Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0060] Such as figure 1 As shown, the present invention includes: an initialization step, a load detection step, a load statistics step, a judgment migration condition step, an object data block migration step and a read and write request scheduling step.

[0061] The load detection step cyclically detects the load of the system, and stores the load information of the system in the device load table; the load statistics step obtains the load information of the device through the device load table, and then groups the devices according to the available capacity of the device and stores them in the disk group table, and then sort the storage devices in the disk group table; the step of judging the migration conditions uses the equipment load table to obtain the capacity utilization ascending list to judge the migration conditions, and then obtain the migr...

Abstract

A scheduling method for read-write requests of an object data server belongs to the field of computer storage, resolves the problem that self-carried software of an existing Linux system cannot guarantee load balance of storage equipment, and further improves usability and performance of the object data server. The scheduling method comprises an initialization step, a load detection step, a load statistics step, a transition condition judgment step, an object data block transition step and a read-write request scheduling step. The load balance among the multiple devices is realized by request scheduling among multiple devices, parallelism of multiple devices and data transition, and usability and performance of the storage system are improved. The scheduling method is low in cost for achieving disk arrays on a software layer, has excellent advantages compared with heterogeneous storage equipment, simultaneously can use storage equipment of a framework of a network attached system (NAS), and improves expandability.

Description

technical field [0001] The invention belongs to the field of computer storage, and in particular relates to a scheduling method for reading and writing requests of an object data server. Background technique [0002] With the increase of Internet business volume, the rapid growth of access volume and data flow, the processing intensity of each core part of the storage system has also increased correspondingly, making it impossible for a single storage device to bear it. In this case, if you throw away the existing equipment and do a lot of hardware upgrades, it will inevitably cause a waste of existing resources, and facing the next increase in business volume, it will lead to another high cost investment in hardware upgrades. No matter how excellent the equipment is, it cannot meet the current traffic requirements. Therefore, the current storage system needs to face heterogeneous storage devices with different performance and capacity. [0003] In the object storage syste...
