Description
Technical field
The utility model relates to the test of the multi-diskbit NVMe backboard in server more particularly to a kind of NVMe back plate testings
Device.
Background technique
With the development of information technology, the safety of personal data business and data property is increasingly by the weight of people
Depending on, the main component that data storage function is undertaken in storage server is SSD (Solid State Drives solid state hard disk),
And it is attached between SSD and server master board further through hard disk backboard.Therefore, the performance of hard disk backboard is to storage server
For it is extremely important.As user data amount of access is more and more frequent, it is impossible to meet user's frequencies for traditional hard disk backboard
The requirements for access of numerous high speed produces the NVMe (Non-Volatile for meeting high speed access demand with the development of information technology
Memory express nonvolatile memory standard) backboard.
Whether the function of needing to test NVMe backboard is normal, and current test method is that a piece of expansion is inserted on server master board
Piece or RAID card (RAID card) are opened up, backboard is then connected by connector, then meet multiple SSD, since NVMe is based on PCIe
Agreement need after entering device to check whether that SSD can be found so corresponding test method needs the support of operating device
Hard disk needs cycle power to change next NVMe backboard after the completion of test, if related protocol cannot be loaded by not restarting, thus
SSD hard disk can not be found, and normal shutdown and booting reboot into operating device interface and require the regular hour, low efficiency
Under.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of NVMe back plate testing device, mention significantly
High testing efficiency.
The technical solution of the utility model is as follows: providing a kind of NVMe back plate testing device, comprising: the first connection cables,
Conversion unit of protocol, the second connection cables, connector and SSD, first connection cables one end are connect with server master board,
The other end is connect with conversion unit of protocol, and second connection cables one end is connect with conversion unit of protocol, the other end with connect
Device connection, the connector connect with tested backboard, and the SSD is connect with tested backboard, first connection cables for based on
The TYPE A-C type or TYPE C-C molded line cable, the conversion unit of protocol of USB3.1 Gen2 specification are converted to USB3.1
PCIe protocol.
Further, the conversion unit of protocol uses chip ASM2362.
Further, the connector is MINI SAS HD high speed connector.
Further, second connection cables are the direct-connected line of MINI SAS HD.
Further, the conversion unit of protocol further includes a data indicator light, judges data according to the data indicator light
Interaction mode.
Using the above scheme, the utility model is connect by the first connection cables with server, carries out data communication, data
After signal is converted into PCIe signal by conversion unit of protocol, pass through the second connection cables and connector and tested backboard phase
Even, tested backboard meets SSD, and the final data interaction realized to SSD can embody the quality of tested backboard from SSD.This is practical
It is novel to facilitate plug using USB, the characteristics of plug and play, promotion testing efficiency, and high-frequency switching on and shutting down are reduced to server
The damage probability of mainboard.
Detailed description of the invention
Fig. 1 is the functional block diagram of the utility model.
Fig. 2 is the connection circuit diagram of the first connection cables of the utility model.
Fig. 3 is the circuit diagram of the utility model conversion unit of protocol.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of NVMe back plate testing device, comprising: the first connection cables, agreement turn
Change unit, the second connection cables, connector and SSD.First connection cables one end is connect with server master board, the other end
It being connect with conversion unit of protocol, second connection cables one end is connect with conversion unit of protocol, and the other end is connect with connector,
The connector is connect with tested backboard, and the SSD is connect with tested backboard, and the quality of tested backboard can be embodied from SSD.
Fig. 2 is the connection line figure of the first connection cables, and first connection cables are to be standardized based on USB3.1 Gen2
TYPE A-C type or TYPE C-C molded line cable, i.e. first connection cables one end are TYPE A type, and the other end is TYPE c-type, or
Both ends are all TYPE c-types.
Referring to Fig. 3, USB3.1 is converted to PCIe protocol by the conversion unit of protocol, conversion unit of protocol is mainly by core
Piece ASM2362 composition, it supports USB3.1Gen2 input, is converted to PCIe Gen3 X2, is mainly used for the bridge joint of NVMe SSD
Conversion, is integrated with CC logic identification circuit, does not need again plug-in.
Second connection cables are the direct-connected line of MINI SAS HD, and the connector is that MINI SAS HD high speed connects
Conversion unit of protocol is connected by device by the second connection cables and connector with tested backboard.
The conversion unit of protocol further includes a data indicator light, which is LED light, is sentenced according to the data indicator light
The interaction mode of disconnected data, data indicator light can be always on when seeking disk, and when there is reading and writing data, the flashing of data indicator light is read
Writing complete rear data indicator light is also to be always on.
In conclusion the utility model is connect by the first connection cables with server, data communication, data-signal are carried out
After being converted into PCIe signal by conversion unit of protocol, it is connected by the second connection cables and connector with tested backboard, quilt
It surveys backboard and meets SSD, the final data interaction realized to SSD can embody the quality of tested backboard from SSD.The utility model
Facilitate plug using USB, the characteristics of plug and play, promotes testing efficiency, and reduce high-frequency switching on and shutting down to server master board
