摘要： A method for service level agreement allocation of permanent storage layer resources of a storage system, the method may include monitoring, by a control layer of the storage system, actual performances of the storage system that are related to multiple logical volumes; calculating actual-to-required relationships between the actual performances and service level agreement defined performances of the multiple logical volumes; allocating, for different logical volumes of the multiple logical volumes, allowable amounts of pending access requests; wherein the allocating is based on, at least, the actual-to-required relationships; receiving, by the control layer, received access requests aimed to one or more logical volumes of the logical volumes; and sending to the permanent storage layer requests to serve at least some of the received access requests, based on the allowable amounts of pending access requests.

摘要： A method for controlling compression based on compression ratio, the method includes monitoring access requests related to a storage entity of a storage system; wherein the access requests are associated with multiple data units; evaluating a compression ratio related to the storage entity; wherein the evaluating comprises applying a first compression process on at least a subset of the multiple data units to provide first compressed data units; serving the access requests without storing, in a permanent storage layer of the storage system, the first compressed data units; and reacting, by the storage system, to the compression ratio.

摘要： A method for de-duplication, the method may include receiving a request to store in a storage system a received data entity; obtaining a received data entity signature that is responsive to the received data entity; selecting a selected data structure out of a set of data structures that comprises K data structures; wherein K is a positive integer; wherein for each value of a variable k that ranges between 2 and K, a stored data entity signature that is stored in a k'th data structure out of the set collided with stored data entity signatures that are stored in each one of a first till (k−1)'th data structures of the set; calculating an index by applying, on the received data entity signature, a hash function that is associated with the selected data structure; determining whether an entry that is associated with the index and belongs to the selected data structure is empty; writing to the entry, if the entry is empty, the received data entity signature, and storing the received data entity in the storage system in response to a location of the entry in the set; selecting, if (a) the entry is not empty and (b) the received data entity signature differs from a stored data entity signature that is stored in the entry, a new data structure of the set, and repeating at least the stages of calculating and determining.

摘要： There is provided a storage arrangement and a method of operating thereof. The storage arrangement comprises a first storage system and one or more second storage systems operatively coupled to the first storage system. First control layer is operable to handle a first logical address space comprising a first logical group characterized by a plurality of logical block addresses; first control layer comprises a first mapping module handling a first mapping structure associated with first logical group. Each second control layer comprises, respectively, a second mapping module handling a second mapping structure associated with first logical group. The first mapping structure is configured to provide mapping between logical addresses related to first logical group and corresponding addresses related to first physical address spaces, and/or to point to respective second mapping structure configured to provide mapping between these logical addresses and corresponding addresses related to respective second physical address spaces.

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.
