Abstract
A data processing system (1) comprising distributed data storage resource (D1-D3, FD6, TL4, STOe) under the control of a distributed management unit (DSM1 through DSM6), which may or may not be associated with a server (S1 through S3) . This unit receives, from a centralized management unit (NSM), control programs which dynamically allocate to the unit to a virtual memory space comprising local storage units and all or some of the external storage resources.
Claims32
A data processing system (10) comprising a plurality of distributed data storage units (D1-D3, FD6, TL4, STOe) and at least one data storage server (S1-S3) connected to a network for storing data,
- a plurality of distributed management units (DSM1-DSM6) connected to one another to form a memory for local data storage and having memory space addressable by a protocol comprising input-output read-write instructions sent by a data storage server (S1-S3), wherein at least some of said distributed data storage units (D1-D3, FD6, TL4, STOe) are operatively associated with said data storage server (S1-S3) via one respective distributed management units (DSM1-DSM6), and
- an allocation unit arranged to allocate to each of said data storage servers (S1-S3) a virtual memory space (D′xyz) whose extent is at least equal to the accumulated capacity of at least some of said distributed data storage units (D1-D3, FD6, TL4, STOe).
A data processing system (10) comprising a plurality of distributed data storage units (D1-D3, FD6, TL4, STOe) and at least one data storage server (S1-S3) connected to a network for storing data, an allocation unit arranged to allocate to each of said data storage servers (S1-S3) a virtual memory space (D′xyz) whose extent is at least equal to the accumulated capacity of at least some of said distributed data storage units (D1-D3, FD6, TL4, STOe), data processing centralized management units (NSM) connected to one another and associated with a data base (CDB) of data describing at least the configuration of said distributed data storage units (D1-D3, FD6, TL4, STOe), said data processing centralized management (NSM) including a unit for developing and downloading programs from said data into distributed management program units (DSM1-DSM6), such that the distributed management program units, when associated with a data storage server (S1-S3), allocate to said storage server (S1-S3), under the control of a downloaded program, said virtual memory space (D′xyz).
