FSE media types, Disk media | HP File System Extender (FSE) guide

Volumes of this type cannot be created on the supported LTO Ultrium media and are not used on disk media.

FSE supports up to 255 volumes on disk media. Other specifics of different media types are described in the next section.

FSE media types

The following is a list of the supported media types and their characteristics:

•LTO Ultrium 1, LTO Ultrium 2, LTO Ultrium 3 Used in regular and backup media pools.

LTO Ultrium media do not support multiple volumes and do not need to be formatted. A single data volume is created on such media during initialization.

Media that belong to the backup FSE media pool should be configured with only one volume. For details on backup media, see ”Backup media management” on page 223.

•LTO Ultrium 3 WORM

Used in WORM media pools only.

Once recorded, WORM media cannot be overwritten, re-formatted, or re-initialized, but new data can be appended to the existing contents. Note that the FSE prevents WORM media from being initialized in a non-WORM media pool.

•Disk media

Used in regular media pools only.

Disk media are implemented as storage space in a directory on the consolidated FSE system or FSE server. This storage space must consist of multiple file systems, with one file system used for each disk medium. Each file system is mounted to a separate subdirectory. On Linux platform, for example, two disk media are represented as /var/opt/fse/dm/dm000001 and

/var/opt/fse/dm/dm000002. Instead of barcode, the last part of path (dm000001, dm000002) is used for identification. You should use an appropriate naming convention which will prevent disk media from being misidentified as tape media.

Linux specific

On Linux platform, disk media are located in the directory /var/opt/fse/dm. Windows specific

On Windows platform, disk media are located in the directory %InstallPath%\var\dm.

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

A file system for disk media can be either local or remote. For more information, see ”Disk media” on page 99.

Disk media

An FSE disk medium is a mounted file system that emulates an FSE tape medium; therefore, managing disk media is similar to managing tape media. Using FSE disk media is advantageous in terms of recall, since it significantly decreases the time required to bring files back online (offline file access times).

When an FSE user requests an offline file, a recall job first attempts to allocate a medium from the FSE disk media pool and only if no such medium exists it allocates a tape medium. When offline files are located on a disk medium, recalls can run simultaneously and are not affected by the number of currently unallocated drives, but by the corresponding FSE partition configuration parameters. No more than MaxNumDrivesRecall x 2 jobs can be started at once. The MaxNumDrivesRecall and other configurable FSE partition parameters are described in ”Partition allocation and job priority policy” on page 144.

Before starting to use disk media, you should consider the following points about the two types of disk in an FSE implementation:

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.
