The scanning step is run for all FSE media in all FSE media pools that are assigned to a specified FSE partition. This step determines the locations of valid and obsolete data on the already closed (full) and still open FSE medium volumes, according to parameters that you define. It then records the scan results to the Resource Management Database (RMDB). The scanning process is performed as a search through the corresponding File System Catalog (FSC), therefore the FSE media themselves are not physically scanned.

The results of the scanning step are used in the copying step. This step copies all selected file generations from the medium volumes being reorganized to open and empty medium volumes in the same FSE media pool. The original volumes are then recycled and finally reinitialized. To reduce the number of drive load and unload operations during the copying step, the data is copied to (open or empty) medium volumes on the same medium, if any exist.

Note that the copying step of the reorganization process is not started until the scanning step has completed, and vice versa.

Before running the copying step, you can review the results of the scan to decide which FSE medium volumes or FSE media you actually want to reorganize. It is only useful to reorganize volumes with a high enough proportion of obsolete data (that is, a high enough percentage of FSE slack space).

During execution of the reorganization process, FSE progressively shows status indicators (such as scanned, in reorg, and recycled) to the medium volumes being reorganized. These indicators help you detect and track the reorganization progress for a particular medium volume. You can display these status indicators at any time with the following command:

fsemedium --list [Barcode] --volume

The following table depicts the reorganization steps, a description of their tasks, the volume status indicators that are set, and the corresponding FSE jobs.

Note that if migrations to a particular FSE medium volume occur after the volume has been scanned but before the copying step has been triggered, the scanned status indicator of this volume is removed. The copying step of the reorganization cannot be started for this volume until the volume is scanned again.

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. 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.
