摘要： The invention is a storage device which implements a write barrier command and provides means for a host to designate other write commands as being sensitive or insensitive to the existence of write barrier commands. The device can optimize the execution of commands by changing the order of execution of write commands that are insensitive to write barrier command. In an embodiment of the invention a flag associated with the write command indicates whether the command is sensitive or insensitive to the existence of write barrier commands. In an embodiment of the invention the write barrier command can be implemented as a write command with a flag that indicates whether the command is a write barrier command. In one embodiment of the invention the queue of commands and data to be written to the media is stored in a non-volatile cache.
摘要翻译：本发明是一种实现写入屏障命令的存储设备，并且提供用于主机将其他写入命令指定为对写入障碍命令的存在敏感或不敏感的装置。该设备可以通过改变对写入屏障命令不敏感的写入命令的执行顺序来优化命令的执行。在本发明的实施例中，与写入命令相关联的标志指示命令是否对写入屏障命令的存在敏感或不敏感。在本发明的一个实施例中，写屏障命令可以被实现为具有指示该命令是否是写屏障命令的标志的写入命令。在本发明的一个实施例中，要写入媒体的命令和数据队列被存储在非易失性高速缓存中。

摘要： A data storage device encrypts data stored in non-volatile memory using a bulk encryption key. The data storage device uses a key derivation function to generate an initial encryption key. The data storage device then wraps an intermediate encryption key with the initial encryption key and stores the wrapped intermediate key in the non-volatile memory. The data storage device wraps the bulk encryption key with the intermediate encryption key and stores the wrapped bulk encryption key in the non-volatile memory. The data storage device can unwrap the wrapped intermediate key to generate the intermediate encryption key using the initial encryption key. The data storage device can unwrap the wrapped bulk encryption key to generate the bulk encryption key using the intermediate encryption key. The data storage device decrypts data stored in the non-volatile memory using the bulk encryption key.

摘要： A storage system that stores verify commands for all the write commands requiring verification in a verify-list that will be processed as a background task is described. The verify-list can include coded data fields that flexibly designate selected alternative states or possibilities for how and where the user data is actually stored. Alternatives for the verify-list include storing the actual raw data, no data, the data in compressed form, a CRC type signature of the data and/or a pointer to a backup copy of the data that is stored either in non-volatile memory such as flash memory or on the disk media in a temporary area. In case of a verification error in various alternative embodiments the user data can be recovered using the backup copy in the verify-list in the write cache, the backup copy in flash memory or on the disk, or from the host.
摘要翻译：描述存储系统，其存储将要被处理为后台任务的验证列表中需要验证的所有写入命令的验证命令。验证列表可以包括灵活地指定所选择的备选状态的编码数据字段或用于实际存储用户数据的方式和位置的可能性。验证列表的替代方案包括存储实际原始数据，无数据，压缩形式的数据，数据的CRC类型签名和/或指向存储在非易失性存储器中的数据的备份副本的指针例如闪存或临时区域中的磁盘介质上。在各种替代实施例中的验证错误的情况下，可以使用写入高速缓存中的验证列表中的备份副本，闪存中的备份副本，或者从主机恢复用户数据。

摘要： A method is described for allowing disk drives, such as shingle-written magnetic recording (SMR) drives, to be shipped for customer use with portions of the magnetic media being left untested. The testing is then completed by the drive self-testing in the field. The drive is made functional at the factory by fully testing at least one operational set of regions including an I-region, an E-region and a write cache region. The operational set of regions works as a separate self-contained virtual disk drive and can be used immediately. The remaining untested areas on the media can be tested in the field by a background task and/or when the first write command is received that requires a new track or operational set of regions (on-the fly testing).
