Abstract
A storage method, a storage system, and a controller are disclosed. The method is applicable to a system that includes at least one controller, at least two Peripheral Component Interconnection Express (PCIE) Input/Output (IO) modules, and at least two storage devices. The at least two storage devices are connected through a PCIE switch chip of the at least one controller, and the at least two PCIE IO modules are connected through a PCIE switch chip of the at least one controller. The method includes: receiving a request message from a server through the at least two PCIE IO modules; and accessing the at least two storage devices according to the request message. The at least two PCIE IO modules are shared between controllers, thereby saving resources; and the storage devices access the controllers without the need of a hard disk controller or a hard disk extension chip, thereby saving costs.
