What is RedFish
Open industry standard specification, API and schema developed by DMTF.
Build new interface RESTful/JSON style to replace old IPMI or CLI approach.
Publish an open industry standard specification and schema that meets the expectations of end users for simple, modern and secure management of scalable platform hardware.
Define for servers.

What is RedFish
Redfish has two kinds of versioning
The version of the protocol
/redfish/v1/
The version of the resource schema
Main Object
Systems
Anything accessed in the data plane from the CPU is represented as a system
Managers
Managers represent your BMC, Enclosure Manager or other component that is managing the infrastructure.
Chassis
Represents the physical aspects and containment of the infrastructure. Racks, enclosures.

6. Accton’s RedFish Service
Assumptions
Support is required for 1RU chassis only
support only HTTPS
Use management interface for communication.

7. Accton’s RedFish Service
Redfish service running in Edge-core asfvolt16 OLT will be based on REST query to access asfvolt16 hardware components. It supports health monitoring of hardware components.
HEALTH MONITORING
Provide FANs/PSU/Temperature/SFP port present/
OLT reboot/shutdown.
GracefulRestart.
ForceRestart.
GracefulShutdown.
ForceOff.
Other API

8. Accton’s RedFish Service
Customized implementation of Intel Rack Scale Design.
C++ implementation.
Rack Scale Design is designed for data center rack usage.
From Intel RSD v (latest one is 2.3.1)
Redfish version is “1.0.2”
Use its PSME-chassis/network modules.
Includes two applications
usr/local/bin/psme-rest-server /etc/psme/psme.conf
/usr/local/bin/psme-chassis /etc/psme/platform_info.conf

9. Accton’s RedFish Service
psme-rest-server
Use system port 8888.
handles GET/POST requests and response with clients.
psme-chassis
Regisity to psme-rest-server on port 8383
Internally use script for accessing OLT hardware modules via /sys interface.
Fetches health data of OLT chassis modules periodically and updates psme- rest-server with current chassis health data through json-rpc call.

16. RESTful client
RESTful client is python program which will communicate with redfish server on the specified IP/port (8888).
RESTful client will also build on a RESTful architecture and perform get/set functions, required for management and configuration of asfvOLT16 (Broadcom) OLT through REST APIs.

17. RESTful client Demo
Use ELK (Elasticsearch/heartbeat, Logstash, Kibana) , Restful Client to do PM.
