[0055] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] The terms "first" and "second" in the description and claims of the present invention may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0058] The following will describe the present invention in conjunction with Figures 1-8 .

[0059] Figure 1 FIG. is one of the schematic diagrams of the storage resource pool structure provided by an embodiment of the present invention. As Figure 1 shown, the storage resource pool structure includes: an optoelectronic conversion module 101, a connection module 102, a backplane 103, a hard disk 104, and a dynamic management module 105.

[0060] Among them, the optoelectronic conversion module 101 is connected to a high-speed serial bus switch board through an optical fiber. Optionally, the high-speed serial bus switch board is a PCIE SW (peripheral component interconnect express switchboard) board. PCIE (peripheral component interconnect express) is a high-speed serial computer expansion bus standard.

[0061] The optoelectronic conversion module 101 is configured to convert a first optical signal from the high-speed serial bus switch board into a high-speed serial bus signal. Optionally, the high-speed serial bus signal is a PCIE signal, or convert an electrical signal from the hard disk 104 into a second optical signal.

[0062] In order to solve the problem that it is difficult to expand the large capacity of storage resources in the prior art, the present invention decouples each functional module of the server and pools the storage resources, realizing flexible configuration of storage resources. It can be understood that by decoupling each functional module of the server and pooling the storage resources, there must be a problem that the high-speed serial bus trace is extremely long between the CPU and the storage resource pool. When using a cable to transmit an electrical signal, the electrical signal attenuates very quickly and the signal transmission quality is relatively low. The present invention uses an optical fiber to replace the cable and realizes the mutual conversion of high-speed serial bus signals and optical signals through an optical transmission network, which can solve the problem of the extremely long high-speed serial bus trace between the CPU and the storage resource pool and improve the signal transmission quality.

[0063] The connection module 102 is used to connect the photoelectric conversion module 101 and the backplane 103. The connection module 102 is configured to transmit the high-speed serial bus signal output by the photoelectric conversion module 101 to the hard disk 104 connected to the backplane 103, or input the high-speed serial bus signal output by the hard disk 104 connected to the backplane 103 into the photoelectric conversion module 101.

[0064] A plurality of the hard disks 104 are inserted on the backplane 103. Optionally, eight hard disks 104 are inserted on each backplane 103.

[0065] The photoelectric conversion module 101 is further configured to detect the first optical signal or the second optical signal and output a photoelectric detection signal.

[0066] The dynamic management module 105 is configured to determine the access status of the high-speed serial bus signal based on the photoelectric detection signal output by the photoelectric conversion module 101, analyze the access status, and control the power-on or power-off of the power state of the hard disk 104 by outputting high and low levels, so as to dynamically manage the power consumption of the hard disk 104, reduce the energy consumption of the storage resource pool, and facilitate the energy-saving control of the storage resource pool.

[0067] In the embodiment of the present invention, by pooling storage resources, large-capacity expansion of storage resources can be achieved to meet scenarios with high requirements for storage resources. Through the photoelectric conversion module in the storage resource pool structure, the mutual conversion between the high-speed serial bus signal and the optical signal is realized based on the optical transmission network, which can solve the problem of ultra-long routing of the high-speed serial bus between the CPU and the storage resource pool, improve the quality of signal transmission, and make the distance between the host and the storage resource pool almost unlimited. At the same time, the dynamic management module in the storage resource pool structure determines the access status of the high-speed serial bus signal through the photoelectric detection signal, and dynamically manages the power consumption of the hard disk based on the access status, reducing the energy consumption of the storage resource pool and facilitating the energy-saving control of the storage resource pool.

[0069] Among them, the receiver 201 is used to amplify or attenuate the first optical signal from the high-speed serial bus switch board, adjust the first optical signal to an appropriate optical power range, and send the processed first optical signal to the first arrayed waveguide grating 202. The first arrayed waveguide grating 202 is used to divide the processed first optical signal into optical signals of multiple links (lanes) and send them to the first optoelectronic conversion unit 203. The first optoelectronic conversion unit 203 is used to convert the optical signals of the multiple links (lanes) into a first electrical signal and output the first electrical signal to the data decoding unit 204. The data decoding unit 204 is used to decode the first electrical signal. Optionally, the first electrical signal is decoded in an 8b / 10b manner to obtain the high-speed serial bus signal.

[0070] Optionally, the first arrayed waveguide grating 202 divides the processed first optical signal into optical signals of multiple wavelengths, and the number of wavelengths of the optical signals corresponds to the number of links (lanes). For example, the first arrayed waveguide grating 202 divides the processed first optical signal into optical signals of 16 wavelengths, corresponding to 16 links (lanes) of the high-speed serial bus trace.

[0071] The data encoding unit 205 is used to receive the electrical signal from the hard disk 104, encode the high-speed electrical signal. Optionally, the first electrical signal is encoded in an 8b / 10b manner to obtain a second electrical signal, and the second electrical signal is sent to the second optoelectronic conversion unit 206. The second optoelectronic conversion unit 206 is used to convert the second electrical signal into optical signals of multiple links (lanes), and synthesize the optical signals of the multiple links (lanes) into a second optical signal through the second arrayed waveguide grating 207 and output the second optical signal.

[0072] Optionally, the second optoelectronic conversion unit 206 converts the second electrical signal into optical signals of multiple links (lanes), and the number of links (lanes) of the optical signals corresponds to the wavelength data of the optical signals. For example, the second optoelectronic conversion unit 206 converts the second electrical signal into optical signals of 16 links (lanes), corresponding to the high-speed serial bus signal of 16 wavelengths.

[0073] The photoelectric detection unit 208 is used to detect the first optical signal or the second optical signal and output a photoelectric detection signal. Thus, the dynamic management module 105 determines the access status of the high-speed serial bus signal based on the photoelectric detection signal output by the photoelectric detection unit 208, dynamically manages the power consumption of the hard disk 104 through the access status of the high-speed serial bus signal, reduces the energy consumption of the storage resource pool, and is beneficial to the energy-saving control of the storage resource pool.

Multiple hard disks 104 are inserted on the backplane 103, thereby realizing access to the corresponding storage resources.

[0123] In an embodiment of the present invention, by receiving a first optical signal from a high-speed serial bus switch board, converting the first optical signal into a high-speed serial bus signal, and accessing corresponding storage resources, the problem of extremely long high-speed serial bus traces between the CPU and the storage resource pool is solved, and the quality of signal transmission is improved.

[0124] In some embodiments, the method further includes:

[0125] Converting an electrical signal from a hard disk in the storage resource pool structure into a second optical signal, and transmitting the second optical signal to the high-speed serial bus switch board to implement the upload of hard disk status data or data stored on the hard disk.

[0126] Optionally, the storage resource pool structure transmits an electrical signal from the hard disk 104 through the backplane 103 and the connection module 102 to the optoelectronic conversion module 101 to be converted into a second optical signal, and then transmits the second optical signal to the high-speed serial bus switch board to implement the upload of hard disk status data or data stored on the hard disk.

[0127] In an embodiment of the present invention, by converting an electrical signal from a hard disk in the storage resource pool structure into a second optical signal and transmitting the second optical signal to the high-speed serial bus switch board to implement the upload of hard disk status data or data stored on the hard disk, the problem of extremely long high-speed serial bus traces between the CPU and the storage resource pool is solved, and the quality of signal transmission is improved.

[0128] In some embodiments, the method further includes: detecting the first optical signal or the second optical signal to obtain an optoelectronic detection signal, determining the access status of the high-speed serial bus signal based on the optoelectronic detection signal, and dynamically managing the power consumption of the hard disk in the storage resource pool structure based on the access status of the high-speed serial bus signal.

[0129] Optionally, the storage resource pool structure detects the first optical signal or the second optical signal to obtain an optoelectronic detection signal, transmits the optoelectronic detection signal to the dynamic management module 105. The dynamic management module 105 determines the access status of the high-speed serial bus signal based on the optoelectronic detection signal output by the optoelectronic conversion module 101, analyzes the access status, and controls the opening or closing of the power state of the hard disk 104 by outputting high and low levels, so as to dynamically manage the power consumption of the hard disk 104, reduce the energy consumption of the storage resource pool, and facilitate the energy-saving control of the storage resource pool.

[0130] For example, when there is no optical signal for a long time, it is determined that the host's access to the hard disk 104 is in the standby state. At this time, the motherboard management control module 1052 turns off the 12V and 5V voltages of the corresponding hard disk according to the address signal mapping relationship stored in the motherboard management controller (BMC) 10521. When an optical signal is detected, the motherboard management control module 1052 turns on the 12V and 5V voltages of the corresponding hard disk 104 according to the address signal mapping relationship stored in the motherboard management controller (BMC) 10521.

[0131] In the embodiment of the present invention, by detecting the first optical signal or the second optical signal, an optoelectronic detection signal is obtained, and based on the optoelectronic detection signal, the access state of the high-speed serial bus signal is determined. Based on the access state of the high-speed serial bus signal, the power consumption of the hard disk in the storage resource pool structure is dynamically managed, reducing the energy consumption of the storage resource pool, which is beneficial to the energy-saving control of the storage resource pool.
