Capacity disk

Dedicate a disk with high performance for FSE software installation and HSM file systems. Such a disk serves as a primary storage space of files with high frequency of user access, which may affect the performance of the whole FSE implementation. A performance disk is not meant to be a secondary storage space (file archive storage), thus its capacity is not as important as its high performance, which enables optimal operation of FSE.

A capacity disk in the FSE implementation can serve two purposes: to provide storage for FSE disk media or to provide storage for file systems assigned to the FSE disk buffer.

When used for FSE disk media, it should provide large archive storage space in order to store the migrated generations of the files located on the HSM file systems. Frequency of user accesses to these files is relatively low compared to that of the HSM file systems located on the performance disks.

When used for file systems assigned to the FSE disk buffer, it should provide enough storage space to temporarily store files for migrations and recalls.

The available space on disk media in an FSE disk media pool should correlate to the available space on the tape media in the FSE tape media pool assigned to the same FSE partition. The FSE tape media pool is typically used for storing the first copies. Suppose that the tape media pool contains 20 LTO Ultrium 1 media (approximately 20 * 200 GB of available space); the corresponding disk media pool should have 4 TB of available space.

NOTE: HP recommends that a separate file system or volume (disk partition) is assigned to FSE disk buffer to improve robustness and to avoid potential data loss.

If currently allocated storage space for FSE disk buffer is running out, you can extend FSE disk buffer with additional file systems or volumes. For details, see chapter ”Monitoring and maintaining FSE”, section ”Extending storage space of FSE disk buffer” on page 176.

For details on the required file system layout, see the FSE installation guide for a particular platform, chapter ”Introduction and preparation basics”, section ”Organizing the file system layout”.

Local and remote file systems as disk media

FSE supports local file systems to be configured as disk media.

Linux specific

On Linux platform, it is possible to use remote file systems as disk media and to access them via the NFS or CIFS protocol.

NOTE: If you are configuring a remote file system as a disk medium, you can mount only a complete file

system created for this purpose; mounting shared directories (subtree of a file system) is not supported.

Linux specific

On Linux platform, a file system that will be configured as a disk medium must be mounted to a subdirectory of /var/opt/fse/dm, for example:

/var/opt/fse/dm/dm000001

/var/opt/fse/dm/dm000002

Mounting a file system includes adding appropriate file system entries to the /etc/fstab file. For automating the mounting, see the man pages for the fstab and mount commands.

Remote file systems are mounted via the NFS protocol. Note that when using an NFS volume as a disk medium, you must export a file system with the no_squash_root parameter to enable root to access the file system.

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.
