Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The storage device includes an interface, a controller, and a storage medium.
The Interface is a physical link for connecting the storage device and the host, and the standard formats include USB (Universal Serial Bus), SATA (Serial Advanced technology attachment), SCSI (Small Computer System Interface), FC (Fiber Channel), iSCSI (Internet Small Computer System Interface), and the like.
The controller is used for realizing the management of the storage medium and is responsible for data communication between the storage medium and the host. The controller is typically in the form of a circuit board, and some complex controllers also run a software on the circuit board. The higher-end controller itself is actually a small computer system, including a separate CPU and memory, running a particular operating system.
The storage medium is used for storing data content. Common types of storage media are magnetic disks, magnetic tapes, optical disks, semiconductor disks (Flash), etc.
The storage device described in the embodiment of the invention can be used in cooperation with a server and is used for storing data in the server; for example, the Storage device described in the embodiment of the present invention may be a NAS (network attached Storage) Storage device, and may also be a Storage device connected to a host through a fiber interface.
Referring to fig. 2, a flowchart illustrating a first step of a first embodiment of a method for controlling a storage device according to the present invention is shown, where the storage device includes: the storage device comprises at least two interfaces, at least two controllers with different architectures and a storage medium, wherein a one-to-one connection relationship exists between the at least two interfaces and the controllers, namely each interface is connected with one controller corresponding to the interface, for example, the storage device comprises an interface 1, an interface 2, a controller 1 and a controller 2, wherein the interface 1 is connected with the controller 1, and the interface 2 is connected with the controller 2; the at least two controllers with different architectures are connected to the storage medium, and the method may specifically include the following steps:
in the embodiment of the invention, the storage device at least comprises two interfaces which can be connected with the host, and at least two controllers with different architectures, wherein each controller is connected with the host through a corresponding interface.
The controller of the embodiment of the invention can be an independent computer system, and comprises a CPU, a memory and an operating system.
The System architecture (System architecture) of a controller refers to the combination of types of CPUs, memories, and operating systems employed by the controller. Different architectures may be chosen to achieve the same functionality but with different computational power and power consumption.
Referring to table 1, a list of information for a controller of a different architecture is shown.
The same functionality can be achieved using a controller of any of the architectures in the above table. The storage device may be configured such that a controller of any one of the plurality of controllers is set to an operating state, the controller set to the operating state is set to an operating controller, and the other controllers are set to a standby state, that is, the other controllers are set to standby controllers.
The computing power of the controller may include four aspects of data: the number of processes (ProcessNumbers), the Memory occupation (Memory), the file access rate (FileRate) and the network rate (NetworkRate). The four data are independent of each other. Generally, the greater the maximum computing power, the greater the values of these four data, and the greater the corresponding power consumption.
Referring to table 2, a list of information of the computing power is shown.
The host accesses the storage medium through the work controller while the work controller is running. The computing capacity load information indicates the computing capacity used by the job controller at runtime.
Specifically, the computing capacity load information of the work controller can be obtained in a real-time monitoring manner.
specifically, it may be determined whether the computing power of the work controller is excessive by using preset maximum computing power information of the work controller and current computing power load information of the work controller.
If each item of data in the computing capacity load information is smaller than each item of data in the maximum computing capacity information, the computing capacity is excessive.
For example, the number of processes, the memory occupation amount, the file access rate, and the network rate in the computing power load information may be sequentially compared with the number of processes, the memory occupation amount, the file access rate, and the network rate in the maximum computing power information; if all the four items of data in the computing capacity load information are smaller than the four items of data in the maximum computing capacity information, the computing capacity is excessive.
Of course, the above-mentioned manner for determining whether the computing power of the controller is excessive is only an example, and a person skilled in the art may also use other manners to determine whether the computing power of the controller is excessive, and the embodiment of the present invention is not limited herein.
103, if the computing capability of the controller in the working state is excessive, determining a first target controller from the controllers in the waiting state, wherein the first target controller is the controller in the waiting state with the highest computing capability information meeting the computing capability load information and the lowest power consumption;
when the calculation capability of the current working controller is excessive, the maximum calculation capability information can be selected to meet the calculation capability load information, and the waiting controller with the lowest power consumption is used as the first target controller. And the power consumption of the first target controller is less than that of the controller in the working state.
And 104, switching the controller in the working state from the working state to a waiting state, and switching the first target controller from the waiting state to the working state.
And switching the original working controller from the working state to the waiting state, and simultaneously switching the first target controller from the waiting state to the working state.
In the embodiment of the present invention, whether the work controller is capable of calculating the excess capacity may be determined according to the current information of the calculation capability load of the work controller. When the computing capacity is excessive, the waiting controller with the maximum computing capacity information meeting the computing capacity load information and the lowest power consumption is switched to the working state, so that the average power consumption of the storage device is the lowest power consumption value under the condition of meeting the resource use condition.
Referring to fig. 3, a flowchart illustrating steps of a second embodiment of a method for controlling a storage device according to the present invention is shown, where the storage device includes: the method specifically includes the following steps:
in this embodiment of the present invention, the step 202 may include:
and judging whether the controller in the working state is over-calculation capacity within continuous preset time period or not by adopting preset maximum calculation capacity information of the controller in the working state and calculation capacity load information of the controller in the working state.
To prevent the controller from switching too frequently, a certain guard period is set. If the work controller has a surplus of continuous computing power during the guard period, a switchover is performed. If the excess capacity is calculated only occasionally, no switching is performed.
In practice, the switching frequency is typically no higher than one minute. That is, if one controller is continuously operating for more than one minute and continues to be performance-redundant, a switchover is performed.
in an embodiment of the present invention, the step 203 may include the following sub-steps:
a substep S11, obtaining preset maximum computing power information and power consumption of each controller in the waiting state;
specifically, in the storage device, there may be an independent storage area (generally, a hard disk) for uniformly storing the maximum computing power information and the power consumption of each controller.
And a substep S12 of determining the controller in the waiting state with the minimum power consumption, which satisfies the maximum calculation capability load information, as the first target controller.
The standby controllers whose maximum computation power information satisfies the computation power load information may be selected first, and then the standby controller having the smallest power consumption among the selected standby controllers may be determined as the first target controller.
in practice, the storage devices may include both centralized storage devices and distributed storage devices. Different types of storage devices are switched differently for the controller.
In an example of the embodiment of the present invention, the storage device is a centralized storage device, and the storage device may further include: a monitoring module in communication with the at least two different architecture controllers;
the step 204 may comprise the following sub-steps:
a substep S21, determining whether the first target controller can normally operate through the monitoring module;
in the centralized storage facility, a dedicated monitoring module is provided, which is independent of all controllers. The monitoring module can communicate with the controller, and the monitoring module sends a state inquiry command to the controller at regular time and returns a response message if the controller works normally (the controller can work normally). If the returned message is not normal or no message is returned within a specified time, the controller may be considered to have failed.
And a substep S22, if the first target controller can operate normally, controlling the controller in the working state to switch from the working state to the waiting state through the monitoring module, and controlling the first target controller to switch from the waiting state to the working state.
If the first target controller can normally operate, the monitoring module is responsible for switching between the controllers, namely the monitoring module controls the original working controller to be switched from the working state to the waiting state, and the monitoring module controls the first target controller to be switched from the waiting state to the working state.
In another example of the embodiment of the present invention, the storage device is a distributed storage device, and the step 204 may include the following sub-steps:
a substep S31 of communicating with each other through the at least two controllers;
a substep S32 of determining whether the first target controller can normally operate according to the communication result;
and a substep S33, if the first target controller can operate normally, controlling the controller in the working state to switch from the working state to the waiting state through the first target controller, and switching the first target controller from the waiting state to the working state.
The distributed storage device is not provided with a special monitoring module, all controllers are in message communication, and messages and response messages are sent according to state inquiry commands between every two controllers. And then, determining whether the state of each controller is normal or failed through a group arbitration algorithm among the controllers.
If the first target controller can normally work, the first target controller is responsible for switching. The first target controller controls the original working controller to be switched from the working state to the waiting state, and the first target controller controls the first target controller to be switched from the waiting state to the working state.
In the embodiment of the invention, the controller in the working state is used as the working controller, and the controller in the waiting state is used as the waiting controller.
specifically, the preset maximum computing power information of the work controller may be compared with the current computing power load information of the work controller to determine whether the computing power of the work controller is insufficient.
If at least one item of data in the computing capacity load information is equal to the data of the corresponding item in the maximum computing capacity information, the computing capacity is insufficient.
For example, the number of processes, the memory occupation amount, the file access rate, and the network rate in the computing power load information may be sequentially compared with the number of processes, the memory occupation amount, the file access rate, and the network rate in the maximum computing power information; if a certain item of data in the computing capacity load information is equal to the data of the corresponding item in the maximum computing capacity information, the computing capacity is insufficient.
Of course, the above-mentioned manner for determining whether the computing power of the controller is insufficient is only an example, and a person skilled in the art may also use other manners to determine whether the computing power of the controller is insufficient, and the embodiment of the present invention is not limited herein.
If the computing power of the working controller is insufficient, the controller with the maximum computing power to meet the computing power load information and the lowest power consumption needs to be switched to.
In this embodiment of the present invention, the step 205 may include:
and judging whether the computing power of the controller in the working state is insufficient in a continuous preset time period by adopting preset maximum computing power information of the controller in the working state and computing power load information of the controller in the working state.
To prevent the controller from switching too frequently, a certain guard period is set. If the duty controller has insufficient continuous computing power during the guard period, a switchover is performed. If the computing power is insufficient only occasionally, no handover occurs.
in an embodiment of the present invention, the step 206 may include the following sub-steps:
a substep S41, obtaining preset maximum computing power information and power consumption of each controller in the waiting state;
and a substep S42 of determining the controller in the waiting state with the minimum power consumption, which satisfies the maximum calculation capability load information, as the second target controller.
The standby controller whose maximum computing power information satisfies the computing power load information may be selected first, and then the standby controller having the smallest power consumption among the selected standby controllers may be determined as the second target controller.
And step 207, switching the controller in the working state from the working state to a waiting state, and switching the second target controller from the waiting state to the working state.
In an example of the embodiment of the present invention, the storage device is a centralized storage device, and the step 207 may include the following sub-steps:
a substep S51, determining whether the second target controller can normally operate through the monitoring module;
and a substep S52, if the second target controller can operate normally, controlling the second target controller to switch from the waiting state to the working state through the monitoring module, and controlling the controller in the working state to switch from the working state to the waiting state.
If the second target controller can normally operate, the monitoring module is responsible for switching, the monitoring module controls the second target controller to be switched from the waiting state to the working state, and the monitoring module controls the original working controller to be switched from the working state to the waiting state.
In another example of the embodiment of the present invention, the storage device is a distributed storage device, and the step 207 may include the following sub-steps:
a substep 61 of communicating with each other through said at least two controllers;
a substep 62 of judging whether the second target controller can normally operate or not according to the communication result;
and a substep 63, if the second target controller can operate normally, controlling the controller in the working state to switch from the working state to the waiting state through the second target controller, and switching the second target controller from the waiting state to the working state.
If the second target controller can normally work, the second target controller is responsible for switching. The second target controller controls the original working controller to be switched from the working state to the waiting state, and the second target controller controls the second target controller to be switched from the waiting state to the working state.
In the embodiment of the present invention, whether the work controller is capable of calculating the excess capacity may be determined according to the current information of the calculation capability load of the work controller. When the computing capacity is excessive, the waiting controller with the maximum computing capacity information meeting the computing capacity load information and the lowest power consumption is switched to the working state, so that the average power consumption of the storage device is the lowest power consumption value under the condition of meeting the resource use condition.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
