System and method for providing data redundancy after reducing memory writes

A computer program product embodied on a computer readable medium, comprising:

• computer code for reducing a number of writes to a storage subsystem;
• computer code for providing data redundancy utilizing a data redundancy scheme, after the reducing;
• and
• wherein the writes are received from a computer via a standard storage subsystem interface, the data redundancy scheme is implemented by a disk controller and comprises storing data associated with the reduced number of writes in a plurality of primary flash memories and storing computed redundant information in at least one redundant flash memory, and the disk controller is enabled to operate without a loss of data in the presence of at least a single failure of any of the flash memories.

An apparatus, comprising:

• a circuit enabled to receive writes from a computer via a standard storage subsystem interface, and further enabled to reduce a number of the received writes;
• a disk controller that implements a data redundancy scheme comprising storing data associated with the reduced number of writes in a plurality of primary flash memories and storing computed redundant information in at least one redundant flash memory;
• and
• wherein the disk controller is enabled to operate without a loss of data in the presence of at least a single failure of any of the flash memories.
