Embodiment Construction

[0036] As mentioned in the background section, how to use multiple hard disk devices to realize large-capacity storage has become an urgent problem to be solved.

[0037] In view of this, an embodiment of the present invention provides a hard disk device, the hard disk device includes at least two Ethernet interfaces, wherein one Ethernet interface is used to connect to the Ethernet interface of another hard disk device;

[0038] When the hard disk device receives a capacity query command, the hard disk device sends a capacity query command to another hard disk device connected to it, receives the capacity value returned by the other hard disk device, and modifies its own capacity value to its own capacity and outputting the sum of the capacity value returned by the other hard disk device;

[0039] And when receiving the data read-write name, judge whether the address of the data is its own address segment, if so, then access its own storage medium; if not, then send a read-wr...

Abstract

The invention discloses a hard disk device and a capacity integration method and system thereof. The hard disk device at least comprises two Ethernet interfaces, one Ethernet interface is connected with an Ethernet interface of the other hard disk device, and therefore when the hard disk device receives a capacity inquiry instruction, the hard disk device sends the capacity inquiry instruction to the other hard disk device and receives a capacity value returned by the other hard disk device, the capacity value of the hard disk device is revised as the sum of the capacity of the hard disk device and the capacity value returned by the other hard disk device, output is conducted, and the output capacity of the multiple connected hard disk devices is the sum of the capacities of the connected hard disk devices. When a read-write instruction of data is received, whether the address of the data is in the address field of the hard disk device or not is judged, and if yes, the hard disk device has access to storage media of the hard disk; if not, the read-write instruction is sent to the other hard disk device. Thus, large-capacity storage is achieved through the multiple hard disk devices.

Description

technical field [0001] The invention relates to the technical field of capacity integration, in particular to a hard disk device and its capacity integration method, and a hard disk device capacity integration system. Background technique [0002] The hard disk device of the prior art is more and more subject to people's favor because of its mobility and portability, and the user can copy the required files to the mobile hard disk device, and then connect with other computers as required to realize file transfer. transfer. [0003] With the development of Internet networks, people have higher and higher requirements on the capacity of hard disk devices. In order to realize the storage of large-capacity data, people continue to develop and achieve continuous breakthroughs in the storage capacity of hard disk devices. However, no matter the hard disk device with huge storage capacity is used, the cost of purchase, use and maintenance become very high, and no matter how the s...
