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.

Storage system storing a plurality of disk files which correspond to a plurality of virtual disks and access control method thereof

A method for performing Simple Storage Service (S3) seamless migration using index objects and associated apparatus are provided. The method includes: in response to a request of migrating user data of a user of the storage server from a remote S3-compatible server into the storage server, during an index stage, utilizing an index-object-based S3 migration management module among multiple program modules running on a host device within the storage server to create and store multiple index objects into a storage device layer of the storage server to be respective representatives of multiple normal objects of the user data at the storage server, and migrate respective Access Control Lists (ACLs) of the multiple normal objects to the storage server to be respective ACLs of the multiple index objects; and during a data stage, utilizing the index-object-based S3 migration management module to trigger one or more migration agents to migrate object data.

Method and apparatus for performing simple storage service seamless migration using index objects

A method for performing pipeline-based accessing management in a storage server and associated apparatus are provided. The method includes: in response to a request of writing user data into the storage server, utilizing a host device within the storage server to write the user data into a storage device layer of the storage server and start processing an object write command corresponding to the request of writing the user data with a pipeline architecture of the storage server; utilizing the host device to input metadata corresponding to the user data into at least one pipeline within the pipeline architecture; and utilizing the host device to cache the metadata with a first cache module of the pipeline, for controlling the storage server completing the request without generating write amplification of the metadata, wherein the first cache module is a hardware pipeline module outside the storage device layer.

A device and a method for virtual storage are provided. The device includes a physical processor, a hypervisor and a physical storage. The hypervisor is executed on the physical processor and configured to create at least one client virtual machine and a controller virtual machine. The physical storage is clustered with physical storage of at least another device via the controller virtual machine to form a storage cluster. The controller virtual machine is further configured to define a virtual storage pool in the storage cluster and create at least one virtual storage controller virtual machine to interface the at least one client virtual machine with the virtual storage pool so that the at least one client virtual machine accesses the virtual storage pool via the at least one virtual storage controller virtual machine and the controller virtual machine. The method is applied to the device to implement the operations.
