System and method of management of multi-tier storage systems

A method of managing a plurality of storage tiers by at least one processor, method comprising:

• receiving at least one write-access request, comprising at least one of a data element for storage, a logical address associated with the data element and a tier identifier for a selected tier,
• computing a unique reference name based on the content of the at least one data element, and associating the unique reference name with the logical address;
• generating a first write-access command, comprising the unique reference name and the at least one data element;
• customizing the first write-access command according to at least one characteristic of the selected tier by a driver associated with the selected tier, to obtain at least one second write-access command;
• using the second write-access command to associate the unique reference name with at least one physical location on the selected tier, and
• storing the at least one data element at the associated at least one physical location.

A system for managing a plurality of storage tiers, the system comprising:

• a non-transitory memory device, wherein modules of instruction code are stored, and a processor associated with the memory device, and configured to execute the modules of instruction code, whereupon execution of said modules of instruction code, the processor is further configured to perform at least one of:
• receive at least one DMO command, comprising at least one logical address of a respective at least one data element;
• obtaining a unique reference name associated with the logical address;
• generating a global DMO command that comprises the unique reference name and is dissociated from the logical address;
• customizing the global DMO command according to at least one characteristic of a specific storage tier of the plurality of storage tiers to obtain a tier-specific DMO command;
• and
• applying the tier-specific DMO command on the specific storage tier.
