All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a storage device supporting a disk controller integration and a disk controller separation according to the present invention, including:
a hollow housing.
The casing is not shown in fig. 1, and may be a casing of a common rectangular parallelepiped or square structure, and of course, in practical applications, the specific shape structure and parameters of the casing may be set and adjusted according to actual needs, so that the casing is suitable for actual needs, and the implementation of the present invention is not affected.
A first bracket 10 disposed at the bottom inside the cabinet.
The various components of the present application are placed in a cabinet with the first tray 10 placed at the lowest level. The specific structure of the first bracket 10 can be set according to actual conditions, for example, the frame profile can be a cuboid or a cube structure, and the shape of the frame interior can be designed according to the device to be placed in the first bracket 10. The device may be a hard disk 40 or a BBU (Battery Backup Unit) Battery 50, and the device may be placed or fixed in the first bracket 10.
The N controllers 20 are arranged on the top of the first bracket 10, the heights of the controllers 20 from the bottom of the machine shell are the same, and N is a positive integer.
The N controllers 20 are all disposed on the top of the first bracket 10, that is, all placed on the top plane of the first bracket 10, and the heights of the controllers 20 from the bottom of the casing are the same, that is, the N controllers 20 are at the same horizontal height.
In consideration of the fact that in the field of storage, more and more complete machines need to be provided with two controllers 20, namely one master controller 20 and one slave controller 20, and the fault handling capability of the storage device can be improved, in the scheme of the application, the value of N may be generally 2. Referring to fig. 2, in the embodiment of fig. 2, there are two controllers 20. Fig. 2 is a top view showing the controller 20 and the first bracket 10 at the bottom of the controller 20 when the disk controllers are separated, and other components in the housing are not shown.
Each controller 20 is provided with a buckle 30. The snap 30 of the present application refers to a card connected to the controller 20 for connecting the BBU battery 50 and the controller 20 in a controller-integrated configuration, which is the case in the embodiment of FIG. 1. It should be noted that, in addition to the buckle 30 for connecting the controller 20 and the BBU battery 50, the buckle 30 may also be provided with other functions, that is, as a board card for implementing an extended function, that is, no matter the architecture is integrated with the disk control or separated from the disk control, the scheme of the present application does not require to detach the buckle 30, that is, when switching between the integrated with the disk control and the separated from the disk control is performed, the connection relationship between the buckle 30 and the controller 20 is not changed.
When the storage device is used as a disk control integrated device, the first bracket 10 is a hard disk bracket for placing the hard disk 40, and the hard disk 40 is connected with the back plate 60, so that the N controllers 20 control the hard disk 40 through the back plate 60; BBU batteries 50 are disposed atop controllers 20 and are connected to each of the N controllers 20 by N clips 30.
A backplane 60 disposed in the housing and connected to each of the N controllers 20.

Hard disk 40 is connected with backplate 60, and N controller 20 also all is connected with backplate 60, therefore every controller 20 all can be through backplate 60 control hard disk 40. That is to say, the solution of the present application does not directly connect the hard disk 40 with the controller 20, but uses the backplane 60 as a medium, so when switching between the architecture of integrated disk control and the architecture of separated disk control, the solution of the present application does not need to modify the structure of the controller 20 due to the position change of the hard disk 40. Meanwhile, when the memory device is a disk-on-board device, the BBU batteries 50 are disposed on top of the controllers 20 and are connected to each of the N controllers 20 via the N clips 30.
When the memory device is a disk-on-board separation device, the first bay 10 is a battery bay for housing BBU batteries 50, and the BBU batteries 50 in the first bay 10 are connected to the controller 20 through the backplane 60.
FIG. 3 illustrates a schematic diagram of a disk separation in an embodiment. In a configuration with separate disk control, the first bracket 10 is a battery bracket, which may also be referred to as a BBU adapter board, the BBU batteries 50 are placed in the battery bracket, the BBU batteries 50 are connected to the backplane 60, and the N controllers 20 are all connected to the backplane 60, so that the connection between the BBU batteries 50 and each of the controllers 20 is realized.
If the disk controller is to be switched to a disk controller, the first cradle 10 is not moved, only the BBU batteries 50 in the first cradle 10 are replaced with the hard disks 40, and the hard disks 40 are connected to the back plate 60, or the battery cradle together with the first cradle 10 is removed, together with the BBU batteries 50 placed inside, and replaced with a hard disk cradle in which the hard disks 40 are placed. In practical applications, a uniform replacement scheme is usually selected in consideration of convenience of switching and possible difference between internal frames of the hard disk tray and the battery tray. That is, when the disk controller is switched to the disk controller integrated body, the first cradle 10 is switched together with the BBU batteries 50. In addition, when switching to a disk controller, BBU batteries 50 are also placed on the top of the controllers 20, and the BBU batteries 50 are connected to the respective controllers 20 by means of the clips 30.
If the integrated controller is to be switched to the controller-separate controller, the BBU batteries 50 placed on top of the controller 20 are removed. And typically also replaces the first carrier 10 with the internal components, i.e., the hard disk carrier and hard disk 40 are removed from the enclosure and a battery carrier, in which the BBU batteries 50 are disposed, is placed at the bottom of the controller 20.
In addition, when switching between the integrated disk control and the separated disk control is performed, the connection between the hard disk 40 and the backplane 60 and the connection between the BBU battery 50 and the backplane 60 can be realized by simply changing the wiring manner, so that the implementation cost is low, and the operation is easy. In addition, in the integrated disk control architecture, the connection between the BBU battery 50 and the buckle 30 is also simple.

In the scheme of the application, because when the disk control is integrated, the hard disk is not directly connected with the controller, so that the structure of the controller is not required to be changed due to the hard disk when the storage device is switched between the disk control integration and the disk control separation. The BBU batteries are not directly connected with the controller, when the disk controller is integrated, the BBU batteries are connected with the controller through the buckling cards, and when the disk controller is separated, the BBU batteries are connected with the controller through the back plate, so that the structure of the controller cannot be changed due to the BBU batteries in the scheme of the application. And no matter the integrated or separation of accuse of dish, first bracket has all been placed in the bottom of controller in this application scheme for the height of controller can not take place to change by a wide margin, need not change the relation of connection of controller and backplate, also can not be because of the structure that the position change of controller needs to change the controller. In conclusion, according to the scheme of the application, when switching between the integrated control and the separated control is carried out, workers do not need to modify the structure of the controller, and development cost caused by designing two controllers is avoided.
In an embodiment of the present invention, a difference between the height of the hard disk tray and the height of the battery tray is less than or equal to a preset threshold.
Considering that, when switching between the integral control and the separate control, the devices placed inside the first bracket 10 are usually replaced together with the first bracket 10 itself, therefore, the difference between the height of the hard disk bracket and the height of the battery bracket may be smaller than or equal to the preset threshold, and the preset threshold is usually set to be smaller, so that the height change of the controller 20 is lower, on one hand, the structure of the controller 20 does not need to be changed due to the change of the position of the controller 20, and on the other hand, poor contact between the controller 20 and the back plate 60 can be avoided. Further, the height of the hard disk tray may be the same as the height of the battery tray, i.e. the preset threshold is 0.
In specific implementation, in combination with the shape parameters of the hard disk 40 and the BBU battery 50 in a normal service, the height of the hard disk bracket may be the same as the height of the battery bracket, and the height may occupy half of the height of the chassis. Further, in practical applications, the height of the case may be set to 4U, where 1U is 4.445cm, and the height of the first bracket 10 is 8.89cm, that is, the height of the hard disk bracket and the height of the battery bracket in this embodiment may both be 8.89 cm.
