LSE-239 and LSE-309 Summit-Base Tiger Team Kian-Tat Lim #lsst2018 - PowerPoint PPT Presentation

LSE-239 and LSE-309 Summit-Base Tiger Team Kian-Tat Lim #lsst2018 #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 1

LSE-239 and LSE-309 - LSE-239: Base Facility Data Center Requirements - Informs design and construction - LSE-309: Summit to Base Information Technology and Communication Design - Tiger Team recommendations #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 2

Key Sections of LSE-239 - Facility (size, clearance, ducts, power, UPS, cooling, service areas) - Computing Room (seismic, raceways, cables, racks, aisles, security) - Supporting Spaces (shipping/receiving, materials prep, packing/unpacking, sysadmin office) - Logistical and Utilities (restrooms, janitorial, mechanical/electrical rooms, buried ducts, chilled water, carrier demarc) - Tier II, Tier III areas (moderate and high availability) - No tape library #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 3

Key Sections of LSE-309 - Architecture and Standards (information security, pointers to rack/facility standards, hardware/software standards, visualization, databases) - Virtualization (VMware recommended, need to add Docker) - Upgrades and Change Control (principles, no specifics yet) - Logical Model (diagrams and tables) - Physical Model (Summit and Base Facilities including power usage, Network) #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 4

Summit/Base Logical Model - Telescope Control Backbone - Camera Control Backbone - Camera Support Rooms Backbone - Operations and Management Backbone - Data Processing Backbones - Aux Backbones #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 5

Example: Aux Backbones #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 6

Need to Know: Summit Facility - Contents = Everything you would expect on the Summit - OCS, EFD, TCS, TS Control Interface, Calibration Control, Image Visualization, Atmospheric Instrument Control, Auxiliary Instruments, CCS, Camera IT, Refrigerator Compressor Controller, Camera Diagnostic Cluster, Camera Visualization, CCS-OCS Bridge, Image Data Store, Read-Out System, DAQ Management Server, Camera Annex CCS, Clean Room CCS, White Room CCS, Support Room CCS, Support Room DAQ, Summit Data Quality, Header Service, Aux DAQ, Aux CCS, Aux DAQ Management Server, Aux Diagnostic Server, Aux CCS Bridge, Aux Header Service, IPMI Diagnostics - Administration responsibility: Observatory Operations #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 7

Need to Know: Networks and Access - Control networks ("SCADA Enclave") will be isolated from the Internet and general office networks but can be on their own wireless network - Essential systems ("Observing Continuity Enclave") must be present on the Summit - Identity management will have a local replica, but changes (new accounts, group assignments) must go through NCSA - Machines will require logins under a personal account which can then be switched to a service account; remote access will require 2-factor authentication #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 8

Need to Know: Base Facility - Contents and service levels: - OCS, EFD, TCS, Camera DB Backup, Image Visualization, IPMI Diagnostics - DM systems: Archiving, Prompt Processing, Telemetry Gateway, OCS-Driven Batch, EFD Transformation, Commissioning Cluster, Data Backbone - Chilean Data Access Center - Administration responsibility: - Hardware and non-DM/DAC: Observatory Operations - Software and Configuration for DM/DAC: LSST Data Facility #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 9
