[0023] In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present application and to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.
[0024] See also Figure 2 , Figure 2 A schematic diagram of the structure of a storage frame provided in an embodiment of the present application. Figure 2 As shown, the storage frame 200 integrates a backplane 201, multiple storage modules 202, and multiple switching modules 203; wherein the storage module 202 is configured to be connected to a management network interface of a management network and a storage network interface for connecting to a storage network; the management network interface of each storage module 202 is connected to each switching module 203 via a PCB trace on the backplane 201, and the storage network interface of each storage module 202 is connected to each switching module 203 via a PCB trace on the backplane 201; the storage module 202 is also configured with a BMC and at least one network card;
[0025] In this embodiment, the storage module can be considered to refer to a module for data storage. As an embodiment, the storage module can be, for example, a module formed by integrating a central processing unit (CPU), a BMC, at least one network card, and multiple memory sticks on a PCB board. Here, the physical position layout of each component on the PCB board corresponding to the storage module is not specifically limited, and can be flexibly set based on actual needs. Among them, as an embodiment, the network card supports hot-swappable operation, and the network card can be, for example, an Open Compute Project (OCP) network card, etc., which is not specifically limited in this embodiment.
[0026] As an embodiment, the storage network interface configured by the above storage module for connecting to the storage network may be, for example, a Gigabit Ethernet (GE) network + serial port, or a GE-Universal Asynchronous Receiver / Transmitter (UART) interface, etc. in a specific implementation; the management network interface configured by the above storage module for connecting to the management network may be, for example, a high-speed interface provided by an Ethernet chip supporting the Remote Direct Memory Access (RDMA) protocol, etc. in a specific implementation; this embodiment does not specifically limit the specific implementation of the storage network interface and the management network interface.
[0027] In this embodiment, the switching module can be considered to be a module that supports the functions of both the storage network switch and the management network switch. As an embodiment, the switching module can be, for example, a module that is composed of components such as a processing chip for realizing the functions of the storage network switch and a processing chip for realizing the functions of the management network switch integrated on a PCB board.
[0028] In this embodiment, the backplane may refer to a component that supports PCB routing for connection between modules in the storage chassis.
[0029] In this embodiment, as an embodiment, the physical position layout of the backplane, each storage module and each switching module in the storage frame is not specifically limited. For example, the backplane can be deployed in the middle area of the storage frame; and each storage module and each switching module are deployed on different panels, such as each storage module can be deployed on the front panel of the storage frame, and each switching module can be deployed on the rear panel of the storage frame, or each storage module can be deployed on the rear panel of the storage frame, and each switching module can be deployed on the front panel of the storage frame; or each storage module and each switching module can be deployed on the same panel (such as the front panel or the rear panel).
[0030] In this embodiment, as an example, combined with Figure 3 As shown, first, the storage module receives the business data forwarded by the business network through the local network card; then, the storage module forwards the business data to the switching module connected to the local storage network interface through the PCB wiring through the local storage network interface; then, the switching module can forward the business data to other storage modules connected through the PCB wiring to realize the transmission of business data between various storage nodes, thereby ensuring that the data is evenly stored on the disk and improving storage performance. Here, the local network card and the local storage network interface refer to the network card and storage network interface configured by the storage module.
[0031] In this embodiment, as an embodiment, for the business data received by the storage module through the local network card, the business data can be processed by the CPU configured by the storage module, and then the processed business data is forwarded to the local storage network interface of the storage module through the CPU's upstream high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIe) interface, so that the local storage network interface of the storage module forwards the processed business data to other storage modules connected through PCB routing. Alternatively, for the business data received by the storage module through the local network card, the received business data can also be directly forwarded to other storage modules connected through PCB routing through the local storage network interface of the storage module.
[0032] As an example, combining Figure 3 As shown, the switch module can access the BMC in each storage module through the PCB traces between the switch module and the storage module to obtain management data for network management. Here, the management data may be, for example, the operating temperature, operating voltage, power consumption, CPU usage of the storage module, and traffic monitoring of each network port, etc., which is not specifically limited in this embodiment.
[0033] So far, completed Figure 2 The structure shown.
[0034] pass Figure 2 It can be seen from the structure shown that the storage frame provided by the embodiment of the present application integrates a backplane, multiple storage modules and multiple switching modules, wherein the management network interface of each storage module is connected to each switching module through the PCB trace on the backplane, and the storage network interface of each storage module is connected to each switching module through the PCB trace on the backplane; thus, the communication connection between the modules in the storage frame is realized by PCB trace, which can avoid the increase of wiring cost and time cost caused by the use of physical connection lines for communication connection, and reduce the difficulty of equipment deployment and maintenance. Based on this, the business data received by the storage module through the local network card in this embodiment can be forwarded to the switching module connected through the PCB trace through the local storage network interface, and the switching module can access the BMC in the storage module through the PCB trace between each storage module to obtain management data, so that the data transmission between the modules in the storage frame is realized through PCB trace, which can effectively avoid problems such as communication delay caused by physical connection lines, and improve data transmission performance.
[0035] Furthermore, in the embodiment of the present application, a switching module is used as the function of a storage network switch and a management network switch, and there is no need to deploy independent storage network switching modules and management network switching modules. This not only simplifies the architecture of the storage frame and saves space occupied by the storage frame, but also effectively reduces the time and economic cost of module deployment.
[0036] In order to ensure the normal operation of the storage frame when a storage module or a switching module of the storage frame is pulled out for maintenance, this embodiment performs redundant settings on each storage module of the storage frame and performs master-slave configuration on each switching module. The following describes how to perform redundant settings on each storage module of the storage frame and perform master-slave configuration on each switching module:
[0037] As an embodiment, at least one storage module in the storage frame supports hot-swap operation. Here, hot-swap means that hardware can be inserted or removed during system operation without interrupting the normal operation of the system. Based on this, one of the storage modules in the storage frame is configured as a redundant module, and the other storage modules in each storage module except the redundant module share the same redundant module; when any other storage module is removed, the services of the other removed storage modules are taken over by the redundant module, thereby ensuring the normal operation of the entire storage frame.
[0038] As an embodiment, at least one switching module in the storage frame supports hot-swap operation. Based on this, one of the switching modules in the storage frame is configured as a master switching module, and the other switching modules in the switching modules except the master switching module are configured as slave switching modules; when the master switching module is pulled out, the function of the master switching module is assumed by one of the slave switching modules, thereby ensuring the normal operation of the entire storage frame.
[0039] Combine the following Figure 3 The configuration of the above storage chassis is further described.
[0040] First, the switch module of the above storage chassis is further described:
[0041] As an embodiment, the switch module is configured with at least two management network interfaces (ie, Figure 3 The interface corresponds to the double-arrow dashed line in the figure) and at least one storage network interface for connecting to the storage network (that is, the interface corresponding to the double-arrow solid line in the figure).
[0042] In this embodiment, the management network interface of the switching module can be, for example, a manageable Internet Protocol (Internet Protocol) IP address / debugging serial port, etc. when it is specifically implemented; the storage network interface of the switching module can be, for example, an optical port (i.e., a fiber optic interface), etc. when it is specifically implemented; this embodiment does not make specific limitations.
[0043] In this embodiment, as an embodiment, the multiple management network interfaces of the above-mentioned switching module are provided by different switching chips (Switch), so that each management network interface can be guaranteed to be independent of each other and not affect each other. Based on this, one of the management network interfaces of the switching module is configured as the main management network interface, and the other management network interfaces of the switching module except the main management network interface are configured as backup management network interfaces; in this way, when the main management network interface in the switching module fails, the function of the main management network interface can be assumed by one of the backup management network interfaces of the switching module, thereby ensuring the reliability of the management network.
[0044] Based on the above description, it can be seen that the storage frame provided in this embodiment provides an external management network interface through a switching module for network management of each module in the storage frame. In this way, there is no need for each storage module to provide an external management network interface through a separate network port, serial port or other actual physical port for management of the storage module network. For example, if there are n storage modules, this embodiment can save n-2 actual management network interfaces, effectively reduce the occupation of physical space by actual physical ports, and save costs.
[0045] And, if Figure 3 As shown, in the storage frame provided by this embodiment, each switching module is also connected through the PCB traces on the backplane, and each storage module is connected to each switching module through the PCB traces on the backplane, that is, the switching module is aggregated by multiple storage modules uplinked to the switching modules; based on this, when one of the switching modules fails (such as hanging, etc.), the BMC of the storage module can be accessed through the standby switching module (that is, other switching modules connected to the storage module through PCB traces) to obtain management data for network management, thereby improving the reliability of the management network.
[0046] In this embodiment, if Figure 3 As shown, the service data gathered by each storage module to the switching module can be transmitted to other external devices through the storage network interface of the switching module. Here, the number of storage network interfaces of the switching module can be flexibly set based on actual needs, and this embodiment does not specifically limit it.
[0047] Exemplarily, the switching module can support a storage network configuration of n:k, where n represents the number of storage modules, k represents the number of storage network interfaces of the switching module, and the value of k can be 1, 2, 4, ..., k; when n=4, it means that the storage frame is integrated with 4 storage modules. Assuming that the storage network interface of the switching module is an optical port, and the uplink high-speed link of each storage module is 100G (that is, the maximum business data transmission volume from each storage module to the switching module is 100G), then the business data transmission volume of the 4 storage modules aggregated to one switching module is The maximum output is 400G; based on this, the switching module can be configured differently according to actual business needs. For example, when k=1, one storage network interface can be used to access one 400G optical module for storage network networking; when k=2, two storage network interfaces can be used to access one 200G optical module each for storage network networking; when k=4, four storage network interfaces can be used to access one 100G optical module each for storage network networking; and so on, when k=k, k storage network interfaces can be used to access k 400 / k G optical modules each for storage network networking.
[0048] The following describes the power supply of the storage chassis:
[0049] As an embodiment, the storage frame further integrates at least two power modules; each power module is connected to each switching module and each storage module through a PCB trace on the backplane to supply power to each switching module and each storage module. Here, the power module can be, for example, a power supply unit (PSU) when implemented specifically, and this embodiment does not specifically limit this.
[0050] In this embodiment, a power supply module is integrated in the storage frame, and each switching module and each storage module are connected through PCB wiring to power each module. In this way, there is no need to configure a power supply module for powering each module in the storage frame separately, thereby saving the number of power supply modules and the space of the storage frame.
[0051] Furthermore, in this embodiment, the influence of power module failure on the storage frame is further considered. Therefore, in order to ensure the reliable operation of the storage frame, the power modules are configured to be in a master-slave relationship with each other. In this way, when any power module among the power modules fails, the other power modules among the power modules except the failed power module will supply power to the switching modules and the storage modules, thereby avoiding problems such as the storage frame freezing due to the power module failure.
[0052] In this embodiment, visual monitoring and management of each module in the storage chassis is also supported, so that operation and maintenance personnel can maintain and manage the storage chassis. The following describes how to visually monitor and manage each module in the storage chassis:
[0053] As an embodiment, each switching module is configured with a target software program, and the target software program supports providing a visual page to the outside; the local management network interface of each switching module supports connecting to an external designated device for displaying a visual page. Here, the external designated device can be, for example, a computer device of a client, etc., which is not specifically limited in this embodiment.
[0054] In this embodiment, the switching modules are cascaded through PCB routing on the backplane; in actual application, the target software program in the main switching module is enabled to provide a visualization page for the external specified device, and the visualization page is used to monitor and manage the storage modules, switching modules, and power modules in the storage frame. Here, there is no specific limitation on the content of the visualization page, for example, it may include the operating status, business flow, bandwidth, CPU usage, load, and memory usage of each module, and may also include configuration options for each module for operation and maintenance personnel to perform flexible configuration management based on actual business needs.
[0055] In this embodiment, the storage frame can also support dynamic adjustment of the whole machine power consumption and fan speed, so that the whole machine power consumption and fan speed are both within a reasonable range to ensure the normal and reliable operation of the storage frame. The following describes how to dynamically adjust the whole machine power consumption and fan speed:
[0056] As an embodiment, the target software program in the main switching module is also used to determine whether the power consumption of the storage frame needs to be adjusted based on the power consumption of the storage frame, and adjust the power consumption of the storage frame based on the working conditions of each storage module after determining that the power consumption of the storage frame needs to be adjusted.
[0057] In this embodiment, there are many specific implementation methods for determining whether the power consumption of the storage frame needs to be adjusted based on the power consumption of the storage frame. For example, as an embodiment, first, the power consumption of the storage frame is obtained; then, the total business flow of each storage module in a specified time period is obtained; thereafter, the reference power consumption corresponding to the above total business flow is determined based on the configured power consumption-business flow mapping table; if it is found that the power consumption of the storage frame is greater than the reference power consumption, it means that there is power consumption waste in the storage frame, and at this time, the power consumption of the storage frame needs to be adjusted to a reasonable power consumption range, that is, it is determined that the power consumption of the storage frame needs to be adjusted; if it is found that the power consumption of the storage frame is less than or equal to the reference power consumption, it means that there is no power consumption waste in the storage frame, and at this time, it is determined that the power consumption of the storage frame does not need to be adjusted.
[0058] In this embodiment, the power consumption of the storage frame refers to the sum of the power consumption of each module in the storage frame (such as storage module, switching module, optical module connected to the switching module, etc., which is not specifically limited in this embodiment). The power consumption data of each module is usually calculated regularly and stored in the designated storage space of each module. Based on this, the power consumption of the storage frame can be obtained in the specific implementation, for example: the power consumption of each module is obtained from the designated storage space corresponding to each module, and the sum of the power consumption of each module is determined as the power consumption of the storage frame.
[0059] In this embodiment, the above-mentioned specified time period refers to a time period with the time when the total service flow is obtained as the end time. The above-mentioned obtaining of the total service flow of each storage module in the specified time period is similar to the above-mentioned obtaining of the power consumption of the storage frame, for example, obtaining the service flow of each storage module in the specified time period from the specified storage space of each storage module, so as to determine the sum of the service flow of each storage module in the specified time period as the total service flow of each storage module in the specified time period. Here, the service flow refers to the amount of service data received by the storage module in the specified time period.
[0060] In the present embodiment, after determining that the power consumption of the storage frame needs to be adjusted, the power consumption of the storage frame is adjusted according to the working conditions of each storage module. There are many ways to implement it in specific implementation. For example, as an embodiment, the state of an idle storage module that is not currently processing business can be switched to a standby state, and / or the state of at least one idle optical module connected to the switching module can be controlled to switch to a standby state, so as to adjust the power consumption of the storage frame to within the power consumption range associated with the reference power consumption. Here, the idle optical module can be understood as an optical module that is not used for data transmission. The power consumption range associated with the reference power consumption refers to, for example, a power consumption range with the reference power consumption as the middle value and the difference between the upper and lower limits of the range as a set value, which is not specifically limited in the present embodiment.
[0061] The above describes how to dynamically adjust the power consumption of the entire machine. The following describes how to dynamically adjust the fan speed of the storage chassis:
[0062] As an embodiment, the storage module is configured with at least one fan assembly; the target software program in the main switching module is also used to adjust the rotation speed of the fan assembly of each storage module according to the power consumption of the storage frame so that the storage frame operates within a specified temperature range.
[0063] In the present embodiment, the rotation speed of the fan assembly of each storage module is adjusted according to the power consumption of the storage frame so that the storage frame operates within a specified temperature range. In a specific implementation, for example, the following steps may be performed: first, the power consumption of the storage frame is obtained; then, based on the configured power consumption-fan speed correspondence relationship, a target fan speed corresponding to the power consumption of the storage frame is determined; thereafter, the fan speed of each storage module is controlled to be the target fan speed so that the storage frame operates within a specified temperature range.
[0064] It should be noted that the power consumption and fan speed of the storage frame of this embodiment can not only be adjusted automatically, but also the power consumption and fan speed of the storage frame can be monitored through the above-mentioned visualization page, and each module in the storage frame can be manually controlled through the configuration options on the visualization page, so that the storage frame operates within a reasonable power consumption range and the storage frame operates within a reasonable temperature range.
[0065] At this point, the structural description of the storage frame provided in the embodiment of the present application is completed. The storage system provided in the embodiment of the present application is described below:
