Abstract

A system includes a raised floor, a sub-floor space below the raised floor, electrical components in the sub-floor space, and a fire suppression device coupled to the raised floor. The fire suppression device dispenses fire suppression material the electrical components in the sub-floor space.

First claim

What is claimed is:

1. A data center, comprising:
a raised floor comprising one or more frame members and a plurality of tiles coupled to the one or more frame members;
one or more rack computing systems coupled to at least one of the one or more the tiles;
a sub-floor space below the raised floor;
one or more data center infrastructure components in the sub-floor space configured to supply electrical power or cooling air to computing devices in at least one of the one or more rack computing systems; and
one or more fire suppression devices mounted to at least one of the one or more tiles, wherein at least one of the one or more fire suppression devices includes a reservoir in the subfloor space and wherein the at least one of the one or more fire suppression devices is configured to dispense under pressure, from the reservoir, fire suppression material within the subfloor space to at least one of the one or more data center infrastructure components, wherein the reservoir is configured to be pressurized such that the fire suppression material is dispensed under pressure.

2. The data center of claim 1 , wherein at least one of the rack computing systems and at least one of the fire suppression devices are commonly coupled to the same one of the tiles.

3. The data center of claim 1 , wherein at least one of the one or more fire suppression devices is positioned to provide ballast to reduce displacement of at least one of the rack computing systems that is attached to a same tile as the at least one of the one or more fire suppression devices.

4. The data center of claim 1 , further comprising an air blocking device coupled to at least one of the tiles, wherein the air blocking device is configured to inhibit air from flowing under a cabinet of at least one of the one or more rack computing systems.

5. The data center of claim 1 , wherein the reservoir is configured to be pressurized by a pressure system that is coupled to the reservoir.

6. A system, comprising:
a raised floor configured to support one or more rack computing systems located above the raised floor;
a sub-floor space below the raised floor;
one or more electrical components in the sub-floor space; and
one or more fire suppression devices coupled to the raised floor, wherein at least one of the one or more fire suppression devices includes a reservoir in the subfloor space and wherein the at least one of the one or more fire suppression devices is configured to dispense under pressure, from the reservoir, fire suppression material within the subfloor space to at least one of the one or more electrical components in the sub-floor space, wherein the reservoir is configured to be pressurized such that the fire suppression material is dispensed under pressure.

7. The system of claim 6 , wherein the raised floor comprises one or more frame members and a plurality of tiles coupled to the one or more frame members, wherein at least one of the fire suppression devices is coupled to at least one of the one or more tiles.

8. The system of claim 7 , further comprising one or more rack computing systems, wherein at least one of the rack computing systems and at least one of the fire suppression devices are commonly coupled to the same one of the tiles.

9. The system of claim 8 , wherein at least one of the rack computing systems is coupled to the at least one tile by way of one or more spring devices.

10. The system of claim 8 , further comprising one or more one or more electrical cables, wherein at least one of the tiles comprises an opening configured to allow at least one of the electrical cables to pass from the sub-floor space to at least one of the rack computing systems.

11. The system of claim 8 , further comprising an air blocking device coupled to at least one of the one or more tiles, wherein the air blocking device is configured to inhibit air from flowing under a cabinet of at least one of the one or more rack computing systems.

12. The system of claim 6 , wherein the reservoir is configured to hold fire suppression material.

13. The system of claim 6 , further comprising a cooling air system, wherein the sub-floor space comprises a sub-floor plenum, wherein the cooling air system is configured to supply cooling air via the sub-floor plenum to space above the raised floor.

14. The system of claim 6 , wherein at least one of the fire suppression devices is configured to dispense fire suppression material in response to one or more fire conditions.

15. The system of claim 6 , further comprising:
a computing room above the raised floor; and
a computing room fire suppression system comprising one or more computing room fire suppression devices,
wherein the computing room fire suppression system is configured to dispense fire suppression material in the computing room, wherein at least one of the one or more fire suppression devices coupled to the raised floor operates independently of at least one of the computing room fire suppression devices.

16. The system of claim 6 , further comprising:
a tile configured to mount in or on one or more frame members of the raised floor; and
wherein at least one of the one or more fire suppression devices is coupled to the tile, wherein the at least one fire suppression device is configured to dispense fire suppression material into space under the tile when the tile is mounted in or on the one or more frame members.

17. The system of claim 16 , wherein the tile comprises one or more holes, wherein the one or more holes are configured to mount one or more rack computing systems.

18. The system of claim 17 , wherein the tile comprises one or more openings, wherein at least one of the one or more openings is configured to allow one or more electrical cables to pass from space under the tile to at least one of the rack computing systems.

19. The system of claim 16 , wherein the tile comprises one or more vents configured to allow air to pass through the tile.

20. The system of claim 16 , wherein the at least one fire suppression device is configured to dispense fire suppression material to one or more electrical power supply components in a space under the raised floor.

21. The system of claim 16 , wherein the at least one fire suppression device is configured to dispense fire suppression material to one or more cooling system components in a space under the raised floor.

22. The system of claim 16 , wherein the tile comprises a groove, wherein the groove is configured to couple with an air blocking device.

23. The system of claim 6 , wherein the reservoir is configured to be pressurized by a pressure system that is coupled to the reservoir.
