Description

PCIe and SATA compatible copying device

Technical Field

The present disclosure relates to a solid state disk copying apparatus, and more particularly, to a PCIe-SATA compatible solid state disk copying apparatus capable of performing batch copy operations of different working specifications mixed with NVMe signals and SATA signals.

Background

The general solid state disk copying is usually performed by using a PCI-E (peripheral component interconnect-express) connection interface provided by a PCI-E control card of a PC (personal computer). However, this method requires the cooperation of management software, and it cannot process many solid state disks at a time, i.e. cannot perform a large number of copy operations.

In addition, the number of copies of a batch of solid state disks may be required differently for different customers. In order to meet the requirements of different customers, manufacturers of solid state disk copy devices must provide solid state disk copy devices with different specifications. However, when there are many different specifications to be met, the overall cost of the manufacturer of the solid state disk copy device is greatly increased.

In addition, the solid state disk may adopt NVMe (non-volatile memory) signals or SATA (serial advanced technology attachment) signals, and a user often cannot determine that the solid state disk adopts the NVMe signals or the SATA signals, so that a copy operation cannot be smoothly performed on a solid state disk copy device (adopting the specification of the NVMe signals or the SATA signals). For example, if a solid state disk employs NVMe signals and a solid state disk copying device employs SATA signals, a user cannot copy the solid state disk in the solid state disk copying device.

To solve the foregoing problems, there is a need in the art for a novel PCIe and SATA compliant copy apparatus.

SUMMERY OF THE UTILITY MODEL

An objective of the present disclosure is to disclose a PCIe-SATA compatible copying apparatus, which can perform an NVMe/SATA signal interpretation operation through an NVMe/SATA signal interpretation module, so that an operator can perform a PCIe-SATA compatible copying operation on the PCIe-SATA compatible copying apparatus of the present disclosure without knowing that the specification of the solid state disk is the NVMe signal or SATA signal.

Another objective of the present disclosure is to disclose a PCIe-SATA compatible copy apparatus, which can automatically determine whether each solid state disk employs an NVMe signal or an SATA signal in a batch copy operation, so as to complete batch copy operations with different working specifications mixed with the NVMe signal and the SATA signal.

As shown in fig. 1-3, a PCIe-SATA compatible copy apparatus 100 includes a plurality of copy units 110, an information display 120, and a set of

keys

131 and 132, wherein each copy unit 110 has a PCI-E interface 111, a SATA interface 112, a circuit board 113, a serial input connection 114, and a serial output connection 115, and the plurality of copy units 110 are connected in series with each other by a plurality of connection lines (through the interconnection of the serial output connection 115 of the previous copy unit 110 and the serial input connection 114 of the next copy unit 110).

As shown in fig. 3, the circuit board 113 has a control chip 1131, and a serial interface 1132, a PCI-E interface circuit 1133a, a SATA interface circuit 1133b, a display interface 1134, a button circuit 1135, an indicator light driving circuit 1136 and a memory 1137 electrically coupled to the control chip 1131, wherein the memory 1137 stores an NVMe/SATA signal interpretation module 1137 a.

The control chip 1131 may be coupled to the information display screen 120 (which may be formed by a liquid crystal display) through the display interface 1134 to provide information of the operation status, and coupled to the key circuit 1135 and the keys 131-132 (which include a start key and a plurality of selection keys) to receive key input.

The control chip 1131 is electrically coupled to the serial input connection terminal 114 and the serial output connection terminal 115 through the serial interface 1132, respectively; coupled to PCI-E interface 111 via PCI-E interface circuitry 1133 a; coupled to SATA interface 112 via SATA interface circuitry 1133 b; and the NVMe/SATA signal interpretation module 1137a is executed by the memory 1137 to perform an NVMe/SATA signal interpretation operation.

In operation, the control chip 1131 reads a working signal of a solid state disk through the PCI-E interface circuit 1133a and the PCI-E interface 111 or through the SATA interface circuit 1133b and the SATA interface 112, and then performs the NVMe/SATA signal interpretation operation to determine whether the working signal is an NVMe signal or a SATA signal, so as to correctly access the solid state disk.

That is, the operator does not need to know that the specification of the solid state disk is NVMe signals or SATA signals, and can perform the copy operation on the PCIe and SATA compatible copy apparatus of the present disclosure.

In addition, the control chip 1131 may drive the plurality of indicator lamps through the indicator lamp driving circuit 1136 to indicate an operation state of a corresponding copy unit 110.

In addition, the PCIe and SATA compatible copy apparatus of the present disclosure may further include a serial input connection 114 and a serial output connection 115 on the casing 100, which are respectively used as an expansion input connection and an expansion output connection.

In the first embodiment, as shown in FIG. 4a, by pressing the keys 131 and 132 (including a start key and a plurality of selection keys), the present disclosure can copy the primary copy data from the PCI-E solid state disk 200 plugged in a first PCI-E interface 111 to the PCI-E

solid state disk

201 and 205 plugged in other PCI-E interfaces 111, thereby completing a batch of copy operations.

In the second embodiment, as shown in FIG. 4b, by pressing the button 131-.

In the third embodiment, as shown in fig. 4c, by pressing the keys 131 and 132 (including a start key and a plurality of selection keys), the present disclosure can copy the primary copy data from the SATA hard disk 300 plugged in a first SATA interface 112 to the SATA

hard disks

301 and 305 plugged in the other five SATA interfaces 112, thereby completing a batch copy operation.

In the fourth embodiment, as shown in FIG. 4d, by pressing the keys 131-132 (including a start key and a plurality of selection keys), the present disclosure can copy the primary copy data from the PCI-E solid state disk 200 plugged in a first PCI-E interface 111 to the SATA solid state disks 301-305 plugged in five SATA interfaces 112, thereby completing a batch of copy operations.

In addition, the PCIe-SATA compatible copying device can execute a data comparison program after executing a batch of copying operations to ensure the correctness of data copying.

In addition, because the functions of the present disclosure can be realized by programming a control chip, the PCIe and SATA compatible copy apparatus of the present disclosure can satisfy the requirement of the user for batch copying of the solid state disks without the support of a PC. Moreover, since the control chip of the present disclosure only needs to implement the copy function of the solid state disk in the control portion of the PCI-E interface, other functions (such as a display card, an audio card, a network card, etc.) of a general PCI-E controller can be omitted, and the robustness and reliability of the PCIe and SATA compatible copy device of the present disclosure can be further improved.

With the design disclosed in the foregoing, the present disclosure has the following advantages:

1. the PCIe-SATA compatible copying device can perform NVMe/SATA signal interpretation operation through an NVMe/SATA signal interpretation module, so that an operator can perform mutual-compatibility copying operation on the PCIe-SATA compatible copying device without knowing that the specification of the solid state disk adopts NVMe signals or SATA signals.

2. The PCIe-SATA compatible copying device can automatically judge whether each solid state disk adopts NVMe signals or SATA signals in batch copying operation, so that batch copying operation of different working specifications mixed with the NVMe signals and the SATA signals is completed.

3. The PCIe and SATA compatible copying device can realize the PCI-E solid state disk copying function through the control chip, independently perform data copying operation without the support of a PC, and realize the PCI-E solid state disk copying function in a simplified mode compared with a common PCI-E controller.

4. The PCIe-SATA compatible copying device can adjust the number of the copying units in a serial connection mode so as to meet the number requirement of various batches of copies.

5. The parent source data required by the data copying operation of the PCIe-SATA compatible copying device can be provided by an external computer, or provided by a solid state disk inserted in a first copying unit, or provided by a memory stored in the solid state disk copying device.

6. The PCIe-SATA compatible copying device is provided with a plurality of independently replaceable copying units, so that local faults of the copying device can be conveniently eliminated.

7. The PCIe and SATA compatible copying device can compare the copied data of the solid state disk to ensure the correctness of data copying.
