Abstract

Systems, methods, and software for analyzing the layout of computer equipment racks in a datacenter. One embodiment involves obtaining the position relative to the computer room of each of a plurality of temperature sensors distributed among a plurality of computer components mounted between opposing intake and exhaust ends of each computer equipment rack. The layout of the computer equipment racks is automatically determined from the positions of the temperature sensors, and a representation of the layout of the computer equipment racks is electronically stored or displayed. The actual layout is compared to target layout parameters to score the layout.

Claims

1. A method, comprising:

identifying the position of each of a plurality of temperature sensors distributed among a plurality of computer components mounted between opposing intake and exhaust ends of two or more computer equipment racks;

determining the layout of the two or more computer equipment racks from the positions of the temperature sensors; and

electronically storing or displaying a representation of the layout of the computer equipment racks.

2. The method of claim 1, wherein the step of determining the layout comprises identifying, for each computer equipment rack, three or more intake temperature sensors defining a plane of the intake end.

3. The method of claim 2, further comprising:

randomly selecting a subset of the intake temperature sensors;

determining from the positions of the subset of intake temperature sensors whether the subset of intake temperature sensors define a vertically oriented plane; and

if the plane is determined to be vertically oriented, comparing the horizontal spacing between consecutive temperature sensors in the plane to the expected maximum spacing between temperature sensors in the intake end of a rack to determine whether the plane traverses any aisle between racks.

4. The method of claim 3, further comprising identifying the plane as a cold-aisle boundary if the plane does not traverse any aisle between racks.

5. The method of claim 1, further comprising identifying if the intake end of a first computer equipment rack faces the exhaust end of a second computer equipment rack, and generating an alert in response.

6. The method of claim 1, wherein the step of determining the layout of the computer equipment racks includes determining the footprint of each computer equipment rack.

7. The method of claim 1, wherein the step of determining the layout of the computer equipment racks includes determining the spacing between the computer equipment racks.

8. The method of claim 1, further comprising:

selecting a target cold aisle space for each computer equipment rack;

identifying a pair of adjacent racks having a shared cold aisle; and

identifying and assessing a point penalty if the target cold aisle spaces overlap or have an intervening gap.

9. The method of claim 1, further comprising:

selectively repositioning one or more of the rack-mount computer components with respect to the computer equipment racks; and

repeating the step of obtaining the positions of the temperature sensors after repositioning the rack-mount computer components.

10. The method of claim 1, further comprising:

comparing actual values of layout parameters to target values of the layout parameters; and

scoring the layout according to the comparison between the actual values and target values of the layout parameters.

11. A computer program product including computer usable program code embodied on a non-transitory computer usable storage medium for analyzing the layout of computer equipment racks in a computer room, the computer program product including:

computer usable program code for obtaining the position relative to the computer room of each of a plurality of temperature sensors distributed among a plurality of heat-generating computer components removably mounted between opposing intake and exhaust ends of each computer equipment rack;

computer usable program code for determining the layout of the computer equipment racks from the positions of the temperature sensors; and

computer usable program code for electronically storing or displaying a representation of the layout of the computer equipment racks.

12. The computer program product of claim 11, wherein the computer usable program code for computing the layout comprises computer usable program code for identifying for each computer equipment rack a plurality of temperature sensors defining a plane of the intake end.

13. The computer program product of claim 12, further comprising:

computer usable program code for randomly selecting a subset of the intake temperature sensors without regard to which rack each intake temperature sensor is positioned in;

computer usable program code for determining from the positions of the subset of intake temperature sensors whether the subset of intake temperature sensors define a vertically oriented plane; and

computer usable program code for comparing the horizontal spacing between consecutive temperature sensors in the plane to the expected range of spacing between temperature sensors in the intake end of a rack to determine whether the plane is an intake plane.

14. The computer program product of claim 13, further comprising computer usable program code for identifying the exhaust plane relative to the intake plane.

15. The computer program product of claim 11, further comprising computer usable program code for identifying if the intake end of a first computer equipment rack faces the exhaust end of a second computer equipment rack, and generating an alert in response.

16. The computer program product of claim 11, wherein the step of computing the layout of the computer equipment racks includes determining the footprint of each computer equipment rack.

17. The computer program product of claim 11, wherein the computer usable program code for computing the layout of the computer equipment racks includes computer usable program code for determining the spacing between the computer equipment racks.

18. The computer program product of claim 11, further comprising:

computer usable program code for selecting a target cold aisle space for each computer equipment rack;

computer usable program code for identifying a pair of adjacent racks having a shared cold aisle; and

computer usable program code for identifying and assessing a point penalty if the target cold aisle spaces overlap or have an intervening gap.

19. The computer program product of claim 11, further comprising:

computer usable program code for selectively repositioning one or more of the rack-mount computer components with respect to the computer equipment racks; and

computer usable program code for repeating the step of obtaining the positions of the temperature sensors after repositioning the rack-mount computer components.

20. The computer program product of claim 11, further comprising:

computer usable program code for comparing actual values of layout parameters to target values of the layout parameters; and

computer usable program code for scoring the layout according to the comparison between the actual values and target values of the layout parameters.
