Problems solved by technology

[0017] In addition, in the above-mentioned Patent Document 2, although the restart order is performed based on the start order determination policy, the determination method of the policy is not described.
Moreover, in the above-mentioned Patent Document 3, although there is power information in advance that can specify the amount of power consumption required for the required computing resources, such power information cannot be actually carried out unless such power information is stored as data in advance through a large number of case studies. Work
[0018] That is, the above-mentioned prior art has the problem that in order to determine the sequence of server start-up and stop, it is necessary to establish a database through large-scale calculations and case studies, which requires huge costs for preparations before system operation.

[0042] Here, return to figure 1 , as the first embodiment of the present invention, the startup of a new server will be described. exist figure 1 Among them, 101 is a server load increase / decrease reporting device for notifying the server load increase or decrease, 102 is a server start / stop instruction executing device for instructing and executing the start / stop of each server, and 103 is a device for recording server start / stop A sequential storage device consisting of, for example, a memory, 104 is a server determining device that collects information on the operating status and temperature of servers to determine one server to be activated. In addition, these devices may be configured by, for example, a CPU including a memory storing a program for executing predetermined operations of each device. In addition, reference numeral 106 in the figure is a monitor for displaying the operating state of the server, and 107 is a monitor for requesting start and stop of the serve...

[0050] In the above embodiments, a case has been described in which the server determining means 104 among the devices performing the above-described operations collects information on the operating states and temperatures of each server to determine one server to start. However, the present invention is not limited thereto, and the server determination device 104 for determining one server to be activated may be a device that executes the simulation described in Patent Document 1 above.

[0051]Also, in this case, according to the present invention described above, it is possible to reduce the number of executions of the simulation to N times without performing the above-mentioned simulation to the N power of 2. More specifically, for example, in a case where there are 20 servers, it is possible to reduce the simulation of 2 to the power of 20 (=1048576) times to 20 times.

[0053] Next, use Figure 5~8 , the specific configuration and operation of the local cooling type information processing system which is an embodiment different from the outside air cooling type information processing system of the present invention will be described. The configuration and operation other than those described here are the same as those of the external air cooling type information processing system.

[0054] Figure 5 It is a plan view of an example of a localized cooling method in which air conditioners and racks housing servers are arranged in a row. 13 in the figure represents the support for accommodating the server, and 15 represents the air conditioner. In this example, an example in which air conditioners and server racks are alternately arranged is shown, but the air conditioners may be arranged for every two or more server racks. The server has a self-ventilating air supply mechanism, so that the air flows in a certain direction. In addition, simil...

Abstract

The invention provides a practical external air cooling and partial cooling method information processing system without the countercurrent or the recycling of the cooling air and a load distribution method. Each server is provided with a temperature sensor at an air suction opening of the cooling air, and when the number of the currently-running servers, and during the investigation of the stopping of the starting of the server, the smallest maximum value of the suction temperature of the server can be found out, and then the server can be started. On the contrary, when the number of the currently-running servers is reduced, the last started server can be stopped, and the integration can be effectively improved, and at the same time, the cooling device used to introduce the external air, and therefore the fault of the special server of the abnormal air suction temperature caused by the countercurrent or the recycling of the cooling air can be prevented.

Description

technical field [0001] The present invention relates to, for example, a so-called external air cooling type information processing system such as a data center composed of a group of information processing devices such as a server device and cooling equipment for cooling them, and an operation management method of the information processing devices in the system. The invention relates to an external air cooling type information processing system or a local cooling type information processing system and a distribution method for distributing work loads to information processing device groups in the system. Background technique [0002] At present, as the heat generated by information processing devices such as server devices increases in explosive growth, the power consumed by cooling equipment, so-called cooling power, also increases in order to cool the heat generated. The total power consumption of server devices and cooling power is The reduction of electric power has bec...
