STATISTIC-BASED ISOLATION OF LETHARGIC DRIVES |
| 摘要 |
A method is provided for identifying a lethargic drive. The method includes executing a command directed to at least two drives in a redundant array of independent disks (RAID) configuration. Each of the drives of the at least two drives is associated with a plurality of timing buckets. The method also includes determining a completion time of the command, and, for each of the at least two drives that the command was directed to, counting the completion time of the command in one of the timing buckets associated with the drive. |
