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： Enhancements to the functionality of a file system are provided. A file system can provide an additional level of error correction, in addition to the error correction provided by a data storage device. An extension to the metadata area in a file system can store index information about data files that the file system can use to reduce the time it takes to access the files. A file system can use extended metadata to store conditional access information for data files stored in the file system. A data storage device can also examine and characterize the data being stored in order to categorize a user's files automatically. Modules can be loaded into a file system to provide new functionality to the file system. The modules can load additional modules to extend their functionality.

摘要： A system for enhancing command scheduling is provided. In particular embodiments, the system includes a processor and a scheduler that receives commands from the processor for accessing a storage device. The scheduler receives a set of commands, some of which have a deadline, and the scheduler is configured to determine an execution order for those commands. The scheduler is also configured to defer the execution of one or more of those commands to a later time.

摘要： Techniques for optimizing hard disk drive performance. According to one embodiment, a storage system includes a storage unit that stores data and a controller. The controller receives an idle mode indication and performs at least one operation based on the idle mode indication. According to another embodiment, a host system includes a processor and a scheduler that is operative to issues commands. The processor computes the idle mode indication, and the processor sends the idle mode indication to the storage system.
