US 2006/0215307 A1 · Storage apparatus, control method and program

Abstract

The write cache control unit stores data in the buffer memory in response to a write command from a higher-level apparatus to respond a normal ending of the command, and then writes the data in the buffer memory on the disk medium. The vibratory environment measuring unit measures an environment under which a vibration is applied to the apparatus. When an abnormal vibratory environment under which writing on the disk medium likely fails is determined from a measured environment by the vibratory environment measuring unit, the vibration countermeasure processing unit disables the write cache control unit, and if the write cache data remains in the buffer memory at that time, writes the data in the temporary storage area, and if the abnormal vibratory environment is not determined, writes back the data to the original position on the disk medium.

Dependent claims

A storage apparatus for writing data on a storage medium based on a write command from a higher-level apparatus, comprising:

a write cache control unit for storing data in a buffer in response to a write command from the higher-level apparatus to respond a normal ending of the command, and then writing the data in the buffer on the storage medium;
a vibratory environment measuring unit for measuring a vibratory environment of the apparatus;
and
a vibration countermeasure processing unit for, when an abnormal vibratory environment under which writing on the storage medium likely fails is determined from a measured vibratory environment by the vibratory environment measuring unit, disabling the write cache control unit.

A method for controlling a storage apparatus for writing data on a storage medium based on a write command from a higher-level apparatus, comprising:

a write cache control step for storing data in a buffer in response to a write command from the higher-level apparatus to respond a normal ending of the command, and then writing the data in the buffer on the storage medium;
a vibratory environment measuring step for measuring a vibratory environment of the apparatus;
and
a vibration countermeasure processing step for, when an abnormal vibratory environment under which writing on the storage medium likely fails is determined from a measured vibratory environment by the vibratory environment measuring step, disabling the write cache control step.

1 more element

A program for writing data on a storage medium based on a write command from a higher-level apparatus, wherein said program allows a computer to execute:

a write cache control step for storing data in a buffer in response to a write command from the higher-level apparatus to respond a normal ending of the command, and then writing the data in the buffer on the storage medium;
a vibratory environment measuring step for measuring a vibratory environment of the apparatus;
and
a vibration countermeasure processing step for, when an abnormal vibratory environment under which writing on the storage medium likely fails is determined from a measured vibratory environment by the vibratory environment measuring step, disabling the write cache control step.
