Network IT is everywhere…the network is everywhere! ESRF operates with a class B IP address: 160.103.a.b a=subnet, b=host • • Network speed: Mbps or Gbps = Mega or Giga bits per second Network backbone based on Extreme Network switches: • BlackDiamond8k switches with multiple 10 Gbps backbone links • On the beamlines: Extreme Summit X450-48P • 398 switches, all with 1 Gbps or 10Gbps ports • Inter-switch links based on up to 8 x 10 Gbps ports • Extreme Networks = fast (10 G wires-peed routing, filtering), reliable (dual power, dual management, dual modules), stable • First 40 Gbps ports ordered ISDD Friday lecture – Computing Infrastructure Slide: 10

Computer rooms / data centres Two computer rooms – data centres CTRM – 150 kW electrical power, 110 m 2 Central Building – 370 kW electrical power, 300 m 2 Why? Never put all eggs into the same basket keep a copy of all data in the two rooms Disks tapes Split fault tolerant systems between the two rooms Many technical rooms, at least one in each building – network hubs Why a new+bigger data centre? Insufficient power Insufficient cooling Insufficient floor space Inadequate infrastructure Instant provisioning required: rack space network connections power outlets ISDD Friday lecture – Computing Infrastructure Slide: 17
Data Centre - Construction Built around the existing computing room, all equipement kept operational during the works Reinforced slab and false floor supporting 1000 kg/m 2 Fireproof glass windows Noise reduction ISDD Friday lecture – Computing Infrastructure Slide: 18
Data Centre - Construction 10 months (without preparatory works) Dust minimized Noise minimized Disturbance minimized Cooling kept efficient Computing equipment kept up and running (even when replacing the racks!) ISDD Friday lecture – Computing Infrastructure Slide: 19
Data Centre - design 300 m 2 370 kW 1000 kg/m 2 Cold aisle / hot aisle Low density area = 66 racks, 170 kW High density area = 10 racks, 200 kW ISDD Friday lecture – Computing Infrastructure Slide: 20
Data Centre – behind the scene Dual power supply for all equipment Dual UPS in separate rooms Aerial cable trays for electricity + network Flexible and modular electrical distribution Dual cooling system = chilled water + air exchangers Smoke extraction system (in case of fire) Chilled water circuit for the high density area False floor: several fan-equipped tiles ISDD Friday lecture – Computing Infrastructure Slide: 21
Data Centre – cooling Cold aisle / Hot aisle principle – section view Extract hot air Rack Computer Inject cold air in false floor ISDD Friday lecture – Computing Infrastructure Slide: 22
Data Centre – cooling Cold aisle / Hot aisle principle – aerial view ISDD Friday lecture – Computing Infrastructure Slide: 23
Why a high density area? Top view Rack A perforated tile is not sufficient for cooling a single rack full of powerful servers (20-30 kW/rack), free air flow 6 dedicated typically allows for 10-15 kW/rack AC units maximum More efficient : cold air has not to be pushed over 20 meters to the computers Computer More reliable : one of the 6 units can fail without consequence Door Slide: 24 ISDD Friday lecture – Computing Infrastructure
Data Centre “The cube” (closed hot aisle, up to 200 kW) Two rows of racks (cold aisle) ISDD Friday lecture – Computing Infrastructure Slide: 25
