For further information on the recall process and its configuration, see chapter ”Migration, release, recall, and deletion” on page 123.

Deletion

Deletion is a process of obsoleting and removing obsolete files from HSM file systems. You can use this process for various purposes, including Information Lifecycle Management (ILM) and freeing disk space of redundant files.

The criteria that induce file obsolescence on HSM file systems are defined in the deletion policy. Each HSM file system has its own deletion policy. Deletion is enabled on regular and WORM HSM file systems.

For further information on deletion process and its configuration, see chapter ”Migration, release, recall, and deletion” on page 123.

FSE components

HSM file system

An HSM file system (HSM FS) is a hard disk area reserved for storage of user files and directories (user data), and managed by the FSE implementation. The HSM file system is used to store the metadata (names, attributes, and permissions of user data) and user data that is currently online.

Linux specific

On Linux platform, HSM file system is based on the Ext3 file system; the HSM attributes are stored in Ext3 extended attributes.

Windows specific

On Windows platform, HSM file system is based on the NTFS.

In an FSE installation, an HSM file system represents the primary storage space, and the FSE media represent the secondary storage space.

An HSM file system can be configured either as a regular file system or as a WORM file system:

•Regular file system

All files and directory operations are supported as known for the native file system of the respective platform.

•WORM (Write-Once Read-Many) file system

File and directory operations are restricted to read-only after a configured period of time. The limitation does not include adding files to directories, which can be done in the same way as on a regular file system.

For details on configuring a WORM HSM file system, see ”Phase 4: configuring FSE partitions” on page 73.

Hierarchical Storage Manager (HSM) is a component of the HSM file system. As a part of an FSE client, it handles HSM file system events and manages the migration and release candidate lists. Each mounted HSM file system has one FSE HSM.

In a distributed FSE implementation, the HSM file systems, their Hierarchical Storage Managers (HSMs), and the File System Event Manager are located on external FSE clients.

FSE partition

FSE uses FSE partitions to split the storage into multiple entities, meaning that one FSE implementation can have more than one FSE partition. This way FSE provides the possibility for a complex organization of data management.

Each FSE partition is related to a single HSM file system and has its own policies and its own File System Catalog (FSC). This enables you to configure individual policies (migration, release, deletion, and resource allocation) for a particular FSE partition, according to the characteristics of files and their intended use.

Each configured FSE partition is controlled by one Partition Manager (PM), which creates and manages FSE jobs for migration, recall, and deletion operations. The Partition Manager is located on the FSE server. It is included in the FSE server installation package.

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.
