An IPMI-Based Slow Control System for the PANDA Compute Node* — Martin Galuska, •Thomas Geßler, Wolfgang Kühn, Johannes Lang, Jens Sören Lange, Yutie Liang, Ming Liu, Björn Spruck, and Qiang Wang — II. Physikalisches Institut, Justus-Liebig-Universität Gießen

Reaction rate of 10–20 MHz from antiproton-proton-collisions are expected for the PANDA experiment at FAIR, leading to a raw data output rate of up to 200 GB/s. A sophisticated data acquisition system is needed in order to select physically relevant events online. A network of FPGA-based Compute Nodes will be used for this purpose.

An AdvancedTCA shelf provides the infrastructure for up to 14 Compute Nodes. A Shelf Manager supervises the system health and regulates power distribution and temperature. It relies on a local controller on each Compute Node to relay sensor readings, provide power requirements etc. This makes remote management of the entire system possible. An IPM Controller based on an Atmel microcontroller was designed for this purpose, and a prototype was produced.

The necessary firmware is being developed to allow interaction with the components of the Compute Node and the Shelf Manager conform to the AdvancedTCA specification. A set of basic mandatory functions was implemented that can be extended easily. An improved version of the controller is in development. An overview of the intended functions of the controller and a status report will be given.
