Abstract
The invention provides a cluster storage system expansion method based on an identical expansion module. The system comprises an expansion module, wherein the expansion module consists of a performance module and a capacity module; the performance module comprises bandwidth or input/output operations per second (IOPS), is hardware similar to a gateway or a controller and is used for improving the performance of a cluster storage system; and the capacity module is used for improving the capacity of the system, is a hard disk or just a bunch of disks (JBOD) hardware equipment and is used for expanding the capacity of the system, so that a larger storage space is established, and more data is saved. The cluster storage system expansion method comprises the following expansion steps that: the expansion module determines a reasonable ratio of the performance to the capacity according to different cluster storage application, the ratio is kept invariable, an expansion module is formed, and the identical expansion module is expanded during expansion every time, so that the balanced performance and capacity of the whole system are guaranteed.
Description
Technical field
The present invention relates to cluster storage system, specifically a kind of cluster storage system extended method based on identical expansion module.
Background technology
At present, expansion generally speaking, unordered or random scalability module or capacity module cause system performance and capacity not to mate, and can't reach good equilibrium, cause system adjustment and optimization complicated, can't obtain balanced performance performance.
Summary of the invention
The purpose of this invention is to provide a kind of cluster storage system extended method based on identical expansion module.
The objective of the invention is to realize in the following manner, system comprises: expansion module, and wherein expansion module is that do as one likes energy module, capacity module form, wherein:
Performance module: being used for promoting the performance of cluster storage system, comprising bandwidth or IOPS, is the hardware of similar gateway or controller and so on, improves the performance of system by increasing this kind equipment;
Capacity module: be used for improving the capacity of system, along with the increase of system data, often need the capacity of expanding system, to store more data, the capacity module is hard disk or JBOD hardware device, is used for the capacity of expanding system, to create larger storage space, preserve more data;
Expansion module, do as one likes energy module and capacity module form, use according to different cluster storages, determine a rational ratio of performance and capacity, performance module and capacity module are bound together according to this ratio, keep this constant rate, become an expansion module, same expansion module is all expanded in each expansion, to guarantee performance and the capacity equilibrium of whole system;
The invention has the beneficial effects as follows: the expansion module by customization has kept the equilibrium of capacity and performance, thereby has guaranteed the performance of whole system and the equilibrium of capacity.Simultaneously, also be convenient to fault diagnosis and the Performance Prediction of system, can realize knowing what's what, for which type of demand, just can be easy to definite quantity of wanting the equipment of dilatation.Simultaneously, also can conveniently dispose.
Description of drawings
Fig. 1 is without the cluster storage system structural drawing of customized extension module;
The cluster storage system structural drawing of Fig. 2 customized extension module.
Embodiment
Explain below with reference to Figure of description method of the present invention being done.
The invention provides a kind of based on identical expansion module the cluster storage system extended method.This system adapts to framework and the expansion demand of cluster storage system, design the expansion module that a kind of capacity and performance are complementary, thereby guaranteed that group system in expansion, keeps the equilibrium state of a kind of performance and capacity, avoided occurring the unbalanced situation of capacity and performance.
System comprises three large module groups: performance module, capacity module and expansion module.Performance module be used for to promote the performance of cluster storage system, such as bandwidth, and IOPS etc., the hardware of normally similar gateway or controller and so on improves the performance of system by increasing this kind equipment.
The capacity module is used for improving the capacity of system, along with the increase of system data, often needs the capacity of expanding system, to store more data.The capacity module is hard disk normally, or the hardware device such as JBOD, is used for the capacity of expanding system, to create larger storage space, preserves more data.
Spread step is as follows: use according to different cluster storages, determine a rational ratio of performance and capacity, performance module and capacity module are bound together according to this ratio, keep this constant rate, become an expansion module.Same expansion module is all expanded in each expansion, to guarantee performance and the capacity equilibrium of whole system.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
