Abstract
Some embodiments of the present invention provide a system that schedules read operations for disk drives in a set of disk drives. During operation, the system monitors a write rate for write operations to a given disk drive in the set of disk drives, wherein vibrations generated by the read operations directed to disk drives in the set of disk drives are transmitted to the given disk drive. Then, the read operations for disk drives in the set of disk drives are scheduled based on the write rate for the given disk drive, thereby limiting interference between the write operations and the vibrations generated by the read operations.
