Abstract

In a RAID system, the power supplied to hard disks (HDDs) can be increased, and a plurality of types of HDDs can be installed. A plurality of HDD packs 33 are supplied with a single high voltage from a motherboard 28. The HDD packs 33 each accommodate, in a canister, an HDD 107, 181, 185 or 187 with different power supply specifications or communication interface specifications, as well as a DC/DC converter 109 to convert the power supply. Part of the HDD packs 33 have a data transfer interface conversion circuit 195 as well.

Claims

1. A storage system, which can be connected to a host computer, having:

a plurality of storage devices which store data from said host;

a plurality of housings in which said plurality of storage devices are mounted; and

a plurality of first power supplies which supply a voltage to said plurality of storage devices, and

wherein at least one of said plurality of housings has a first voltage converter which receives power having a first voltage value from said first power supply, converts said first voltage value into a second voltage value different from said first voltage value, and supplies power having a single voltage value to said storage device.
