摘要： A storage system and method is provided including physical storage devices controlled by storage control devices constituting a storage control layer operatively coupled to the physical storage devices and hosts. The storage control layer includes a first virtual layer interfacing with the hosts, operable to represent a logical address space available to said hosts and characterized by an Internal Virtual Address Space (IVAS); a second virtual layer characterized by a Physical Virtual Address Space (PVAS), interfacing with the physical storage devices, and operable to represent an available storage space; and an allocation module operatively coupled to the first and second virtual layers and providing mapping between IVAP and PVAS. Each address in PVAS is configured to have a corresponding address in IVAS. The allocation module facilitates management of IVAS and PVAS, enabling separation of a process of deleting certain logical object into processes performing changes in IVAS and PVAS, respectively.

摘要： A method of migrating data from a source storage resource to a destination storage resource involves selecting a source volume in the source storage resource; configuring in the destination storage resource a destination volume corresponding to the source volume and having the same properties; and redirecting I/O requests from an application running on a host to the destination volume instead of the source volume, whilst migrating data stored in the source volume to the destination volume. A storage system is operable as a destination storage system for migrating data from a source storage system, including means for configuring a destination volume corresponding to a source volume in the source storage system and a migration module having a non-transitory computer useable medium and operable to initiate read requests addressed to the source volume thereby enabling a background process of migrating data stored in the source volume to the destination volume.

摘要： Accessing data memory includes writing data to a first memory location and to a second memory location in response to a request to write data to a memory address that corresponds to both locations, where the first and second memory locations are mirrored, in response to a request to read data from the memory address, reading data from the first memory location or the second memory location based on load balancing, and accessing data from the second memory location in response to a request to access data at the memory address when memory hardware corresponding to the first memory location has failed. Accessing the data memory may include requesting access to a specific one of the first and second memory locations. The memory address may contain a portion that is common to both the first memory location and the second memory location. Hardware coupled to the memory may cause data written using the memory address to be automatically written to the first memory location and the second memory location.

摘要： Storage systems with reduced energy consumption, methods of operating thereof, corresponding computer program products and corresponding program storage devices. Some non-limiting examples of a write method include: configuring a plurality of storage disk units such that at any given point in time there are at least two storage disk drives operating in active state in any storage disk unit; caching in a cache memory one or more write requests and generating a consolidated write request corresponding to a stripe in a RAID group; destaging the consolidated write request; and writing the destaged consolidated write request in a write out of place manner to one or more storage disk drives operating at the destage point of time in active state. Some non-limiting examples of a read method include: configuring local storage disk drives so that at any given point in time, a part of the local storage disk drives operates in low power state, wherein the local storage disk drives are operable to switch between low power state and active state; and responsive to a read request for a portion on a local storage disk drive, reading from the local storage disk drive, if active; and if the local storage disk drive is not active, enquiring if a remote mirror storage disk drive storing a copy of the portion is active, and if yes, reading from the remote mirror storage disk drive.
