Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of method of operation of solid state hard disc, and a kind of SSD that has Ethernet interface is provided, and has realized the direct access network based on ethernet of SSD.
As shown in Figure 1, the flow chart for the method for operation of a kind of solid state hard disc of the embodiment of the invention comprises:
Step S101 receives ethernet frame by Ethernet interface.
Step S102 according to ethernet frame, operates solid state hard disc.
Wherein, solid state hard disc being operated the non-volatile memory medium that is specially in the solid state hard disc operates.
The method of operation of above-mentioned solid state hard disc, according to the ethernet frame that receives solid state hard disc is operated, a kind of SSD that has Ethernet interface is provided, and mode by built-in control system among the SSD, realized that SSD directly by Ethernet transmission and data download, has greatly improved uploading and speed of download of data.
In the embodiment of the invention, according to ethernet frame, the flow process that solid state hard disc is operated specifically comprises as shown in Figure 2:
Step S201 carries out TCP (Transmission Control Protocol, transmission control protocol)/IP (Internet Protocol, Internet Protocol) decapsulation to ethernet frame, obtains the operational order to solid state hard disc.This decapsulation is specifically as follows: the TCP/IP head of the ethernet frame that receives is removed, obtain the operational order to solid state hard disc in the ethernet frame.
Step S202 will resolve to corresponding executable command to the operational order of solid state hard disc.
Step S203 operates the non-volatile memory medium in the solid state hard disc according to executable command.
Step S204 receives the result that the non-volatile memory medium in the solid state hard disc is operated.
Step S205 carries out the TCP/IP encapsulation to the result of aforesaid operations and obtains ethernet frame, and sends this ethernet frame.
Wherein, the result who operates is carried out the TCP/IP encapsulation be specially: the TCP/IP head is gone up in the operating result encapsulation that receives, transmitted to be fit to Ethernet.
As shown in Figure 3, be the structure chart of a kind of solid state hard disc of the embodiment of the invention, comprise Ethernet interface 31, control module 32 and non-volatile memory medium 33,
Ethernet interface 31 is used to receive ethernet frame;
As shown in Figure 4, control module 32 can comprise:
Wherein, control module 32 can also comprise:
The result receives submodule 324, is used to receive the result that 323 pairs of non-volatile memory mediums of command execution submodule are operated;
Wherein, decapsulation submodule 321 and encapsulation submodule 325 are positioned on the interface control chip 41 of solid state hard disc;
Non-volatile memory medium 33 is specifically as follows Flash chip or SDRAM.
With the read data order is example, the operation that solid state hard disc carries out is specially: Ethernet interface 31 receives after the ethernet frame of main frame transmission, 321 pairs of these ethernet frames of decapsulation submodule carry out decapsulation, obtain the read data order that this ethernet frame carries, command analysis submodule 322 is an executable command with this read data command analysis, command execution submodule 323 reads the data of storing in the non-volatile memory medium of solid state hard disc according to this executable command, the data that read are sent to the result receive submodule 324, encapsulation submodule 325 couples of results receive the data that submodule 324 receives and carry out the TCP/IP encapsulation, obtain ethernet frame, and ethernet frame is sent to main frame by Ethernet interface 31.
Be example with the write data order again, the operation that solid state hard disc carries out is specifically as follows: Ethernet interface 31 receives after the ethernet frame of main frame transmission, 321 pairs of these ethernet frames of decapsulation submodule carry out decapsulation, obtain the write data order that this ethernet frame carries, command analysis submodule 322 is an executable command with this write data command analysis, and command execution submodule 323 obtains the data to be written of carrying out after TCP/IP encapsulates according to this executable command to main frame.After the data to be written after getting access to encapsulation, the data to be written of 321 pairs of encapsulation of decapsulation submodule are carried out decapsulation, and command execution submodule 323 writes in the non-volatile memory medium of solid state hard disc according to the data to be written of above-mentioned executable command after with decapsulation again.At this moment the result that non-volatile memory medium is operated can be the state of memory cell in the non-volatile memory medium, for example: storage unit space deficiency or memory cell write-protect etc.; The result of aforesaid operations can also be command execution results, and for example: write operation is finished or write operation failure etc.Receive after submodule 324 receives operating result in the result, 325 pairs of these operating results of encapsulation submodule carry out the TCP/IP encapsulation, obtain ethernet frame, and by Ethernet interface 31 this ethernet frame are sent to main frame.
As shown in Figure 5, this solid state hard disc can also comprise CPU (Central Processing Unit, CPU) 43, is responsible for the related operation when non-volatile memory medium 33 operated.
This solid state hard disc can also comprise buffer memory 44, is used for the data that buffer memory carries out operating process to the non-volatile memory medium 33 of solid state hard disc.
Above-mentioned solid state hard disc, control module 32 is operated non-volatile memory medium 33 according to the ethernet frame that Ethernet interface 31 receives.Thereby, a kind of SSD that has Ethernet interface is provided, realized the direct access network based on ethernet of SSD.
Above-mentioned module can be distributed in a device, also can be distributed in multiple arrangement.Above-mentioned module can be merged into a module, also can further split into a plurality of submodules.
