tool

A command that communicates directly with FSE daemons (services) and agents besides

(FSE tool)

Management Interface, designed for low-level modifications and more extensive monitoring

 

and troubleshooting tasks. FSE tools are only intended for use by experienced FSE users

 

(typically on request of technical support personnel of FSE). Note that incorrect use of FSE tools

 

can cause data corruption. FSE tools are located in the directory /opt/fse/sbin/tools (on

 

Linux platform) or in the directory %InstallPath%\bin (on Windows platform).

Ultrium

See ”LTO Ultrium”.

unreliable medium

An FSE medium to which further writing is disabled, but from which FSE is still able to read

 

data. As soon as the first write error is detected while the Back End Agent is writing data to the

 

medium, the medium is automatically marked as unreliable in the Resource Management

 

Database. Such errors usually occur because of an excessive use of the medium.

unusable medium

An FSE medium which has been disabled for both writing to and reading from. As soon as the

 

first read error is detected while the Back End Agent is reading data from the medium, the

 

medium is automatically marked as unusable in the Resource Management Database. Such

 

errors usually occur because of an extremely excessive use of the medium.

user

A computer system user who uses one or more HSM file systems for managing data.

(FSE user)

 

utility

An add-on FSE component that provides additional functionality and complements basic FSE

(FSE utility)

components. In current FSE release, two FSE utilities are part of the FSE software: HSM Health

 

Monitor and Log Analyzer. See also ”HSM Health Monitor (HHM)”, ”Log Analyzer (LA)”.

verified drive

An FSE drive that is put back in operation after its problems have been resolved. This is done

 

by changing its status in the Resource Management Database to online. The online status

 

is set by enabling the drive with the fsedrive command.

WORM file system

A file system on which a file can be written only once, but can be read many times. A WORM

 

(Write Once Read Many) file system prevents both files and their metadata from being

 

modified, regardless of their access permissions. Consequently, it is not possible to remove files

 

from directories or rename them; it is only possible to add new files (as on a regular file

 

system). Files and directory operations are restricted to read-only after a period of time. A

 

WORM partition must be related to WORM media pools containing WORM media only.

WORM medium

On a WORM (Write Once Read Many) medium, data can be recorded only once. Once

 

recorded, the WORM medium cannot be overwritten, reformatted, or reinitialized, but new

 

data can be appended to the existing contents. A WORM medium can only be initialized in a

 

WORM media pool.

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.
