Fabric discovery for a cluster of nodes

A system on a chip (SoC) unit intended to be used as one instance of a plurality of instances of SoC nodes arranged as a cluster of SoC nodes, comprising:

• one or more processing cores for processing information for one or more client systems;
• and
• a management engine coupled to the one or more processing cores, wherein the management engine includes one or more management processors, memory accessible by the one or more management processors, and instructions residing on the memory for being processed by the one or more management processors, wherein the instructions are configured for causing the one or more management processors to:
• determine routing information for neighbor nodes within the cluster of nodes;
• receive neighbor node routing information from other ones of the nodes;
• and
• use the neighbor routing information to generate a depth chart containing routing information for each other one of the nodes in the cluster.

A method performed by each one of a plurality of nodes of a cluster of nodes for generating routing information to each other one of the nodes of the cluster, comprising:

• one or more management processors of a particular one of the nodes of the cluster accessing, from memory allocated to the one or more management processors of the particular one of the nodes, instructions causing the one or more management processors to generate a neighbor depth chart thereof;
• the one or more management processors of the particular one of the nodes accessing, from the memory allocated thereto, instructions causing the one or more management processors of the particular one of the nodes to propagate entries of the node depth chart thereof for reception by neighbors of the particular one of the nodes;
• and
• the one or more management processors of the particular one of the nodes accessing, from the memory allocated thereto, instructions causing the one or more management processors of the particular one of the nodes to create a cluster depth chart for each one of the nodes using the node depth chart entries received thereby, wherein the cluster depth chart is an aggregation of the node depth chart entries for the particular one of the nodes and depth chart entries received by the particular one of the nodes from other ones of the nodes.

A non-transitory computer-readable medium having tangibly embodied thereon and accessible therefrom a set of instructions interpretable by one or more data processing devices, the set of instructions is configured for causing the one or more data processing devices to implement operations for:

• generating a neighbor depth chart thereof;
• propagating entries of the node depth chart thereof for reception by neighbors of the particular one of the nodes;
• and
• creating a cluster depth chart for each one of the nodes using the node depth chart entries received thereby, wherein the cluster depth chart is an aggregation of the node depth chart entries for the particular one of the nodes and depth chart entries received by the particular one of the nodes from other ones of the nodes.
