Data management architecture

A data management architecture comprising:

• a) an XOR engine;
• b) a host network interface coupled to said XOR engine and for coupling to a host computer system;
• c) a cache coupled to said XOR engine, said cache including a plurality of cache segments, each of said cache segments including i) a dual port memory array, ii) a bus expander coupled between said XOR engine and said dual port memory array, iii) a bus funnel coupled between said XOR engine and said dual port memory array, and iv) a buffer coupled between said storage device interface and said dual port memory;
• d) a storage device interface coupled to said cache and for coupling to a plurality of storage devices,
• wherein said XOR engine includes:
• a first transceiver coupled to said host network interface;
• logic means for i) generating in real time an XOR parity byte using said data and appending said parity byte to said data, ii) checking in real time XOR parity, and iii) correcting in real time detected parity errors;
• a second transceiver coupled to said cache.

A data management architecture comprising:

• a) an XOR engine which operates to generate in real time an XOR parity byte using said data and append said parity byte to said data, ii) check in real time XOR parity, and iii) correct in real time detected parity errors;
• b) a host network interface coupled to said XOR engine and for coupling to a host computer system;
• c) a cache coupled to said XOR engine;
• d) a storage device interface coupled to said cache and for coupling to a plurality of storage devices.
