Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of virtual storage system provided by the invention and method are described further.
Fig. 1 illustrates a kind of structure of virtual storage system according to an embodiment of the invention, in the present embodiment, virtual storage system comprises Data Service Model, resources allocation/mapping block, resource structure/mapping block and load balance module, and user's request inserts the Data Service Model of the virtual storage system of layering by the calibrated bolck equipment interface.
Data Service Model is used to define the logical semantics relation between user data and the storage data, and for example snapshot semanteme, version rely on semanteme, many copies semanteme, consistance semanteme, encryption is semantic, compression is semantic and other multiple operational semanticss.Alleged user data is to the visible data of user in the present embodiment, and the storage data are the data that are stored on the physical medium.Input and output (I/O) request of upper layer application to user data that be input as of Data Service Model is output as one or more input and output sequences to the storage data, and Data Service Model is divided into data operation parts and data map parts.
The data operation parts are changed mutually the storage data on I/O requesting users data and the storage medium according to the operational semantics rule.The operational semantics rule is by keeper's function setting according to equipment when creating virtual unit.For example in encryption device, operation rule is set at the AES cryptographic algorithm, when the data operation parts receive write request, user data is calculated by the AES cryptographic algorithm, obtains storing data, sends to resources allocation/mapping block; The data operation parts are read the storage data from resources allocation/mapping block when receiving read request, decipher by the inverse operation of cryptographic algorithm and obtain user data, return to the user.Again for example, the operation rule of data compression device is set at certain compression algorithm, and the data operation parts compress the user data of write request with compression algorithm, obtains storing data; The data operation parts obtain user data with the inverse operation decompress(ion) of the storage data use compression algorithm of read request, return to the user.
The data map parts are mapped as user data requests the sequence of operation of some storage data.The rule of mapping is by keeper's function setting according to equipment when creating virtual unit.For example a kind of simple mapping ruler of Snapshot Devices relies on and copy-on-write for reading: the data map parts write down the dependence equipment of reading of each Snapshot Devices, and safeguard a bitmap (bitmap) for each Snapshot Devices and represent the update mode of data block, each represents a data block, 1 expression is upgraded, and 0 expression is not upgraded.The data map parts find the updated space of data block correspondence when receiving user's read request, if 1 just sends to resources allocation/mapping block, the 0 dependence equipment of reading that is transmitted to this equipment.The data map parts find the updated space of data block correspondence when receiving user's write request, be updated if updated space is 1 this data block of expression, then directly send to resources allocation/mapping block.If being 0 this data block of explanation, updated space was not updated, then produce one and read the request of corresponding data piece from reading dependence equipment, data with the data of reading and write request merge then, produce a new write request, putting updated space is 1, promptly produces to comprise a read request, a write request and a sequence of operation of revising updated space.
Data operation parts and data map parts can be formed Data Service Model separately, also can mutual superposition form Data Service Model, data stream to input, with the output of data operation parts input as the data map parts, to the data stream of output, with the output of data map parts input as the data operation parts.The Snapshot Devices of an encryption for example, its Data Service Model just by data operation parts and the stack of data map parts, to write request, is encrypted with the data operation parts earlier, then data encrypted is sent to the data map parts, finish the copy-on-write operation; To read request, obtain storing data by the data map parts according to data dependence relation earlier, by the data operation parts data are decrypted then, return to application program at last.
Resources allocation/mapping block, the memory resource pool of managing a plurality of different attributes, the attribute of memory resource pool comprises peak bandwidth, reliability class and unit price etc.Every kind of resource in the pond all shows as the RAID of linearity (linear) or certain type configuration.For example the peak bandwidth of linear is the bandwidth of single physical disk, does not have redundance, and reliability class is minimum, and unit price is the unit price of physical disk.The reliability of 3*RAID0 is identical with linear with unit price, and peak bandwidth then is approximately 3 times of linear.The peak bandwidth of 4*RAID5 is identical with 3*RAID0, and reliability and unit price are all than 3*RAID0 height.The peak bandwidth of 5*RAID5 is higher than 4*RAID5, and reliability and price are then between 3*RAID0 and 4*RAID5.
Resources allocation/mapping block carries out the distribution of resource between a plurality of virtual pools, safeguard the mapping table of a virtual unit address to the resource pool address, and each in the table all comprises a LBA (Logical Block Addressing) and a Resource Block address.When a write request arrives resources allocation/mapping block,, then write request is mapped as request, and sends to resource structure/mapping block Resource Block if in mapping table, find corresponding request item.If do not find corresponding item, module is according to the Resource Properties demand of application settings, selection can be satisfied the resource pool of these attribute demands, in these resource pools, select idling-resource quantity resource pool more and that price is cheap as far as possible to distribute, and the mapping relations of establishment from the logical block to the Resource Block, join in the mapping table, then write request is mapped as request, and sends to resource structure/mapping block Resource Block.When a read request arrives this module,, then read request is mapped as request, and sends to resource structure/mapping block Resource Block if in mapping table, find corresponding item.If do not find corresponding item, then return complete 0 data to Data Service Model.
The IO request of the logical space that is input as Data Service Model output of resources allocation/mapping block is output as the IO request of resource pool address space, is transmitted to resource structure/mapping block.
Resource structure/mapping block managing physical disk, and physical disk is organized into the virtual resource form with different attribute, provide storage resources to resources allocation/mapping block.Resource structure/mapping block is with the space section of being divided into of physical disk, and section is the least unit of resource structure, and the size of section is set when system creation, and for example the physical space of 1MB is set at 1 section.The attribute and the type of the storage resources that structure obtains are introduced in resources allocation/mapping block.Each resource pool is safeguarded the mapping table of a resource pool space to physical disk space.Resource structure/mapping block is provided with the monitoring function interface in each resource pool, when resources allocation/mapping block Resources allocation from resource pool was given virtual unit, this monitoring function interface will be called.If the free space that monitor-interface is found this resource pool is during less than the threshold values set, notice resource structure/mapping block carries out resource and constructs.Resource structure/mapping block is selected suitable physical disk section according to the type of this resource and the situation of physical disk, is configured to the resource of this type, joins in the resource pool.The state of physical disk comprises the size of free space and the request number that per second arrives.For example the free space of monitor-interface discovery 3*RAID5 resource pool is just notified resource structure/mapping block less than 200MB, and resource structure/mapping block is checked all physical disks, selects 3 free spaces bigger, and per second arrives the less disk of request number.On three disks, respectively get one section, use the RAID5 algorithm construction to become a RAID5 band, and these mapping relations of taking 3 disk sections to are joined in the mapping table of 3*RAID5 resource pool.
Resource structure/mapping block is receiving the I/O request that resources allocation/mapping block sends, and the mapping table according to the address search resource pool of I/O request obtains corresponding physical disk section.Linear algorithm or RAID algorithm according to this resource pool sends to the physical disk section with request then.
The load balance module is responsible in system's operational process, detects the loading condition of physical disk, writes down the arrival request number of each physical disk and physical disk section.Reach request number and volume of transmitted data obviously greater than other disk if find the per second of certain physical disk, then carry out following adjustment:
1. remapping of data migtation and resource: the load balance module is selected the free segment on the little physical disk of load, the data migtation of the frequent access section on the disk that load is big is on this free segment, revise the resource pool mapping table at this section place, make the mapping of pointing to former disk section point to new disk section;
2. the suggestion of resource structure strategy is provided to resource structure/mapping block, makes in the resource structure/mapping block construction process afterwards, preferentially select the section of the little physical disk of load.
The data I flow process of system: as shown in Figure 2, the user only need to select the logical semantics of data and the storage resources attribute that needs, and the interface that uses the virtual unit system to provide is created the deletion virtual disk when using the virtual storage system of layering; In the read-write process, carry out the explanation of logical semantics, the logical semantics of data is converted to the storage semanteme of data, and is transmitted to resources allocation/mapping block by Data Service Model; Resources allocation/mapping block carries out address translation to the mapping table of resource pool address to the request that receives according to virtual address, sends to resource structure/mapping block then; Resource structure/mapping block carries out address translation to the mapping table of physical disk address to the request that receives according to the resource pool address, according to the RAID or the linear semanteme of this resource request is sent to physical disk, finishes the I/O operation by physical disk; If read operation, the data of reading return to upper layer module successively, return to application after handling through Data Service Model.When the resource quantity in the resource pool of certain attribute reduces to a certain degree, the resource constructing module will use physical disk to construct the resource of the type, put into resource pool, to guarantee demands of applications.Simultaneously, the space of load balance module monitors physical disk and the load state of performance are by data migtation with revise the tactful mode of structure and carry out load balance between many physical disks.
The present invention separates the data logical semantics of virtual memory facilities with storage is semantic.The hierarchical virtual device systems provides several data logical semanticses such as snapshot, versions of data, data encryption, data compression and many copies.Along with the development of application technology, new data storage form can constantly produce, and the virtual storage system of layering also allows the new data logical semantics of User Defined, need not to relate to complicated data storage and resource management problem.
The hierarchical virtual device systems provides the uniform resource management semanteme, resource management is divided into resources allocation, resource structure and load balance function, improve the space utilization efficient of resource, resources idle between the virtual unit of having avoided causing because of fixed allocation, resources idle between the different attribute of avoiding causing because of the resource structure provides the load balance in the memory device.
It should be noted that at last, above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, and on using, can extend to other modification, variation, application and embodiment, think that simultaneously all such modifications, variation, application, embodiment are within the spirit and scope of the present invention.
