SYSTEM, METHOD AND A NON-TRANSITORY COMPUTER READABLE MEDIUM FOR A PRE-FETCH OPERATION

摘要

A method for pre-fetching information units, the method may include: (I) Receiving, by a storage system, write requests for writing information units to the storage system. Each write request includes a first identifier and a second identifier. The first identifier identifies a logical address. A combination of the first and second identifiers identifies an accessing entity that initiated the write request. (II) Receiving a read request for reading at least one information unit from the storage system, the read request is initiated by a certain accessing entity. (III) Determining whether to perform a pre-fetch of at least one additional information unit in response to at least one write request that was initiated by the certain accessing entity. If is determined to perform the pre-fetch then fetching the at least one additional information unit.

1. A method for pre-fetching information units, the method comprises:
receiving, by a storage system, write requests for writing information units to the storage system; wherein the write requests are initiated by multiple accessing entities;
wherein each write request comprises a first identifier and a second identifier; wherein the first identifier identifies a logical address within a logical address space supported by the storage system and wherein a combination of the first and second identifiers identifies an accessing entity that initiated the write request; receiving a read request for reading at least one information unit from the storage system, the read request is initiated by a certain accessing entity of the multiple accessing entities; determining whether to perform a pre-fetch of at least one additional information unit in response to at least one write request that was initiated by the certain accessing entity; and if is determined to perform the pre-fetch then fetching the at least one additional information unit.
