System, method and a non-transitory computer readable medium for read throtling

A non-transitory computer readable medium that stores instructions to be executed by a computer for:

• receiving from a requesting entity a read request for reading an information unit stored in the storage system;
• determining by a control entity of a storage system whether the information unit is cached in a cache memory of the storage system and whether at least predetermined number of disk drives of the storage system is 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 application if it is determined that the information unit is not cached in the storage system and that the at least predetermined number of disk drives storage system is currently overloaded;
• and
• providing the information unit to the requesting entity.

A system comprising:

• multiple disk drives;
• a cache memory;
• and
• a control entity that is arranged to:
• receive from a requesting entity a read request for reading an information unit stored in the storage system;
• determine whether the information unit is cached in the cache memory of the storage system and whether at least a predetermined number of disk drives of the multiple disk drives is currently overloaded;
• introduce 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 application if it is determined that the information unit is not cached in the storage system and that the at least the predetermined number of disk drives of the storage system is currently overloaded;
• and
• control a provision of the information unit to the requesting entity.
