Fabric Resource Orchestrator with Bidirectional Requester and Responder Capabilities for Scalable CXL Fabrics

An apparatus comprising:

• a first interface configured to communicate with a Fabric Resource Entity (FRE) based on CXL.io, wherein CXL denotes Compute Express Link, and wherein the FRE comprises resources accessible by hosts or peer devices within a CXL Fabric and is configured to initiate CXL.io requests to access remote resources;
• a second interface configured to communicate with a target entity based on a second protocol;
• and
• a computer coupled to the first interface and the second interface, the computer configured to:
• receive, from the FRE via the first interface, a CXL.io request comprising a first address;
• translate the CXL.io request to a request conforming to the second protocol and comprising a second address;
• send, via the second interface, the request conforming to the second protocol to the target entity;
• receive, via the second interface, a response conforming to the second protocol from the target entity;
• translate the response conforming to the second protocol to a CXL.io completion;
• and
• send, via the first interface, the CXL.io completion to the FRE.

A system comprising:

• a Fabric Resource Entity (FRE) coupled to a Compute Express Link (CXL) Fabric, wherein the FRE is configured to receive memory access requests from hosts or peer devices and to initiate CXL.io requests as a requester within the CXL Fabric;
• a target entity;
• and
• a computer coupled between the FRE and the target entity, the computer configured to:
• receive, from the FRE, a CXL.io request comprising a first address;
• translate the CXL.io request to a request conforming to a second protocol utilized by the target entity, wherein the request conforming to the second protocol comprises a second address;
• send, to the target entity, the request conforming to the second protocol;
• receive, from the target entity, a response conforming to the second protocol;
• translate the response conforming to the second protocol to a CXL.io completion;
• and
• send, to the FRE, the CXL.io completion.
