  1. ATCA for ATLAS - status • Activities of the working group • PH/ESE xTCA evaluation project • Next steps

  2. ATCA working group • Mandate: • Propose a standard for modular electronics to replace VMEbus • Make recommendations with respect to best practices and common components • 18 members. Composition: • Sub-detectors • TDAQ • Sysadmins • DCS • Electronics coordinator • First meeting: Spring 2012 • 1 day workshop in July 2012 • https://indico.cern.ch/conferenceDisplay.py?confId=196590 • Recommendation document • https://edms.cern.ch/document/1304001/1

  5. (Main) ATCA recommendations (2)

  6. PH/ESE evaluation project • Started in 2011 with MTCA • ATCA recently added • Main focus is on components of general interest: • Card cages • Cooling units • Power supplies • Status • Evaluating shelves from Schroff and ASIS with focus on cooling • Have seen differences in cooling performance • Due to properties of “power groups” some slots in a shelf don’t offer the advertised power • AC/DC PSUs: • Looking at different powering schemes (per shelf, per rack, per system) • Evaluating products of: Emerson, PowerOne and Lineage • Establishing contact with additional companies (Comtel) • Commercial S/W for IPMI compliancy test available • Designers of blades are invited to test their modules in our lab • Additional information: • xTCA IG: https://espace.cern.ch/ph-dep-ese-be-PS-Evaluation/SitePages/Home.aspx • TWEPP: https://indico.cern.ch/sessionDisplay.py?sessionId=23&confId=228972#20130926

  7. Next steps • Has the “ATCA for ATLAS” working group done its job? • Recommendations for main features made • Anyone unhappy with them? • Does anyone feel that important issues have not yet been addressed? • Should the mandate be extended to include e.g. • More detailed technical requirements • Involvement in equipment procurement • Liaising with other experts • users of ATCA (LHCb) • CERN PH/ESE xTCA evaluation team • Etc. • Is there a need for a more technical forum? • For engineers to discuss implementation details • To share knowledge and technical solutions • To perform evaluations of commercial components • The group will have to decide how and by whom this follow-up work is to be done • Visit our new Web site: https://twiki.cern.ch/twiki/bin/viewauth/Atlas/ATCAforATLAS
