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.

摘要:
A service controller for providing centralized service management, control and placement, as well as guaranteed failover, in a dynamic and distributed computing environment. The service controller works in conjunction with a computing resource supply manager, which supplies the required resources so that the service controller can run the service on the allocated resources. The number of active service instances may dynamically increase or decrease in accordance with changing availability of or demand for resources. The service controller monitors the service instances and takes appropriate action in the event of service instance failures. The service controller is provided with a service director component, which records and tracks, for each service instance which has been started on a particular resource/host, the IP address of such host, through a name location service, thus allowing end-users to locate the service regardless of where the service instances are physically running.
