Description

Structure is based on the method and apparatus of the simulator of the equipment of storage management plan specification

Technical field

The present invention relates to computer realm, more specifically relate to a kind of be configured to store and test that network device management is used, based on the method and system of the simulator of the equipment of storage management plan specification (SMI-S).

Background technology

Common information model (CIM) by distributed management task groups (DMTF) exploitation is a kind of standard mode that is used to describe about the data of application and equipment, it makes keeper and software manager can control application and the equipment on the different platform in the same manner, has guaranteed in the whole network interoperability on the Internet for example.Because the common architecture of CIM, it has been widely used in managing in the management software of the various types of storages and the network equipment.

The SMI-S of storage networking industry association (snia) uses CIM as implementation model.SMI-S has defined the actuating logic process of the standard class, attribute, method and the method that are used for memory device.SMI-S allows foreign peoples's storage environment is carried out the management of simple, standardized and cost-effective.It allows the IT supvr to use the software of OEM to manage third-party storage products, or opposite.In addition, SMI-S provides public, interoperable and extendible management transmission mechanism, and irrelevant with manufacturer.Object model that is complete, unified and that strictly regulate provides the control to the logical unit number in storage area network (SAN) environment and memory block (zone) etc.SMI-S also comprises an automatic discovery system.By reducing the necessity of management special purpose interface, SMI-S will produce a very large impact total cost that has.

In CIM realizes, CIM Object Manager (CIMOM) management object among the CIM agency, these objects will be managed between CIM agency and CIM client by the CIM agreement.In typical storage management software architecture based on CIM, the CIM agency is what to be realized in the hardware device of low layer, and CIM client realizes in the management software of high level.For the storage management software of the higher level of developing the storage that can manage a lot of foreign peoples and the network equipment, for example have the control desk of graphic user interface, wish that each equipment of being managed all realizes a CIM agency.By this way, high layer software can be by the interface connection with it of CIM agreement.Therefore, low-level hardware and CIM agency is relied on by top management software.In addition, if equipment is supported the SMI-S standard, then equipment should provide SMI-S interface by the CIM agency.

Fig. 1 shows the architecture of the equipment control control desk that uses CIM.Wherein, CIMOM handles and communicates by letter and the CIM-XML coding/decoding with CIM client's HTTP (S).It is responsible for CIM pattern (schema) operation, and example and method request are transmitted to corresponding service provider (being that CIM provides device).Provide the device interface to handle CIMOM and communication between the device is provided.What all main CIMOM had defined oneself provides the device native interface.Service provider is for each equipment development and be registered in service routine among the CIMOM.It is called with operating equipment by CIMOM, and it is responsible for handling all example request, realizes externalist methodology and indication (indication) processing.

In order to realize being used for the storage management software of a lot of universal storage devices, the interface of testing these equipment is absolutely necessary.And, use for development management, importantly test fully.Yet it is difficult testing fully on real equipment and CIM agency who is realized and SMI-S service provider.Problem is: hardware is always very expensive, always hinders everyone work and share limited hardware between many people; Not enough hardware resource also can cause constraint to test more completely, for example, and when attempting to use 4 looping tests volumes to create, and when three dishes are only arranged.When carrying out pressure test, 100 dishes then more are difficult to realize if desired.

Therefore, setting up certain simulator environment, to carry out more effective test be very important.The simulator of the common apparatus by having CIM agency and SMI-S service provider can need not to use real memory device and tests top management software.

Although SMI-S has defined the standard procedure of handling any request and method, different service providers also can define will be by the specific class and the attribute of tension management application access.Therefore, some present solutions are to be the different different simulators of equipment development independently.Specifically, in the prior art,, need manually write simulator program, the behavior of analog machine according to the specification document of this equipment when needs during for an equipment development simulator.For example, if a disk has certain attribute, then set up corresponding virtual device models for this simulator program.

Yet because the quantity of different types of equipment is very big, it is with high costs and consuming time making up simulator individually in these equipment each.And in the prior art, do not exist for the method for a public simulator of a plurality of equipment developments.In addition, in order to make simulator identical with real service provider as far as possible, when this simulator of exploitation, should at first read specification (the AD HOC definition that device is provided especially wherein of real service provider, otherwise this simulator is nonsensical and initialization procedure).Yet this needs very big workload.

Obviously, need a kind of method that can make up the simulator of SMI-S equipment quicker, efficient, automatically and easily in this area.

Summary of the invention

For overcoming the above-mentioned shortcoming that exists in the prior art, and the present invention has been proposed.

According to an aspect of the present invention, a kind of method and device that is used to make up the simulator of SMI-S equipment is provided, this method may further comprise the steps: realize the service of core profile according to SMI-S for relevant common apparatus type, thereby the kernel service that is formed for described common apparatus type provides device, and wherein said core profile service comprises the core CIM class that is used for described common apparatus type; From the real service provider of the SMI-S equipment that will simulated, excavate the mode-definition and the instance data of specific CIM class, and in local storage vault, make up the described specific CIM class and the example; And will be mapped to the core CIM class that described core profile service comprises from the specific CIM class in the described real service provider, make described core profile service can use the described specific CIM class and the example in the described local storage vault to operate, thereby form the simulator of described SMI-S equipment.

Advantage of the present invention comprises:

It provide a kind of automatically, the method that is easy to makes up the simulator that is used for real hardware device (and service provider), this is very important for development﹠ testing based on the device management software of CIM;

I. the device that is used to make up the simulator of SMI-S equipment of the present invention

The device that is used to make up the simulator of SMI-S equipment of the present invention is described with reference to the accompanying drawings.

Fig. 3 shows the device of the simulator that is used to make up SMI-S equipment according to an embodiment of the invention.As shown in the figure, this device 300 that is used to make up the simulator of SMI-S equipment comprises core services module 301, excavates module 302, mapping block 303, and preferably also comprise device management module 304, virtual unit storage vault 305, and CIMOM 306.Respectively each module of the device 300 of the simulator that is used for making up SMI-S equipment according to an embodiment of the invention is elaborated below.

A. core services module

Core services module 301 is used for realizing the service of core profile according to SMI-S for relevant common apparatus type, thereby the kernel service that is formed for described common apparatus type provides device, wherein said core profile service comprises the core CIM class that is used for described common apparatus, promptly is the CIM class of the standard of this common apparatus defined among the SMI-S.In a preferred embodiment of the invention, described core services module is used to following four types common apparatus type to realize the service of core profile: disk array, tape pool, switch and HBA.

In other words, will realize the service of core profile according to the SMI-S process of standard, promptly the standard feature of related hardware equipment for example, is realized the implementation that volume is created.Four kinds of type of hardwares in present SMI-S, have been defined, therefore, core services module 301 according to a preferred embodiment of the invention will comprise that following four types kernel service provides device: the kernel service of disk array, tape pool, switch and HBA provides device, and every type kernel service provides device to comprise to be used for one group of kernel service of relevant device type.The core profile service of every kind of equipment is stipulated in SMI-S.

Fig. 4 shows the concrete steps that realize the service of core profile according to embodiments of the invention.

As shown in the figure,, read the profile among the SMI-S, for example the profile of disk array, tape pool, switch and HBA etc. in step 401.

In step 402, select the profile service of required simulation in each profile.

In step 403, realize the function in these profile services, i.e. the order of (establishment/deletion/modification) related class example is handled in definition.In a preferred embodiment of the invention, realize function in the profile service by programming in the manner known to persons skilled in the art.

In step 404, with the data storage of class example in local storage vault.

Wherein,

step

403 and 404 can be overlapped.In other words, in the function course in realizing the profile service, may create and in storage vault the storage class example, and may delete or revise the class example that is stored in the storage vault.

Only as example, the disk array kernel service in the core services module 301 provides the kernel service of device to comprise according to an embodiment of the invention:

■CIM_StoreageConfigurationService

■CIM_SoftwareInstallationService

■CIM_StorageHardwareManagementService

■CIM_ControllerConfigurationService

■CIM_StoragePool

■...

Therefore, in core services module 301 of the present invention, will support the method (being function) in these services, for example, the CreateOrModifyStoragePool method among the CIM_StorageConfigurationService.

Fig. 5 shows the model that is used for this CreateOrModifyStoragePool method among the SMI-S.According to this model, realize that the step of this CreateOrModifyStoragePool method (promptly handling relevant CIM class example) can be as follows:

1. create the CIM_StoragePool example;

2. inquire about parent CIM_ComputerSystem example;

3. create association class example: CIM_AllocatedFromStoragePool;

4. create association class example: CIM_HostedStoragePool;

5. the attribute of the CIM_StoragePool example of being created is set;

6. create the ConcreteJob example;

7. create CIM_AffectedJobElement.

Similarly, for the additive method among the described CIM_StorageConfigurationService, described disk array kernel service provides the additive method of other services in the device, and each method of each service in other device core service providers, also can realize, thereby be formed for the device core service provider of each common apparatus type according to the model about this method among the SMI-S.

Be to be noted that the above only is example, rather than limitation of the present invention.For example, in other embodiments of the invention, described core services module 301 can be used for for more than, be less than or be different from described four types device type and realize the service of core profile.As long as there is specification about the standard profile service of certain device type, just can use said method, according in this specification about the related description of each method in the service of the standard profile of this device type, realization is used for the various functions of the various services of this device type, and and then realizes the service provider of this device type.

B. excavate module

Excavation module 302 is used for excavating from the real service provider of the SMI-S equipment that will simulated the mode-definition and the instance data of specific CIM class, and in local virtual equipment storage vault, make up described specific CIM class and the example (in this article, described specific CIM class should be understood to include all classes in the real service provider, the expansion class that had both comprised this service provider that the SMI-S standard class is expanded and obtained, also comprise service provider the SMI-S standard class that directly adopts).Preferably, described excavation module 302 uses the depth-first class mining algorithm of the correct order that can obtain class to carry out described excavation, and carries out described structure according to the correct order of the class of described acquisition.

For example, when desire is that the service provider of the hardware device of a certain type in described four types is when generating simulator, to excavate the real service provider that module 302 is connected to this hardware device, and use depth-first class mining algorithm to excavate the storage vault of this real service provider.Mining process has two targets: excavate quasi-mode definition all in the real service provider, and it is building up in the storage vault; And excavate all examples under each class, and it is copied in the local storage vault.Therefore, after excavation, will there be the duplicate complete storage vault of storage vault in this locality with real service provider.By excavating, obtained the mode-definition of all the CIM classes in the real service provider, and obtained the instance data in the real service provider.

When making up class and copying to instance data in the local simulator storage vault, need to solve following several problems:

At first, some class among the CIM is used as superclass, or is used as the data type of another kind of attribute, method rreturn value or method parameter.For example:

class?CIM_StorageConfigurationService：CIM_Service{

uint32?CreateOrModifyStoragePool(

string?ElementName，

CIM_ConcreteJob?REF?Job，

CIM_StorageSetting?REF?Goal，

unit64?Size，

string?InPools[]，

string?InExtents[]，

CIM_StoragePool?REF?Pool)；

……

}

Therefore, when CIM_StorageConfigurationService being building up in the local storage vault, CIM_Service should exist, and in other words, should make up CIM_Service before making up CIM_StorageConfiguration.

Secondly, also have some association classes in CIM, these association classes are used for the example of two classes is associated, and object path (being taken as the key word of example) will be placed in the example of association class.Therefore, this requires the example of these two classes to be replicated before should being replicated at the example of association class.

For addressing these problems, used following scheme in the present invention: at first, in mining process of the present invention, obtain the correct order of class; Secondly, after excavating, use the correct class order that is obtained that class is building up in the local storage vault; At last, also use this correct class order that the example of class is copied in the local storage vault.

According to a preferred embodiment of the invention, in mining process, use depth-first class mining algorithm to excavate class and obtain its correct order.Fig. 6 shows the exemplary realization of this depth-first class mining algorithm.

As shown in the figure, in step 601, excavate the service provider (the existing C IMOM that passes through) that module 302 is connected to real hardware device.

In step 602, excavate module 302 and from real service provider, obtain any one class, and such is pushed storehouse.

Whether in step 603, judging has class to need to excavate in the storehouse.If the result that should judge is for denying then process end.If the result of this judgement is for being then to forward step 604 to.

In step 604, from storehouse, take out a class.

In step 605, judge whether such is excavated.If the result of this judgement is for being then to turn back to step 603.If the result that should judge then forwards step 606 to for not.

In step 606, enumerate all properties in such, and it is pushed storehouse.

Whether in step 607, judging has attribute to need to excavate in the storehouse.If the result of this judgement is for being then to change step 608 over to.If the result that should judge then forwards step 611 to for not.

In step 608, from storehouse, take out an attribute.

In step 609, judge whether the data type of this attribute is the class of not excavated.If the result that should judge then turns back to step 607 for not.If the result of this judgement is for being then to forward step 610 to.

In step 610, this class of not excavated is pushed storehouse, and then turn back to step 604, thereby this class of not excavated is carried out processing same as described above.

In step 611, enumerate all methods in the current class, and these methods are pushed storehouse.

Whether in step 612, judging has method to need to excavate in the storehouse.If the result that should judge then forwards step 621 to for not.If the result of this judgement is for being then to forward step 613 to.

In step 613, take out a method from storehouse.

In step 614, judge whether the return type of this method is the class of not excavated.If the result of this judgement is for being then to forward step 615 to.If the result that should judge then forwards step 616 to for not.

In step 615, the described class of not excavated is pushed storehouse, and then turn back to step 604, thereby this class of not excavated is carried out the processing identical with the above.

In step 616, enumerate all parameters of this method, and these parameters are pushed storehouse.

Whether in step 617, judging has parameter to need to excavate in the storehouse.If the result that should judge then turns back to step 612 for not, need the next method (if any) excavated in the storehouse so that handle.If the result of this judgement is for being then to forward step 618 to.

In step 618, from storehouse, take out a parameter.

In step 619, judge whether the data type of this parameter is the class of not excavated.If the result that should judge then turns back to step 617 for not, so that handle presumable next parameter in the storehouse.If the result of this judgement is for being then to forward step 620 to.

In step 620, this class of not excavated is pushed storehouse, and then turn back to step 604, thereby such is carried out processing same as described above.

In step 621, current class is put into sequential list.

After above process was complete, if the class of not excavated in addition in real service provider then repeats above process, classes all in real service provider were all excavated.

Through such mining process, in described sequential list, will preserve all classes of from real service provider, excavating with correct order, thereby excavate module 302 and can in local storage vault, make up all classes of from real service provider, excavating, excavate module 302 then and can from real service provider, excavate and in local storage vault, duplicate the instance data of each CIM class according to this order.Like this, the simulator that makes up according to embodiments of the invention can form a virtual unit according to the class instance data of being stored in this this locality storage vault in operational process, this virtual unit will have and real hardware device and identical characteristic and the behavior of service provider thereof.

Be to be noted that above-mentioned depth-first class mining algorithm only is an example, rather than limitation of the present invention.In other embodiments of the invention, the concrete steps of described depth-first class mining algorithm can be with above-mentioned different.For example, can current class not put into sequential list in the step 621 of this algorithm, but directly such is structured in the local storage vault.In brief, excavate module 302 and can use any other can from real service provider, excavate the class and the example that wherein comprises, and in the correct order it is building up to algorithm or the method in the local storage vault.

In addition, although in the above description, from real service provider, excavate the mode-definition and the instance data of specific CIM class, obtain the correct order of these classes, and the function that makes up the described specific CIM class and the example in local storage vault is finished by described excavation module 302, but this only is an example, rather than limitation of the present invention.In other embodiments of the invention, these functions can be finished by different modules respectively.

C. mapping block

Mapping block 303 is used for the specific CIM class from described real service provider is mapped to the core CIM class that comprises in the described core profile service, make that described core profile service can be according to the request from CIM client, use the described specific CIM class and the example in the described local storage vault to operate, thereby form the simulator of described SMI-S equipment.Wherein, described mapping comprises and will be mapped to the kernel service class of described core profile service from the specific CIM service class in the real service provider, and will be mapped to the corresponding core CIM class that comprises in the described core profile service from other the specific CIM classes in the real service provider.Preferably, described mapping step also comprises provides device to be registered among the CIMOM explicitly specific CIM service class and described kernel service.

In other words, device 300 at the simulator that is used for making up SMI-S equipment according to an embodiment of the invention, used the core CIM class that kernel service comprised in the core services module 301 to represent with operated specific CIM class, therefore after the performed mining process of above-mentioned excavation module 302, mapping block 303 is mapped to described core CIM class with the corresponding specific CIM class in the real service provider, like this, when CIM client operates SMI-S equipment by the CIMOM request, specific CIM class rather than core CIM class in the virtual unit will be operated.

In a preferred embodiment of the invention, mapping block 303 by the title of the core CIM class in mapped file, set up and specific CIM class to realizing described mapping.

This mapping is important, this be because, specific service provider will define it and inherit certain kinds standard C IM class, that have AD HOC, for example, in SMI-S, CIM_ComputerSystem is the standard class that is used for the overlay device object, but in StorageBlade, for it has defined subclass Aristos_ControllerSystem, and in DS4000, subclass is LSISSI_StorageSubsystem.Again for example, in StorageBlade, Aristos_StoragePool has inherited the standard class CIM_StoragePool among the SMI-S.In order to make simulator of the present invention have the behavior identical with the equipment that simulated, should make the specific class of simulator operation, rather than the core classes in the core services module 301.

In addition, specific service provider will define its specific service class, therefore, when when kernel service of CIMOM registration provides device, should use specific service class title, rather than kernel service provide the title of the standards service class in the device.For example, in StorageBlade, Aristos_StorageConfigurationService has inherited CIM_StorageConfigurationService, therefore when the registration kernel service provides device in CIMOM, should use Aristos_StorageConfigurationService, rather than CIM_StorageConfigurationService.Only in this way, when the user called the method for specific service, kernel service of the present invention provided device just can obtain notice, and carries out desired operation.

Fig. 7 shows the synoptic diagram of mapping mechanism of the present invention.As shown in the figure, provide the device set to have some kernel services in the kernel service that is used for a common apparatus of the present invention, some core classes are operated in each kernel service.Mapping block 303 of the present invention will be mapped as the specific service from the true CIM service provider that simulated equipment kernel service corresponding core service in the device set will be provided, and being mapped as the corresponding core classes that kernel service comprises from other certain kinds in the real service provider that simulated equipment.

In a preferred embodiment of the invention, use simple title that mapping mode is set up mapping relations, its form is as follows:

Delegate_Class_Name＝Target_Class_Name

For example " CIM_ComputerSystem=Aristos_ControllerSystem ".

Preferably, described title is to being stored in the mapped file, and like this, simulator of the present invention will read the certain kinds corresponding with needed core classes from this mapped file when operation.If do not provide mapping, then, will use this core classes (standard class among the SMI-S) itself as acquiescence for certain core classes.This mapped file both can also can be formed by automatic or automanual mode by the specification edit of user according to real service provider.

Fig. 8 shows and uses automanual mode to come to provide core classes in the device to set up the process of mapping relations as kernel service according to one embodiment of present invention.

As shown in the figure, in step 801, the acquisition kernel service provides the core classes in the device.

In step 802, search for the certain kinds in the current real service provider.Preferably, this search step is after described excavation module 302 is excavated the certain kinds in the service provider of real equipment in the local storage vault 305, carries out in described local storage vault.Certainly, also can be directly from the service provider search certain kinds wherein of real equipment.

In step 803, judge whether to exist the certain kinds of having inherited this core classes.If the result of this judgement is for being then to forward step 804 to.If the result that should judge then forwards step 805 to for not.

In step 804, judge whether the certain kinds that only exists to inherit this core classes.If the result of this judgement is for being then to forward step 807 to.If the result that should judge then forwards step 806 to for not.

In step 805, core classes is mapped to self.This step both can by in a mapped file, set up this core classes to self title to realizing, it is right to the title of self also can not set up core classes in mapped file, but when simulator moves, as acquiescence, will in mapped file, not exist corresponding title that the core classes of mapping is mapped as self.

In step 806, specify a certain kinds by the user.The user can specify a certain kinds, the certain kinds of perhaps specifying needs to operate on it arbitrarily.

In step 807, this certain kinds is mapped to core classes.Preferably, this step be by in a mapped file, set up this certain kinds to the title of this core classes to realizing.

In step 808,, then provide device to be registered among the CIMOM explicitly this specific service class and kernel service if this certain kinds is a service class.

Preferably, above process is for providing each the core classes iteration in the device to carry out with current device-dependent each kernel service that will simulate.

Be to be noted that said process only is example, rather than limitation of the present invention.In brief, anyly can set up the core classes in the core services module 301 and the method for the mapping relations between the certain kinds in the service provider of equipment of simulation all is suitable for.For example, also can in core services module 301, search corresponding core classes and shine upon at current with each certain kinds in each service provider of equipment of simulation.Again for example, said process also may fully automatically be carried out, and wherein in step 303, selects a certain kinds automatically by mapping block 303.

Fig. 9 shows the mode that mapping mechanism according to an embodiment of the invention plays a role in the operational process of simulator of the present invention.

As shown in the figure, in step 901, CIMOM receives the client requests for the specific service of certain hardware device from CIM client.

In step 902, CIMOM searches corresponding kernel service device is provided.

In step 903, CIMOM judges whether to find corresponding kernel service that device is provided.If the result that should judge is for denying then process end.If the result of this judgement is for being then to forward step 904 to.

In step 904, this kernel service that brings into operation provides device.

In step 905, provide in the operational process of device in this kernel service, judge according to the mapping relations of having set up whether the core classes that this kernel service provides device to use has corresponding certain kinds.If the result of this judgement is for being then to forward step 906 to.If the result that should judge then forwards step 907 to for not.

In step 906, handle the example of pairing certain kinds.

In step 907, handle the example of core classes.

D. device management module

Device management module 304 is used for being provided with according to the user, the instance data in the described local storage vault is configured, thereby can expands and be configured in virtual unit and the assembly thereof that is generated when simulator moves.Preferably, described device management module 304 carries out described configuration according to the configuration file of being created or being revised by the user.
