Storage system, storage appliance and control appliance

Abstract

The invention discloses a storage system, a storage appliance and a control appliance. The storage system comprises the control appliance and at least two storage appliances, wherein the control appliance comprises a system controller and a converter, the converter is connected with the system controller, and in addition, the converter is provided with at least two first interfaces, wherein at least two first interfaces are single-passage serial microcomputer system interfaces, or at least two first interfaces are peripheral element expansion x1 interfaces, each storage appliance comprises a connector and a storage unit, each connector comprises a second interface and a third interface, the second interface of each connector is connected with a first interface of the converter, and a third interface of the connector is connected with the storage unit, so the two storage appliances are parallelly connected with the control appliance. Through adopting the mode, the parallel connection of the storage appliance to the control appliance can be realized, the access time delay of the partial storage appliance is reduced, and the storage volume expansion of the storage system is convenient.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a storage system, a storage device, and a control device. Background technique [0002] With the development of information technology, especially the development of network technology, the amount of electronic data has shown a geometric growth. The way of storing electronic data with a single hard disk can no longer meet the storage requirements of big data. At present, large data is generally stored in a storage array composed of multiple hard disks. In actual application, as the business expands and the amount of data increases, when the storage capacity of the current storage array cannot meet the requirements, the storage array can also be expanded to increase the storage capacity. Therefore, the storage array needs to have good scalability while having good reliability and maintainability. [0003] see figure 1 , figure 1 It is a schematic structural diagram of a stora...

AI Technical Summary

Problems solved by technology

[0004] The storage array in the prior art adopts a serial networking method. With the increase of the storage array, the access delay increases step by step, which affects the access speed

And because there are two positive and negative serial connections, when it is necessary to increase the storage array for capacity expansion, a cable of the original business must be unplugged before the new storage array can be inserted, which will have a certain impact on the original business

Furthermore, because 4Lane SAS cables are used to connect storage arrays, and 4Lane SAS cables are hard and thick, so it is not convenient to route cables on site, and the distance of cables is relatively short.
