enables multiple copying of migrated files, thus satisfying the need for additional backup copies and avoiding recall failures.

Library - tape compatibility

FSE software is a part of HP StorageWorks File System Extender, and can be used with supported SCSI tape libraries with supported drive types.

FSE software supports LTO drive technologies for LTO Ultrium 1, LTO Ultrium 2, and LTO Ultrium 3 media. LTO Ultrium 3 WORM media are supported where a WORM type tape media is required.

With LTO drives and media, FSE software also supports special memory chips, called Medium Auxiliary Memory (MAM), which are integrated in the LTO Ultrium tape cartridges and enable LTO Ultrium drives to locate files much faster.

For a list of the supported tape libraries, tape drives, and tape media, see the latest support matrices.

Automatic error detection

FSE automatically detects drive and media hardware errors. When FSE detects such errors, the following happens:

•The drive status is set to error.

•If an error occurs during a migration job, the medium status is set to unreliable, which disables further writing to it.

•If an error occurs during a recall job, the medium status is set to unusable, which disables reading from and writing to it. Neither the drive nor the medium in it are used for the operation until the administrator appropriately changes the drive and medium statuses. For more information, see ”Changing the condition status of media” on page 119.

In each of the above cases, an appropriate entry is written to the FSE event log. If you find an FSE medium marked unreliable or unusable, the FSE event log and FSE error log need to be searched backwards to identify the root cause of the problem.

For more information about FSE log files, see chapter ”Monitoring and maintaining FSE”, section ”FSE log files” on page 196.

Automatic detection of low storage space

If the HSM Health Monitor (HHM) utility is installed and configured, FSE can automatically detect low storage space related conditions such as:

•low disk space on file systems with FSE databases and system files

•low disk space on HSM file systems

•low secondary storage space

If any of the above conditions occurs, an e-mail can be sent and a configurable action can be triggered. Likewise, when the condition is not present anymore, an e-mail can also be sent and a configurable action can be triggered.

Typical actions that may be triggered involve putting the monitored HSM file systems into Limited Access Mode, notifying the FSE users, shutting down the FSE system in case of unrecoverable situations, or putting the monitored HSM file system online again in case the condition is no longer present.

For more information on automatic low storage detection, see chapter ”Monitoring and maintaining FSE”, section ”Low storage space detection” on page 186.

NFS and CIFS support

Remote Linux and Windows clients access HSM file systems using standard protocols. Network File System (NFS) is the standard protocol for UNIX and Linux platforms. Common Internet File System (CIFS) is the standard protocol for Windows platform.

Linux FSE system specific

FSE supports access to FSE partitions from remote locations via NFS and CIFS protocols.

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.
