  Hereinafter, embodiments according to the disclosed technology will be described.

  First, before describing the details of the embodiment, the necessity of grasping the state of power in the data center, which is a premise in the system provided by each embodiment described later, will be described.

  Data centers need the ability to continue supplying power to customer racks without interruption. For this reason, the data center is equipped with a private power generator that can withstand commercial power interruption and a UPS (Uninterruptible Power Supply) for switching between commercial power and private power generator without interruption.

  Even if the measures described above are taken, there is a possibility that the power supply equipment may break down due to aging of the power supply equipment or insufficient maintenance.

  In addition, when a power supply disconnection accident occurs in a data center, the impact is significant.

  As a measure for the above, in data centers, the availability of power supply is ensured by making power supply paths redundant and using high-quality power distribution equipment such as distribution boards and branch boards. Also, a service that can use this redundant power supply path in the service to the customer is provided. This is a service that can continue power supply in a route other than the down power supply route even if a failure occurs in the power supply facility. Further, among power supply facilities, there are many that are more expensive as the failure risk is lower.

  However, the redundancy of the power supply is to secure a capacity of power not used (capacity of power used only when a failure occurs) while distributing paths. Therefore, the operation manager of the data center must always grasp the power capacity conditions (1) to (4) below.

(1) Power consumption normally used in power supply equipment (2) Maximum power capacity that can be used by power supply equipment (3) Rated capacity of power supply equipment (4) In the event of failure of power supply equipment (main power supply) Alternative power supply equipment (main power supply) (redundant configuration combination) and power capacity to be secured in case of downtime

  In addition, the operation manager of the data center must always know the range of influence when a power supply disconnection accident occurs (which rack affects which power supply equipment fails). Therefore, it is necessary to always grasp the following situations (5) and (6).

(5) Connection between power supply equipment and rack (6) Rack redundancy level and redundancy

  Next, the problem of grasping the contents (1) to (6) will be described.

  Specifically, the following methods (A) to (D) are conceivable as methods for grasping the contents of the above (1) to (6).

(A) The power consumption is measured in real time, and the situation is grasped by constantly monitoring. However, since the operating status (operating rate) of the equipment in the rack is not always constant, changes in usage status are monitored by, for example, statistically analyzing the latest power usage trend.
(B) Regardless of the power usage status of the equipment in the rack, the maximum power that can be used by the equipment in the rack is determined, and the power capacity of the upper power supply equipment is managed. In order to determine the maximum power that can be used by the equipment in the rack, for example, there is a method of obtaining the maximum power by multiplying the total rated capacity of the equipment in the rack by a coefficient in the range of 30% to 60%. Further, there are a method for obtaining past maximum power consumption from historical data and a method for predicting maximum power using statistics.
(C) The configuration management of the connection between the rack and the power supply facility and the connection with the upper power supply facility is performed.
(D) The above (A) to (D) are summarized, and the power usage status and maximum power of each power supply facility are managed.

  For example, the power supply system of the data center as shown in FIG. 1 can be managed by the display as shown in FIG.

  However, the power supply facilities owned by the data center may be very large depending on the size of the data center. Therefore, simply by managing the configuration diagram and load status as shown in FIGS. 1 and 2, it is possible to grasp at a glance the effects of unexpected power supply equipment failures and accidents for the following reasons (a) and (b): It may be difficult to do.

(A) A power supply facility related to power distribution from a power supply facility (extra power receiving facility) in a data center to a rack has a multi-stage configuration and a large number of rack distribution boards. Therefore, if the configuration of the actual power supply path is represented by a diagram instead of the schematic diagram shown in FIG. 1, the number of lines indicating the relationship increases as shown in FIG. FIG. 3 shows an example of a part of the configuration of the A-system UPS to rack distribution board in the schematic diagram of FIG.

(B) The number of racks that can be accommodated in the data center and the number of distribution breakers for racks is very large, and depending on the type of redundant power supply service, which level of power supply equipment is used as the power supply source for each rack There is a difference. FIG. 4 shows a power configuration depending on the type of redundant service. As shown in FIG. 4, if a single unit or a small number of racks are used, a redundant configuration can be expressed, but it is difficult to express a plurality of racks redundantly at the same time.

  As a result, data center managers must have sufficient power capacity to satisfy both the effective use of power supply capacity to racks and the securing of free power capacity in preparation for failure of power supply facilities. Management is required.

  As described above, there are problems (a) and (b) in data center management. Therefore, in the power load management apparatus according to each embodiment to be described later, the above problems (a) and (b) are solved, and even in a large data center, the situations (1) to (6) above Express as concisely and reliably as possible.

  Hereinafter, as a summary of the embodiment, a solution to the problems (a) and (b) will be described.

  In the power load management device according to each embodiment to be described later, the status grasp targets are power branch configuration, power usage (usage rate), power usage balance, affected equipment / rack when power supply equipment is down, power loss of power equipment Rate. Here, the power branching configuration represents a branching configuration of the power supply path from the UPS to the rack. The power usage (usage rate) represents the power usage and usage rate such as measured power, usable power (maximum power), rated capacity power, etc. of the UPS, distribution board master, distribution breaker, and the like. The power usage balance represents the power usage balance of a power supply facility that is a power supply path from the UPS to distribution to the rack. The affected equipment / rack when the power supply equipment is down is a rack that is affected when a certain power supply equipment fails or is stopped. By identifying the affected equipment and racks when the power supply equipment is down, it is possible to grasp which racks are affected and manage the service level compliance with customers. The power loss rate of the power equipment is a difference in power between power reception and power distribution of each power supply equipment. The power loss status is managed from the power loss rate of the power equipment.

  Hereinafter, as a summary of the embodiment, a solution to the problems (a) and (b) will be described.

  As a method for solving the problems (a) and (b), in each embodiment described later, an expression method for managing the power capacity of the data center is adopted based on two points of interest.

  First, the first point of interest “characteristics of power capacity of power reception / distribution of data center power supply facilities” will be described.

  FIG. 5 shows an example of the power capacity of the distribution board used in the data center. As shown in the example of FIG. 5, the power supply equipment used in the data center basically has the following relationship between power reception (power input side) and power distribution (power output side) of the power supply equipment itself.

Rated power receiving capacity ≤ Total rated power distribution capacity = Σ (Receiving rated capacity n at distribution breaker or branch destination)

  A feature of the power supply facility is that a larger rated capacity is set in the sum total on the power distribution side than on the power reception side. In the distribution breaker (or branch destination) that distributes power from the distribution board, the circuit breaker trips when 100% of the distributed power is used, so 100% of the rated capacity of the receiving power is not used. Therefore, if the sum of the distribution rated capacities of the distribution board is not larger than the power receiving rated capacity, it is not possible to use power close to the power receiving rated capacity. Accordingly, as described above, a larger rated capacity is set in the sum total on the power distribution side than on the power reception side. Moreover, since the distribution board for racks distributes power to many racks, it is assumed that the number of breakers is increased and 30 to 40% of the power receiving rated capacity of each breaker is used. Because of the magnitude relationship between the power receiving rated capacity and the sum of the power distribution rated capacity, when the amount of power used by the distribution side equipment of the distribution board is equal to or greater than the power distribution rated capacity of the distribution board, The power board trips. For this reason, the upper limit of the amount of power used on the distribution side must be managed so as to be less than the rated power receiving capacity. If a distribution board trips, all distribution of that distribution board stops.

  Next, the second focus point “power management viewpoint (difference between the main power source side and the terminal side viewpoint)” will be described.

  When managing the power capacity of the data center, the main power supply side emphasizes power usage and free capacity status, and the end side (distribution to racks) emphasizes the balance of power usage and status of variation. doing.

  This is because the power supply capacity on the main power supply side is limited as a data center, and the power supply equipment closer to power reception is more affected by equipment failure, and capacity management is more important as power reception is closer. It is.

  In addition, since 100% of the rated power receiving capacity is rarely used on the terminal side, there is room for power distribution capacity, so depending on the distribution method, it may be used for power distribution such as preferential use of a specific distribution board. This is because bias may occur. In addition, when there is a bias in power distribution, a specific power receiving facility uses power close to the power receiving rated capacity, and power distribution equipment that cannot be used due to the power receiving rated capacity appears. In addition, if an attempt is made to force use of an unoccupied power distribution facility, it must be used in a way that impairs efficient use of power, such as lengthening the wiring of the power source. Therefore, it is important for the terminal side to be connected to each distribution facility in a well-balanced manner.

  Next, in each embodiment to be described later, an expression as a data center power management method based on the above-described first and second focus points will be described.

First, from the above-mentioned first point of interest, the relationship “power receiving rated capacity ≦ total power distribution rated capacity” is expressed as the difference in the length of the arcs of two circles having the same central angle but different radii. The length of the arcs having the same central angle is longer in the outer arc having a longer circle radius than in the inner arc having a shorter circle radius. Therefore, the relationship between the inner radius r 1 and the outer radius r 2 can be expressed as a ratio of the power receiving rated capacity and the power distribution rated capacity by the expression as shown in FIG. In FIG. 6, an arc L 1 represents the power receiving rated capacity, an arc L 2 represents the sum of the distribution rated capacities, and has a relationship of r 1 : r 2 = L 1 : L 2 . For example, in the example of the distribution board shown in FIG. 5, the power receiving rated capacity is 90 kVA, and the total distribution rated capacity is 260 kVA, and therefore, it can be expressed as r 1 : r 2 = 90: 260. Further, an area where the arc L 1 and the arc L 2 are connected to each other (the right side is connected to the right side and the left side is connected to the left side) is the area of the power supply facility. Hereinafter, connecting both end points means connecting the right side with the right side and the left side with the left side.

In the case of “power receiving rated capacity = total power distribution rated capacity”, the relationship between the inner radius r 1 and the outer radius r 2 is originally “r 1 = r 2 ”. As shown in FIG. 8, r 2 may be expressed by increasing it according to an adjustment parameter (for example, about 5% of r 1 ).

In addition, in the case of “power receiving rated capacity << total power distribution rated capacity” (the sum of power distribution rated capacity is considerably larger than the power receiving rated capacity), even if the power distribution rated capacity is faithfully expressed, The power cannot be used. Therefore, r 2 is a predetermined length of r 1 as shown in FIG. 9 (e.g., 2-fold r 1) may be leveled off to expressed not to exceed (r 2 ').

  In addition, the angle θ, which is the central angle of the arc, is determined by the ratio of the power capacity of the power supply facilities in the same hierarchy so that the total of the same hierarchy is 360 °. For example, when there are four power supply facilities on the same level and the power capacity ratio of each facility is 1: 1: 1: 1, θ of each facility is 90 °. Here, the hierarchy represents the distance from the main power supply (or power supply), and it is assumed that only the same type of power supply equipment exists in the same hierarchy. Further, since the power consumption does not exceed the power receiving rated capacity, as shown in FIG. 7, the length of the inner arc (the length of the arc of the power receiving side rated capacity) is set to a part of the outer arc. The area represented by the length and connecting the two end points of the arcs can be represented as the usable maximum power area. Further, the length of the inner arc (power usage amount) can be represented by the length of a part of the outer arc, and the region connecting both end points of the arcs can be represented as the power usage region. Therefore, the difference between the maximum usable power area and the power consumption area can be expressed as a usable free capacity.

  Next, a method for expressing the relationship between the input and output of the multistage power supply facility will be described.

  When the output of a certain power supply facility A becomes the input of another plurality of power supply facilities B, as shown in FIG. 10 and FIG. The area of the power supply facility B can be expressed by the law. Thereby, the relationship between the input and output of a multistage power supply facility can be expressed. Note that FIG. 10 shows a case where the sum of the distribution rated capacities of A matches the total power receiving rated capacities of the power supply facilities at the same level as B connected to A. In addition, FIG. 11 represents a case where the total sum of the distribution rated capacities of A is smaller than the total power receiving rated capacities of the power supply facilities at the same level as B connected to A.

  For example, if the main power supply such as UPS is a center circle, the relationship between the distribution rated capacity of the upper power supply equipment and the power receiving rated capacity of the lower power supply equipment, and the amount of power used for the multistage power supply equipment. The relationship can be expressed as shown in FIG. In FIG. 12, the UPS is defined as the first layer, the second layer PDU connected to the UPS is represented by the area next to the first layer, and the third layer PDF is similarly represented in the second layer PDU. Represented in the outer area. In addition, for the first tier, the power usage amount and the maximum usable power capacity are expressed, and for the other tiers, the power usage amount, the maximum usable power capacity, and the rated capacity are expressed. Represents the relationship. In addition, the area | region of the electric power supply equipment connected to the input side of the electric power supply equipment is arrange | positioned in the center point side of the arc of the fan-shaped inner side which is an area | region showing electric power supply equipment in FIG. Moreover, the area | region of the electric power supply equipment connected to the output side of an electric power supply equipment is arrange | positioned on the opposite side to the center point of the arc outside a fan shape.

  Since the amount of power used depends on the capacity of the power supply equipment closer to the center of the circle, the power closer to the center inevitably becomes the sum of the capacity of the power supply equipment outside the circle. The expression on the outside of the circle (the end of the power supply path) becomes smaller (thin), making it difficult to express the amount of power used for each power supply facility, but see the balance and variations in the power consumption of the entire distribution facility Suitable for.

  Therefore, by looking at the usage rate of the power supply equipment closer to the center, it is possible to grasp the situation that emphasizes the power usage and availability, and the terminal side grasps the situation that emphasizes the balance (variation) of power usage Can do. Therefore, management suitable for the viewpoint of power management as the data center described in the second point of interest described above is enabled. Further, when the UPS output is redundant in two systems, it can be similarly expressed as shown in FIG. In addition, in FIG. 13, the expression of the relationship of the electric power consumption of each power supply equipment is abbreviate | omitted.

  In the example of FIG. 3, only the configuration corresponding to the upper half (only the A system) of the example of FIG. 13 is expressed. However, in the example of FIG. Compared to the expression shown in, the expression is easier to see. Furthermore, as shown in FIG. 12, the power consumption of each power supply facility can be expressed simultaneously. Thereby, even if it is a data center which has many electric power supply facilities, the structure (connection relationship) and electric power usage condition of an electric power supply facility can be expressed with one figure.

  Next, a method for expressing the power loss rate of the power equipment will be described.

  Using the above-described expression method, the power loss situation of the power supply facility can be expressed as shown in FIG. 14 in addition to the power capacity / usage amount / free capacity. Here, FIG. 14 will be described. The power usage on the power receiving side in FIG. 14 represents the power input to the target power supply facility, and the power usage on the distribution side is the usage in the target power supply facility. Represents the power being used. Therefore, the inner arc representing the power usage on the power receiving side, the area connecting the end points of the arc representing the length of the arc with the outer arc, and both ends of the outer arc representing the power usage on the distribution side The difference between the point and the area connecting the two end points of the arc representing the power usage on the power receiving side is represented as a power loss. Thus, it is possible to easily identify a failure by grasping the power loss situation.

  Normally, the power loss is negligibly small in the branch / distribution panel other than the UPS, but the power loss becomes large if there is a power loss due to heat generation of the equipment or the power line, or an abnormality or failure of the actual equipment. Therefore, the magnitude of the power loss can be easily grasped by expressing it as shown in FIG. Since the UPS passes through power storage, the power loss rate is considerably larger than that of a distribution board or the like, but in this embodiment, the UPS power loss is not considered.

  Next, the expression of the influence range of the failure of the power supply equipment will be described in relation to grasping the status of the affected equipment / rack when the power supply equipment is down.

  If any of the power supply facilities fails using the above-described expression method, the influence can be expressed as if all the facilities located outside the facility are affected. For example, when the PDU-A2 fails as shown in FIG. 15, it can be easily understood that the rack distribution boards (PDF-A2-1 to 15) located outside the PDU-A2 are affected by the failure.

  Next, in relation to grasping the status of the affected equipment / rack when the power supply equipment is down, the power distribution status to the rack and the representation of the redundant configuration will be described.

  In the physical configuration, the power supply facility viewed from the rack is a breaker for the rack power distribution panel to which the rack is actually connected. However, for a redundantly distributed rack, the power path on the way is the power If the source is not down, there is no problem. Therefore, the logical configuration can be expressed as if it is connected to the power supply source, ignoring the expression of the redundant path on the way. Therefore, if there is the physical configuration of FIG. 4, the physical configuration of FIG. 4 can be replaced with a logical configuration as shown in FIG.

  In order to be able to refer to this logical configuration from the created graph as shown in FIG. 12, the link (the part that opens another screen when clicked on the screen) is superimposed on the expression of the power usage state according to the law as shown in FIG. . Then, by operating (selecting) this link, a list of redundant power distribution racks related to the corresponding power supply facility is displayed. An example of a graph when links are superimposed is shown in FIG.

  In each embodiment described later, UPS redundancy, system redundancy, distribution panel redundancy, and breaker redundancy are defined as redundancy types.

  UPS redundancy refers to a redundant configuration in which power can be supplied from another UPS even if any UPS fails. Therefore, as shown in FIG. 17, a link is added to the center of a circle that can be shared with a plurality of UPSs. The circumferential length of the link is, for example, the length of the arc outside the one-system UPS.

  The system redundancy is a redundant configuration in which even if any UPS output fails, the power supply is not interrupted unless the output UPS has failed. Therefore, as shown in FIG. 17, a link is added to the outside (outside arc side end) of the output UPS.

  The distribution board redundancy is a redundant configuration in which power supply is not interrupted if the UPS output system of the output source does not break down even if any of the server distribution boards breaks down. Therefore, as shown in FIG. 17, a link is added inside the UPS output system (inner arc side end).

  Breaker redundancy is a redundant configuration in which power supply is not interrupted unless a rack distribution panel fails even if any breaker fails or trips. Therefore, as shown in FIG. 17, a link is added to the inner side (inner arc side end portion) of the rack distribution board.

  In the power load management apparatus according to each embodiment to be described later, by using the above expression method, the power usage status of the entire data center, the rated capacity of the power supply equipment, the maximum usable power capacity, and the power supply equipment are used. The amount of power used can be expressed concisely. In addition, the connection relationship (configuration) of the power supply equipment and the range of influence when the power supply equipment fails can be simply expressed. Moreover, it is possible to easily obtain a list of redundant power distribution racks related to the power supply equipment.

  Hereinafter, each embodiment will be described in detail with reference to the drawings. It is assumed that “power receiving rated capacity” and “total power distribution rated capacity” of each power supply facility used in each embodiment are defined in advance. In addition, the configuration information (physical configuration and logical configuration) of each power supply facility in the target data center is similarly determined in advance. Moreover, in each embodiment, detailed description is omitted about the description about the expression method used as a premise mentioned above, and the content common to the outline | summary of embodiment.

In this case, the screen drawing control unit reads the graph in which the rated capacity area and the usable maximum power capacity area stored in the screen information storage unit 38 are drawn, and sets the power usage area and the power loss area at regular intervals. A drawing process may be performed.

  Moreover, in 1st Embodiment, although the magnitude | size of the sector of each power supply equipment was determined using the information of the sum total of a power receiving rated capacity and a distribution rated capacity, it is not limited to this. If you only want to know the connection (configuration) of the power supply facilities in the data center, determine the central angle of the fan-shaped area that indicates each power supply facility according to the number of lower layers connected to the upper layer. May be. Specifically, each region of the power supply facility of level 1 is a region obtained by dividing 360 ° by the number. In addition, for each of the power supply facilities of level 2, each of the regions having a central angle obtained by dividing the central angle of the region indicating the power supply facility as the connection source by the number of the power supply facilities of level 2 to be connected It is good also as an area | region. The same processing is performed for layer 3 and subsequent levels. By performing the processing in this way, the central angle of the area (fan shape) of the power supply facility is determined by the number of power supply facilities for each level.

Determine whether the numbers are the same.

  Specifically, in FIG. 24, since all rack distribution boards (PDF) are connected to only one PDU of the intermediate layer, it can be determined that the number of intermediate layers is the same. On the other hand, in FIG. 43, when comparing PDFA-1-1 and PDFA 1-3, PDFA-1-1 is connected to only one PDU in the intermediate layer. However, the PDFA 1-3 is connected to the intermediate layer DTR-A1, and the DTR-A1 is further connected to the intermediate layer PDU. Therefore, it is determined that the number of intermediate layers is different between PDFA-1-1 and PDFA1-3. The DTR is an example of a third type power supply facility, and the PDF is an example of a fourth type power supply facility.

  Next, a case will be described in which the preprocessing unit 450 determines that the number of intermediate layers is not the same in the physical configuration of the power supply facilities of all distribution layers as shown in FIG. In this case, the pre-processing unit 450 adds the total rated capacity (power receiving rated capacity and the sum of the distribution rated capacity) of each power supply facility of the distribution layer with a small number of intermediate layers connected to the same power supply facility. The configuration shown in FIG. 45 is created in which virtual facilities having And the pre-processing part 450 produces | generates the hierarchical structure which listed the applicable electric power supply equipment including the virtual equipment for every number of hierarchies from the produced structure, as shown in FIG. 46, and screen drawing control part Output to 460.

For each layer, the screen drawing control unit 460 creates a graph to which a link is added as shown in FIG. 47 as shown in FIG. 47, and outputs the screen information of the graph to the output device. However, in the second embodiment, when virtual facilities exist in each layer, the sum of the power receiving rated capacity and the distribution rated capacity of the virtual facility is added to the total power receiving rated capacity and the total power distribution rated capacity of each layer. Process to include. Further, θ x of the first power supply facility to be processed existing in the next hierarchy connected to the virtual equipment is the physical power supply equipment connected to the same power supply equipment of the previous hierarchy. A value obtained by adding θ 1 of the power supply facility to θ x is used. Referring to the example of FIG. 45, PDFB2-1 is, in assumptions process is faster than PDFB2-2, θ x of PDFB2-1 uses the sum of the theta x and theta 1 of DTR-B2. Note that the virtual equipment is not subject to drawing processing. Since other processes are the same as those in the first embodiment, the description of the configuration and the description of the operation are omitted.

  As described above, according to the second embodiment, even if the configuration of the power supply facility is not constant, the connection relationship of the power supply facility can be easily displayed by using the virtual facility.

  In the second embodiment, the case where a hierarchical structure in which virtual facilities are added is generated depending on whether or not the number of intermediate layers is the same has been described. However, configurations of layers other than the intermediate layer may be targeted.
