Abstract
An information processing system includes a plurality of servers stored in a first rack; and a management server coupled to the plurality of servers and configured to: acquire consumed power values from the plurality of servers when power is supplied to the plurality of servers via first power supply lines coupled to a first power strip of the first rack, calculate the total of the consumed power values based on the values of power consumed by the plurality of servers, and switch a power supply of at least one servers among the plurality of servers so that power is supplied to the at least one server via a second power supply line coupled to a second power strip of a second rack when the total of the consumed power values exceeds a first threshold.
Claims9
An information processing system, comprising:
- a plurality of servers respectively stored in one of a plurality of racks;
- and a management server coupled to the plurality of servers and configured to:
- acquire consumed power values from the plurality of servers when power is supplied to the plurality of servers,
- calculate a total value of the acquired consumed power values for each of the plurality of racks, and
- determine whether a first rack of which total consumed power value has exceeded a first threshold exists among the plurality of racks,
- determine whether a second rack of which total consumed power value is equal to or smaller than a second threshold exists among the plurality of racks when it is determined that the first rack of which total consumed power value has exceeded the first threshold exists,
- switch a power supply line of the first rack such that power is supplied from a power strip of the second rack to either of one or more target servers stored in the first rack until the total consumed power value of the first rack becomes equal to or smaller than a third threshold which is smaller than the first threshold when it is determined that the second rack of which total consumed power value is equal to or smaller than the second threshold exists, and
- switch a power supply of any of servers that are among the plurality of servers and of which values of consumed power are smaller than a value obtained by subtracting difference between the first and third thresholds from the third threshold.
A control method executed by a processor included in a management server coupled to a plurality of servers stored in a first rack, the control method comprising:
- acquiring consumed power values from the plurality of servers when power is supplied to the plurality of servers;
- calculating a total value of the acquired consumed power values for each of a plurality of racks;
- determining whether the first rack of which total consumed power value has exceeded a first threshold exists among the plurality of racks;
- determining whether a second rack of which total consumed power value is equal to or smaller than a second threshold exists among the plurality of racks when it is determined that the first rack of which total consumed power value has exceeded the first threshold exists;
- switching a power supply line of the first rack such that power is supplied from a power strip of the second rack to either of one or more target servers stored in the first rack until the total consumed power value of the first rack becomes equal to or smaller than a third threshold which is smaller than the first threshold when it is determined that the second rack of which total consumed power value is equal to or smaller than the second threshold exists:
- and
- switching a power supply of any of servers that are among the plurality of servers and of which values of consumed power are smaller than a value obtained by subtracting difference between the first and third thresholds from the third threshold.
A management server coupled to a plurality of servers stored in a first rack, the management server comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- acquire consumed power values from the plurality of servers when power is supplied to the plurality of servers,
- calculate a total value of the acquired consumed power values for each of a plurality of racks, and
- determine whether the first rack of which total consumed power value has exceeded a first threshold exists among the plurality of racks,
- determine whether a second rack of which total consumed power value is equal to or smaller than a second threshold exists among the plurality of racks when it is determined that the first rack of which total consumed power value has exceeded the first threshold exists,
- switch a power supply line of the first rack such that power is supplied from a power strip of the second rack to either of one or more target servers stored in the first rack until the total consumed power value of the first rack becomes equal to or smaller than a third threshold which is smaller than the first threshold when it is determined that the second rack of which total consumed power value is equal to or smaller than the second threshold exists, and
- switch a power supply of any of servers that are among the plurality of servers and of which values of consumed power are smaller than a value obtained by subtracting difference between the first and third thresholds from the third threshold.
