Preventing damage of storage devices and data loss in a data storage system
First Claim
Patent Images
1. A data storage system, comprising:
- an interconnect component including one or more processors;
a group of storage components, each storage component comprising a controller, one or more fans, and a plurality of disk drives;
wherein the controller of each storage component is operable to;
increase a fan speed if the controller detects a temperature of an overheating disk drive over a first threshold;
remove the overheating disk drive from data storage operations if the controller detects the temperature of the overheating disk drive over a second threshold after the fan speed is increased, wherein the second threshold is greater than the first threshold; and
temporarily activating the overheating drive so that data can be evacuated from the overheating disk drive to one or more properly functioning disk drives; and
wherein the interconnect component is operable to transfer data from the overheating disk drive to the one or more properly functioning disk drives.

9. A method of minimizing disk drive failures and data loss in a data storage system comprising an interconnect component and one or more storage components each comprising disk drives, a fan, and a controller, the method comprising:
-
detecting an overheating disk drive within a storage component with the controller; increasing a fan speed with the controller if the overheating disk drive is detected; removing the overheating disk drive from data storage operations, with the controller, if after the fan speed is increased the overheating disk drive is still overheating; evacuating data from the overheating disk drive by temporarily activating the overheating drive and transferring the data to another disk drive. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
