<p><P>PROBLEM TO BE SOLVED: To realize energy and space saving by reducing electric power loss and setting electric power capacity of backup power supply at the optimum value in a disk array apparatus. <P>SOLUTION: A secondary battery box 87, a non-insulation type DC/DC converter 89 and an HDD 91 are implemented in HDD boxes 83<SB>1</SB>to 83<SB>n</SB>, and the secondary battery box 87, high-speed response type non-insulation DC/DC converters 93<SB>1</SB>to 93<SB>3</SB>and loads 95<SB>1</SB>to 95<SB>3</SB>are implemented on logic circuit boards 85<SB>1</SB>to 85<SB>n</SB>. Each of the secondary battery box 87 has a charge/discharge circuit 97 and a series body 99 of a plurality of secondary batteries. In the HDD box, output voltage of the secondary battery box 87 is supplied to the HDD 91 through the DC/DC converter 89. On the logic circuit board, output voltage of the secondary battery box 87 is supplied to each of the corresponding loads 95<SB>1</SB>to 95<SB>3</SB>through the DC/DC converters 93<SB>1</SB>to 93<SB>3</SB>. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
