摘要:
Provided are a method, system, and article of manufacture for configuring host settings to specify encryption and a key label referencing a key encrypting key to use to encrypt an encryption key provided to a storage drive to use to encrypt data from the host. User settings are received to configure a data class having data attributes with encryption settings. The data class is stored with the received user encryption settings. A job is received indicating a data set to store to a removable storage medium. A data class is determined having data class attributes matching data attributes of the data set indicated in the job. A determination is made from the determined data class whether to encrypt the data. The data set and a command to encrypt the data set are transmitted to a storage drive in response to determining that the determined data class indicates to encrypt the data, wherein the command to encrypt the data set causes the storage drive to encrypt the data sets written to the removable storage medium with an encryption key.

An apparatus, system, and method are presented for scaling storage media to improve data access performance. A scaling module is provided and configured to receive a dataset, identify storage characteristics of the dataset, make a determination based upon user-defined storage criteria, and select a storage instruction. In one embodiment, the storage instruction is configured to scale the storage medium to a predefined capacity. The predefined capacity of the storage medium is configured to optimize data access performance. Alternatively, the storage instruction is configured to not scale the storage medium. Additionally, the present invention may be configured to map and track the storage medium while the dataset is being written to or read from the storage medium.

The present invention provides fast read performance for accessing a file from a multiplicity of files when its corresponding Block ID is unavailable, by furnishing new file-positioning commands, allowing access to data based on File Number, at the same fast locate speed as with Block Ids, thereby expanding the range of applications that can use certain tape drive systems effectively. The present invention includes both a device architecture for supporting the file oriented positioning and the appending, as well as a software system that can permit easy application access to the device facilities and system components which permit the advantages to accrue without any software application or operator changes, including a robust architecture for navigating residual data, e.g., for data recovery. The present invention comprises several device command innovations, a relative positioning command, an absolute positioning command, and other commands, e.g., for sensing current position.
