Composable Fabric Manager ( CFM ) Software Suite

---

Overview

The CFM Software Suite provides a client interface for interacting with a Composable Memory Appliance (CMA). The software suite consists of a few components.

• cfm-service is a Go language Linux service running in the background. It contains the main business logic for managing CMA memory. It provides a north-side (frontend) OpenAPI interface for client(s) and a south-side (backend) Redfish interface to manage available Composable Memory Appliances (CMAs) and CXL Hosts.
• cfm-cli is a Go language interactive program providing cfm-service command line functionality to a single user. This will interact with the north-side (frontend) OpenAPI interface provided by cfm-service. It is intended to free the users of needing to use curl commands to directly interact with cfm-service's OpenAPI interface.
• cfm-webui is a single-page application presenting a web UI using Vue.js 3. This will interact with the north-side (frontend) OpenAPI interface provided by cfm-service. This application is generally auto launched by cfm-service.
• cxl-host is a linux service that runs directly on the cxl-host server. This will interact with the south-side (backend) Redfish interface of the cfm-service.

Quick Start

Setup

Docker

• The standard CFM release package runs within a docker container.
• To install docker, one can follow the steps from docker.docs
  • Example: Install Docker Engine on Ubuntu | Docker Docs

NOTE: If uncertain of which install option to use, the “install using the apt repository” option is a suggested option.

Installation\Operation

• DOCKER - Information on running the CFM Software Suite from within a Docker container

Build locally

• User must run 'make generate' to generate all supporting files from the api yaml before building local binaries.

Additional Project Documentation

• README-SERVICE - README file for the cfm-service component
• README-WEBUI - README file for the cfm-webui component
• README-CLI - README file for the cfm-cli component
• SETUP - Information on setting up a development environment
• LOG - Information on logging level definations
• TEMPLATES - Information on the template file used in openapi-generate for generating the go service

Known Issues

Here is a list of known issues that will be fixed in a future release:

• CFM\Hardware Re-synchronization
  • Currently, if a registered CMA blade is power-cycled, the cfm-service has no way to automatically detect this action.
  • A resync webui button (and cli cmd) have been provided to give the user manual control to force the service to update itself against the hardware (since it is assumed that the user is aware of the power cycle action).
• During startup, possible CFM response delay (via the WebUI\CLI tool)
  • During cfm-service initialization, it re-register(s) with previously registered CMA and CXL-Host hardware.
  • This can take some time, depending on how many devices are involved.
    • A single blade takes ~5-10 sec to register\connect.
  • There is currently no user feedback while this action is occurring (other than checking the docker service logs, docker logs <container_name>, in real time), so the user will need to wait before attempting any actions via the WebUI or CLI tools.
  • For the WebUI, use the browser's refresh button when attempting to see if this service inialization is complete.
