Example Embodiment

[0029] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] Such as figure 1 As shown, it is a schematic diagram of the flow of a hierarchical storage energy saving method according to an embodiment of the present invention. The hierarchical storage method of the present invention includes the following steps:

[0031] Step S1: Automatic storage classification.

[0032] When the cluster is started, the host name is used to identify the storage layer of each host containing the storage layer, and the nodes with lower storage layers are adjusted to the energy-saving mode according to the ratio. Automatically identify the access performance of each node. In this embodiment, 40% of the secondary storage tier and 60% of the tertiary storage tier are adjusted to the energy-saving mode; of course, in other embodiments, the number of storage tiers and the ratio of the adjustment to the energy-saving mode can be ...

Abstract

The invention discloses a classification storage energy-saving method. The classification storage energy-saving method comprises the following steps: automatic classification of storage, namely, staring a cluster, automatically recognizing the storage level which each host machine is in, and regulating the node point in a lower storage level into an energy-saving mode according to the proportion; directional access, namely, selecting the storage level which is short in distance and high in storage level to store and read documents; and searching of thermal date, namely, recoding access information of each data block in the documents, obtaining the value of each access data block according to the recorded information and forming a queen according the value in a mode of from high to low. The classification storage energy-saving method guarantees the energy conservation effect of the cluster.

Description

technical field [0001] The invention relates to a storage technology in the computer field, in particular to a hierarchical storage energy-saving method. Background technique [0002] With the explosive growth of data volume, server clusters for storing and processing massive amounts of data are becoming more and more common. The energy consumption of these server clusters has attracted more and more attention. [0003] According to statistics, in the cost of building a server cluster, only the power consumption of servers and cooling systems accounts for 20%, while most servers are in a low-load state most of the time, generally not higher than 30%, resulting in a large waste of electricity. In order to try our best to reduce the unnecessary loss caused by this kind of power waste, cluster energy-saving technology came into being. [0004] The key point of the current cluster energy-saving technology is to concentrate the tasks in the cluster to run on individual servers...
