1. A method performed by a communicating entity in a disaggregated data center architecture, wherein computing resources are separated in discrete resource pools and associated together to represent a functional server, the method comprising:
handling received updated cache related data using an index, wherein the index indicates an identity of a cache coherency domain, in which the index comprises a first part that identifies processor cores that are part of the cache coherency domain across the disaggregated data center architecture, a second part that identifies participating processor cores of a generating processor socket, and a third part that identifies whether a message needs to be sent out of present processor socket.
