is sent over a local network domain operatively coupling a plurality of computing nodes; receive a first out-of-band reply identifying an address and one or more capabilities of an operator panel accessible over the local network domain; and negotiate an active link to the operator panel over the local network domain. Another apparatus is similar but further includes an operator panel operatively coupled to a service processor, the service processor for processing the program instructions to: receive the out-of-band request over the local network domain; send the first out-of-band message; and negotiate an active link between the operator panel and a computing node.

A method for an intelligent multi-path call home includes detecting, at a BMC, an error in a computing device managed by the BMC and sending a call home message to a management server. The computing device is one of a plurality of computing devices each with a BMC in communication with the management server. The management server is programmed to relay the call home message to a call home destination remote from the computing devices and management server. The method includes determining that the management server failed to receive the call home message and/or failed to successfully relay the call home message to the call home destination, and transmitting, from the BMC, the call home message to the call home destination in response to determining that the management server failed to receive the call home message and/or failed to successfully relay the call home message to the call home destination.

Transparent memory management for over-subscribed accelerators is disclosed. A request from a remote initiator to execute a workload on a shared accelerator is received at a host system comprising the shared accelerator. A determination is made that there is insufficient physical memory of the accelerator to accommodate the request from the remote initiator. Responsive to determining that there is insufficient physical memory of the accelerator. An allocation of host system memory is requested for the remote initiator from the host system. A mapping between the remote initiator and the allocation of host system memory is then created.

A method for an intelligent multicast proxy between containers and an outside network includes receiving, at a proxy, a multicast discovery message from a container of one or more containers running on a host OS of a server. The proxy is running on the host OS and the server is connected to computing devices over a subnet network. The method includes adding a container tag to a user defined field of the multicast discovery message and relaying the multicast discovery message with the container tag to two or more of the computing devices connected to the subnet network. The method includes receiving a response to the multicast discovery message, where the response includes the container tag, and relaying the response to the container based on the container tag.
