NOTE: WORM media can only be formatted once.

A medium is formatted using the following command:

fsemedium --format Barcode

If particular medium has already been used in the FSE implementation or contains certain types of data, you must use forced formatting to format it. This is possible only with non-WORM media. The following command initiates forced formatting for a medium:

fsemedium --format Barcode --force

For more information on the fsemedium command, see the FSE CLI reference.

The following table helps you determine what kind of formatting is allowed for different kind of media that are identified by FSE.

Skipping media formatting

In certain cases, a medium only needs to be initialized in order to be used in the FSE implementation, and the formatting step can be skipped. This can be done for the following media:

•new or already used LTO Ultrium media

These media support only one medium volume and do not need partitioning.

•other media that have been used in the FSE implementation, if the layout of medium volumes on the medium will not change.

The layout includes the number of data volumes and the presence and position of the system volume on the medium. For details, see ”FSE medium volumes” on page 98.

Once the medium is formatted, it becomes an FSE medium, and you need to initialize the medium volumes on it.

Initializing media

After formatting, an FSE medium needs to be initialized. Initialization is the second step of the media preparation for use in the FSE implementation. For each medium volume on the FSE medium, initialization labels its header and adds a corresponding medium volume entry to the Resource Management Database.

A medium is initialized using the following command:

fsemedium --init Barcode

If particular medium has already been used in the FSE implementation or contains certain types of data, you must use forced initialization to initialize it. The following command initiates forced initialization for a medium:

fsemedium --init Barcode --force

By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
