By adjusting the power consumption level of each object-based storage server according to the actual utilization rate and service queue condition thereof, the invention can meet the requirements of the object-based storage server for the control of power consumption; and by using the metadata server to handle the service request and make the specific service request, the invention can improve the efficiency of the control of power consumption.
Description
Technical field
The present invention relates to the power consumption control method of computer system, refer to power consumption control method especially based on object storage system.
Background technology
Parallel memory system is the important component part in the massively parallel computer system, and object storage system is a kind of parallel storage organization.As shown in Figure 1, object storage system is made of by network interconnection a meta data server, a plurality of object storage server and a plurality of calculating node.Meta data server and a plurality of object storage server provide file access services such as reading and writing data, data storage for calculating node.Meta data server provides the metadata service for calculating node, is that object storage system is peculiar.The owner of each file of metadata description, creation-time, modification time, file size and the file information such as distribution on object storage system.The object storage server is responsible for preserving the concrete data of file, and provides the file access service to calculating node under the management of meta data server.Calculate the file access request of node and at first submit to meta data server, obtain file distribution information, submit request of access according to distributed intelligence to relevant object storage server then, finish the reading and writing data process.Object storage system makes full use of the concurrency of high bandwidth network and memory access, for parallel the application provides the higher data access bandwidth, has been widely used in the computer system of World super computing machine rank preceding ten.Power consumption is the major issue in the massively parallel computer system design, and the power consumption of storage system accounts for significant proportion.Along with the widespread use of object storage system, carry out the power consumption that power consumption control helps to reduce whole concurrent computational system based on object storage system.
Power consumption control method at storage system has at present: (1) is set to dormant state with temporary transient obsolete memory device (for example disk), reduces the power consumption of memory device; (2) rotating speed of adjustment disk unit, the power consumption of reduction memory device; (3) optimize data access, improve the data access hit rate, reduce disk tracking and number of revolutions; (4), there be not under the data backup task situation power consumption level be set as minimum with backup server at data center such as backup server; Or the like.At the power consumption control method (as preceding two kinds of methods) of equipment and the data-optimized method that reduces disk tracking number of times, can not obtain the situation of change of services request in the storage system, can not carry out effective power consumption control according to application characteristic.Considered the busy-idle condition of server at the power consumption control method (as the 4th kind of method) of data center's backup server, implemented simple optimised power consumption, but this method can not be carried out the power consumption control under the services request situation complicated in the object storage system.Also there is not public technology data at present at the power consumption control method of object storage system.
Summary of the invention
