Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] like figure 2 As shown, it is a schematic diagram of the internal structure of a multi-function hard disk provided in the embodiment of the present application. The multi-function hard disk 20 includes: a first port 21, an internal controller 22 and at least one second port 23, wherein:

[0043] The first port 21 is used to connect with the hard disk controller 11 and receive data sent by the hard disk controller 11 .

[0044] Specifically, the first ...

Abstract

The embodiment of the invention provides a multifunctional hard disk which comprises a first port and at least one second port. The second port is connected with a hard disk. An internal controller can determine a hard disk level mode of the multifunctional hard disk and store data to the hard disk connected with the corresponding second port according to the storage data information corresponding to the hard disk level mode. The hard disk is added in the mode that the second port of the multifunctional hard disk is connected with the hard disk, the mode that the hard disk is added by extending the ports of the hard disk controller is not needed, accordingly the cost is reduced, and the problem that the hard disk controller which cannot be connected with an expansion card cannot increase ports and accordingly more hard disks cannot be added is also solved.

Description

technical field [0001] The embodiment of the present application relates to the technical field of data storage, and more specifically relates to a multi-function hard disk. Background technique [0002] At present, HDD (data storage area, hard disk drive) is referred to as hard disk for short, and requires a hard disk controller such as a RAID (Redundant Array of Independent Disks, disk array) card for control. [0003] Each port in the hard disk controller can be connected to a hard disk, and the total number of ports in the hard disk controller is the maximum number of hard disks that can be connected to it. like figure 1 As shown, it is a schematic diagram of the connection between the hard disk controller and multiple hard disks in the prior art, from figure 1 It can be seen that the hard disk controller 11 has 8 ports: port0-port7; it can be connected to 8 hard disks at most, for example, port0 is connected to HDD (Hard Disk Drive, ie hard disk drive) 0, and port1 is...
