Description

  The present invention is a technique for monitoring a power supply when power is supplied to a power supply apparatus redundant in a server in a computer system using an uninterruptible power supply (UPS).

  Computer systems are required to have high reliability and availability of servers constituting the system. In general, in addition to the redundant configuration of components such as the CPU, memory device, and main storage device in the server, the power supply of the server is considered in consideration of the power supply redundancy and the power failure of the facility where the server is installed. A method of supplying power by connecting an uninterruptible power supply (UPS) to the apparatus is used.

  By the way, when the power supply of the server is made redundant and the uninterruptible power supply (UPS) is used, the power supply from the uninterruptible power supply (UPS) is constantly monitored. Control is performed so that the entire computer system including the operating system in the server is not stopped by supplying power from the battery in (UPS). For example, Japanese Patent Laid-Open No. 2006-254688 discloses that the power supply of the uninterruptible power supply (UPS) is constantly monitored before a power failure occurs for a certain period of time and power supply to the server by a battery becomes impossible. A control method for safely stopping (shutting down) a server operating system is disclosed.

The operating system control process is predicted to be unable to supply power from the uninterruptible power supply (UPS) battery, and the power supply to the power supply directly connected to the power outlet is normally supplied. In such a case, it is predicted that the operating system will be continuously operated, and the power supply by the battery of the uninterruptible power supply (UPS) will be impossible, and the power supply to the power supply apparatus directly connected to the power outlet will be supplied. If not, shut down the operating system safely.

The present invention predicts that power cannot be supplied by a battery of an uninterruptible power supply (UPS), and if power supply to a power supply directly connected to a power outlet is normally supplied, When the system is operated continuously, and it is predicted that the power supply by the battery of the uninterruptible power supply (UPS) cannot be continued, and the power supply to the power supply directly connected to the power outlet is not supplied An object of the present invention is to provide a technique for safely shutting down an operating system.

  One means for solving the above problem will be described. A redundant power supply monitoring system according to the present invention includes a plurality of power supply devices and transmission / reception means for notifying the server of power supply information from uninterruptible power supply devices connected to the server, and an uninterruptible power supply for storing the power supply information.

S), connect the uninterruptible power supply (UPS) and the distribution board using a power outlet,
The other power supply is connected directly to the power outlet, and the power outlet and the distribution board are connected. Therefore, it is predicted that the power supply from the battery of the uninterruptible power supply (UPS) will be impossible, and directly When the power supply to the power supply device connected to the power outlet is normally supplied, the operating system can be continuously operated.

In addition, if it is predicted that the power supply by the battery of the uninterruptible power supply (UPS) cannot be continued, and the power supply to the power supply apparatus directly connected to the power outlet is not supplied, the operating system is safely stopped ( Can be shut down).

  FIG. 6 is a flowchart showing information processing according to the first embodiment of the present invention.

  First, management data 1051 and management data 1031 respectively stored in the PS information management unit 105 and the power information reading unit 103 are monitored in real time (S101).

  The power monitoring control unit 106 detects that the power supply has been cut off due to a power failure (S1011). When the power supply is cut off, the UPS input unit voltage 10512 and the UPS input unit current 10513 of the management data 1051 of the UPS information management unit 105 become zero, so the part where the power supply is cut off is the input of the uninterruptible power supply 110. It is determined that it is the unit 111 (S102).

  When the power supply is interrupted due to the failure of the uninterruptible power supply 110, the UPS output unit voltage 10514 and the UPS output unit current 10515 of the management data 1051 of the UPS information management unit 105 become zero. When the remaining battery capacity 10516 becomes zero and the power supply is cut off, it is determined that the part where the power supply is cut off is the output unit 115 of the uninterruptible power supply 110 (S103). As a result of the determination, if it is the output unit 115, the process of S105 is performed. When the determined result is not the output unit 115, the process of S107 is performed.

  In S102, when the part of the power supply device whose power supply is cut off is the input unit 111 of the uninterruptible power supply 110, the power supply from the battery 112 is automatically performed by the function of the uninterruptible power supply 110, and the remaining battery capacity The amount of power that can be supplied to the server 100 is obtained by dividing the consumption amount of the remaining battery capacity 10516 by the amount of power consumed by the server 100 from the amount of power stored in 10516 and the amount of power consumed by the server 100. (S104). When the part of the power supply device whose power supply is cut off is the output unit 115 of the uninterruptible power supply 110, the power supply device of the management data 1051 of the UPS information management unit 105 is changed from the management data 1031 stored in the power information reading unit 103. It is determined whether the input unit voltage 10312 and the input unit current 10313 of the power supply device ID 10311 different from the ID 10511 are zero (S105).

  In S103 and S105, if neither of the redundant power supply devices is supplied with power, the operating system abnormally stops (S107).

  In S105, when power is supplied to the power supply apparatus that is not connected to the uninterruptible power supply apparatus 110, the operating system is continuously operated (S108). Also, real-time monitoring is performed (S101).

  In S104, the time for which power can be supplied is predicted from the remaining battery capacity 10516 of the uninterruptible power supply 110 and the power consumption of the server, and the time for which power can be supplied is required for the shutdown process of the operating system 107 of the server 100. When it is determined that the time is shorter than about 3 minutes, the input unit voltage 10312 and the input unit current 10313 of the power unit ID different from the power unit ID of the management data 1051 of the UPS information management unit 105 are obtained from the management data 1031. Check to see if it is zero (S106). If it is determined in S106 that the input unit voltage 10312 and the input unit current 10313 are zero, a shutdown process is performed to normally stop the operating system 107 (S109). If it is determined in S106 that the input unit voltage 10312 and the input unit current 10313 are not zero, the operating system is continuously operated S108. Also, real-time monitoring is performed (S101).
