Description

[Technical Field]

[0001] The present invention relates to an installation position presentation device, an installation position presentation method, and an installation position presentation program, and more particularly to an installation position presentation device that presents optimal installation positions for additional or successor equipment when adding or replacing equipment related to a server (including network equipment, power supply equipment, etc.) to a rack. [Background technology]

[0002] Patent Document 1 discloses a method for defining rules for each device and determining the rack mounting position of the device. Patent Document 2 discloses a method for sorting the devices by the number of cables connecting them and the weight of the devices and determining the mounting position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-228167 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-070617 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even the technology described in Patent Document 1 does not disclose a method for determining the installation position of additional equipment when adding equipment to a rack that already has equipment installed. Furthermore, it is necessary to check the weight and current consumption of the equipment to be installed and ensure that it is within the rack's allowable weight and the power strip's allowable current. In other words, it requires time and effort to check these conditions. In addition, when equipment reaches the end of life (EOL), it is necessary to replace it with a successor device by mounting it in the rack and transferring the settings. To determine the EOL of a device and its successor, you must research vendor information and be aware of when to purchase and replace the successor device.

[0005] The present invention has been made to solve such problems, and aims to provide an installation position presentation device, an installation position presentation method, and an installation position presentation program that allow server-related equipment to be installed in a rack in an appropriate arrangement. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a mounting position suggestion device that suggests mounting positions for server-related equipment on a rack, comprising: a weight determination unit that determines whether the total weight of the equipment is within the allowable range of the rack; a current determination unit that determines whether the current flowing through the equipment mounted on the rack is within the allowable current of a power strip attached to the rack; and a mounting position suggestion unit that suggests positions where the equipment can be mounted on the rack based on the determination results of the weight determination unit and the current determination unit. Note that the symbols and letters in parentheses are symbols and the like used in the embodiments and do not limit the present invention. [Effects of the Invention]

[0007] According to the present invention, server-related devices can be mounted in a rack in an appropriate arrangement. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that each drawing is merely a schematic illustration to allow a sufficient understanding of the embodiments. In addition, common or similar components in each drawing are designated by the same reference numerals, and redundant explanations thereof will be omitted.

[0010] (First embodiment) FIG. 1 is a configuration diagram of a mounting position presentation device according to a first embodiment of the present invention. The mounting position presentation device 100 presents an appropriate mounting position (space) when mounting equipment related to a server 180 (FIG. 2B) in a rack (server rack) 150 (FIGS. 2A and 2B). The mounting position presentation device 100 is also a support device that supports a user in determining a mounting position. Here, the equipment includes not only the server 180 but also network equipment such as a router, power supply equipment including a UPS (Uninterruptible Power Supply), and the like. The mounting position presentation device 100 is also applicable to large-scale data centers equipped with multiple racks. The mounting position presentation device 100 is used not only when a new installed rack is produced (i.e., when mounting equipment in an empty rack 150), but also when adding new equipment (additional equipment) to an existing rack 150 or when replacing equipment that has reached its end of life (EOL) with a successor equipment (i.e., when mounting additional equipment in a rack 150 that already has equipment mounted therein or when replacing equipment). Here, EOL refers to the end of the equipment's life cycle, and once EOL is reached, maintenance support from the manufacturer will no longer be available.

[0011] The mounting position presentation device 100 is, for example, a PC (Personal Computer), and includes a control unit 50, a storage unit 60, and an operation display unit 70. The control unit 50 is a CPU (Central Processing Unit), and executes a mounting position presentation program to realize the functions of a mounting position processing unit 10, a device reception control unit 20, a mounting position output control unit 30, and an EOL device notification unit 40.

[0012] The mounting position processing unit 10 indicates which rack 150 (FIGS. 2A and 2B) and which unit number of the rack-mounted equipment received by the equipment reception control unit 20 should be mounted on, based on the equipment information 200, shelf information 300, rack mounting information 400, and rack information 500. The mounting position processing unit 10 also indicates whether the equipment to be mounted can be mounted on the same rack 150 as existing equipment that requires a cable (such as a LAN (Local Area Network) cable or an FC (Fiber Channel) cable) to be connected.

[0013] The mounting position processing unit 10 implements the functions of a weight determination unit 1, a current determination unit 2, a mounting position presentation unit 3, and a power determination unit 4. The weight determination unit 1 determines whether the total weight of the devices to be mounted is within the allowable range of the rack 150 (FIGS. 2A and 2B). The current determination unit 2 determines whether the current (current consumption) flowing through the devices mounted on the rack 150 is within the allowable current of the power strips 161, 162, 163, 164, 165, 166, 167, and 168 (FIGS. 2A and 2B) attached to the rack. The mounting position presentation unit 3 presents mounting positions in the rack where devices (additional devices or replacement devices) can be mounted, based on the results of the weight determination unit 1 and the current determination unit 2. Multiple mounting positions may be presented. When multiple mounting positions are presented, the user (maintenance personnel) selects and determines the appropriate position. The power determination unit 4 determines whether the total power consumption (VA) of the devices is within the allowable power (VA) of the rack. If the commercial power supply voltage is the same, the power determining unit 4 may determine whether the total current consumption (A) of the devices is within the allowable current (A) of the rack.

[0014] The equipment reception control unit 20 receives, via the operation / display unit 70, the names of equipment to be added or replaced and the names of existing equipment to which cables need to be connected, and receives equipment information 200 from the storage unit 60. The installation position output control unit 30 causes the operation / display unit 70 to display one or more installation positions presented by the installation position presentation unit 3. The EOL equipment notification unit 40 notifies the user (maintenance personnel) of information about equipment approaching EOL and its successor equipment based on the information in the "EOL" column 208 (FIG. 3) and the information in the "Successor Equipment" column 209 (FIG. 3) of the equipment information 200. The notification timing, such as one year before EOL, is determined by the user. These functions present the installation positions (e.g., unit numbers in the rack 150 (FIGS. 2A and 2B)) of servers, network devices, and power supply devices including UPSs. In other words, the user is assisted in determining the installation positions.

[0015] The storage unit 60 includes a non-volatile storage unit that stores device information 200, shelf information 300, rack mounting information 400, and rack information 500, and a volatile storage unit (not shown).

[0016] FIG. 2A is a simplified diagram showing an example of mounting on the upper level of the rack, and FIG. 2B is a simplified diagram showing an example of mounting on the lower level of the rack. The rack 150 has a space that can be divided vertically into a total of 46 units. Unit numbers "24 to 46" shown in FIG. 2A are the upper tier. Unit numbers "1 to 23" shown in FIG. 2B are the lower tier. Unit number "20" (FIG. 2B) is equipped with a console (console device) 170 that controls the server 180, and is set at waist to chest height of the user. This improves operability.

[0017] The rack 150 is also provided with eight power taps 161, 162, 163, 164, 165, 166, 167, and 168. The power taps 161, 162, 165, and 166 are arranged on the upper level (FIG. 2A), and the power taps 163, 164, 167, and 168 are arranged on the lower level (FIG. 2B). The power taps 161, 162, 163, and 164 are arranged on the left side, and the power taps 165, 166, 167, and 168 are arranged on the right side. The power taps 161, 163, 165, and 167 are arranged on the front side, and the power taps 162, 164, 166, and 168 are arranged on the back side.

[0018] The power taps are also configured in an Active / Standby configuration for redundancy. An Active / Standby configuration is a configuration in which one device is operating while the other is on standby. Power taps 161, 162, 163, and 164 located on the left side are for Active use (operating), and power taps 165, 166, 167, and 168 located on the right side are for Standby use (standby, spare).

[0019] The "router" installed in unit number "45", the "ONU" installed in unit number "31", and the "console" and "KVM switch" (Keyboard, Video, Mouse switch) installed in unit number "20" (Figure 2B) are connected only to the Active power taps 161, 162, 163, and 164. On the other hand, the "L3 switches" installed in unit numbers "42" and "43," the "L2 switches" installed in unit numbers "39" and "40," the "firewalls" installed in unit numbers "36" and "37," the "servers" installed in unit numbers "17 and 18" (Figure 2B), the "servers" installed in unit numbers "14" and "15," the "FC switches" installed in unit numbers "11" and "12," the "storage" installed in unit numbers "5" to "10," the "storage" installed in unit numbers "3" and "4," and the "storage" installed in unit numbers "1" and "2" are redundant and are connected not only to the active power strips 161, 162, 163, and 164 but also to the standby power strips 165, 166, 167, and 168.

[0020] FIG. 3 is a table showing an example of the device information 200. The device information 200 includes a "Name" column 201, a "Type" column 202, a "Weight (kg)" column 203, a "VA (VA)" column 204, a "Current consumption (A)" column 205, a "Power supply redundancy" column 206, a "Rack mount kit" column 207, an "EOL" column 208, and a "Successor device" column 209.

[0021] The "Name" column 201 lists the device name, such as "AAA" or "BBB." The "Type" column 202 lists the type of device, such as "Storage," "UPS," "Server," or "Network." The "Weight (kg)" column 203 lists the weight of the device. The "VA (VA)" column 204 lists the power consumption of the device (power supply voltage (V) x current consumption (A)). The "Current consumption (A)" column 205 lists the current consumption (A) of the device. The "Power Supply Redundancy" column 206 lists whether an active / standby configuration is adopted. The "Rack Mount Kit" column 207 lists whether hardware for fixing the device to a rack is included. The "EOL" column 208 lists the end of the device's life cycle (yyyy / mm / dd). When the device reaches EOL, maintenance support from the manufacturer will no longer be available. The "successor device" column 209 lists the names of successor devices when replacing devices listed in the "name" column 201. For example, the name of the successor device for a storage device named "AAA" is "RRR."

[0022] FIG. 4 is a table showing an example of the shelf board information 300. The shelf information 300 includes a "Name" column 301, a "Weight (kg)" column 302, and an "Allowable Weight (kg)" column 303. The shelf 190 (FIG. 2A) is a board that separates units of the rack 150 (FIGS. 2A and 2B) and on which equipment is mounted. The "Name" column 301 lists, for example, "aaa," "bbb," ... The "Weight (kg)" column 302 lists the weight (dead weight) of each shelf, for example, "3.0" (kg). The "Allowable Weight (kg)" column 303 lists the maximum weight allowed for equipment placed on each shelf, for example, "80" (kg).

[0023] FIG. 5 is a table showing an example of the rack mounting information 400. The rack mounting information 400 includes a "unit number" column 401, a "name" column 402, a "weight (kg)" column 403, a "VA (VA)" column 404, an "A system circuit 1 (A)" column 405, an "A system circuit 2 (A)" column 406, a "B system circuit 1 (A)" column 407, and a "B system circuit 2 (A)" column 408.

[0024] The "Unit Number" column 401 lists unit numbers "1" to "46." The bottom row of the rack is assigned unit number "1," and the top row is assigned unit number "46." The "Name" column 402 for both unit numbers "1" and "2" is assigned the name "AAA," which is the same as the type "storage" in the device information 200 (FIG. 3). Similarly, the "Name" column 402 for both unit numbers "3" and "4" is assigned the name "BBB," which is the same as the type "storage" (FIG. 3). In other words, the storage with the name "AAA" occupies both unit numbers "1" and "2," and the storage with the name "BBB" occupies both unit numbers "3" and "4."

[0025] Furthermore, the "Name" column 402 for unit numbers "6" and "7" is given the name "CCC," which is the same as the type "UPS" (FIG. 3). Unit number "5" has no name and no device is installed. In other words, there is a predetermined space between the storage named "BBB" and the UPS named "CCC."

[0026] The "Weight (kg)" column 403 lists the weight of the devices installed in each unit. For example, the weight of the storage devices installed in unit numbers "1" and "2" and unit numbers "3" and "4" is "50.0" (kg). The "VA (VA)" column 404 lists the power consumption VA (VA) of the devices installed in each unit. For example, the power consumption VA of the storage devices installed in unit numbers "1" and "2" and unit numbers "3" and "4" is "800.0" (VA).

[0027] As mentioned above, the power strips are configured as Active / Standby, providing redundancy. The A system is configured as Active, and the B system as Standby. The rack is equipped with two circuits for the A system and two circuits for the B system. Circuit 1 refers to the power strip used by the equipment mounted on the upper level of the rack, and Circuit 2 refers to the power strip used by the equipment mounted on the lower level of the rack. In other words, the rack is equipped with a total of four power strips: Circuit 1 / Circuit 2 for the A system and Circuit 1 / Circuit 2 for the B system. For example, the storage devices mounted on unit numbers "1" and "2" use "A system circuit 2" and "B system circuit 2" at "8.0" (A).

[0028] In addition, the "Network" type (Figure 3) named "FFF" and the "Network" type (Figure 3) named "GGG" installed in unit number "25" use "1.0" (A) only in "A system circuit 1" and do not use "B system circuit 1".

[0029] FIG. 6 is a table showing an example of the rack information 500. In a data center or the like, multiple racks are arranged side by side. Each rack is specified with an allowable weight, allowable VA, allowable current of the power strip, etc. That is, the rack information 500 includes a "rack name" column 501, an "allowable weight (kg)" column 502, an "allowable VA (VA)" column 503, an "A system circuit 1 (A)" column 504, an "A system circuit 2 (A)" column 505, a "B system circuit 1 (A)" column 506, a "B system circuit 2 (A)" column 507, a "distance to rack 1 (m)" column 508, a "distance to rack 2 (m)" column 509, etc.

[0030] The "Rack Name" column 501 lists, for example, "Rack 1," "Rack 2," etc. The "Allowable Weight (kg)" column 502 lists the allowable weight (allowable total weight) that limits the total weight of the equipment mounted on each rack. For example, the allowable weight (allowable total weight) of each rack is "400.0" kg. The "Allowable VA (VA)" column 503 lists the allowable power that limits the total power consumption of the equipment mounted on each rack. For example, the allowable VA of each rack is "7000.0" (VA). In other words, when the commercial power voltage is AC 100 (V), the allowable current consumption is 70 (A). Furthermore, the allowable current of the power taps (A system circuit 1, A system circuit 2, B system circuit 1, B system circuit 2) that each rack has is "30.0" (A).

[0031] In the "Distance to rack 1 (m)" column 508, the rack name "Rack 2" is "1.0" (m), the rack name "Rack 3" is "2.0" (m), and the rack name "Rack 4" is "3.0" (m). In other words, the width of each rack is 1 (m).

[0032] 7A and 7B are flowcharts for explaining the operation of the mounting position presentation device when a new additional device is mounted on rack 150 in which existing devices are mounted. First, the weight determination unit 1 (FIG. 1) of the mounting position processing unit 10 determines whether the total weight of the devices exceeds the rack's allowable weight (allowable total weight) (step S101). If the allowable weight (allowable total weight) is not exceeded (Yes in step S101), the mounting position processing unit 10 determines whether the additional device has a rack mount (S102). If the additional device has a rack mount (Yes in step S102), the mounting position processing unit 10 determines whether the additional device is a network device (step S103). If the additional device is a network device (Yes in step S103), the mounting position processing unit 10 determines whether the additional device can be mounted above the existing servers with one or more units of space above or below the existing device or the additional device (step S104).

[0033] If there is no rack mount in S102 (No in step S102), the procedure will be described later with reference to FIG. 7B. If the additional device is not a network device in step S103 (No in step S103), the mounting position processing unit 10 determines whether the additional device is a storage device (step S107). If it is a storage device (Yes in step S107), the mounting position processing unit 10 determines whether the additional device can be mounted below the existing servers with one or more units of space above or below either the existing device or the additional device (step S108).

[0034] If the additional device is not a storage device (No in step S107), the mounting position processing unit 10 determines whether the additional device is a server (step S109). If the additional device is a server (Yes in step S109), the mounting position processing unit 10 determines whether the additional device can be mounted below the existing NW device and above the existing storage device, with one or more units spaced above or below the existing device or the additional device (step S110). On the other hand, if the additional device is not a server (No in step S109), the mounting position processing unit 10 determines whether the additional device can be mounted below the existing server device and above the existing storage device, with one or more units spaced above or below the existing device or the additional device (step S111).

[0035] When it is determined that one or more units can be left empty for installation (Yes in steps S104, S108, S110, and S111), the installation position processing unit 10 determines whether the power determining unit 4 has exceeded the rack's allowable VA (step S105). At the same time, the current determining unit 2 determines whether the current has exceeded the allowable current of the power strip (step S105). When the rack's allowable VA and the allowable current of the power strip are not exceeded (Yes in step S105), the installation position processing unit 10 sequentially checks for available space (empty units) and selects an installation position (step S106). At this time, the installation position processing unit 10 checks for NW devices starting from the top of the rack, storage devices starting from the bottom, servers 180 (FIG. 2B) starting from the top or bottom of the console 170 (FIG. 2B), and UPSs starting from the top of the storage devices. Note that NW devices are installed at the top of the rack in order to connect LAN cables to other devices.

[0036] Furthermore, when repairing or replacing equipment during maintenance work, etc., it is desirable to provide a predetermined space above or below the equipment. Therefore, the equipment is mounted with one or more units (for example, 1, 2, 3, or 4 units) spaced above or below it. In other words, a predetermined space is provided between the equipment to be mounted on the rack and the existing equipment already mounted on the rack. After the processing of step S106, the processing ends.

[0037] On the other hand, when the total weight of the equipment exceeds the allowable weight of the rack (No in S101), when it is determined that the equipment cannot be mounted with one or more units spaced apart (No in steps S104, S108, S110, and S111), or when the allowable VA of the rack and the allowable current of the power tap are exceeded (No in step S105), the mounting position processing unit 10 changes the object of judgment to another rack that is closer (step S112), and returns the processing to step S101.

[0038] Meanwhile, if the additional device does not have a rack mount (No in step S102), the mounting position processing unit 10 determines whether or not there is a shelf on the rack (step S201 (FIG. 7B)). If there is an existing shelf (existing shelf) (Yes in step S201), the mounting position processing unit 10 determines whether or not the weight of the additional device exceeds the allowable weight of the shelf (existing shelf) (step S202). If the allowable weight is not exceeded (Yes in step S202), the mounting position processing unit 10 determines the mounting position of the additional device on the existing shelf (step S203), and the process ends.

[0039] If the rack does not have a shelf (No in step S201) or if the weight exceeds the shelf's allowable weight (No in step S202), the mounting position processing unit 10 determines whether a shelf can be added to the rack (step S204). If a shelf can be added (Yes in step S204), the mounting position processing unit 10 determines whether the total weight of the additional replacement device and the additional shelf exceeds the rack's allowable weight (step S205). If the total weight does not exceed the rack's allowable weight (Yes in step S205), the mounting position processing unit 10 determines whether the additional replacement device can be installed above the existing server with at least one unit of space above or below the existing device, the additional replacement device, or the additional shelf (step S206). If the additional replacement device can be installed with at least one unit of space (Yes in step S206), the mounting position processing unit 10 checks the available space from the top of the rack, determining the mounting positions of the additional replacement device and the additional shelf (step S207), and the process ends.

[0040] On the other hand, if a shelf cannot be added to the rack (No in step S204), if the weight exceeds the rack's allowable weight (No in step S205), or if the rack cannot be mounted with one or more units spaced apart (No in step S206), the mounting position processing unit 10 changes the target of judgment to another rack that is closer (step S208). After processing step S208, the mounting position processing unit 10 returns the process to step S201 and repeats the judgment of whether or not there is a shelf in the rack whose target of judgment has been changed (step S201).

[0041] 8A and 8B are flowcharts for explaining the operation of the mounting position presentation device when replacing an existing device (for example, an EOL device) mounted on the rack 150 with a new device (a successor device). Steps S301 to S305 and steps S307 to S312 in Fig. 8A are the same as steps S101 to S104 and steps S107 to S112 in Fig. 7A. Steps S401 to S408 in Fig. 8B are the same as steps S201 to S208 in Fig. 7B. However, they differ in that "additional device" has been changed to "successor device."

[0042] If the allowable VA of the rack and the allowable current of the power strip are not exceeded (Yes in step S305), the mounting position processing unit 10 checks for available space (empty units) above or below the number of units in which the EOL devices are mounted, and selects a mounting position (step S306). At this point, it is necessary to transition from the EOL device to a successor device, and the successor device must also be connected to a cable connected to the existing device that is connected to the EOL device by cable. Therefore, the successor device is mounted near the EOL device. After step S306 is completed, the processing ends.

[0043] (Explanation of effect) According to the installation position presentation device 100 of this embodiment, when a new device (additional device) is added to a rack 150 in which a device (existing device) is installed, or when an existing device approaching EOL is replaced with a successor device, the installation position presentation device 100 presents the installation position (unit number of the rack 150) for installing the additional device or successor device in the rack 150, and displays the presentation result on the operation display unit 70 ( FIG. 1 ). At this time, the installation position presentation device 100 checks the allowable weight (kg) and allowable power (VA) of each rack, the allowable current (A) of the power strip, the total weight (kg) of the existing devices, the total power consumption (VA), the current consumption (A) of the existing devices, and EOL information. This allows the user to determine the installation position for the additional device or successor device in the rack. In other words, the user can reduce the effort required to determine the installation position.

[0044] Furthermore, the rack configuration allows for easy maintenance work by workers, making it easy to handle equipment and cables. Furthermore, at a time determined by the user, the EOL equipment notification unit 40 (Fig. 1) notifies the user of the equipment whose system is approaching EOL and its successor equipment. This allows the user to quickly determine when to purchase and replace the successor equipment.

[0045] (Variation) The present invention is not limited to the above-described embodiment, and various modifications are possible, for example, as follows. (1) In the above embodiment, when replacing an existing device installed in the rack 150 (FIGS. 2A and 2B) with a successor device, it is assumed that the successor device will be installed in the position where the existing device was removed. When switching the settings of a server or the like from the existing device to a successor device, it is preferable to arrange the existing device and the successor device within a predetermined distance (specifically, a distance shorter than the cable length). That is, it is preferable that the installation position presenting unit 3 (FIG. 1) presents the new installation position of the existing device (including the original installation position) and the installation position of the successor device (including the original installation position of the existing device) so that the distance between the existing device and the successor device is within the predetermined distance. In this case, it is preferable that the installation position presenting unit 3 (FIG. 1) presents installation positions that allow the existing device and the successor device to be installed side by side (including not only left-right but also top-bottom side by side). Note that after switching the settings of the server or the like, the existing device is removed from the rack 150, completing the replacement work with the successor device.

[0046] (2) In the above embodiment, the current consumption of the existing devices is obtained from the device information 200 (FIG. 3). However, a current measuring device may be provided to measure the current consumption of the existing devices. This current measuring device may measure the current consumption constantly, or may measure it temporarily when adding or replacing devices.

[0047] (3) The mounting position presentation device 100 in the above embodiment is intended to mount network devices, servers, storage devices, and power supply devices including UPS in a rack. It is also possible to mount other devices such as power supply devices and displays, and cabinets for storing device parts in a rack. Furthermore, the structures of the air intake and exhaust ports vary depending on the equipment, with some taking in air at the front and exhausting at the rear, and others taking in air at the rear and exhausting at the front. In this case, it is preferable to add information about the position of the equipment's air intake and exhaust ports to the equipment information 200 (Fig. 3) and the direction of the air conditioning for each rack to the rack information 500 (Fig. 6). This information can be used when determining the optimal installation position and orientation of the equipment. [Explanation of symbols]
