1. A storage subsystem connected to a host computer via a communication network, said storage subsystem comprising: a plurality of storage apparatuses for storing data from said host computer;a plurality of DC power supplies, each of which is arranged in correspondence to a respective one of said storage apparatuses and supplies DC power to said one of said storage apparatuses via a respective main power supply wiring;a redundant DC power supply for generating, with any one of the storage apparatuses among said plurality of storage apparatus as a load, DC power to said load;a backboard with which said plurality of storage apparatuses, said plurality of DC power supplies and said redundant DC power supply are coupled to each other; andan auxiliary power supply wiring for guiding the output of said redundant DC power supply to each of said storage apparatuses;wherein said auxiliary power supply wiring includes: a common power supply wiring that is common to each of said DC power supplies;a plurality of branch power supply wirings that branch from said common power supply wiring, wherein, for each of said branch power supply wirings: the branch supply wiring is connected to a respective storage apparatus from the storage apparatuses via a respective DC power supply from the plurality of DC power supplies, such that the storage apparatus to which the branch supply wiring is connected is different from the storage apparatus to which the DC power supply supplies DC power; anda redundant power supply wiring for connecting said redundant DC power supply and said common power supply wiring. 2. The storage subsystem according to claim 1, wherein each of said DC power supplies and said redundant DC power supply include a malfunction detection circuit for stopping the supply of power to said load upon detecting a malfunction of said load. 3. The storage subsystem according to claim 1, wherein said auxiliary power supply wiring is configured by a back-flow prevention diode for preventing the inflow of current from a respective storage apparatus to become the load to said redundant DC power supply being inserted in correspondence to each of said storage apparatuses. 4. The storage subsystem according to claim 1, wherein each of said storage apparatuses and each of said power supplies are mounted on said backboard by being separated into multiple stages, and an air hole is formed at a corresponding portion between each of said storage apparatuses or between each of said power supplies on said backboard. 5. The storage subsystem according to claim 1, wherein each of said power supplies is arranged by being separated into the upper and lower parts of said backboard, and said auxiliary power supply wiring connecting said redundant power supply and each of said storage apparatuses is wired along the edge of said backboard. 6. A power supply system for supplying power to each of a plurality of storage apparatuses, comprising: a plurality of DC power supplies, each of which is arranged in correspondence to a respective one of said storage apparatuses and supplies DC power to said one of said storage apparatuses via a respective main power supply wiring;a redundant DC power supply for generating, with any one of the storage apparatuses among said plurality of storage apparatus as a load, DC power to said load;a backboard with which said plurality of DC power supplies and said redundant DC power supply are coupled to each other; andan auxiliary power supply wiring for guiding the output of said redundant DC power supply to each of said storage apparatuses;wherein said auxiliary power supply wiring includes: a common power supply wiring that is common to each of said DC power supplies;a plurality of branch power supply wirings that branch from said common power supply wiring, wherein, for each of said branch power supply wirings;the branch supply wiring is connected to a respective storage apparatus from the storage apparatuses via a respective DC power supply from the plurality of DC power supplies, such that the storage apparatus to which the branch supply wiring is connected is different from the storage apparatus to which the DC power supply supplies DC power; anda redundant power supply wiring for connecting said redundant DC power supply and said common power supply wiring. 7. The power supply system according to claim 6, wherein each of said DC power supplies and said redundant DC power supply include a malfunction detection circuit for stopping the supply of power to said load upon detecting a malfunction of said load. 8. The power supply system according to claim 7, wherein said auxiliary power supply wiring is configured by a back-flow prevention diode for preventing the inflow of current from a respective storage apparatus to become the load to said redundant DC power supply being inserted in correspondence to each of said storage apparatuses. 9. The power supply system according to claim 7, wherein each of said storage apparatuses and each of said power supplies are mounted on said backboard by being separated into multiple stages, and an air hole is formed at a corresponding portion between each of said storage apparatuses or between each of said power supplies on said backboard. 10. The power supply system according to claim 7, wherein each of said power supplies is arranged by being separated into the upper and lower parts of said backboard, and said auxiliary power supply wiring connecting said redundant power supply and each of said storage apparatuses is wired along the edge of said backboard.
