outline context motivations IPMI developments test board developments dec 15, 2011IPMI developments at LAPP, L.Fournier2

context evolving demand concerning performances and versatility in physics instrumentation (dataflow up to 1.4Tbits/s per board) even more complex electronics, firmware, and software growing need for easier and faster upgrades either for electronics, firmware, and software ATCA is a promising standard with multiple high speed commuted serial links dec 15, 2011IPMI developments at LAPP, L.Fournier3

motivations master ATCA standards have the best knowledge of the technologies we use long-term development with evolving components standardization of board management -> IPMI dec 15, 2011IPMI developments at LAPP, L.Fournier4

IPMI developments our needs :  complete ATCA hardware management power supplies hot swap diagnostics firmware upgrade sensor reading...  + JTAG access for debugging  + board configuration through ethernet FPGA firmware upload coefficient upload for signal processing experiment monitoring/slow control dec 15, 2011IPMI developments at LAPP, L.Fournier5

IPMI developments our IPMI solution – low cost microcontroller with a small FPGA – open source software (coreIPM), IPMI 1.5 compliant with relevant subset of IPMI 2.0 – CMT + GNU development tools originally implemented for an AMC already extended to a standard ATCA board – heavily tested and compliance with PICMG 3.0 Revision 3.0 checked with a commercial shelf manager – software structure and core components remain the same dec 15, 2011IPMI developments at LAPP, L.Fournier6

generic ATCA carrier board PICMG AMC.0 implementation more compact electronics design IPMI separated from board slow control dec 15, 2011IPMI developments at LAPP, L.Fournier11 courtesy : J-P. Cachemiche, CPPM Carrier IPM Controller Carrier IPM Controller

summary IPMI spec is a huge quantity of information but is not that complicated to implement IPMI software is totally independent from slow control the core code is portable and easily tunable code is extensively tested for robustness a more compact version of the IPM Controller is being designed for common developments for LHCb with the CPPM dec 15, 2011IPMI developments at LAPP, L.Fournier12
