Storage system and power consumption reduction method for the same
First Claim
1. A storage system, comprising:
- at least one storage apparatus that includes a first power control mechanism;
at least one computer that includes a controller for storing a file in the storage apparatus, a second power control mechanism and a virtual file server that issues start, stop and failover commands; and
a power management computer that controls the first power control mechanism and the second power control mechanism,wherein the power management computer includes a first shift controller that;
refers to a load on the computer;
stops the virtual file server or performs failover for the virtual file server when the load is low; and
shifts the states of the first power control mechanism in the storage apparatus and the second power control mechanism in the computer to a power-off state or a low power consumption state.

Abstract
In a storage system that includes two or more file servers each including an arbitrary number of operating virtual file servers, a management server: holds a load information table regarding a load on each virtual file server for each time period and redundancy information table for the storage system; judges, with reference to the load information table and redundancy information table, whether or not the loads on the virtual file servers can be handled by a smaller number of file servers than the number of currently-operating file servers; selects, if the judgment result is positive, a power-off target file server and makes another file server fail over a virtual file server in the power-off target file server; and turns off the power-off target file server.

17. A power consumption reduction method for a storage system that includes:
- at least one storage apparatus including a first power control mechanism;
at least one computer including a controller for storing a file in the storage apparatus, a second power control mechanism and a virtual file server for issuing start, stop and failover commands; and
a power management computer that controls the first power management mechanism and the second power management mechanism, the method comprising steps performed by the power management computer, the steps being;referring to a load on the computer; and stopping the virtual file server or performing failover for the virtual file server when the load is low, and shifting the states of the first power control mechanism in the storage apparatus and the second power control mechanism in the computer to a power-off state or a low power consumption state. - View Dependent Claims (18, 19)
