Abstract: A storage clustering system comprises storage front-ends and clustering modules. At least one clustering module receives an access command from a client. When the access command instructs that a data item be stored, a clustering module invokes at least one computing module to compute at least one derivative value of the data item, and at least one clustering module stores, based on an index, the derivative value or at least part of the data item through a storage front-end, and accordingly updates an instance of metadata. When the access command instructs that a data item be fetched, a clustering module examines the metadata to select a storage front-end, through which a clustering module fetches the data item. When the storage front-end returns a derivative value instead, the fetching clustering module examines the index according to the derivative value to synthesize the data item for the client.

Abstract: Disclosed herein is a block storage gateway module comprising a receiver unit and an access unit. The receiver unit intercepts an operating system call indicating a local access to a storage volume in order to generate a proximal access command. The access unit proximally accesses a storage array based on the said command. The storage array corresponds to the storage volume; the proximal access corresponds to the local access. Also disclosed herein is a mediator system for storage, the system comprising a load balancer device and one or more storage resource devices. Each storage resource device comprises an aforementioned module and a daemon module. The load balancer device receives a remote access request, selects one storage resource device, and sends an address of the selected storage resource device in a grant message.

Abstract: Disclosed herein is an input/output (I/O) redirection method, comprising receiving a call from a virtual machine for a first procedure, selectively executing the first procedure, and selectively calling a second procedure based on an external arrangement. The first procedure is associated with an I/O operation on the virtual machine and executed when the external arrangement indicates that the second procedure not be called. The second procedure is called when the external arrangement indicates so, and executed outside of the virtual machine. Also disclosed is an I/O virtualization system, comprising a front-end module and a back-end module. The front-end module, disposed in an operating system of the virtual machine, calls the first procedure based on the I/O operation. The back-end module, disposed in a hypervisor managing the virtual machine, is configured to implement the said method. The said system may further comprise a device configured to execute the second procedure.
