Technical Field

[0001] This disclosure relates to a virtualization apparatus, and more specifically, to a virtualization apparatus including a storage device and a computing device, and a method of operating the same. Background Technology

[0002] Storage virtualization technology provides virtual machines with the resources of actual storage devices. A virtual machine can be a software-implemented computing environment on which an operating system or applications can be installed and run. A virtual machine can read data stored in the actual storage device based on read requests, or store data in the actual storage device based on write requests.

[0003] To effectively manage large volumes of data and improve security, storage devices can store data compressed or encrypted by the host device's processor or a separate computing device, rather than storing data received from virtual machines as is. If the computing technology used for virtual machines is implemented in software, the resource burden on the host device may increase, and data processing speed may decrease. A method may be required to reduce the resource burden on the host device, ensure high-speed data communication between devices, and simultaneously provide computing and storage resources for virtual machines.

[0024] The embodiments of this disclosure will now be clearly and thoroughly described so that those skilled in the art can readily implement them.

[0025] The constituent elements described with reference to terms such as unit, module, and layer used in the detailed description, and the functional blocks shown in the accompanying drawings, can be implemented in software or hardware, or a combination thereof. For example, software can be machine code, firmware, embedded code, and application software. Hardware can include electrical circuits, circuits, processors, computers, integrated circuits, integrated circuit cores, pressure sensors, inertial sensors, microelectromechanical systems (MEMS), passive components, or combinations thereof.

[0026] Figure 1 This is a block diagram of a storage system according to an embodiment of the present disclosure. (Refer to...) Figure 1 The storage system 100 may include a host device 110, a computational storage virtualization (CSV) device 120, a storage device 130, a computing device 140, an input / output (I / O) memory management unit 150, and a high-speed serial computer expansion bus standard (PCIe) circuit 160.

[0027] Storage system 100 can provide virtual machines (VMs). A VM can be a software-implemented computing environment on which an operating system or applications can be installed and run. In some embodiments, storage system 100 can be a server device. For example, storage system 100 can be a server device that provides users with a cloud computing environment including virtual machines (VMs).

[0028] The host device 110 may include a processor and host memory. The processor of the host device 110 can run a virtual machine (VM) by executing instructions stored in the host memory. For example, the processor of the host device 110 can actually perform calculations for the operating system (OS) and applications running on the virtual machine (VM).

[0029] The processor of host device 110 can manage requests for data processing for virtual machines (VMs) (e.g., read requests, write requests, etc.). Host memory can manage data to be provided to storage device 130 based on write requests from virtual machines (VMs) and data to be received based on read requests from storage device 130.

[0030] The CSV device 120 can provide a virtualization environment based on a virtual machine (VM) to the storage device 130 and the computing device 140. The CSV device 120 can provide storage and computing resources to the virtual machine (VM) without the resource management burden of the host device 110.

[0031] For example, the CSV device 120 can communicate with the host device 110 running a virtual machine (VM). The CSV device 120 can also communicate with the storage device 130 and the computing device 140. The CSV device 120 can transform the VM's requests into requests that can be executed by the storage device 130 and the computing device 140. The storage device 130 and the computing device 140 can then process the VM's requests with the assistance of the CSV device 120, without the resource management burden of the host device 110.

[0032] In some embodiments, the CSV device 120 can ensure direct communication between different devices. For example, the CSV device 120 can facilitate direct data communication between the host device 110 and the storage device 130, between the host device 110 and the computing device 140, and between the storage device 130 and the computing device 140 via the PCIe circuit 160. Direct data communication can also be referred to as Direct Memory Access (DMA) communication.

[0033] In some embodiments, the CSV device 120 may be implemented as a hardware accelerator. For example, the CSV device 120 may be implemented as a Field Programmable Gate Array (FPGA). The FPGA may be hardware that manages storage and computing resources for a virtual machine (VM).

[0034] In some embodiments, the CSV device 120 can flexibly manage storage and computing resources. For example, to enable the hostless device 110 to handle requests from multiple virtual machines (VMs) resource-intensively, the CSV device 120 can allocate resources to multiple storage devices and multiple computing devices. This will be discussed later in conjunction with... Figure 10 Let's explain this in detail together.

[0035] Storage device 130 can store data. For example, storage device 130 can provide data based on read requests from a virtual machine (VM), or it can store data based on write requests from a virtual machine (VM). Storage device 130 can store data processed by computing device 140.

[0036] The computing device 140 can process data provided by the storage device 130 or the host device 110. For example, in the event of a read request issued by a virtual machine (VM), the storage device 130 can provide the raw data stored therein to the computing device 140 under the management of the CSV device 120. The computing device 140 can process the raw data and provide the processed data to the host device 110.

[0037] As another example, when a write request is issued by a virtual machine (VM), the computing device 140 can receive raw data from the host device 110 according to the management of the CSV device, the computing device 140 can process the raw data, and the storage device 130 can store the data processed by the computing device 140.

[0038] In some embodiments, computing device 140 may perform data compression or encryption. For example, in the event of a read request issued by a virtual machine (VM), computing device 140 may receive the original data corresponding to the read request from storage device 130, decompress or decrypt the original data, and provide the decompressed or decrypted data to host device 110.

[0039] As another example, when a write request is issued by a virtual machine (VM), the computing device 140 can receive the raw data corresponding to the write request from the host device 110, compress or encrypt the raw data, and provide the compressed or encrypted data to the storage device 130.

[0040] In some embodiments, computing device 140 may be implemented as a hardware accelerator. For example, computing device 140 may be implemented as an FPGA. An FPGA may be hardware that provides computing resources.

[0041] The I / O memory management unit 150 can manage the mapping relationship between the virtual addresses of a virtual machine (VM) and the physical addresses corresponding to the VM's physical machine (i.e., host device 110). For example, the VM can be implemented as software running by the processor of the host device 110, and the virtual address of the data managed by the VM can correspond to the physical address of the data stored in the host memory of the host device 110. The I / O memory management unit 150 can translate virtual addresses into corresponding physical addresses, and vice versa.

[0042] In some embodiments, where the CSV device 120 includes an address translation table that manages the mapping between virtual addresses and physical addresses, the I / O memory management unit 150 may be omitted. Alternatively, the address management table and the I / O memory management unit 150 within the CSV device 120 may be used together for managing virtual addresses and physical addresses.

[0043] PCIe circuit 160 can be connected to host device 110, CSV device 120, storage device 130, computing device 140, and I / O memory management unit 150. PCIe circuit 160 can provide a direct interface environment for any combination of CSV device 120, storage device 130, computing device 140, and I / O memory management unit 150. For example, storage device 130 can communicate directly with computing device 140 via PCIe circuit 160.

[0044] As described above, according to this disclosure, the CSV device 120 provides a virtualization environment to the storage device 130 and the computing device 140. Since the CSV device 120 is implemented as a separate hardware component rather than a software module, the resource management burden on the host device 110 can be reduced. The CSV device 120 can ensure direct communication with any combination of the host device 110, storage device 130, and computing device 140 by translating requests from virtual machines (VMs).

[0045] Figure 2 This is described based on a portion of the embodiments disclosed herein. Figure 1 A block diagram of the storage system. (Refer to...) Figure 1 and Figure 2 The storage system 100 can be divided into a host side and a storage side. The storage side can also be called a virtualization device (VD).

[0046] The host side may include host device 110 and a virtual machine (VM) running on host device 110. The host device may include a CSV drive. The CSV drive may be software that stores information necessary for communication with CSV device 120. Host device 110 can communicate with CSV device 120 by running the CSV drive.

[0047] The storage side may include a CSV device 120, a storage device 130, a computing device 140, and an I / O memory management unit 150.

[0048] The CSV device 120 can communicate directly with the host device 110 or through the I / O memory management unit 150. The CSV device 120 may include a single root input / output virtualization (SR-IOV) adapter 121 and a device orchestrator 122.

[0049] The SR-IOV adapter 121 can provide an interface with a virtual machine (VM). The SR-IOV adapter 121 enables the VM to access the storage device 130 or the computing device 140 without going through a separate software layer.

[0050] The device orchestrator 122 can identify the virtual machine (VM) via the SR-IOV adapter 121. The device orchestrator 122 can identify the storage device 130 and the computing device 140. The device orchestrator 122 can allocate storage resources for the storage device 130 and computing resources for the computing device 140 of the virtual machine (VM).

[0051] Device orchestrator 122 can generate redirection requests to be provided to storage device 130 and processing requests to be provided to computing device 140 based on read requests provided by the virtual machine (VM). For example, a redirection request can be implemented by changing the destination address of the read request provided by the VM to computing device 140 instead of storage device 130. Device orchestrator 122 can generate processing requests to be provided to computing device 140 and storage requests to be provided to storage device 130 based on write requests provided by the virtual machine (VM).

[0052] Storage device 130 can communicate with CSV device 120 and computing device 140. In response to a request from CSV device 120, storage device 130 can provide data directly to computing device 140 via PCIe circuit 160, or receive processed data directly from computing device 140.

[0053] The computing device 140 can communicate with the CSV device 120 and the storage device 130. In response to a request from the CSV device 120, the computing device 140 can provide processed data directly to the storage device 130 via the PCIe circuit 160, or receive data directly from the storage device 130.

[0054] Figure 3 This is described based on a portion of the embodiments disclosed herein. Figure 1A block diagram of the storage system. (Refer to...) Figure 1 and Figure 3 The storage system 100 may include a host device 110, a CSV device 120, a storage device 130, a computing device 140, an I / O memory management unit 150, and a PCIe circuit 160.

[0055] Storage system 100 can identify a virtual machine (VM) as a target virtual machine among multiple virtual machines. Storage system 100 can identify storage device 130 as a target storage device among multiple storage devices. Storage system 100 can identify computing device 140 as a target computing device among multiple computing devices.

[0056] To handle requests from multiple virtual machines, storage system 100 can flexibly allocate storage resources from multiple storage devices and computing resources from multiple computing devices. When the number of virtual machines, storage devices, and computing devices increases or decreases, storage system 100 can reallocate storage and computing resources for the changed virtual environment.

[0057] Host device 110 may run a virtual machine (VM). The VM may include a Virtual Submission Queue (VSQ) and a Virtual Completion Queue (VCQ). A VSQ may be a memory to be written to by a command requested by the VM. A VCQ may be a memory that receives completion acknowledgments indicating the completion of a command written to a corresponding VSQ. VSQs and VCQs may have a corresponding relationship. The virtual addresses of VSQs and VCQs may correspond to a portion of the host memory of host device 110.

[0058] Host device 110 may include host memory. Storage device 130 may include buffer memory. Computing device 140 may include buffer memory. Any combination of the host memory of host device 110, the buffer memory of storage device 130, and the buffer memory of computing device 140 can communicate directly via PCIe circuit 160.

[0059] The I / O memory management unit 150 can communicate with the host device 110 and the CSV device 120. The I / O memory management unit 150 can translate a virtual address provided by the host device 110 into a physical address and provide the physical address to the CSV device 120. The I / O memory management unit 150 can also translate a physical address provided by the CSV device 120 into a virtual address and provide the virtual address to the host device 110. In some embodiments, if the CSV device 120 includes an address translation table that manages the mapping between virtual and physical addresses, the I / O memory management unit 150 may be omitted.

[0060] The CSV device 120 may include an SR-IOV adapter 121 and a device orchestrator 122.

[0061] The SR-IOV adapter 121 can communicate with the host device 110 and the device orchestrator 122. The SR-IOV adapter 121 can include multiple Virtual Functions (VFs). Each of the multiple VFs can correspond to multiple Virtual Machines (VMs). Each of the multiple VFs can provide an interface with its corresponding Virtual Machine. The VFs enable the corresponding Virtual Machines to access the storage device 130 and computing device 140 through the device orchestrator 122 without going through a software layer. Within the SR-IOV adapter 121, each of the multiple VFs can operate as an independent device. The VFs can support the allocation of storage and computing resources to their corresponding Virtual Machines.

[0062] The device orchestrator 122 can communicate with the SR-IOV adapter 121, the storage device 130, the computing device 140, and the I / O memory management unit 150. The device orchestrator 122 may include storage interface circuitry, computing device interface circuitry, and a resource manager.

[0063] The storage interface circuitry provides an interface between the resource manager and storage device 130. The storage interface circuitry may include a Submission Queue (SQ) and a Completion Queue (CQ). An SQ may correspond to a command written to a VSQ and may be the memory to which the command to be written to storage device 130 will be stored. A CQ may be a memory that receives a completion acknowledgment indicating that the command written to the corresponding SQ has been processed. SQs and CQs may have a corresponding relationship.

[0064] The computing device interface circuitry can provide an interface between the resource manager and the computing device 140.

[0065] The resource manager can receive requests from the virtual machine (VM) via the SR-IOV adapter 121. The resource manager can communicate with the storage device 130 via the storage interface. The resource manager can communicate with the computing device 140 via the computing device interface circuitry.

[0066] The resource manager can modify a portion of the fields in a request from a virtual machine (VM) and provide it to storage device 130 or computing device 140. In the following text, it will be compared with... Figure 4 and Figure 5 Let's take a closer look at the changed fields.

[0067] The resource manager can manage multiple virtual machines (VMs), multiple storage devices, and multiple compute devices. For example, the resource manager can refer to the indexes of multiple storage devices to identify a target storage device. Similarly, the resource manager can refer to the indexes of multiple compute devices to identify a target compute device. The resource manager can then allocate the storage resources of the identified storage devices and the compute resources of the identified compute devices to the VMs.

[0068] The resource manager can manage the mapping between virtual machines (VMs) and storage devices 130. For example, the VSQ and VCQ of the VM can correspond to the SQ and CQ of the storage interface circuit, respectively. The layer of the command to write to the VSQ can be different from the layer of the command to write to the SQ. The layer of the completion confirmation to write to the CQ can be different from the layer of the completion confirmation to write to the VCQ. The resource manager can obtain the command to write to the VSQ, change the layer of the obtained command, and write the command with the changed layer to the SQ. The resource manager can obtain the complex function to write to the CQ, change the layer of the obtained complex function, and write the complex function with the changed layer to the VCQ.

[0069] In some embodiments, the resource manager may conform to the Non-Volatile Memory Express (NVMe) standard. For example, the resource manager may receive a notification from host device 110 that a command has been written to the VSQ. The resource manager can retrieve the command written to the VSQ. Based on the retrieved command, the resource manager can write a layer-modified command to the SQ. The resource manager may provide the doorbell to storage device 130. Storage device 130 can retrieve the layer-modified command from the SQ. Storage device 130 can communicate with computing device 140 to process the command.

[0070] After processing the command, storage device 130 can write a completion confirmation to the CQ. Storage device 130 can provide an interrupt notification to the resource manager. The resource manager can obtain the completion confirmation written to the CQ and write a completion confirmation indicating that the layer has been changed to the VCQ based on the obtained completion confirmation. The resource manager can provide a doorbell to storage device 130. The resource manager can provide an interrupt notification to host device 110. Host device 110 can process the completion confirmation written to the VCQ. Host device 110 can provide a doorbell to the resource manager.

[0071] In some embodiments, the resource manager may include an address translation table. The address translation table manages the mapping between virtual addresses and physical addresses. The resource manager can refer to the address translation table to translate virtual addresses into physical addresses, or vice versa. In this case, the I / O memory management unit 150 may be omitted, or the address translation table and the I / O memory management unit 150 may be used together.

[0072] In some embodiments, the resource manager may include an inner-computational device. The inner-computational device may process data received from storage device 130 or data received from host device 110. The inner-computational device may perform functions similar to computing device 140. In this case, computing device 140 may be omitted, or the inner-computational device and computing device 140 may be used together. (The following will refer to...) Figure 11 and Figure 12 Together, we will provide a more detailed explanation of the internal computing device.

[0073] Figure 4 This is a diagram illustrating a command format according to a portion of an embodiment of this disclosure. (Refer to...) Figure 1 and Figure 4 This describes the command format of the commands received from the host device 110.

[0074] In some embodiments, the command format may conform to the NVMe standard. For example, the command format may include “Op”, “Flags”, “CID”, “Namespace Identifier”, “Reserved Field”, “Metadata”, “PRP1”, “PRP2”, “SLBA”, “length”, “Control”, “Dsmgmt”, “Appmask”, and “Apptag”.

[0075] "Op" can indicate an opcode or operation code. For example, "Op" can indicate whether the operation to be processed by the command is a read operation or a write operation, etc.

[0076] "Flags" can manage the flag values ​​of persistent memory regions.

[0077] "CID" can indicate a command identifier. A command identifier can be used to distinguish one command from another.

[0078] A "namespace identifier" can be used to distinguish one namespace from another. A namespace can be a space that assigns names to files in the file system.

[0079] "Reserved fields" can indicate areas that can be changed according to the design.

[0080] Metadata can indicate or describe the data to be processed according to the command, or information related to that data.

[0081] "PRP1" can refer to the first physical region page. "PRP2" can refer to the second physical region page. The first and second physical region pages can indicate the memory address used for DMA communication.

[0082] "SLBA" can indicate the start logical block address. When multiple virtual machines share a storage device, "SLBA" can provide a different offset value to each of the virtual machines, ensuring that the addresses used by the multiple virtual machines do not overlap. Each of the virtual machines can refer to the address with the added offset value.

[0083] "Length" indicates the length of the data block in bytes. "Control" can be used to control data transfer. "Dsmgmt", "Appmask", and "Apptag" can be fields managed by the operating system or file system of the virtual machine VM or host device 110.

[0084] According to a portion of the embodiments of this disclosure, the CSV device 120 can generate a request that can be processed by the storage device 130 or the computing device 140 by changing reserved fields of the command. Reserved fields may include CSV commands proposed according to embodiments of this disclosure. (Hereinafter referred to as...) Figure 5 Let's take a closer look at the reserved fields.

[0085] Figure 5 This is described based on a portion of the embodiments disclosed herein. Figure 4 A diagram of the reserved fields. (See reference...) Figure 1 , Figure 4 and Figure 5The reserved fields of the commands received from the host device 110 can indicate the location where the CSV commands are stored (e.g., the location where the fields corresponding to the CSV commands within the host device 110 are stored).

[0086] A CSV command may include at least one of the following: operator chain identifier, source address, destination address, source size, destination size, request identifier, physical device identifier, type, direct arguments, file arguments, direct argument pointer, and file argument pointer.

[0087] The operator chain identifier can indicate the type of operation to be processed by the computing device 140. For example, the operator chain identifier can indicate an encryption operation, a compression operation, or an encryption and compression operation. Alternatively, the operator chain identifier can indicate a decryption operation, a decompression operation, or a decryption and decompression operation.

[0088] The source address indicates the location of the source requesting the processed data. The destination address indicates the location of the destination receiving the processed data.

[0089] For example, in the case of a read request issued by a virtual machine (VM), the source address may indicate a buffer memory within computing device 140 after the original data in storage device 130 is redirected to computing device 140. The destination address may indicate the host memory of the host device 110 that runs the virtual machine VM in order to provide the virtual machine VM with data processed by computing device 140.

[0090] As another example, in the case of a write request issued by a virtual machine (VM), in order for computing device 140 to receive raw data from host device 110 before the computing device 140 generates processed data, the source address may indicate the host memory of the host device 110 running the virtual machine (VM). In order for computing device 140 to process the raw data before storing it in storage device 130, the destination address may indicate the buffer memory of computing device 140.

[0091] In some embodiments, the location of the buffer memory of storage device 130 can be determined by... Figure 4 SLBA management of commands. For example, in the case of a read or write request issued by a virtual machine (VM), Figure 4 The SLBA command of the host device 110 can instruct the buffer memory of the storage device 130.

[0092] Source size can indicate the size of the data to be sent based on the source address.

[0093] Destination size can indicate the size of the data to be sent based on the destination address.

[0094] A request identifier can indicate an operation that is indicated by a request. For example, a request identifier, as an operation indicated by a request, can indicate one of operations such as a read operation, a write operation, a processing operation, a redirection operation, or a storage operation. Request identifiers can manage dependencies between different requests. For example, if the request identifier of the current request is the same as the request identifier of a previous request, the storage system 100 can retain the execution of the current request until the processing of the previous request is completed.

[0095] The physical device identifier can indicate the index of storage device 130 and the index of computing device 140. For example, storage system 100 may include multiple storage devices and multiple computing devices. Storage system 100 can identify storage device 130 as a target storage device among multiple storage devices and computing device 140 as a target computing device among multiple computing devices by referring to the index recorded in the physical device identifier.

[0096] The type can indicate whether access to storage device 130 is required.

[0097] Direct parameters can indicate the location in the host memory of the host device 110 where information used in the processing operations of the computing device is stored. For example, direct parameters can indicate the location in the host memory where parameters such as functions, algorithms, hash functions, and key values ​​used in processing operations such as compression, decompression, encryption, and decryption are stored.

[0098] File parameters can indicate the location within storage device 130 where copied information used in the processing operations of the computing device is stored. For example, file parameters can indicate the location within storage device 130 where parameters such as functions, algorithms, hash functions, and key values ​​for processing operations such as compression, decompression, encryption, and decryption are copied.

[0099] A direct parameter pointer can be a field that stores a pointer to the direct parameter being sent.

[0103] In step S120, the virtualization device VD can determine whether the request in step S110 indicates a compute-store operation. For example, if the requested reserved field exists, the virtualization device VD can determine that it indicates a compute-store operation; if the requested reserved field is null, the virtualization device VD can determine that it does not indicate a compute-store operation. When it is determined that the request indicates a compute-store operation, the virtualization device VD can execute step S130. When it is determined that the request does not indicate a compute-store operation, the virtualization device VD can execute step S170.

[0104] In step S130, the virtualization device VD can obtain the address of the physical machine corresponding to the virtual machine VM and the address of the computing device 140. The physical machine corresponding to the virtual machine VM can instruct the host device 110.

[0105] In some embodiments, in step S130, the virtualization device VD can check whether there are direct parameters or file parameters in the requested reserved fields. If there are direct parameters or file parameters, the direct parameters or file parameters can be read.

[0107] In step S150, the CSV device 120 of the virtualization device VD may provide a data read redirection request to the storage device 130. At this time, the redirection request may instruct the original data stored in the storage device 130 to be provided to the computing device 140.

[0108] In step S151, the CSV device 120 of the virtualization device VD can provide a data read processing request to the computing device 140.

[0111] In step S161, the CSV device 120 of the virtualization device VD can provide a storage request for the processed write data to the storage device 130. At this time, the storage request can instruct the storage device 130 to receive the processed write data from the computing device 140 and to store the processed write data.

[0112] Returning to operation S120, if it is determined in step S120 that a request is not indicated for computational storage operations, then the virtualization device VD can execute step S170.

[0113] In step S170, the virtualization device VD can perform general storage operations. General storage operations can refer to general read operations or general write operations that are not accompanied by compression, decompression, encryption, decryption, or other processing operations of the internal computing device within the computing device 140 or CSV device 120.

The write operation can instruct the raw data RDT corresponding to the virtual address of the virtual machine VM to be written to the storage device 130. The first address ADD1 can indicate the virtual address of the virtual machine VM.

[0127] In the third operation ③, the CSV device 120 may provide the computing device 140 with a second request RQ2 indicating a third address ADD3, a fourth address ADD4, and a processing operation.

[0128] In the fourth operation ④, computing device 140 may receive raw data RDT from host device 110 based on the second request RQ2. For example, computing device 140 may perform DMA communication to host device 110 via PCIe circuit 160 based on the third address ADD3 and the fourth address ADD4 of the second request RQ2.

[0129] In the fifth operation ⑤, the computing device 140 can process the raw data RDT based on the second request RQ2 to generate the processed data PDT.

Figure 9 The storage system 100 may include a host device 110, a CSV device 120, a storage device 130, a computing device 140, and a PCIe circuit 160.

[0134] Any combination of host device 110, storage device 130, and computing device 140 can directly perform data communication (i.e., perform DMA communication) via PCIe communication. To aid in understanding this disclosure, Figure 9 This describes the operation of computing device 140 as a source providing processed data PDT to host device 110 or storage device 130, but host device 110 and storage device 130 may also operate as sources in a similar manner as described later.

[0135] The CSV device 120 can provide a source address and a destination address to the computing device 140.
