In field of data storage, in order to ensure the reliability of data, when storing to normal data, it will usually generate
For the protection data of normal data, the such as Backup Data of the normal data, these protection data have provisional, life cycle
It is shorter, therefore the ephemeral data that is otherwise known as.For example, data backup of device A when by Data Migration to equipment B to migrating,
Avoid in data migration process because link failure causes loss of data, once data are successfully migrated to equipment B, device A
Backup Data will be deleted.In practical situation, for many scenes ephemeral data, the such as duplication of file system, file can be produced
The shearing of system, file system between devices synchronous, etc., embodiment of the present invention here differs an illustration.
In prior art, storage device is identical to the storage mode of above-mentioned ephemeral data and the storage mode of normal data,
First then ephemeral data, is write into SSD by ephemeral data write caching (Cache) from Cache.But, due to the nonce
According to life cycle it is short, at the end of its life cycle, storage device again wipes it from SSD, it is seen then that for ephemeral data
Write operation must cause SSD using wasting, the life-span for causing SSD reduces.In addition in actual motion, above-mentioned ephemeral data
Enormous amount, if using storage mode of the prior art, SSD will be caused continually to write shorter interim life cycle
Data, and continually at the end of ephemeral data life cycle the ephemeral data is wiped, the service life for causing SSD falls sharply.

Data are marked.
In above-mentioned technical proposal, before caching 13 is filled with, ephemeral data is stored among caching 13, only in caching
13 when being filled with, and just still unclosed ephemeral data life cycle is write into storage dishes 14 from caching 13, due to the life of ephemeral data
The duration of cycle of deposit is shorter, many ephemeral datas cache 13 be not filled with when life cycle terminate so that storage device can not
With the ephemeral data write storage dish 14 for being over these life cycles, the number of times that storage dish 14 writes data is reduced.
On the other hand, due to the ephemeral data being over life cycle is write into storage dish 14 without above-mentioned, storage dish 14 is also not required to
Erasing operation is carried out to these ephemeral datas.It can be seen that, after aforesaid way, storage dish 14 need to write and facing of need to wiping
When data quantity reduce, and then the service life of storage dish 14 can be extended.

Fig. 2 is the schematic flow sheet of storage ephemeral data method provided in an embodiment of the present invention, and the method includes following step
Suddenly：
Step 201, storage device is marked to the ephemeral data for needing the Cache of write storage device.
Specifically, the ephemeral data can be what storage device itself was generated, and such as storage device is applied not only to storage reception
Data, can also to receive data process, generate ephemeral data, the ephemeral data can be receive data it is standby
Part, storage device is provided out value-added service by generating the ephemeral data.In this case, storage device can generated
The ephemeral data is marked during the ephemeral data.
In another kind of implementation, storage device is not that the ephemeral data is marked when ephemeral data is generated,
But before Cache is write data into, need the data for writing Cache to be judged for each, judge that whether it be
Ephemeral data, is if so, then marked.This mode is applied to the situation that ephemeral data is generated by storage device,
It is that storage device receives the situation for obtaining from from the other equipment (such as main frame) of connection suitable for ephemeral data.
Storage device can be marked using various ways to the data, and for example, storage device can carry the number
According to memory pages on addition show the data be ephemeral data mark；Again for example, storage device can be preserved in the buffer
One temporary data table, preserves the mark of all ephemeral datas in the form；Again for example, storage device can be in the data
Original position or end position addition show the attribute information that the data are ephemeral data.
Labeled ephemeral data is write Cache by step 202, storage device.
Step 203, the ephemeral data that Cache is filled with and is labeled life cycle not yet at the end of, will be labeled
The storage dish of ephemeral data write storage device.
In above-mentioned technical proposal, storage device is only when caching is filled with just by still unclosed ephemeral data life cycle
From caching write storage dish, because the duration of the life cycle of ephemeral data is shorter, many ephemeral datas are not when being filled with
Life cycle terminates so that storage device can write storage dish without the ephemeral data for being over these life cycles,
Reduce the number of times that storage dish writes data.On the other hand, due to without the above-mentioned ephemeral data for being over life cycle
Write storage dish, storage dish carries out erasing operation also without to these ephemeral datas.It can be seen that, after aforesaid way, storage
The quantity of the ephemeral data that disk need to write and need to wipe is reduced, and then can extend the service life of storage dish.
Optionally, in the embodiment of the present invention, storage device includes SSD and non-SSD storage dishes, with reference to Fig. 3, step 203
During enforcement, comprise the steps：
Step 2031：The data that Cache is filled with and is labeled life cycle not yet at the end of, storage device will be marked
The data of note write non-SSD storage dishes.
Specifically, non-SSD storage dishes can have various implementations, such as mechanical hard disk, solid-state hybrid hard disk (Solid
State Hybrid Drive, SSHD).
In this implementation, by the store tasks that ephemeral data is undertaken by non-SSD storage dishes, the write of SSD is reduced
Number of times and erasing times, improve the life-span of SSD.
Optionally, in the embodiment of the present invention, storage device is stored in labeled data when Cache is not filled with
In Cache.
Optionally, in the embodiment of the present invention, with continued reference to Fig. 3, the method for storing ephemeral data also comprises the steps：
Step 204, when Cache is not filled with and at the end of the life cycle of labeled data, storage device is from Cache
It is middle to delete labeled data.
Specifically, storage device determines whether the life cycle of labeled data (that is, ephemeral data) terminates, including many
Implementation is planted, for example, when the ephemeral data is the data that storage device is received from external equipment, storage device can be from this
External equipment is received and indicates that storage device deletes the instruction of the ephemeral data, storage device when the instruction is received, it is determined that this faces
When data life cycle terminate.Again for example, storage device receives the life cycle for showing the ephemeral data from the external equipment
The message of end, storage device determines that the life cycle of the ephemeral data terminates according to the message.Again for example, in the ephemeral data
When being generated by storage device oneself, storage device can arrange a timer for the ephemeral data, reach in the timing of the timer
During to preset duration, storage device determines that the life cycle of the ephemeral data terminates.Again for example, set by storage in the ephemeral data
During standby oneself generation, storage device can determine the life of the ephemeral data when the ephemeral data role has finished
Cycle of deposit terminates.
In above-mentioned technical proposal, storage device can delete what the life cycle in caching terminated before caching is filled with
Ephemeral data, on the one hand, so that storage device, by this partial data write storage dish, reduces the write data of storage dish without the need for again
Number of times, extends its life-span.On the other hand, ephemeral data is removed from the cache so that caching can cache more new numbers
According to the ability of the data storage of increase caching.
Optionally, in the embodiment of the present invention, storage device is removed from the cache batch when caching is filled with, just and deletes existence
The ephemeral data that cycle has terminated.This implementation carries out the deletion of ephemeral data by concentrating, and can mitigate storage device and delete
Except the burden of data.
Optionally, in the embodiment of the present invention, storage device when whether judge a certain data is ephemeral data, with specific reference to
The attribute information of the data is judging whether the data are ephemeral data.For example, storage device can be according to generating the data
Program module judging whether it is ephemeral data, such as, and data by storage device copy services subsystem
When (Replication Service Sub-System, RSS) is generated, ephemeral data is determined that it is.Again for example, storage device can
Ephemeral data is determined whether it is with the data object belonged to according to data, such as, is in the data object belonging to data
During the application entity of corresponding data backup, ephemeral data is determined that it is.Again for example, it is the equipment from outside storage device in data
When place receives, storage device can be come according to the information of input/output (input/output, the I/O) interface for receiving the data
Judge whether the data are ephemeral data.In this implementation, ephemeral data can be efficiently determined, and then can be to it
Labelling, is easy to store it to by the way of step 204 using abovementioned steps 201.
Optionally, in the embodiment of the present invention, storage device can apply to storage area network (Storage Area
Network, SAN), as the memory node in SAN.Storage device can also be applied to network attached storage (Network
Attached Storage, NAS) etc. among other computer memory systems, the embodiment of the present invention differs an illustration.
Optionally, when storage device is applied among SAN, storage device can set as main storage device or from storage
Standby, ephemeral data can be file synchronization among by main storage device to produced protection during the storage device
The data of property.For example, after the data on main storage device are modifiable by the user, from storage device can the synchronous modification, from depositing
Storage equipment can adopt the mode of Copy on write (Copy On Write, COW) to modify data, specifically, storage device
Old data can be read, in saving it in caching, the old data are ephemeral data.Using side provided in an embodiment of the present invention
Method, the old data are stored among caching, and are not written into SSD, only when caching is filled with, are just write the old data
Non- SSD storage dishes.

The application example of storage ephemeral data is illustrated.LUN (Logical Unit Number, LUN) mould shown in Fig. 4
The functional module that block, value-added service module, mark module are marked off all in accordance with the function of controller.Include in controller multiple
During control chip, above-mentioned LUN modules, value-added service module and mark module can be realized by same control chip, it is also possible to
Realized by different control chips respectively.The application example of the storage ephemeral data shown in Fig. 4 comprises the steps：
Step 301, the interface of storage device receives write data requests from external equipment, and the write data requests are write including request
The data for entering.
Step 302, LUN modules respond the write data requests, are the data application memory pages resource of request write.
Step 303, LUN modules judge that the data of the request write need value-added service resume module, send it to
Value-added service module.
Step 304, value-added service module is processed the data of request write, obtains value-added service data.
Step 305, value-added service module is by value-added service data and the data is activation of request write to mark module.
Step 306, mark module determines that value-added service data are ephemeral data, is marked.
The data of value-added service data and request write are returned LUN modules by step 307, mark module.
The data write of value-added service data and request write is cached Cache by step 308, LUN modules.
Step 309, caches the data write SSD storage dishes of request write.
Step 310, is buffered in when itself being filled with and for value-added service data to write non-SSD storage dishes.
In above-mentioned technical proposal, storage device can be marked to ephemeral data, and only when caching is filled with
By life cycle still unclosed ephemeral data from caching write storage dish, due to ephemeral data life cycle duration compared with
Short, many ephemeral datas terminate the life cycle when not being filled with so that storage device can be without by these life cycles
The ephemeral data write storage dish being over, reduces the number of times that storage dish writes data.On the other hand, due to not above-mentioned
The ephemeral data being over life cycle is write into storage dish, storage dish carries out erasing behaviour also without to these ephemeral datas
Make.It can be seen that, after aforesaid way, the quantity of the ephemeral data that storage dish need to write and need to wipe is reduced, and then can be prolonged
