Definitions
- the invention relates to a management of the storage of data in a distributed storage space. Recall that a distributed storage system comprises several data processing devices forming a unified storage space.
- the storage devices are for example a computer, a radiotelephone, a reader / recorder, for example of the MP3 (Windows Media Audio) type, etc., and more generally any device capable of storing data.
- MP3 Windows Media Audio
- a user has different storage devices to store content. It has fixed electronic devices such as a personal computer, NAS hard drive (acronym for Network Attached Storage), and so on. It also has mobile electronic devices such as a radiotelephone, a camera, etc. Finally, it has electronic devices, most often servers, offering online storage spaces (flickR, box.net, ...) accessible via an Internet network.
- Each device is equipped with physical and software resources for locally manipulating data, manipulation including reading and writing data.
- a distributed storage system is formed of a plurality of devices to form a unified storage space.
- a user wishing to write or read content in a distributed storage system can do so on a device selected from the devices of the distributed storage system.
- a management module has the function of managing access to a content.
- the module stores a list of contents and the respective locations of the contents in the devices of the distributed storage system.
- a user wishing to manipulate content in the unified storage system visualizes the location or locations of the content through the management module, and selects a location at random.
- the inventors have found that no information on the devices forming the distributed storage system is available to judiciously select one or more devices that will be used for data manipulation.
- a device can for example be off and in this case the data can not be manipulated by this device, unless restarting. But the restart in question causes latency and energy consumption which is undesirable.
- the device can also be supplied with electricity but in the waking state. Standby of electronic equipment is widely used today to limit energy consumption. The standby is to no longer power the resources of the device concerned, resources can be a hard disk, a fan, a screen, etc.
- the problem is that restarting a device in a sleep state causes, like an off device, latency and undesirable power consumption.
- the invention improves the situation.
- the subject of the invention is a method of selecting at least one device for data manipulation, said at least one device being selected from among a plurality of devices forming a distributed storage space, characterized in that the selection of a device comprises a step of taking into account at least one technical information associated with the device.
- the selection of a device is therefore based on technical information relating to the devices comprising the distributed storage system. This technical information gives an indication of the capacity and / or performance of a device to perform a manipulation.
- the desired effect may be a reduction in power consumption due to data manipulation, or a decrease in latencies due to a restart of an off or standby device, or both effects at once. .
- devices of the distributed storage system may be in a plurality of respective electrical states involving a respective power consumption during data manipulation.
- a first variant of the method of the invention consists in taking into account the electrical state of the device.
- the invention will privilege data manipulation on the device which is use results in the lowest energy consumption, that is most often the ready-to-use device.
- the least power consuming device will be used for reading the content. Examples below will illustrate devices associated with a respective electrical state and the selection of one or more devices depending on the electrical state.
- a device is able to be in several states including a ready-to-use state.
- said at least one selected device is one whose electrical state is in a ready-to-use state.
- the overall energy consumption of the distributed storage system will be lower than when the selected device is in a sleep state or off.
- Each device is more or less efficient because of its hardware and software capabilities; each device is therefore able to perform a manipulation according to a respective speed of execution.
- the technical information is information related to the execution time of a manipulation by the device concerned. This feature makes it possible to favor a device capable of handling data as quickly as possible.
- the invention relates to a module that can be installed in a device, said module being capable, during a data manipulation request, of selecting, for data manipulation, at least one device among a plurality of devices forming a distributed storage space, characterized in that it comprises means for taking into account at least one technical information associated with the devices when selecting said at least one device.
- the invention relates to a computer system comprising a plurality of devices forming a distributed storage space, at least one device being able to be selected for the manipulation of data, characterized in that it comprises means for taking into account at least one technical information associated with the devices when selecting said at least one device.
- the invention also relates to a device characterized in that it comprises a module as defined above.
- the invention also relates to a computer program comprising code instructions which, when the program is executed, perform the steps of the method defined above, namely a step of taking into account at least one piece of information. technique associated with a device when selecting a device for data manipulation.
- FIG. 1 represents a computer system on which is illustrated a first exemplary embodiment illustrating a data storage management method according to the invention.
- FIG. 2 represents a computer system on which is illustrated a second exemplary embodiment illustrating a method of reading data according to the invention.
- Fig. 1 shows a SYS distributed data storage system comprising a plurality of DSP1-DSP4 devices on which data can be manipulated.
- a manipulation includes writing, reading data in a memory and that a writing includes the creation and modification of data.
- the SYS system comprises four devices interconnected via a network, said second network in the following description, forming a distributed storage space.
- a distributed storage system offers the possibility of distributing the data storage on one or a plurality of storage devices.
- the first device DSP1 corresponds to a home gateway type Livebox (trademark filed by the applicant); the second device DSP2 corresponds to an MP3 player / recorder able to read and record data type MP3; the third device DSP3 corresponding to a radiotelephone; and the fourth DSP4 device corresponding to a personal computer.
- each device comprises at least one processor and at least one memory capable of storing data.
- the DSPl gateway comprises a PRO1 processor, said first processor, connected to a memory MEM1, called the first memory, via a bus BUS1, said first bus.
- the DSPl gateway will not be used as storage means for data manipulation according to the method of the invention.
- the reader / recorder DSP2 comprises a processor PR02, said second processor, connected to a memory MEM2, said second memory, via a bus BUS2, said second bus.
- the radiotelephone DSP3 comprises a processor PR03, said third processor, connected to a memory MEM3, said third memory, via a bus BUS3, said third bus.
- the computer DSP4 comprises a processor PR04, said fourth processor, connected to a memory MEM4, said fourth memory, via a bus BUS4, said fourth bus.
- the gateway DSP1 is connected to both a first network RES1 and the second network RES2.
- the first network RES1 is for example the Internet network.
- the second RES2 network used in our example is a WiFi wireless network.
- Each device DSP1 to DSP4 is therefore equipped with means for transmitting and receiving data for transmitting and receiving data according to the 802.11 standard.
- a device can be in three states. A first ON state in which the device is ready for use, a second VLL state in which the device is in a sleep state and a third OFF state in which the device is turned off.
- the exemplary embodiment is limited to three electrical states however other states can naturally be taken into account for the implementation of the invention. The number of states could be less than or greater than three. Also, we will not go into the detail of each state because without interest for the presentation of the invention. It should also be noted that a ready-to-use device is a device powered by energy, ready for operation and having no hardware and / software resources in the waking state.
- the method of the invention preferably requires an energy consumption budget of each device forming the distributed storage system.
- a device in the ON state that is to say ready to use consumes more energy than a device in the standby state VLL which consumes itself more energy than a device in the OFF state.
- Conso (ON) represents the consumption of a device in the ready-to-use ON state
- VLL Conso
- a counter-example is that of a server in the state of standby and a reader / recorder type MP3 in the ready-to-use state; in this configuration, the server in question in the standby state can consume more energy than a reader / recorder ready for use.
- ⁇ , ⁇ , ⁇ are integers and the symbol "+" denotes an addition.
- the system will, following the selection, always have the same number of devices in the system. ON ready state, the same number of devices in the standby state VLL and the same number of OFF devices.
- the global consumption referred to as the first consumption noted below Consl, can be written using the following mathematical relationship
- Consl X (Conso (ON)) + Y (Conso (VLL)) + Z (Conso (OFF))
- Cons3 (X + 1) (Conso (ON)) + Y (Conso (VLL)) + (Z-1) (Conso (OFF))
- the selection of a device for data manipulation comprises a step of taking into account at least one technical information associated with the device.
- the device that is chosen for data manipulation is selected according to the power consumption of said device for performing data manipulation.
- a management module MOT has the function of managing this selection.
- a device in a ready-to-use state will be preferred over devices in a sleep state or off. Also, if the SYS system does not include devices in the ready-to-use ON state, a device in the standby state VLL will be preferred over an off OFF device. It has been considered in the foregoing that a device remaining in the same state will consume less power than a state changing device to go from the standby state or off to the ready-to-use state.
- this module MOT is located in the first device DSP1 under the control of the first processor PRO1; however, the location of this device can be any.
- a first step data from the first network RES1 are received by the gateway DSP1.
- the nature of the data can be any.
- this data is CNT music content.
- the received signal thus includes at least two parameters, namely a write command WR and the content CNT, (..., WR, CNT, ...), the suspension points indicating that other parameters can be added such as gateway ID, etc. These other parameters are of no importance for the disclosure of the invention.
- the first processor PRO1 receives the signal including the write command WR and the content CNT, and transmits a command to the module MGT to determine the device or devices on which the CNT content can be stored.
- the MGT module knowing the electrical state in which each device is located, determines the storage device (s) to be used which will consume the least energy.
- the MGT module will favor a write on the radiotelephone PSP3 because it is in a ready state ON. In the following, it is assumed that a writing is always performed on two devices so as to improve the availability of data thereafter. When the radiotelephone has been selected, there remain two devices that can be selected, namely the second device and the fourth device. However, by applying the considerations outlined above, the module will favor handling on the DSP3 reader / recorder because it is in the standby state.
- the MOT module selects the DSP3 radiotelephone and the DSP2 reader / recorder.
- the first processor PRO1 receives the selection made by the module MOT.
- the first processor PRO1 transmits a write command to both the radiotelephone DSP3 and the reader / recorder DSP2, respectively.
- the radiotelephone DSP3 and the reader / recorder DSP2 execute the respective writing command.
- a TAB lookup table is created in which an identifier of the CNT content and the location of the CNT content in the distributed storage system are stored.
- the table includes the identifier of the content, the identifier of the radiotelephone DSP3 and the identifier of the reader / recorder DSP2.
- this first phase is followed by a second reading phase of the same content.
- the DSP4 computer is turned on and that it is from this computer that the request for reading the content will be sent.
- the DSP2 reader / recorder and the DSP3 radiotelephone are in the same state as in the previous example, namely in the standby state and in the operating state, respectively.
- This second phase includes the following steps:
- a user requires access to the CNT content.
- the request in question is transmitted to the module MOT managing access to the content.
- the MGT module receives a signal including a read command RD and a CNT content identifier for which a read access is requested, in FIG. 2, the signal in question is referenced (.. ., RD, NTC ).
- the MGT module consults the TAB correspondence table, and identifies the device or devices on which the CNT content is stored.
- the devices concerned are the DSP2 reader / recorder and the DSP3 radiotelephone.
- the MGT module consults the state of the devices identified in the third step and selects a device according to its state. Based on the above considerations, the MGT module will favor a reading through the PSP3 radiotelephone because it is in a ready-to-use ON state.
- the MGT module permanently has a state of each device. This state is updated periodically either on request of the MGT module or on receipt of information from a device having changed state or about to change state. For example, the module may periodically transmit signals to the devices composing the distributed storage system and if the module does not receive a response from a device, the module considers that the device in question is in the standby state VLL OFF or OFF.
- Each device may also be equipped with a software module capable of transmitting to the management module a change of state or a state change prediction.
- the preceding embodiments are related to energy consumption. Another embodiment could consist in selecting a device as a function of the estimated execution time of a manipulation by the device concerned. This makes it possible to favor a device capable of handling data more quickly than other devices of the distributed storage system.
