Description

• Modeled testbed included server room equipped with two heterogeneously occupied racks (with each server modeled separately) and one roof-mounted cooling device.
• Setup was examined virtually for 3 servers power usage scenarios and also 3 air conditioning temperature scenarios.
• Each rack has 8 and 6 active devices respectively.
• The dataset is every second measurement of temperature in 4 virtual probes, inlet/outlet of each server and air conditioner.
• Detailed numerics of the server room can be found in link mentioned above.
• Brief diagram of server room (red: rack 1, blue: rack 2, dots: virtual probes)

Data Statistics

Overview

• # of 1st scenarios (air conditioning temperature setup) : 3
• # of 2nd scenarios (power usage variation) : 3
• # of temperature probes : 34
• # of measuring time (every 1s) : 4157

Mode

• ServerRoomCFD.tensor: 4
  • Mode 1 : air conditioning temperature setups (24, 27 and 30 Celsius degrees)
  • Mode 2 : power usage (50%/75%/100% scenario)
  • Mode 3 : temperature probes
  • Mode 4 : duration time (3000~4000s)

Index of <Probe>	Probe Location
1~2	Inlet/Outlet of air conditioner
3~6	Virtual probe located in (1.8, 2.12, 1.42), (4.8, 1.65, 1.5), (2.5, 2.09, 0.95), (2.8, 0.65, 0.75) (in the same order as the website)
7~22	Inlet/Outlet surfaces (odd/even indices) of each server in rack 1
23~34	Inlet/Outlet surfaces (odd/even indices) of each server in rack 2
