Description

  The present invention relates to a linkage control system for facilities including ICT equipment, air conditioning equipment, and power supply equipment, and more particularly to a linkage control system for ICT equipment and facilities suitable for facility control in an information communication machine room (data center).

  In recent years, with the advancement of IT in society, information communication devices and devices (hereinafter collectively referred to as ICT devices) are rapidly increasing in speed, capacity, and density. These devices are generally stored in a 19-inch server rack conforming to the US IEA standard and housed in an information communication machine room (data center). Server racks often take in cool air from the front and exhaust from the top or back, and each rack is arranged in a horizontal row in the same direction. In the machine room, such rack rows are arranged in a plurality of rows with the intake surfaces and the intake surfaces of the adjacent rows facing each other and the exhaust surfaces and the exhaust surfaces facing each other. In such machine room air conditioning, there are cases in which a rack row is divided into a plurality of zones, and an air conditioner is arranged in each zone to control each zone (for example, Patent Document 1).

On the other hand, the design of power supply quality (reliability) for ICT equipment has been conventionally performed according to the service grade of the data center. FIG. 10 is a diagram showing an example of a power supply (power supply) system for ICT equipment and air conditioners in a conventional data center. In the figure, uninterruptible power supply facilities (UPS) 101a-101c are installed in zones (Z11-Z13) that provide services requiring a high level of reliability. The capacity (backup time) of each UPS is designed at a different time depending on the required reliability, and the zones (Z13, Z12) where the failure of starting the emergency engine 102 should be considered are relatively long (here Then, backups of 3 hours and 1 hour are secured. In the zone (Z11) based on the premise that the emergency engine is started, the minimum necessary backup time (15 minutes in this case) is ensured. Also, no UPS is installed in the zone (Z14) where service suspension is allowed. Further, as for the zone air conditioners 105a to 105d as the air conditioning equipment, it is rare that a UPS is attached as shown in the figure, and power supply backup only for the emergency engine 102 is common.
Special table 2008-502082 gazette

In such a conventional power supply system, it is difficult to dynamically change the power supply quality during data processing in response to changes in the actual information processing amount and processing reliability in each zone. For this reason, in the case of a power failure or the like, a zone with a high quality (reliability) requirement is stopped, while a service level reversal phenomenon in which a zone with a low quality requirement is extended may occur. In this case, the problem can be solved by increasing the power supply quality in all zones, but the cost burden becomes excessive, which is not realistic.
Furthermore, since the power supply quality of the ICT equipment and the air conditioning equipment is different as described above, there are cases where the room temperature rises due to the stoppage of the operation of the air conditioner and the system goes down even if the ICT equipment continues to operate during a power failure or the like. This detracts from the significance of connecting the ICT device to the UPS. However, making all air conditioning facilities uninterruptible becomes excessively costly.

This invention is for solving such a problem, and provides the linkage control technique which ensures the power supply quality and air-conditioning quality according to the information processing amount or quality which should be serviced.
The gist of the present invention is as follows. That is, the ICT equipment and facility linkage control system according to the present invention is:
(1) In the information and communication machine room, including operation control of one or more air conditioners, data processing control of one or more ICT devices belonging to a plurality of air conditioning zones shared by each air conditioner, commercial power supply and emergency power supply The ICT equipment and facility linkage control system that links and controls the ICT equipment group and the power supply system control for supplying power to the air conditioner, and the number of air conditioning zones according to the processing quality level for a given data processing load Means for sharing the data processing load classified into the ICT equipment group belonging to each corresponding air conditioning zone, and power supply quality corresponding means for making the power supply quality of each air conditioning zone correspond to the processing quality level. It is characterized by.

In the present invention, “ICT equipment” includes information communication equipment and devices such as servers, storages, and routers.
“Processing quality” refers to the degree of reliability that does not cause service interruption during data processing.

(2) In (1) above, the power supply quality is any one of a combination of a commercial power system and an emergency power generation system, or a combination of a commercial power system, an emergency power generation system, and an uninterruptible power supply (UPS) system. It is characterized by being.
(3) In each of the above inventions, the UPS system includes a plurality of UPS systems having different backup times.
(4) In each of the above inventions, the power supply quality corresponding means is power supply system switching means for switching the power supply quality without interruption.

The ICT equipment and facility linkage control method according to the present invention includes:
(5) In the information communication machine room, operation control of one or more air conditioners, and data processing control of one or more ICT devices (hereinafter referred to as a target ICT device group) belonging to a plurality of air conditioning zones shared by each air conditioner; , An ICT device that includes a commercial power supply and an emergency power supply, and a power supply system control that supplies power to an ICT device group and an air conditioner. The number of air conditioning zones according to the processing quality level, the step of sharing the classified data processing load to the ICT equipment group belonging to each corresponding air conditioning zone, and the power supply quality of the air conditioning zone without interruption And corresponding to the processing quality level.

(6) In the information communication machine room, the data processing control of the target ICT equipment group and the power supply system control configured to include the commercial power supply and the emergency power supply and to supply power to the ICT equipment group and the air conditioner are linked and controlled. A method for controlling the linkage between ICT equipment and a facility, in which, when an air conditioner is completely stopped due to a power failure at a given data processing load, a step for estimating a repowering grace time for the zone and a repowering grace time are considered. A step of changing the power supply quality of the air-conditioning zone without instantaneous interruption so that the processing quality level is sometimes exceeded.
The present invention assumes a system in which the power supply quality on the air conditioner side is not linked to the ICT equipment side when the ICT equipment side is backed up by an uninterruptible power supply, and the emergency power generation device (engine) starts up at the time of a power failure. This is to ensure that the room temperature is below the allowable limit temperature. Specifically, after predicting a rise in room temperature assuming that the air conditioner will be completely stopped at the time of a power failure, select the power supply quality on the air conditioning system side (for example, 15-minute UPS backup assuming no uninterruptible power supply, engine startup, etc.).
Here, “re-power supply grace time” means that in the zone where the ICT equipment is backed up uninterruptibly, if the air conditioner stops at a given data processing load (∝power consumption), the zone is allowed Time to reach the limit temperature.

According to the present invention, the processing quality (reliability) of the data processing service in the data center can be dynamically controlled as required.
In addition, since the power supply quality of the ICT device and the air conditioning equipment is the same, the operation of the ICT device and the air conditioner can be synchronized.
In addition, data processing according to the required quality can be performed with the minimum necessary equipment, so that cost performance is excellent.

With reference to FIG. 7, S201 and S202 are the same as S101 and S102 of the first embodiment. Next, a repowering grace time for each zone is calculated from the table of FIG. 8 (S203). Here, as shown in FIG. 9, it is assumed that the repowering grace time of zones Z1-Z4 is t1, t2, t3, and t4, respectively. In this case, in order to make the backup time (30 minutes) or more of the ICT equipment group longer, the power supply system is set to zone Z1: UPS 31b (10 minutes), zone Z1: UPS 31a (20 minutes), zone Z1: no UPS, zone Z4: It is sufficient to switch to UPS 31c (5 minutes). After the switching is completed, data processing is executed (S204).
In addition, the backup time of each UPS is an example, and the UPS capacity according to the actual situation can be selected.
