• 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

• 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)

• 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

Need to Know: Networks and Access
