Description

A method for testing basic energy consumption of a storage system

technical field

The present invention relates to the field of computer technology, in particular to a method for testing basic energy consumption of a storage system.

Background technique

With the rapid development of computer applications and network technologies, the energy consumption of storage systems in applications has become more complex and larger. For the energy consumption test of the storage system, the industry currently mainly uses two types:

1. SPEC Power_ssj2008 of SPEC

SPECpower_ssj2008 is the first industry standard for evaluating server performance and energy consumption characteristics of the SPEC benchmark test, released by the SPEC committee. The latest version is V1.1, which was released on April 15, 2009. This evaluation method points out that the energy consumption will be affected by conditions such as load, test environment and usage parameters, but it is mainly designed for servers.

2. SNIA's Green Storage Power Measurement Benchmark

Green Storage Power Measurement Benchmark is released by SNIA. Since April 2008, it has been revised 4 times to the current version 0.0.18, which is still in the draft stage. This evaluation method draws on SPECpower_ssj2008. The current standard only considers the energy consumption in the idle state, and only proposes a capacity-per-power idle state measurement index.

The initial design concept of these two test methods is aimed at server applications, and only considers a situation of energy consumption test in idle state, and the measurement indicators of the test results are relatively single, which is too simple. Moreover, the IO load does not directly face the storage, and the test indicators are not reasonable. With the increasingly widespread application of storage systems and the promotion of the concept of green energy saving, it is necessary to propose a set of targeted and relatively complete energy consumption test system for storage systems.

Contents of the invention

The purpose of the present invention is to provide a method for testing basic energy consumption of a storage system.

The purpose of the present invention is achieved in the following manner, in order to fully reflect the energy consumption of the storage system, the energy consumption of the storage system is divided into three parts for testing: disk array, switching equipment and server, wherein:

The disk array energy consumption test indicators in the storage system include: IO load-related energy consumption change rate, resource-related energy consumption change rate, unit capacity power consumption rate and energy consumption utilization rate;

The energy consumption test indicators of switching devices in the storage system include: power consumption in idle state and power consumption in full load state;

The server energy consumption test indicators in the storage system include: unit energy consumption, IO load-related energy consumption change rate and SPECPower_ssj2008 index test;

The test steps are as follows: use the combination of software and hardware to build a test system, the software system controls the load combination required for the test, obtain data from hardware tools and finally calculate the various energy consumption indicators of the storage system, and the basic energy consumption test of the storage system includes the test of a single indicator Or combine and test different energy consumption side indicators of the feedback system.

The beneficial effects of the present invention are: the energy consumption test of the storage system is divided into three main parts: disk array, network equipment and server, and each part has clear test indicators and different test methods. According to this method, energy consumption problems of any storage system can be conveniently compared, and the method is simple and easy to implement, and the method can be extended. Each energy consumption index set can not only represent certain parameters independently, but also can be properly combined to feed back different aspects of energy consumption of the storage system.

Detailed ways

With reference to accompanying drawing of description, method of the present invention is described in detail below.

The energy consumption test of the storage system mainly examines two aspects of power consumption and heat loss. The goal is to evaluate the absolute energy consumption and relative energy consumption parameters of the storage system, that is, the actual consumption and energy utilization rate of the system. The main indicators of energy consumption evaluation are as follows:

1. Basic energy consumption indicators

1) IO load-related energy consumption change rate

When the IO load of the storage system changes per unit time, the system energy consumption trend;

2) Change rate of resource-related energy consumption

When the configuration ratio of various resources in the storage system changes, the system energy consumption change trend;

3) Energy consumption rate per unit capacity

Refers to the power required by the storage resources of the unit capacity of the disk array;

4) Energy utilization

The proportional relationship between power consumption and heat loss;

2. Energy consumption indicators for typical applications

overall energy consumption. Investigate the energy consumption per unit time of a network storage system as a whole under the normal operation of a specified application.

A large storage system generally consists of three parts: servers, network devices, and disk arrays. Among them, the disk array is the final carrier of data, the network device is the internal interconnection channel of the storage system, and the server is the management and external service interface in the storage system. For these three main parts, the detailed classification of the basic energy consumption test is established as shown in Figure 1.

The basic energy consumption test system of the storage system is constructed by combining software and hardware. The software system controls the load combination required for the test, obtains data from hardware tools, and finally calculates various energy consumption indicators of the storage system. Figure 2 shows the schematic diagram of the topology.

Table 1 is a detailed definition of the basic energy consumption test in the storage system, including the test indicators under different system component indicators, and the calculation method and dimension of each indicator. The storage system evaluation system is a unified whole, including both the vertical hierarchical relationship and the parallel relationship between indicators. Different indicators reflect different aspects of the storage system and belong to different categories. Therefore, different storage systems can be tested for individual indicators or combined tests to feed back the different energy consumption aspects of the system.

The detailed definition of the basic energy consumption test of the storage system is shown in the table below

Note: ↑ indicates that the larger the value is, the better the system is, and ↓ indicates that the smaller the value is, the better the system is

Each energy consumption index set in Table 1 can not only represent certain parameters independently, but also can be properly combined to feed back different aspects of energy consumption of the storage system.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
