HP File System Extender (FSE) instruction

Total	Total amount of space on the FSE media assigned to the media pool.
SlackSpace	Amount of FSE slack space (in percentage).
	FSE slack space is the space on FSE media occupied by migrated file generations
	considered obsolete (not valid) by the reorganizational scan job.

Displaying the FSE media-based statistics

To check the statistics for all FSE media that belong to a particular FSE partition:

1.Ensure that the scan job running on the chosen partition has completed.

2.Run the command:

fsepartition --reorg-statPartitionName [SlackThreshold%]

You can also specify a value for the optional SlackThreshold% argument to filter out media for which the percentage of obsolete data is not high enough, and thus less likely to need reorganizing.

Example command output:

Barcode VolNum ValidData[MB] Total[MB] SlackSpace[%]

Med001	6	980	1200	19%
Med002	5	190	1000	81%
Med003	5	0	1000	100%
Med004	5	100	1000	90%

The meaning of the columns is the following:

VolNum	Number of the FSE medium volumes on the medium.
ValidData	Amount of space on the FSE medium occupied by valid file generations.
	If the FSE medium has not yet been scanned for reorganization, it has 0 (zero)
	displayed in place of the ValidData amount.
Total	Total amount of space on the FSE medium.
SlackSpace	Percentage of FSE slack space.
	FSE slack space is the space on the medium occupied by migrated file generations
	that were considered obsolete by the reorganizational scan job.

Running the media reorganization job

Using the fsemedium command, you can run the copying step of the reorganization process on all medium volumes of a specific medium, on a single FSE medium volume, or on a series of specified FSE medium volumes.

By default, the command reports the progress of the reorganization monitoring purposes. You can disable monitoring by specifying the

job to the command shell for --no-monitoroption.

NOTE: To prevent the copying step of the FSE reorganization job from copying the data to the same medium (that is, to the medium whose medium volumes are being reorganized), set the condition status of the medium being reorganized to unreliable before running the reorganization job. Use the fsemedium --mark-unreliablecommand for this purpose.

Note that FSE media with the condition status unreliable are not available for migrations. After the reorganization job has finished, and the reorganized medium volumes have been reinitialized, you must remove the unreliable status of the reorganized medium using the fsemedium --mark-goodcommand.

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.
