Software-defined storage performance evaluation method

Abstract

The invention discloses a software-defined storage performance evaluation method. The method comprises the steps of (1) establishing a hardware environment; (2) establishing a basic hardware performance baseline; (3) deploying storage software; (4) preliminarily testing performance indexes; (5) optimizing a configuration capability of the storage software; (6) retesting the performance indexes; and (7) evaluating the performance indexes, and after the evaluation process is ended, taking a physical performance baseline exertion percentage as an index in an evaluation result, wherein the index covers contents such as bandwidth, time delay, IOPS, concurrent capability and the like. The invention discloses the performance evaluation method for software-defined storage in type selection of a basic framework of an information system; and the method is distinguished from a mode with the help of hard indexes such as IOPS, capacity, scale and the like in a current performance evaluation process, pays more attention to an extraction capability of software to existing hardware performance, and better conforms to reality of software-defined storage enterprise application.

Description

technical field [0001] The invention relates to a software-defined storage performance evaluation method. Background technique [0002] Software-defined storage (SDS) is a data storage method in which all storage-related control work is only in external software relative to the physical storage hardware. This software is not as firmware in a storage device, but on a server or as part of an operating system (OS) or hypervisor. [0003] Software-defined storage is a larger industry development trend, which also includes software-defined networking (SDN) and software-defined data center (SDDC). Similar to the case of SDN, software-defined storage can ensure that the system's storage access can be managed more flexibly at a precise level. Software-defined storage is abstracted from hardware storage, which also means that it can be turned into a shared pool that is not limited by the physical system for the most efficient use of resources. It can also be deployed and provision...

Problems solved by technology

[0004] As an emerging technology form, software-defined storage has gradually been popularized and applied with the rise of "Internet +", but there is a lack of corresponding performance evaluation technology

The traditional centralized storage evaluation method has been used for a long time, mainly based on hardware IOPS, capacity and expansion capabilities, ignoring the embodiment of "soft capabilities" in software-defined storage; on the other hand, because software-defined storage-related products have relatively Strong scalability, the performance index obtained by the traditional evaluation method is seriously out of line with the production capacity, and a new evaluation method is urgently needed to objectively evaluate the performance level of software-defined storage products
