Various changes to the described embodiments four desired expansions which are the expansion of network may be made in the function and arrangement of the elements bandwidth, the expansion of hard disk capacity, the expansion described without departing from the scope of the invention of IOPS speed, and the expansion of memory I/O transmitting as set forth in the appended claims. speed. Meanwhile, the system can be cross-region operated, [0037] Referring from FIG. 1, the present invention pro data center and WAN, so the user’s requirements can be vides an operation method of distributed memory disk cluster collected through the local memory disk cluster for being storage system, wherein one preferred embodiment for illus provided with the corresponding services, the capacity of the trating the operation method of distributed memory disk clus memory disk cluster can also be gradually expanded for fur ter storage system is as following: ther providing cross-region or cross-country data service. [0038] The installation of a distributed memory storage [0031] With the increased quantity of the storage devices, equipment includes a plurality of computer units (10) for increasing one server would have the network bandwidth and assembling a cluster scheme (1) so as to form a cluster the disk capacity being correspondingly accumulated thereby memory disk; wherein the computer unit (10) is installed with forming a resource pool, the distributed memory disk cluster a CPU, at least a memory, at least a hard disk, at least a storage is served like a physical hard disk, so the whole network card, a mother board, an I/O interface card, at least a operation would not be affected due to one of the physical connection cable and a housing. [0039] The computer unit (10) is installed with a system mainframes being failed, the chunk memory disk in the copy virtual machine platform operation system, so the computer could copy the stored data to a new chunk memory disk, so a unit (10) is formed with a plurality of virtual machines, and fundamental data backup is maintained, meanwhile the con the computerunit (10) is used for setting the required machine tinuous data protector (CDP) is also adopted for providing memory resource capacity, the operation system is used for novel service of data backup and recovery, thus the disadvan setting the memory capacity occupying manner, or a program tages of the tape backup often being failed and the backup software is utilized for planning the memory to a hard disk only being performed once a day are improved. device for forming as a chunk memory disk (11) which is the [0032] In addition, the data generated through the copy can same as the tracks of a hard disk. be sent from different chunk memory disk thereby achieving [0040] As such, a file is enabled to be divided into one or the many-to-one data transmission, when the user amount plural data, and the file size can bed. MB or bigger, one or increases, only increasing the quantity of the chunk memory plural copies are evenly distributed in the chunk memory disk disk can achieve the many-to-many transmission, so the dis (11), so the data is actually stored in a memory module, and a advantages of the multiple RAID hard disks crashing causing memory bus with multiple channels is utilized for parallel the whole data being missed, the limitation of the quantity of accessing the memory module thereby allowing the capacity network interface of storage device and the network speed of the memory module to be planned for being used as a hard causing the excessive data being overly jammed and delayed disk, wherein the access of the memory module supports all for transmitting, the expansion of LUN and the data center the file formats of the operation system, and a distributed being unable to be cross-region operated can be solved; the storage scheme is utilized for allowing the data to be copied to present invention adopts the memory being served as a disk, one or more copies, with the above-mentioned method, the each file or each virtual machine can be stored in the memory data center can still be operated even if the machine is broken with a file format, the highest I/O speed of the memory bus and/or the data center is damaged. can be directly utilized, the data can be transmitted between [0041) Each copied data can be encrypted through mixing the CPU and the memory, the highest I/O number, distance the 1-4096 bit AES and RSA for being stored in the memory, and speed can be provided. Accordingly, the present invention when the data is desired to be accessed, the data is transmitted is novel and more practical in use comparing to prior art. between the memory and the CPU thereby minimizing the US 2015/0160872 A1 Jun. 11, 2015 I/O accessing times and distance, the virtual machine is and the data access speed and the data liability can also be formed as a file format for being stored in the memory mod increased, and the above-mentioned can be gradually ule, the memory capacity planned for the virtual memory is increased according to the user’s desire. also in the same sector. [0048] When the cluster schemes (1) are formed, each of [0042] When the operation system
