Abstract: A first network apparatus for use in a cluster system is provided. A second network apparatus administers the first network apparatus and the at least one third network apparatus. The first network apparatus comprises a transceiver, a storage unit and a processor. The transceiver is configured to connect with the second network apparatus and the at least one third network apparatus, and to receive status information of the at least one third network apparatus. The storage is configured to store the status information.

Abstract: A storage system and an access control method thereof are provided. The storage system receives a first I/O request from at least one hypervisor. The first I/O request is used for accessing a first disk file of disk files. The storage system then operates a first I/O operation of a first virtual disk of virtual disks according to the first I/O request since the disk files correspond to the virtual disks. The storage system reads a QoS data of the first disk file and determines a first delay period according to the QoS data. The storage system transmits a first I/O response to the at least one hypervisor after the first delay period.

Abstract: A data distribution device and a data distribution method for use in a storage system including a plurality of storage servers are provided. The data distribution device includes a location recorder and a processor electrically connected with the location recorder. The location recorder is configured to record locations of a plurality of hypervisors and the storage servers. The processor is configured to capture information of at least one virtual machine related to the hypervisors; create a data distribution policy for the virtual machine according to the information and the locations of the hypervisors and the storage servers; and notify the storage system of the data distribution policy. The data distribution method is applied to the data distribution device to implement the aforesaid operations.

Abstract: A storage system and an operation method thereof are provided. The storage system comprises at least one independent storage device and at least one independent gateway device. The at least one independent storage device and the at least one independent gateway device are separated. The at least one independent storage device is configured to read in or read out data of at least one electronic device. The at least one independent gateway device is configured to control the access of the data between the at least one electronic device and the at least one independent storage device. The operation method is applied to the storage system to implement the aforesaid operations.
