摘要： A disk storage device stores write data in a cache area of a data buffer according to a write command from a host, reports write completion to the host, and then writes the write data in the cache area to a storage medium. The disk storage device stores the write data stored in the data buffer in a save area created on the storage disk in response to the reception of a command which requires integrity, other than a write command, and reports a response to the host. Therefore processing time of this command and response time to the host can be decreased, while maintaining the safety of the write data.
摘要翻译：磁盘存储装置根据来自主机的写入命令将写入数据存储在数据缓存器的高速缓存区域中，向主机报告写入完成，然后将写入数据写入高速缓存区域到存储介质。磁盘存储装置将存储在数据缓冲器中的写入数据存储在存储盘上创建的存储区域中，以响应于除了写入命令之外的需要完整性的命令的接收，并且向主机报告响应。因此，可以在保持写入数据的安全性的同时减少该命令的处理时间和对主机的响应时间。

摘要： According to one embodiment, a storage apparatus includes: an encryption key generation information generator configured to generate encryption key generation information used to generate an encryption key based on information from a host computer; an encryption key generator configured to generate the encryption key based on the encryption key generation information; an initialization data encryption module configured to encrypt initialization data of a storage medium received from the host computer using the encryption key; a decryption module configured to decrypt data read from the storage medium using a decryption key corresponding to the encryption key; a comparator configured to compare data decrypted by the decryption module and the initialization data; and a write processor configured to permit, when the comparator determines that the data decrypted by the decryption module and the initialization data match with each other, to write user data in the storage medium.

摘要： 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.
