Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
In the prior art, under the condition that the hard disk is not fully installed, the problem of bandwidth resource waste occurs, so that a method strategy for improving the traditional bandwidth allocation is needed. In order to solve the technical problems, the method acquires the total bandwidth by determining the target hard disk connected with the backboard hard disk slot position, and finally distributes the total bandwidth to the target hard disk, so that the bandwidth of the target hard disk is dynamically adjusted according to the total bandwidth and the target hard disk.
Referring to fig. 1, a flowchart illustrating steps of a bandwidth adjustment method according to an embodiment of the present invention is shown, where the method is applied to a server, where the server has a high-speed serial computer expansion bus standard PCIe device, and the PCIe device includes a backplane hard disk slot, where the backplane hard disk slot is connected to at least one hard disk, and the method specifically may include the following steps:
and step 101, detecting the connection state of the hard disk, and determining at least one target hard disk currently connected with the backboard hard disk slot when the connection state changes.
In the embodiment of the invention, PCIe equipment can be installed in the server, the PCIe equipment can comprise a plurality of backboard hard disk slots, and the hard disk can be connected with the backboard hard disk slots so as to be connected with the server. The server may detect the connection state of the hard disk in real time, and when the connection state of the hard disk changes, for example: the number of hard disks connected with the backboard hard disk slot is changed, and the positions of the hard disks connected with the backboard hard disk slot are changed. The server may determine at least one target hard disk currently connected to the backplane hard disk slot, wherein the at least one target hard disk is all hard disks connected to the backplane hard disk slot.
Step 102, obtaining the total bandwidth of the PCIe device.
In the embodiment of the present invention, after the target hard disk is determined, the total bandwidth of the PCIe device may be obtained, and in practical application, the total bandwidth of the PCIe device is generally X16, or may be other bandwidth numbers. For a better description of the embodiments of the present application, the total bandwidth of PCIe devices in subsequent embodiments is exemplified by X16.
And step 103, respectively distributing the total bandwidth of the PCIe device to the at least one target hard disk.
In the embodiment of the invention, after obtaining the total bandwidth of the PCIe device, the server may enter an IIO (Integrated I/o module) configuration menu through a BIOS (Basic Input Output System ) to automatically divide the total bandwidth of the PCIe device, then allocate the divided bandwidths to the backboard hard disk slots respectively, and then adjust the bandwidth of the target hard disk connected to the backboard hard disk slots, so that the bandwidth of the target hard disk is consistent with the bandwidth of the corresponding backboard hard disk slot.
In an embodiment, after determining the target hard disk currently connected to the backboard hard disk slot, the number of hard disk of at least one target hard disk, the slot number of the backboard hard disk, and the slot number of the target backboard hard disk slot may be obtained, where the target backboard hard disk slot is the backboard hard disk slot connected to the at least one target hard disk. Dividing the total bandwidth of the PCIe device to obtain at least one sub-bandwidth; the number of the sub-bandwidths is the same as the number of the hard disks; respectively distributing sub-bandwidths to the target backboard hard disc slots according to the number of slots of the target backboard hard disc slots; and adjusting the bandwidth of at least one target hard disk corresponding to the target backboard hard disk slot according to the sub-bandwidth allocated by the target backboard hard disk slot, so that the bandwidth of at least one target hard disk is consistent with the sub-bandwidth of the corresponding target backboard hard disk slot. For example: the number of the hard disks of the target hard disk connected with the backboard hard disk slot positions is 5, the total bandwidth of the PCIe equipment is divided into 5 sub-bandwidths, and then the 5 sub-bandwidths are respectively distributed to five target backboard hard disk slot positions according to the slot number of the target backboard slot positions.
In an embodiment, in the present application, the dividing the total bandwidth of the PCIe device to obtain at least one sub-bandwidth may be obtained by: calculating the reference number of the hard disks according to the number of the slots of the hard disk slots of the backboard; the reference number of the hard disks is smaller than the number of the slots; calculating a first reference bandwidth value and a second reference bandwidth value according to the total bandwidth and the slot number of the PCIe device; the first reference bandwidth value is greater than the second reference bandwidth value; dividing the total bandwidth of the PCIe device according to the number of hard disks, the number of slots, the number of hard disk references, the first reference bandwidth value and the second reference bandwidth value to obtain at least one sub-bandwidth. For example: the number of the hard disks is 5, the number of slots of the backboard is 8, the number of the hard disk references is calculated to be 4, the first reference bandwidth value is calculated to be X4, and the second reference bandwidth value is calculated to be X2, so that the total bandwidth of the PCIe device is divided into 5 sub bandwidths according to the number of the hard disks, the number of the slots, the number of the hard disk references, the first reference bandwidth value and the second reference bandwidth value.
In one embodiment, the first and second reference bandwidth values are calculated by: taking the quotient of the total bandwidth of the PCIe device and the slot number as a second reference bandwidth value; and taking the product of the second reference bandwidth value and the preset coefficient as the first reference bandwidth value. For example: the total bandwidth of the PCIe device is X16, the number of slots is 8, the total bandwidth of the PCIe device may be divided by the number of slots to obtain a second reference bandwidth value X2, and then the second reference value is multiplied by a preset coefficient 2 to obtain a first reference bandwidth value X4. In this application, the first reference bandwidth value and the second reference bandwidth value may also be preset parameters, and the manner of obtaining the first reference bandwidth value and the second reference bandwidth value is not specifically limited herein.
In an embodiment, the total bandwidth of the PCIe device is divided according to the number of hard disks, the number of slots, the number of hard disk references, the first reference bandwidth value, and the second reference bandwidth value, to obtain at least one sub-bandwidth, which may be divided by: when the number of hard disks is smaller than or equal to the reference number of hard disks, dividing the total bandwidth of the PCIe device into sub-bandwidths which are the same as the number of hard disks and the bandwidth values of which are the first reference bandwidth values. For example: the total bandwidth of the PCIe device is X16, the number of hard disks is 4, the number of hard disk references is 4, the first reference bandwidth value is X4, when the total bandwidth of the PCIe device is divided, if the number of hard disks is judged to be equal to the number of hard disk references, the total bandwidth of the PCIe device is divided into 4 sub-bandwidths with the bandwidth value of X4.
In another example, the total bandwidth of the PCIe device is divided according to the number of hard disks, the number of slots, the number of hard disk references, the first reference bandwidth value, and the second reference bandwidth value, to obtain at least one sub-bandwidth, which may be divided by: when the number of the hard disks is larger than the reference number of the hard disks and smaller than the number of the slots, calculating a first division number with a bandwidth value being a first reference bandwidth value and a second division number with a bandwidth value being a second reference bandwidth value according to the number of the slots and the number of the hard disks; the total bandwidth of the PCIe device is divided into sub-bandwidths equal to the first division number and each being a first reference bandwidth value, and sub-bandwidths equal to the second division number and each being a second reference bandwidth value.
The first division number may be calculated by the formula a1=m-N, the second division number may be calculated by the formula a2=2n-M, A1 is the first division number, A2 is the second division number, M is the slot number, and N is the hard disk number. In this application, the first division number and the second division number may be calculated by other methods, which are not specifically limited herein.
For example: the total bandwidth of the PCIe device is X16, the number of slots is 8, the number of hard disks is 5, the number of hard disk references is 4, the first reference bandwidth value is X4, the second reference bandwidth value is X2, it can be judged that the number of hard disks is larger than the number of hard disk references, at this time, the first division number is 3, the second division number is 2, and then the total bandwidth of the PCIe device can be divided into 3 sub-bandwidths with the bandwidth value of X4 and 2 sub-bandwidths with the bandwidth value of X2.
In another example, the total bandwidth of the PCIe device is divided according to the number of hard disks, the number of slots, the number of hard disk references, the first reference bandwidth value, and the second reference bandwidth value, to obtain at least one sub-bandwidth, which may be divided by: when the number of hard disks is equal to the number of slots, dividing the total bandwidth of the PCIe device into sub-bandwidths which are the same as the number of hard disks and are both the second reference bandwidth value. For example: the total bandwidth of the PCIe device is X16, the number of slots is 8, the number of hard disks is 8, and the second reference bandwidth value is X2, where it may be determined that the number of hard disks is equal to the number of slots, and at this time, the total bandwidth of the PCIe device may be divided into 8 sub-bandwidths with the bandwidth value of X2.
