As shown in Figure 1, the novel storage control node architecture based on the fusion architecture dual redundancy of the present invention includes a control module, a disk connection module, an application access module, a management module, a fan module, a power supply module and a battery module 7 Part, wherein: the control module is the core component of the entire storage controller system, the control module is first responsible for the stable operation of the entire system, secondly the control module receives and processes the application data requests from the front-end application server equipment, and finally the control module is used for cascading The disk storage cabinet at the back end is used to realize the unified writing or reading management of data in multiple storage cabinets at the back end. Considering the importance of the control module, two controllers are designed as mutual backup in the entire system to improve the overall system The redundancy can well avoid the problem that the system stability is affected by the failure of a single controller;

Four disk connection modules are designed in the whole system, and each disk connection module provides two miniSAS cascading ports with a transmission rate of 6Gbit/s for cascading hard disk enclosures. The disk connection module is connected to the back-end hard disk array of the storage system through miniSAS cables. When the transmission rate of the connected device is lower than the rate of the cascade port, the cascade port will automatically adapt to the transmission rate to ensure the connectivity of the data transmission channel and the consistency of the data transmission rate.

6 application access modules are designed in the whole system. The application access module provides the service interface between the application server and the storage system, and is used to receive the data read and write instructions issued by the application server. The application access module is divided into FC application according to the interface There are two types of interface modules and iSCSI interface modules, among which the FC application interface module provides a back-end cascading port with a transmission rate of 4Gbit/s and a host port of 8Gbit/s. The iSCSI interface module is divided into two types according to the interface rate: 1Gb and 10Gb. The 1GbiSCSI interface module provides 4 iSCSI interfaces with a transmission rate of 1Gbit/s for receiving data exchange commands issued by the application server. The 10GbiSCSI interface module provides 2 iSCSI interfaces with a transmission rate of The 10Gbit/s iSCSI interface is used to receive data exchange commands issued by the application server.

The management module provides management interfaces for the storage system, mainly including management network ports and serial ports. The management module saves the system configuration data, alarm information and log information to the SSD safe hard disk. In terms of redundancy, the entire system uses two management modules. When one module fails, the other module can immediately take over the work to ensure the stability of the management network in the architecture system.

In this architecture, 4 battery modules are specially designed. The battery modules can provide backup power support when the external power supply of the system fails, so as to ensure the security of business data in the storage array. It is in the backup state when the system power output is normal, and when the external power supply is disconnected, the battery module can continue to supply power to the system. The battery module supports failure isolation, and when the battery module fails, it will not affect the normal operation of the system.

The front part consists of 4 battery modules and 2 control modules; the rear part consists of 4 power modules, 3 fan modules, 2 management modules, 4 disk connection modules and 8 application access modules. The middle part is the backplane, which is used to connect the above-mentioned front and rear modules for connection. The entire modular design can facilitate daily disassembly and assembly operations, not only physically isolates the fault point, but also supports hot-swappable operation for all modules, which is convenient for maintenance.

The connection port is used for cascading disk enclosures. The SAS expansion unit is connected to the back-end hard disk array of the storage system through miniSAS cables. When the transmission rate of the connected device is lower than the rate of the cascade port, the cascade port will automatically adapt to the transmission rate to ensure the connectivity of the data transmission channel and the consistency of the data transmission rate. Each control module will lead to two 1Gbit/s network links to connect with the management module in the system respectively. The management module provides a management interface for the storage system, mainly including the management network port and serial port. The management module is mainly responsible for system configuration data , alarm information and log information records.
