First Claim
Patent Images
1. A storage control device, comprising:
- a storage unit configured to store therein a first score calculated for a first storage device; and
a processor configured toadd, upon detecting an event occurred in the first storage device, points corresponding to the event to the first score, anddetermine upon the addition, based on the first score and a second score, whether a sign of failure of the first storage device is detected, the second score being calculated for a first redundant unit of storage devices including the first storage device.

Abstract
A storage control device includes a storage unit and a processor. The storage unit is configured to store therein a first score calculated for a first storage device. The processor is configured to add, upon detecting an event occurred in the first storage device, points corresponding to the event to the first score. The processor is configured to determine upon the addition, based on the first score and a second score, whether a sign of failure of the first storage device is detected. The second score is calculated for a first redundant unit of storage devices including the first storage device.
