Abstract
A storage system includes one or more first power supplies which receive power from the first input and supplies power to each of multiple load groups through multiple first paths and multiple second power supplies which receive power from the second input and supplies power to each of the multiple load groups through multiple second paths. Each load group is comprised of at least one load, and each load is a storage device. Power is supplied from different second power supplies respectively to two or more load groups to which power is supplied from the first power supply through two or more first paths.
Claims5
A storage system, comprising:
- a first to a fourth load groups (G1, G2, G8 and G4);
- and
- a first to a fourth power supplies (B1, B2, R1, and R2),
- wherein,
- (a1) the first power supply (B1) receives electric power from a first input, supplies electric power to the first load group (G1) via a first path (110A), and supplies electric power to the second load group (G2) via a second path (110B)
- (a2) the second power supply (B2) receives electric power from the first input, supplies electric power to the third load group (G3) via a third path (110C), and supplies electric power to the fourth load group (G4) via a fourth path (110D),
- (a3) the third power supply (R1) receives electric power from a second input, supplies electric power to the first load group (G1) via a fifth path (120A) and the first path (110A) connected to the fifth path (120A), and supplies electric power to the third load group (G3) via a six path (120C) and the third path (110C) connected to the six path (120C);
- (a4) the fourth power supply (R2) receives electric power from the second input, supplies electric power to the second load group (G2) via a seventh path (120B) and the second path (110B) connected to the seventh path (120B), and supplies electric power to the fourth load group (G4) via an eighth path (120D) and the fourth path (110D) connected to the eighth path (120D), according to the (a1) to (a4) configurations, it is possible to make load groups into power supply boundaries and to make power supply system to be redundant, with the same number of power supplies as the number of load groups (G1 to G4),
- wherein each load group (G1, G2, G3 and G4) is composed of a plurality of HDDs (Hard Disk Drives),
- wherein a RAID group is formed of a plural HDDs contained in the different load groups (G1, G2, G3 and G4),
- wherein the number of HDD composing each load group (G1, G2, G8 and G4) is the same, and
- wherein power supply capacity of each of the first to fourth power supplies is the same.
