Deletion policy parameters

Windows specific

You can schedule a task for this purpose.

The progress of the deletion process is logged to the FSE event log, and potential errors are logged to the FSE error log. The list of files that were deleted is written to the HSM file system log file on the FSE client that hosts the FSE partition. The HSM file system log file is called hsmfs_PartitionName.log. The locations of this file is platform-dependent.

Linux specific

HSM file system log file is located in the directory /var/opt/fse/log.

Windows specific

HSM file system log file is located in the directory %InstallPath%\var\log.

The value of %InstallPath% depends on the choice made in the FSE installation process. It defaults to C:\Program Files\Hewlett-Packard\FSE.

You can set up a deletion policy for an FSE partition by specifying appropriate parameters in the FSE partition configuration file. The deletion policy can be set up while configuring a new FSE partition or when modifying an existing FSE partition configuration.

You define a deletion policy with pairs of FileExpiration and Path variables. Each specified FileExpiration variable requires a corresponding Path variable.

File expiration time (FileExpiration)

Definition	A period of time that determines which files in the specified Path directories are to be
	considered for deletion. The following units are available for specifying the time period:
	D (days), M (months), and Y (years).

Impact	This variable determines the files to consider for deletion by checking the period of time
	since each file on the HSM file system was last modified; files modified more than
	FileExpiration time ago are added to the file list.
	If the UNLIMITED value is specified for the FileExpiration variable, the files will
	never be considered for deletion by the FSE deletion jobs. However, you can still delete
	such files manually using operating system utilities.

Directory paths (Path)

Definition	A set of directory paths on the HSM file system on whose files the corresponding file
	expiration period FileExpiration is considered.

Impact	During a deletion job, all files located in the directories specified by the Path variable
	(including all subdirectories), and for which the corresponding expiration period has
	passed, are deleted from the HSM file system.

Notes

When specifying the FileExpiration and Path variables for the deletion policy of an FSE partition, keep in mind the following rules:

•Directory paths are relative to the mount point of the HSM file system (the directory where the HSM file system is mounted).

For example, to specify only the root directory of a particular HSM file system, set Path to / (for HSM file systems located on Linux systems) or \ (for HSM file systems located on Windows systems).

•Directory paths that contain spaces must be enclosed within double quotes (" ").

•A particular directory path cannot be specified more than once.

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.
