Reorganizing media

In FSE, data stored on an HSM file system is automatically and periodically migrated to FSE media. This applies not only to every new file created on the HSM file system, but also to every existing file whose attributes or contents is modified. Each modification of the file subsequently causes it to be migrated to media as a new file generation.

Over time, the situation can arise where a large proportion of space on FSE media is occupied by old, obsolete generations of files. FSE enables you to reclaim media space by reorganizing the data on the media. The media reorganization process frees space on media by preserving only selected file generations and removing the others. FSE media space can then be reused for newly migrated data.

NOTE: LTO Ultrium 3 WORM media cannot be rewritten or reformatted, but they can be reorganized. However, the media space reclaimed cannot be reused.

Although you cannot reuse WORM media space, the reorganization of WORM media is necessary when you need to destroy sensitive data that was migrated to these media, while preserving the rest of the data. In these circumstances, the last step of the data erasure process is the physical destruction of the WORM media that hold the sensitive data.

Media reorganization is a medium-volume-based process. This means that the smallest unit of the secondary storage space that can be reorganized is a single FSE medium volume. Similarly, the smallest unit that can be reused is an FSE medium volume. As system volumes do not contain file data, only data volumes can be reorganized.

Prerequisites

•Before scanning media as part of the media reorganization process run the FSC vs. media check with the --autocorrectand --match-mediaoptions. For more information, see ”Consistency check of FSC vs. FSE media” on page 182.

Limitation

•After the reorganization of one or more FSE medium volumes on an FSE medium, any duplicates of the medium created before the reorganization are rendered useless, as (part of) the source medium has been reinitialized at the end of the reorganization job.

To restore data safety level, you need to duplicate each medium that contains reorganized medium volumes and whose sources for the reorganization process were duplicated before the reorganization.

The media reorganization process

The media reorganization process consists of two steps: scanning and copying. Each step is controlled and performed by its own FSE job.

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.
