摘要： A method for managing read requests, the method may include receiving from a requesting entity a read request for reading an information unit stored in a storage system; determining by a control entity of the storage system whether the information unit is cached in a cache memory of the storage system and whether at least a predetermined number of disk drives of the storage system are currently overloaded; introducing a delay to a response to the read request thereby increasing a time difference between a time of the receiving of the read request and a time of a provision of the information unit to the requesting entity, if it is determined that the information unit is not cached in the cache memory and that the at least predetermined number of disk drives of the storage system are currently overloaded; and providing the information unit to the requesting entity.

摘要： The presently disclosed subject matter includes a method, system and apparatus, for dynamically controlling resource allocation in a storage system, the storage system comprises at least one storage device and at least one processing unit, the resources being associated with the processing unit. Responsive to a request from a connection for processing data, information in respect of an Allocation state of the processing unit is obtained. The Allocation state is defined as a Limiting Allocation state if the quantity of free resources associated with the processing unit, is lower than a first threshold value. In case the Allocation state of the processing unit is Limiting Allocation state, information in respect of a Connection state of the connection is obtained. The required memory resources are dynamically allocated to the connection according to the current Allocation state of the processing unit and the current Connection state of the connection.

摘要： There is provided a storage system comprising a control layer operable to manage a snapshot family (SF) constituted by SF members having hierarchical relations represented by a SF relationship data structure and a method of operating thereof. Upon receiving a command for restoring a writable SF member from a read-only snapshot thereof, the control layer provides a foreground atomic operation. The atomic operation comprises generating a new writable snapshot of the read-only snapshot (a destination SF member), modifying the SF relationship data structure, and re-assigning all logical unit numbers (LUNs) from the writable SF member to be restored to the destination SF member. Upon successful completion of the atomic operation, the control layer sends acknowledgement indicative of successful restoring the writable SF member. The control layer further provides a background process comprising modifying, in correspondence with the provided atomic operation, a SF mapping data structure comprising mappings between logical and physical addresses corresponding to SF members.

摘要： A system and method of operating a filesystem for managing filesystem objects is disclosed. The filesystem objects are characterized by metadata parameters included in a global directory object arranged in a plurality of global directory object (GDO) pages. Responsive to receiving a request for creating a new filesystem object, a parent key is obtained. The parent key is indicative of an identifier of a direct parent directory requested for hosting the new filesystem object. A target page that corresponds to the parent key is located within the plurality of GDO pages. The target page further includes a direct parent directory metadata record associated with the direct parent key and includes metadata parameters related to the direct parent directory. An object key is created as corresponding to the same target page, thereby enabling accommodation of an object metadata record, related to the new filesystem object, on the target page.
