2. Outline Hardware Platform Management Overview ATCA/xTCA Hardware Management Intelligent Platform Management Controller IPMC Hardware Implementation on ATCA/xTCA PCIe Carrier Summary

3. 3 Hardware Platform Management! What for? What are the motivations?

4. 4 Overview Global system management motivations Help on installation and initial plant systems setup and tests Remote system reconfiguration and monitoring Functional module operation management (application specific program selection) Remote firmware maintenance (programming and version control) Modules stock management Hardware maintenance information Hardware Platform Management

5. 5 Overview Local shelf motivations Hardware failure detection and on the fly resolution (with redundant systems and procedures) Hot insertion/removal modules possibility Temperature monitoring and fan control Power management of each module and shelf Optimization on shelf power consumption In the ATCA case, to have compatibility between modules that share ATCA shelf resources (E-Keying) Hardware Platform Management

6. 6 Architecture IPMC features and elements Compliance with IPMI specification required by PICMG® 3.0 ATCA® Base Specification messaging ATCA requires a command subset for IPMC and MMC Shelf Manager and ShMC (BMC in IPMI) I 2 C redundant (2x) bus or radial (IPMB-0) I 2 C radial (IPMB-L) to communicate with MMC in the AMC/ARTM modules in Carrier blades Field Replaceable Unit (FRU) information Sensor Data Record (SDR) descriptor Shelf-External System Manager Optional 2x radial IP capable transport ATCA/xTCA Hardware Management

7. 7 Architecture ATCA/xTCA Hardware Management

8. 8 Hardware Architecture IPMC main elements and features IPMC module (CoreIPM OPMA sodimm module) PEM for carrier payload and management power AMC/ARTM payload and management power chip IPMB-0 (A & B channels) IPMB-L isolated and controlled I 2 C bus I 2 C bus for other peripherals Ethernet on Base Interface Other IPMC mandatory peripherals (LEDs, Handle switch, Temperature sensors, WDT) JTAG functionality for AMC/ARTM, FPGA and IPMC µProc Store FRU and SDR data descriptor Intelligent Platform Management Controller

10. 10 Hardware Architecture IPMC on ATCA/xTCA PCIe Carrier

11. 11 Conclusion The IPMC implementation is almost finished in an xTCA AMC PCIe Carrier It will be implemented in other xTCA blades developed by the IPFN group Total compliance with xTCA and AMC PICMG 3.0 modules is to be achieved Software development of IPMC has already begun Taking advantages of the ATCA hardware platform management, the xTCA AMC PCIe Carrier can be used in experiences that require large, fast and distributed control systems such as the nuclear fusion experiments
