Preventing Damage to Storage Devices within a Storage System Due to Movement of the Storage System

摘要

A method implemented in a storage system that has moveable storage devices includes a motion controller receiving movement related data of a storage device from at least one sensor associated with the storage device. The method further includes determining if the received movement related data indicates presence of at least one pre-identified movement related condition that can result in damage to the storage device. In response to the received movement related data indicating at least one pre-identified condition, a park command is issued that triggers the reading head of the storage device to enter a parked state in which the storage device is protected from damage that can occur due to motion of the reading head while the pre-identified condition exists.

1. In a storage system having moveable storage devices, a method comprising:
a motion controller receiving movement related data of a storage device from at least one sensor associated with the storage device; determining if the received movement related data indicates at least one pre-identified condition that can result in damage to the storage device; and in response to the received movement related data indicating at least one pre-identified condition, issuing a park command that triggers the reading head of the storage device to enter a parked state in which the storage device is protected from damage that can occur due to mechanical motion of the reading head while the pre-identified condition exists.
