Method and system for expanding capacity of memory device

Abstract

The invention relates to a method and a system for expanding the capacity of a memory device. The method for expanding the capacity of a memory device comprises the following steps of connecting a plurality of memory devices to form a memory device group and is characterized by further comprising the steps of: recording the connecting address of each memory device and all available ID numbers of a basic memory cell of the memory device; distributing and recording the unique virtual ID number for each basic memory cell; associating each virtual ID number with the connecting address of the corresponding memory device and the ID number of the basic memory cell; and accessing to the corresponding basic memory cell via the virtual ID number. The invention also discloses a system for realizing the method. The invention ensures that a plurality of memory devices are virtualized to form a large hard disc with the capacity being equal to the total capacity of the plurality of memory devices, thereby realizing the unlimited expansion of the memory capacity, greatly improving the memory capacity and realizing the network memory.

Description

technical field [0001] The invention belongs to the technical field of data storage, and relates to a storage control method and system for a storage device, in particular to a method and a system for expanding the storage capacity of a storage device. Background technique [0002] Data storage is often realized by storage devices such as disks (especially hard disks). Of course, storage devices are not limited to disks, but also include electronic hard disks, Flash flash drives, optical storage devices, floppy disk drives with floppy disks, and other data storage devices. Functional equipment, etc., as well as computers connected to storage devices, storage servers, etc. [0003] As we all know, the data of ordinary hard disk is stored in the storage medium of the hard disk—on the disk, and its basic storage unit is sector (Sector), and the data is stored in each sector. Each sector is numbered, that is, the sector number, and each sector number (whether it is a physical s...

Problems solved by technology

On the one hand, these network storage methods all have the above-mentioned storage defects, and at the same time, there are defects such as insufficient utilization of network bandwidth, low operating efficiency, and often inability to "secondary sharing" of network storage devices.
