## Background
PRIORITY INFORMATION:
The present application is a U.S. national stage filing under 35 U.S.C. §371 of International Application No. PCT/CN2013/078576, filed on Jul. 1, 2013.
TECHNICAL FIELD
The embodiments described herein pertain generally to data migration in a storage network.
BACKGROUND
Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
Storage networks typically include data centers having data storage nodes for storing data. A data center for a web-based application, for example, may include multiple distributed data storage nodes that each has a number of storage servers. The transmission of mass data may occupy a large amount of network bandwidth and may affect the performance of other applications deployed on the same physical server. Further, when a large amount of network bandwidth is occupied, the data may be collected and analyzed by a malicious object in a same zone in an attempt to launch a side channel attack.
SUMMARY
Technologies are generally described for data migration in a storage network. The various techniques may be implemented in various systems, methods, and/or computer-readable mediums.
In one example embodiment, a method is provided that may include assigning a time requirement for a transmission of data from a first data storage node to a second data storage node, assigning a maximum channel transmission rate for each of a maximum number of available transmission channels based on predetermined parameters of a transmission channel, and transmitting the data in accordance with the time requirement and the maximum number of available transmission channels.
In another example embodiment, a computer-readable medium stores instructions that, when executed, cause one or more processors to perform operations that may comprise assigning a time requirement for a transmission of data from a first data storage node to a second data storage node, assigning a maximum channel transmission rate for each of a maximum number of available transmission channels based on predetermined parameters of a transmission channel, and transmitting the data in accordance with the time requirement and the maximum number of available transmission channels.
In yet another example embodiment, a data storage system may include a plurality of data storage nodes including a first data storage node and a second data storage node configured to respectively store data; and a processor configured to assign a time requirement for a transmission of data from the first data storage node to the second data storage node, assign a maximum channel transmission rate for each of a maximum number of available transmission channels based on predetermined parameters, and transmit the data in accordance with the time requirement and the maximum number of available transmission channels.

FIG. 2 shows an example configuration 200 of a cluster of a data center in which at least portions of data migration in a storage network may be implemented, arranged in accordance with at least some embodiments described herein. The cluster may be any one of clusters 120, 130, 140, 170, 180, and 190. As depicted, example configuration 200 may include, at least, one or more data storage nodes 202, 204, 206 and 208, each of which may include at least one processor 203, 205, 207 and 209, respectively; a local cloud network 210; and an interface 212. However, this configuration is an example only, and is not intended to be limiting in any manner, e.g., quantity of data storage nodes per cluster, or even quantity of processors per data storage node.
Each data storage node 202, 204, 206 and 208 may refer to at least one device, e.g., a server, which may be configured to receive and to store data therein.
Each data storage node 202, 204, 206 and 208 may be assigned a unique network address, e.g., an IP address, which may be an external network address or a local network address, in accordance with known network protocols. Data storage nodes 202, 204, 206, 208 corresponding to a respective cluster may be configured, designed, and/or programmed to be communicatively coupled to each other as well as to other data storage nodes corresponding to other clusters.
Each processor 203, 205, 207 and 209, corresponding to a respective data storage node, may be a microcontroller that may be configured to perform tasks, to process data, and/or to control the functionality of the respective data storage nodes 202, 204, 206 and 208. Each processor 203, 205, 207 and 209 may further be configured, designed, and/or programmed to process signals received from one or more data storage nodes corresponding to one or more other clusters and to provide instructions to migrate data based on the received signals. For example, according to one or more embodiments, each processor 203, 205, 207 and 209 may be configured assign a time requirement for the migration of data between the data storage nodes, to determine available transmission channels and to assign a maximum transmission rate of the available transmission rates based on predetermined parameters such as a length or type of the transmission channel. Further, each processor 203, 205, 207 and 209 may be configured to calculate or determine fixed transmission channels for the migration of data. The number of fixed transmission channels calculated may indicate the number of transmission channels to be utilized to perform the transmission of data. Each processor 203, 205, 207 and 209 may also be configured to select random transmission channels to be used to transmit any detected remaining data, i.e., data yet to be migrated, after initiating the migration of data using the fixed transmission channels. Thus, each processor 203, 205, 207 and 209 may be further configured, designed, and/or programmed to facilitate data migration from a respectively corresponding data storage node, e.g., data storage node 202, to another data storage node, e.g., data storage node 206, within a common cluster or to one or more data storage nodes corresponding to one or more other clusters.
In one or more embodiments, local cloud network 210 may be provided to facilitate communication between data storage nodes 202, 204, 206 and 208 within a common cluster 200. Local cloud network 210 may be similarly implemented by any one of, e.g., a wide area network (WAN) (e.g., Internet), a local area network (LAN), or any type of network suitable for performing data migration. In one or more other embodiments, network cloud 150 may facilitate communication between data storage nodes 202, 204, 206 and 208 using interface 212.
Interface 212 may refer to a network interface that may be configured, designed, and/or programmed to facilitate communication between one or more of data storage nodes 202, 204, 206, and 208 with other clusters and/or cloud providers 155 and 157, via network cloud 150. Alternatively, each data storage node 202, 204, 206 and 208 may include an associated embodiment of external network interface 212 to facilitate communication with other data storage nodes within a common cluster or one or more different clusters.
FIG. 3 shows an example configuration of a first data storage node and a second data storage node between which at least portions of data migration in a storage network may be implemented, arranged in accordance with at least some embodiments described herein. Example configuration 300 depicts a data storage node 122, i.e., a first data storage node, corresponding to cluster 120, that may include a processor 123, and a random number generator 125 and a channel controller 126; a content buffer 127 may be provided in communication with the processor 123; and a data storage node 172, i.e., a second data storage node, that may include a processor 173 and a random number generator 175. However, this configuration is an example only, and is not intended to be limiting in any manner. Data migration between data storage node 122, i.e., the first data storage, and data storage node 172, i.e., the second data storage node, will be described herein.
According to some embodiments, data storage node 122 and data storage node 172 may be hosted by a common, i.e., the same, cloud provider 155 or 157. Alternatively, data storage nodes 122 and 172 may each be hosted by a different one of cloud providers 155 and 157.
Data storage nodes 122 and 172 may each be configured to respectively store data received from other data storage nodes, which may be included in a common cluster, in a cluster in a common data center, or in another cluster corresponding to another data center. In one or more embodiments, processors 123 and 173 may be configured to independently assign a time requirement for a transmission of data from the respective data storage node 122 and 172 to the other data storage node 122 or 172. For example, processor 123 may be configured, designed, and/or programmed to assign a time requirement to transmit data from data storage node 122 to data storage node 172. Processor 123 may assign the time requirement based on, e.g., the amount of data to be transmitted. The time requirement may be assigned and stored in the respective data storage node and used when performing data transmission to monitor the timing thereof.
Further, processor 123 may be configured to determine a maximum number of available transmission channels to use in transmitting data between the data storage node 122 and data storage node 172. Processor 123 may determine the maximum number of available transmission channels based on the amount of data to be migrated from data storage node 122 to data storage node 172. Further, the maximum number of available transmission channels may be determined based on the amount of transmission channels that are not in use at the time of data migration from data storage node 122 to data storage node 172.
As described herein, “time requirement” may refer to a maximum amount of time that may be allotted to complete the data migration from data storage node 122 to data storage node 172. If data migration is not completed within the allotted time, the process may be terminated and/or the data migration process may be re-set.
Processor 123 may be further configured to assign a maximum channel transmission rate for each of the available transmission channels, upon determining the maximum number of transmission channels to be utilized to transmit data from one data storage node to another, based on predetermined parameters of each of the available transmission channels. According to one or more embodiments, the predetermined parameters may include fixed values based on the physical properties of the respective available channels or other factors that are not subject to adjustment, e.g., a length or type of the transmission channel. Data may then be transmitted from data storage node 122 to data storage node 172 at rates up to the maximum channel transmission rate for each of the respective transmission channels, in accordance with the time requirement.
Data transmission between the data storage node 122 and data storage node 172 may be facilitated based on a number of fixed transmission channels and a number of random transmission channels. Processor 123 may be configured, designed, and/or programmed to calculate a number of fixed transmission channels of the available transmission channels to facilitate the transmitting between data storage node 122 and data storage node 172. The transmission of data from data storage node 122 to data storage node 172 may be initiated through the fixed transmission channels. Processor 123 may be further configured to detect any remaining data in data storage node 122 to be transmitted to data storage node 172, after initiating of transmission of data via fixed transmission channels. Processor 123 may be configured, designed, and/or programmed to randomly select a number of random transmission channels of the available transmission channels to transmit any detected remaining data. The remaining data to be transmitted by the random transmission channels are poured into content buffer 127. The detection of any remaining data is performed by processor 124 using content buffer 127, for example. During each iteration of the random transmission, channel controller 126 of processor 124 may query whether content buffer 127 is empty. If channel controller 126 determines that content buffer 124 is empty then channel controller 126 may send a request for any remaining data from data storage node 122.
Random number generator 125 may be provided in processor 123 of data storage node 122, and configured to randomly select the number of random transmission channels on which the remaining data may be transmitted.
Random number generator 175 may be similarly provided in processor 173 of data storage node 172 and configured to randomly select the number of random transmission channels on which the remaining data may be transmitted.
Thus, FIG. 3 shows an example configuration 300 of data migration between a first data storage node and a second data storage node.
FIG. 4 shows an example configuration of fixed transmission channels and random transmission channels in accordance with some embodiments of data migration in a storage network, as described herein. As depicted in FIG. 4, fixed transmission channels 405 may include channels 1, 2, and 3; and random transmission channels 410 may include channels 4, 5, 6, 7, 8, 9 and 10. The transmission, or migration, of data described with regard to FIG. 4 is described herein with reference to features depicted and described with regard to FIG. 3, although such description is not to be interpreted as limiting of the example embodiments.
Data migration between data storage node 122 of cluster 120 and data storage node 172 of cluster 170 may be performed in accordance with the various embodiments described herein. According to some embodiments, processor 123 of data storage node 122 may calculate a number of fixed transmission channels 405, e.g., channels 1 through 3, of available transmission channels provided in the data storage system 100, to facilitate data migration between data storage node 122, i.e., the sending data storage node, and data storage node 172, i.e., the receiving data storage node. The migration of data from data storage node 122 to data storage node 172 may be initiated through fixed transmission channels 405. According to one or more embodiments, the fixed transmission channels 405 may transmit data corresponding to the applications running on data storage node, e.g., a server. When processor 123 determines that there is data remaining in data storage node 122 to be transmitted to data storage node 172, after initiating of transmission of data via fixed transmission channels 405, processor 123 may randomly select a number of random transmission channels 410 of the available transmission channels to transmit the remaining data to data storage node 172.
Processor 123 may perform the random selection of random transmission channels 410 using random number generator 125. Processor 123 may be further configured to transmit the detected remaining data using at least one of the randomly selected transmission channels 410, e.g., random transmission channel 4. According to some embodiments, processor 123 may further be configured to set up the random transmission channels 410. For example, the random transmission channels 410 may be set up by assigning a life cycle to each of the randomly selected ones of the random transmission channels 410. The life cycle of a random channel may be pre-defined as a random value. Alternatively, the life cycle of the random channel may be determined based on the amount of remaining data found in the content buffer. If no remaining data is found in the content buffer, then the life cycle of the random channel may be terminated and the random channel closed. Further, random transmission channel 4 may have a life cycle of one time interval t, while random transmission channel 5 may have a life cycle of two time intervals 2t. The life cycle of each random transmission channel 410 may range between about 20% to about 80% of a corresponding channel capacity of respective random transmission channel 410. Processor 123 may be configured to release, i.e., discontinue use thereof, the at least one random transmission channel 410, e.g., random transmission channel 4, after expiration of the life cycle thereof or after completion of transmission of the remaining data.
Processor 123 may be further configured to select another random transmission channel 410, e.g., one of the random transmission channels 5 through 10, to complete transmission of the detected remaining data upon expiration of the life cycle of the at least one random transmission channel 4. The establishment and release of the transmission channels may be performed via processor 123 or 173 of either data storage node 122 or 172. That is, according to one or more embodiments, either the sending data storage node or receiving data storage node may setup or release random transmission channels 410.
Thus, FIG. 4 shows an example configuration 400 of fixed transmission channels 405 and random transmission channels 410 in which data migration may be implemented.
FIG. 5 shows an example configuration of a processing flow of operations for data migration in a data storage network, in accordance with at least some embodiments described herein. As depicted, processing flow 500 may include sub-processes executed by various components that may be part of a data storage node of one or more of clusters 120, 130, 140, 170, 180 or 190, e.g., data storage node 122 of cluster 120 or data storage node 172 of cluster 170 as depicted and described with regard to FIG. 3. However, processing flow 500 is not limited to such components, as modifications may be made by re-ordering two or more of the sub-processes described here, eliminating at least one of the sub-processes, adding further sub-processes, substituting components, or even having various components assuming sub-processing roles accorded to other components in the following description. Processing flow 500 may include various operations, functions, or actions as illustrated by one or more of blocks 502, 504, 506, 508, 510 and/or 512. Processing flow 500 may begin at block 502.
Block 502 (Assign Time Requirement) may refer to a processor of a data storage node, e.g., processor 123 of data storage node 122, assigning a time requirement for transmission of data from respective data storage node 122 to another data storage node, e.g., data storage node 172. The time requirement to be assigned may be a maximum amount of time allotted to complete the migration of data from data storage node 122 to data storage node 172, based on the amount of data to be migrated. The time requirement may be assigned and stored in data storage node 122 for use in monitoring the timing of the transmission of data between the data storage nodes. Processing flow 500 may proceed from block 502 to block 504.
Block 504 (Determine Maximum Available Channels) may refer to processor 123 determining a maximum number of available channels for completing the data migration between the data storage node 122 and the data storage node 172. According to one or more embodiments, the determination may be made based on the amount of data to be migrated or based on the number of transmission channels not being used for migrated data between other data storage nodes within the storage network 100. Processing flow 500 may proceed from block 504 to block 506.
Block 506 (Assign Maximum Channel Transmission Rate) may refer to processor 123 assigning a maximum channel transmission rate for each of the available transmission channels based on predetermined parameters of a transmission channel. The predetermined parameters may include fixed values based on physical properties of the channel or some other factors that are not subject to adjustment. For example, the predetermined parameters may include a length or type of the available transmission channels. Processing flow 500 may continue from block 506 to block 508.
Block 508 (Calculate Fixed Transmission Channels) may refer to processor 123, for example, calculating a number of fixed transmission channels 405 of the available transmission channels to facilitate data migration from data storage node 122 to data storage node 172. The calculation may be based on the amount of data to be migrated divided by a transmission rate of each transmission channel. The number of fixed transmission channels 405 calculated may indicate the number of transmission channels required to migrate the data between data storage node 122 and data storage node 172. Processing flow 500 may continue from block 508 to block 510.
Block 510 (Transmit Data) may refer to an initiation of transmission of data by processor 123, from data storage node 122 to data storage node 172 via fixed transmission channels 405 of the available transmission channels. Processing flow 500 may continue from block 508 to block 510.
Block 512 (Detect Presence of Remaining Data) may refer to processor 123 detecting the presence of data remaining in data storage node 122 that has yet to be transmitted to data storage node 172, after initiating of transmission of data via fixed transmission channels 405. Processing flow 500 may continue from block 512 to block 514.
Block 514 (Select Random Transmission Channels and Transmit Remaining Data) may refer to processor 123 randomly selecting a number of random transmission channels 410 of the available transmission channels to transmit the detected remaining data, and transmitting the detected remaining data using at least one random transmission channel 410. Random selection of the number of random transmission channels 410 may be facilitated by a random number generator 125. The processor 123 may further be configured to assign a life cycle to each of the randomly selected ones of the random transmission channels 410 such that each random transmission channel is released after expiration of the life cycle thereof or after completion of transmission of the remaining data. The total number of random transmission channels 410 selected and the amount of time for completing migration of data between the data storage node 122 and the data storage node 172 using the fixed transmission channels 405 and the random transmission channels 410 is required to be equal to the time requirement as assigned by processor 123.
Thus, FIG. 5 shows an example processing flow executed by a processor of a data storage node.

Computing device 600 may be representative of at least one of a computing device at a user end for accessing cloud computing services; a computing device at a cloud provider e.g., cloud provider 155 or 157 depicted in FIG. 1; or at least one or more elements e.g., a processor of computing device 600 may be employed within a data storage node e.g., data storage node 122 of cluster 120 as depicted in FIG. 3. In a very basic configuration 602, computing device 600 typically includes one or more processors 604 and a system memory 606.

There is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. There are various vehicles by which processes and/or systems and/or other technologies described herein may be implemented, e.g., hardware, software, and/or firmware, and that the preferred vehicle may vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware.
The foregoing detailed description has set forth various embodiments of the devices and/or processes for system configuration 100 via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, several portions of the subject matter described herein may be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, can be equivalently implemented in integrated circuits, as one or more computer programs running on one or more computers, e.g., as one or more programs running on one or more computer systems, as one or more programs running on one or more processors, e.g., as one or more programs running on one or more microprocessors, as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and/or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies regardless of the particular type of signal bearing medium used to actually carry out the distribution. Examples of a signal bearing medium include, but are not limited to, the following: a recordable type medium such as a floppy disk, a hard disk drive, a CD, a DVD, a digital tape, a computer memory, etc.; and a transmission type medium such as a digital and/or an analog communication medium (e.g., a fiber optic cable, a waveguide, a wired communications link, a wireless communication link, etc.).
Those skilled in the art will recognize that it is common within the art to describe devices and/or processes in the fashion set forth herein, and thereafter use engineering practices to integrate such described devices and/or processes into data processing systems. That is, at least a portion of the devices and/or processes described herein can be integrated into a data processing system via a reasonable amount of experimentation. Those having skill in the art will recognize that a typical data processing system generally includes one or more of a system unit housing, a video display device, a memory such as volatile and non-volatile memory, processors such as microprocessors and digital signal processors, computational entities such as operating systems, drivers, graphical user interfaces, and applications programs, one or more interaction devices, such as a touch pad or screen, and/or control systems including feedback loops and control motors, e.g., feedback for sensing position and/or velocity; control motors for moving and/or adjusting components and/or quantities. A typical data processing system may be implemented utilizing any suitable commercially available components, such as those typically found in data computing/communication and/or network computing/communication systems.
The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.
Lastly, with respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an,” e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more;” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
