The present invention relates to anoperation method of distributed memory disk cluster storage system, a distributed memory storage system is adopted thereby satisfying four desired expansions which are the expansion of network bandwidth, the expansion of hard disk capacity, the expansion of IOPS speed, and the expansion of memory I/O transmitting speed. Meanwhile, the system can be cross-region operated, data center and WAN, so the user's requirements can be collected through the local memory disk cluster for being provided with the corresponding services, the capacity of the memory disk cluster can also be gradually expanded for further providing cross-region or cross-country data service. |

1. An operation method of distributed memory disk cluster storage system, characterized in: firstly the installation of a distributed memory storage equipment includes a plurality of computer units for assembling a cluster scheme so as to form a cluster memory disk;
the computer unit is installed with a system virtual machine platform operation system, the computer unit is formed with a plurality of virtual machines, and the computer unit is used for setting the memory capacity occupying means through the operation system or a program software, so the memory is able to be planed as a storage device thereby forming as a plurality of chunk memory disks; a file is divided into one or plural data, one or plural copies are evenly distributed in the chunk memory disk, a memory bus with multiple channels is utilized for parallel accessing the memory module thereby allowing the capacity of the memory module to be planned for being used as a hard disk, wherein the access of the memory module supports all the file formats of the operation system, and a distributed storage scheme is utilized for allowing the data to be copied to one or more copies; when the operation system of the virtual machine directly accesses the required file through the CPU, the processed data is stored in the memory module, the memory used by the virtual machine for computing is also in the memory module, the computed data is directly stored in the original location of the memory module of the virtual machine operation system, so most of the data in the computer unit is able to be processed in the chunk memory disk with a parallel computing manner; the data which is not in the computer unit accesses the chunk memory disk of other computer unit through a network card being connected to a connection port cluster link; with respect to the assigned functions, each of the computer units is categorized to a first data center, at least a second data center and a backup center; wherein the first data center is provided with a virtual cluster data control station for controlling, wherein each of the second data centers is provided with a virtual cluster data backup station for controlling, and the backup center is provided with a virtual cluster data backup station for controlling, wherein the first data center and the second data center together form a distributed memory file system; moreover, a stack scheme is provided for expanding the storage capacity scheme, the access means of a network layer interface is utilized to plan the plural chunk memory disks of a computer unit to a resource pool of cluster memory disk unit with a cluster concept, and all the chunk memory disks are enabled to be synchronously operated for accessing data; when the cluster schemes are formed, each of the cluster schemes is able to be independently operated, and each of the cluster schemes is able to be served as a distributed memory disk cluster storage, the network layer interface is used for stacking, each of the distributed memory disk cluster storages is able to beused for simulating a chunk memory disk, a new cluster data control station and a new cluster data backup station are provided for controlling the amount of processed data to be distributed in all the chunk memory disks. |
