STORAGE SYSTEM AND ACCESS CONTROL METHOD THEREOF

摘要

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.

1. An access control method for use in a storage system, the storage system connecting to at least one hypervisor server and storing a plurality of disk files which correspond to a plurality of virtual disks respectively, the access control method comprising:
(a) enabling the storage system to receive a first I/O request from the at least one hypervisor, wherein the first I/O request is used for accessing a first disk file of the disk files; (b) enabling the storage system to operate a first I/O operation of a first virtual disk of the virtual disks according to the first I/O request; (c) enabling the storage system to read a quality of service (QoS) data of the first disk file; (d) enabling the storage system to determine a first delay period according to the QoS data; (e) enabling the storage system to transmit a first I/O response to the at least one hypervisor after the first delay period.
