Description

  The present invention relates to an information processing system including a plurality of computers and network devices connected by a network and a technique for reducing power consumption of the system.

Increasing the power consumption of IT systems has become a major problem due to the high performance of processors and the emergence of high-density IT (Information Technology) equipment such as blade servers. In response to this problem, development of technologies that reduce power consumption, such as low-power consumption processors and high-efficiency cooling methods, is underway, but there is a limit to the power-saving of a single device, and a greater power-saving effect is obtained To do this, efforts at the system level are necessary.
In particular, because the server consumes power even if the operating rate is 0 due to leakage current, the state of using a large number of servers with low operating rates is inefficient in terms of power, and the lower number of servers is as high as possible Power-saving operation is expected, such as using at the operating rate and turning off unused servers. On the other hand, virtual servers can be moved to other physical servers during operation, so when the load of a certain business is reduced, virtual servers running on servers with low operation rates are consolidated and operated. Power consumption can be reduced by reducing the number of physical servers. With the widespread use of virtual servers, the power saving operation as described above is becoming a reality.

However, if only some of the servers are operated with a high load, the area around these servers becomes a hot pool of heat, and if the overall cooling output is increased to cool the pool, the power required for cooling increases. Therefore, Patent Document 1 discloses a method for determining a server to be activated in consideration of heat distribution. Patent Document 2 discloses a method for optimizing the server configuration in consideration of the cooling capacity of the cooling device in the server.
Special table 2005-531047 JP 2004-126968 A

In the future, instead of cooling the entire machine room uniformly with a large-scale cooling device, a cooling device that can control the temperature locally will be important. For example, directional cooling devices and rack-based cooling devices attached to the back of the rack have already been shipped.
The cooling device currently determines the output based on the temperature of the fixed sensor and cools the predetermined range, but cools so that the server (s) that have been offset are intensively cooled by multiple cooling devices. It is considered that the sensor connected to the device and the air blowing direction can be changed. For example, in the case of equipment that cools with cold air from under the floor, the opening and closing of the floor grating plate (perforated tile) is controlled to change the location of the air blowing from under the floor, and the server that has been moved away is cooled intensively It is thought that it will become.

  When such a cooling device is used, when loads are concentrated on some servers (groups), the cooling capacity can also be aggregated.

  However, in actual operation, it is permissible for the power consumption to increase due to the consolidating work for the purpose of power saving, or for the thermal runaway to occur due to the lack of ability to cool the server (s) that have been gathered. Not. Therefore, before consolidating servers and cooling, when the load is concentrated on a certain server (group), the entire system including IT equipment and cooling device has sufficient cooling capacity to cool the aggregated part It should be estimated in advance whether the power consumption can be reduced.

  In order to realize such an estimate, it is necessary to identify a cooling device that can cool the aggregated server (s), and to check the cooling capacity and the power required for cooling when aggregated.

  However, at present, the cooling facility is controlled by the temperature detected by the connected sensor, and the relationship with the management target server is not managed. For this reason, it is impossible to estimate whether the cooling capacity is sufficient or how much electric power is required for cooling.

  Accordingly, the present invention provides an information processing system capable of determining a business arrangement for reducing the power consumption of the entire system as a business arrangement for a plurality of managed servers that access a storage device under cooling of the cooling device.

In the case of outside air cooling, the ability to cool with the same power consumption varies depending on the outside air temperature. Therefore, it is assumed that there are a plurality of cooling device profiles 125 for each temperature range of the outside air.

  The information shown in FIGS. 5 to 10 is described in the definition file by the administrator and input to the power saving control server 110. However, these pieces of information may be input from a GUI (Graphical User Interface) instead of a definition file, or may be acquired from another server via a network.

Next, the flow of power saving control will be described.
FIG. 11 is a diagram showing a power saving control flow in one embodiment of the present invention.
First, the operation information / power monitoring unit 111 of the power saving control server 110 reads the physical server configuration information 122 and the virtual server configuration information 123 (S1011), grasps the physical computer 200 and the virtual computer 221 to be managed, The operation information and power consumption are monitored (S1012), and a list of physical computers 200 having a load change is created (S1103). The presence / absence of a load change is determined based on whether or not a resource usage rate of a certain physical computer 200 continues for 10 minutes or more. If there is no load fluctuation, monitoring is continued.

  The operation information / power monitoring unit 111 refers to the operation information 710 that is the past history of the resource usage of the business of the virtual computer 221 operating on the physical computer 200 included in the list and the business schedule in the future. It is determined whether the low load on the physical computer 200 continues for a certain period. Then, the virtual computer 221 on the physical computer 200 that is determined to continue to be in a low load state is searched for a physical computer 200 that has a free space that can be moved, and all the virtual computers 221 that are operating on a certain physical computer 200 are searched for. When there is a physical computer 200 that has a free space that can be a migration destination, the virtual server arrangement generation unit 112 assigns any virtual server that is running on the physical computer 200 included in the list to the physical device that has the free space. A rearrangement (business arrangement) plan for arrangement on the server is created (S1104). When there are a plurality of virtual computers 221 on a certain physical computer 200, those virtual servers may be moved to the same physical computer 200 or may be different.

  Next, the virtual server arrangement generation unit 112 obtains the power consumption of the relocation plan, and selects a virtual server arrangement that consumes less power than the current power consumption (S1105).

  If the power consumption of the relocation plan is less than the current power consumption, the virtual server relocation unit 115 moves the virtual computer 221 according to the relocation plan (S1106), and the power supply control unit 116 The power of the physical computer 200 that has become is turned off (S1107). Further, when the cooling power calculation unit 114 determines that the setting of the cooling device 151 needs to be changed, the cooling control unit 117 issues an output change request to the management target cooling device control function 150 ( S1108).

  Finally, the power saving control server 110 returns to the operation information and power monitoring.

FIG. 12 is a diagram showing a relocation plan search flow in one embodiment of the present invention.
The virtual server arrangement generation unit 112 generates an arrangement pattern of the virtual machine 221 on the physical machine 200 and compares the original arrangement of the virtual machine with the power consumption of one or more relocation plans.

  The virtual server arrangement generation unit 112 first obtains a relocation plan for the virtual computer 221 with respect to the physical computer 200 based on the resource amount required for each virtual computer 221 and the resource amount included in each physical computer 200 (S1201).

The resource amount required by the virtual computer 221 is the maximum value of the resource usage of the business processed by this virtual computer. The average value and the maximum value of the resource usage of the business are obtained from the operation information history 121.
A specific method for generating a relocation plan is to estimate a resource usage rate when a virtual computer 221 operating on a physical computer 200 with less resource usage is moved to another physical computer 200 and move even if it is moved. The physical computer 200 having the sufficient resource amount of the previous physical computer 200 and having the highest utilization rate is selected as the movement destination. When there are a plurality of virtual machines 221 on the migration source physical computer 200, the arrangement of the migrated virtual machines 221 is determined as a relocation plan when a migration destination to which all the virtual machines 221 can be moved is found. .
At this time, the virtual server arrangement generation unit 112 refers to the virtual machine definition information 620, acquires the type of the business executed by the virtual server, and excludes the business that should not be moved from the relocation target. This is because a communication packet between the external program and the virtual server may be lost when a certain virtual server is moved from the currently executing physical server to another physical server. This packet loss is not a problem for many businesses because it is retransmitted by a protocol that has a retransmission function such as TCP. However, in a business that requires extremely high response performance, the requested performance may not be satisfied by retransmission. So do not move. It is assumed that such work is predetermined and there is a list of work that cannot be moved.
As a method for obtaining a rearrangement plan, it is possible to calculate an arrangement with the least power consumption by using a combinational optimization method without using the current arrangement of the virtual computer 221 as a base. However, in this case, there is a concern that the difference from the current virtual server arrangement is large and the number of times the virtual server is moved increases.

  Next, the power consumption of the physical computer 200 of the rearrangement plan is calculated. The virtual server arrangement generation unit 112 refers to the operation information history 121, obtains an average value of resource usage (amount) of work processed by each virtual computer 221, and considers the overhead of virtualization to each physical computer 200. The resource utilization rate (amount) is estimated (S1202).

  Since the virtualization overhead differs depending on the virtualization mechanism, the virtual server arrangement generation unit 112 refers to the virtual arrangement information 610 to acquire the type of the virtualization mechanism that is operating in the physical computer 200 to be arranged, and the virtual The resource utilization rate (amount) of the physical computer 200 is estimated with reference to the overhead value of the optimization mechanism. It is assumed that the overhead value for each virtualization mechanism is held inside the virtual server arrangement generation unit 112.

Here, in the case of outside air cooling, the cooling power calculation unit 114 acquires the outside air temperature with a temperature sensor placed outside the room, selects and refers to the cooling device profile 125 according to the current outside air temperature.
The cooling power calculation unit 114 refers to the server / cooling mapping 126 and determines that the heat generation amount of the physical computer 200 that aggregates the virtual computers 221 exceeds the cooling capacity in the current cooling capacity allocation. Change the distribution of
For example, by consolidating all virtual computers 221 into the physical computers 200 on the rack 1401a and the rack 4401d, the heat generation amount of the physical computers 200 on the rack 1401a and the rack 4401d exceeds the cooling capacity, and the physical on the rack 1401b and the rack 4401c When the cooling capacity of the computer 200 becomes unnecessary, the cooling capacity distribution is changed so that the cooling capacity of all the cooling devices is allocated to the rack 1401a and the rack 4401d. If cooling cannot be performed even if the cooling capacity distribution is changed, a notification that cooling is not possible is sent.

  Although the physical computer profile 124 of the present embodiment focuses only on the CPU that is the main heat generating component, the heat generation profile may be information according to the utilization rate of other components in addition to the CPU.
