Background technology
A hard disk drive is a kind of non-volatile memory device, and data storage is on high speed rotating rigidity magnetic surface.Flash memory is owing to its high density, non-volatile and come into vogue with respect to the hard disk drive size is less.Flash memory is based on the technology of EPROM and EEPROM.Why using " flash memory " this speech, be because there is a large amount of storage unit can be by disposable deletion, and EEPROM need delete separately on the contrary to each byte.Flash memory comprises two types of NOR flash memory and nand flash memories.Nand flash memory is owing to the storage array of its more compact structure has higher density.The flash memory of indication is considered to be the flash memory that uses NOR or nand memory or other types in the utility model.
Ready-made flash memory device is unfavorable for constituting mass-memory unit on the market, and these ready-made flash memory devices have lower performance, low reliability, low capacity and lower bandwidth compared with traditional mass-memory unit.Flash memory device ready-made on the market is normally made by the nand flash memory of multi-level unit, and it has lower read/write speed, lower reliability, than low capacity and lower bandwidth.
Solid state hard disc in the market (SSD) adopts solid-state memory to store persistant data.Most of solid state hard disc manufacturer uses nonvolatile memory.Solid state hard disc based on flash memory does not have moving-member, therefore for ignoring in traditional dynamo-electric disk intrinsic addressing and otherwise time delay.Single NAND chip speed is slower, and reason is narrow and small relatively asynchronous IO interface.In order to reach high performance SSD, must be to the nand flash memory chip use that walks abreast.Solid state hard disc (SSD) is a kind of substitute of more reliable, more effective and more expensive hard disk drive.
Up to date, based on the solid state hard disc or the too expensive of flash memory, to such an extent as to cannot widespread use in mobile computing.In addition, solid state hard disc also has the defective that can not expand.
How utilizing existing flash memory device, constitute a kind of with low cost and memory device with extensibility, is a difficult problem that needs to be resolved hurrily in the market.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of flash memory bunch device is provided, and can be the user higher capacity, higher reliability, better portable, higher dirigibility and cheaper cost are provided.
The technical solution of the utility model is: the utility model has disclosed a kind of flash memory bunch device, and with a plurality of flash arrays and/or the flash memory hub links together and can be by the host platform access, this flash memory bunch device comprises:
Flash memory bunch control module, for the Local or Remote user provides this flash memory of the configuration bunch flash array that device is connected and/or the function of flash memory hub are installed, make this flash memory bunch device and the flash array and/or the flash memory hub that are connected constitute storage subsystem together through handling;
Flash memory bunch host access port provides the interface of this flash memory of access bunch device for main frame;
Flash memory bunch interconnect port provides interface for bunch device stack of a flash memory is interconnected to another flash memory bunch device;
Flash memory bunch port, the interface of access is provided for a plurality of flash memory hubs and/or flash array, if this flash memory bunch flash memory hub that port connected is in state of activation, then this flash memory bunch port arrangement is the access interface of flash memory hub, if this flash memory bunch flash memory hub that port connected is in unactivated state, then this flash memory bunch port arrangement is the access interface of flash array.
According to an embodiment of flash memory of the present utility model bunch device, the processing in the flash memory bunch control module comprise to this flash memory bunch device and the flash array and/or the flash memory hub that are connected connect, the operation of redundant array, mirror image, array.
According to an embodiment of flash memory of the present utility model bunch device, this flash memory bunch device also comprises:
Power module is for a flash memory bunch device provides electric power.
According to an embodiment of flash memory of the present utility model bunch device, this flash memory bunch device also comprises:
Pcb board, this flash memory bunch control module, this flash memory bunch host access port, this flash memory bunch interconnect port and this flash memory bunch port are positioned on this pcb board.
According to an embodiment of flash memory of the present utility model bunch device, this flash memory bunch host access port and this flash memory bunch interconnect port are WiFi port, ethernet port or USB port.
The utility model contrast prior art has following beneficial effect: the utility model provides the interface of access for a plurality of flash memory hubs and/or flash array by flash memory bunch port, provide the interface of access flash memory bunch device by flash memory bunch host access port for main frame, thereby make that flash memory bunch device can with a plurality of flash arrays and the flash memory hub links together and can be by the host platform access.Contrast prior art, the utility model utilize ready-made flash memory (as thumb flash memory device, SD card and miniature SD card) to reach the requirement of low-cost storage as storage subsystem.The flash memory of the present utility model bunch advantage that device is maximum is its extensibility, and the user can expand and this memory storage of upgrading according to the needs of self.This memory storage can place of hard disk drive or the memory device of solid state hard disc.
