Technical Field
The invention relates to the technical field of storage, in particular to a method and a device for issuing input/output (English abbreviation: I/O).
Background
When an existing complex storage system or other block devices are downloaded from a host I/O to a device driver, many subsystem designs need to process I/O, such as I/O scheduling, I/O splitting, I/O sequencing, I/O merging, I/O flow control, and the like. Therefore, the number of read/write (I/O) operations per second (I/O) becomes a key index for measuring the performance of the storage system, and I/O path verification for verifying the relative capability of the IOPS becomes very critical.
Currently, for the I/O path verification of the whole system block, the I/O input is based on the I/O issued by the client (such as the host) or the I/O issued by the array controller on the storage server side in the storage system. However, in the prior art, when issuing I/O based on the array controller, it is common to issue I/O to the array controller side for Logical Unit Number (LUN), or to issue I/O for a specific layer, such as a cache layer. That is, the solution can only develop specific tools for a few specific subsystems, and has limited application, insufficient versatility, and high maintenance cost.

Detailed Description
For clarity and conciseness of the following description of the various embodiments, a brief introduction to the relevant concepts is first given:
as shown in fig. 1, an existing network Storage (SAE) system includes a plurality of clients and a plurality of storage servers, where each storage server includes an array controller, and the clients communicate with the storage server through a switching network.
Specifically, in the storage server, the I/O processing path is as shown in fig. 2. In FIG. 2, the I/O processing hierarchy includes:
s1, Small Computer System Interface (SCSI) target frame (TGT) receives SCSI command from host and converts it into internal I/O request.
S2, the LUN forwards the I/O to the corresponding controller according to the working controller of the LUN accessed by the I/O.
S3, volume receives I/O forwarded from LUN, and processes the logic of Thin, increment, etc. to map the address space to block.
S4, the volume cache caches dirty data from the volume and provides read data prefetch hits and mirroring functions. The dirty data is specifically modified data.
S5, the extension maps the address space to a combination (CHUNK group, CKG) formed by multiple chunks from different hard disks in the same Disk Group (DG) according to certain Redundant Array of Independent Disks (RAID) attributes. The chunk refers to a physical space of a fixed size into which a hard disk space in the storage pool is divided.
S6, CKG forwards I/O to corresponding controller according to the control right of the extension, processes local I/O, provides RAID function for the local I/O, and maps the address space to the logic hard disk.
S7, stripe cache caches dirty data from CKG, and provides metadata cache, mirror and write hole (writehole) protection functions.
S8, Block Device Management (BDM) maps the I/O space of the logic hard disk to the I/O space of the physical hard disk, and provides functions of I/O sequencing, multipath and the like.
S9, the INI driver (driver, DRV) sends the I/O to the hard disk.
As described in the background art, in the prior art, when issuing I/O based on an array controller, the I/O is usually issued to a LUN in a side direction of the array controller, or issued to a specific layer, such as a cache layer. That is, the solution can only develop specific tools for a few specific subsystems, and has limited application, insufficient versatility, and high maintenance cost.
Based on this problem, embodiments of the present invention provide a method and an apparatus for issuing an I/O, so as to at least solve the above problem. The core idea is as follows: as can be seen from the above whole I/O processing flow, the subsystem inputs such as LUN, volume, cache, CKG, BDM and the like all have some common information, such as I/O operation type, starting sector, sector number and the like. Considering these common features, a general method for issuing I/O is implemented, and I/O input can be provided to each subsystem on the array controller side based on the features of the operation type (read operation or write operation) of the access I/O, the object identification, the starting sector, the number of sectors, the size of single I/O or sequential I/O or random I/O, I/O, the I/O load, and the like.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As used in this application, the terms "component," "module," "system," and the like are intended to refer to a computer-related entity, either hardware, firmware, a combination of hardware and software, or software in execution. For example, a component may be, but is not limited to being: a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of example, both an application running on a computing device and the computing device can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures thereon. The components may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the internet with other systems by way of the signal).
This application is intended to present various aspects, embodiments or features around a system that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.
Additionally, in the embodiments of the present invention, words such as "exemplary," "for example," and the like are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary," "e.g.," is not to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the words "exemplary," "e.g.," is intended to present concepts in a concrete fashion.
The scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.
As shown in fig. 3, a schematic flow chart of a method for issuing an I/O according to an embodiment of the present invention includes steps S301 to S303:
s301, the device for issuing the I/O obtains and analyzes the I/O mode setting information of the first service subsystem.
S302, the device for issuing the I/O instantiates the I/O input interface of the first service subsystem which is registered in advance according to the I/O mode setting information of the first service subsystem, and obtains an I/O stream corresponding to the I/O input interface of the first service subsystem.
S303, the device for issuing the I/O stream sends the I/O stream to the first service subsystem.
Specifically, in step S301 in the embodiment of the present invention:
the first service subsystem may specifically be TGT, LUN, volume, cache, extend, CKG, BDM, or INI DRV in fig. 2, which is not specifically limited in this embodiment of the present invention.
The I/O mode setting information may specifically include I/O mode information and I/O operation information.
The I/O mode information may specifically include a starting sector, a number of sectors, a total bandwidth of single I/O or sequential I/O or random I/O, I/O, a start time or an end time, and the like, which is not specifically limited in this embodiment of the present invention.
The I/O operation information may specifically include start or stop, and the like.
It should be noted that the reason why the I/O operation information is carried is as follows: the I/O operation of each layered subsystem is independent, and the I/O operation information can be carried for conveniently and independently controlling each layered subsystem.
Optionally, in this embodiment of the present invention, the I/O mode setting information of the first service subsystem may be information obtained after the first service subsystem sets the I/O mode in a configuration file manner.
For example, the configuration file may be extensible markup language (English language) or other configuration template.
Or, the I/O mode setting information of the first service subsystem may be information obtained after the first service subsystem sets the I/O mode in a command line manner.
For example, the command line may be a diagnostic (English name: diagnose).
It should be noted that, for any of the two manners, it is first necessary to standardize the I/O mode setting arrangement output, so as to facilitate presentation of configuration files or command lines.
It should be noted that the above is only an exemplary way to enumerate two types of obtaining manners of the I/O mode setting information of the first service subsystem. Of course, the I/O mode setting information of the first service subsystem may also be obtained in other manners, which is not specifically limited in this embodiment of the present invention.
Specifically, in step S302 in the embodiment of the present invention:
the I/O instantiation method comprises the steps of performing I/O instantiation on a pre-registered I/O input interface of a first service subsystem according to I/O mode setting information of the first service subsystem, and actually performing instantiation output on input mode I/O through a certain algorithm according to the I/O mode setting information of the first service subsystem to generate a required I/O stream.
For example, if the I/O mode information is sequential I/O, the input mode I/O may be instantiated and output according to an incremental algorithm in the I/O address offset algorithm to generate the required I/O flow.
Specifically, in step S303 in the embodiment of the present invention:
after obtaining the I/O stream corresponding to the I/O input interface, the I/O stream may be sent to the first service subsystem corresponding to the I/O input interface.
For example, as shown in fig. 4, assuming that the first service subsystem is a LUN, the I/O stream may be issued to the LUN to provide I/O input for the LUN; assuming that the first service subsystem is the volume, the I/O stream can be sent to the volume to provide I/O input for the volume; assuming that the first service subsystem is the volume cache, the I/O stream may be sent to the volume cache to provide I/O input for the volume cache.
It can be seen that, in the embodiment of the present invention, the device issuing the I/O may provide I/O input for a single subsystem, or may provide I/O input for multiple subsystems simultaneously, which is not specifically limited in this embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, because the device issuing the I/O only generates a relatively pure I/O flow, the subsystem is required to be maintained for the context on which the subsystem I/O depends and the I/O flow converted into the I/O structure actually used by the subsystem, which is not limited in the embodiment of the present invention.
Optionally, as shown in fig. 5, in the embodiment of the present invention, before the apparatus issuing an I/O acquires and parses the I/O mode setting information of the first service subsystem (step S301), step S304 may further be included:
s304, the device issuing the I/O registers the I/O input interface for the first service subsystem.
That is, in the embodiment of the present invention, the first service subsystem may request the I/O interface registration request from the I/O issuing device, and then the I/O issuing device registers the I/O interface with the first service subsystem.
Of course, the I/O input interface may be respectively registered by the I/O issuing device for each level of service subsystem, where each level of service subsystem includes the first service subsystem, and this is not particularly limited in this embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, a device issuing an I/O may specifically be an array controller, may also be a device integrated in the array controller, and may also be a device independent from the array controller, which is not specifically limited in this embodiment of the present invention.
Based on the method for issuing the I/O provided by the embodiment of the invention, in the embodiment of the invention, a device for issuing the I/O acquires and analyzes the I/O mode setting information of the first service subsystem; and performing I/O instantiation on the I/O input interface of the first service subsystem which is registered in advance according to the I/O mode setting information of the first service subsystem, obtaining an I/O stream corresponding to the I/O input interface of the first service subsystem, and then sending the I/O stream to the first service subsystem. The first service subsystem can be any subsystem, so the method for issuing the I/O is a universal method for issuing the I/O, solves the problems that when the I/O is issued on the side of the conventional array controller, only specific tools can be developed for a few specific subsystems, the application is limited, the application is not universal enough, and the maintenance cost is high, can provide I/O input for any single subsystem, and can also provide I/O input for a plurality of subsystems simultaneously. Furthermore, because the I/O input of each stage of subsystem is independent, the upper stage subsystem is not required to be relied on, and the convergence of subsystem verification is accelerated.
