recall, recall job

A process, executed by the Partition Manager, that copies the file contents from the FSE media

 

to the HSM file system. Once the process is completed, the offline file becomes online again. Its

 

file entry is then added to the release candidate list.

recovery

A process, executed by the Partition Manager, that recovers the HSM file system or the File

(FSE recovery)

System Catalog (FSC) without requiring FSE backup copies. The HSM file system is recreated

 

from the Name Space Catalog (NSC), while the FSC is recreated either from Fast Recovery

 

Information (FRI) or from migrated metadata. FSE recovery can be used as a fallback if restore

 

of FSE is not possible due to missing FSE backup data. A recovery job is triggered explicitly on

 

an FSE user's request with the fserecover command.

recovery job

See ”recovery (FSE recovery)”.

recycled medium

An FSE medium volume from which all selected data was copied to another medium volume

volume

during media reorganization. The data on recycled medium volumes can no longer be

 

retrieved, but the storage space on such volumes can be reused for new migrated data.

redundant data copy A process in FSE that recreates a copy of a file set that has become unreadable, most probably

recreation because the FSE medium to which it was migrated is damaged. The process recreates the damaged data copy using copies of the same data that were migrated to other FSE media pools. Therefore, the main prerequisite to execute this process is a multiple media pool configuration of the corresponding FSE partition. A redundant data copy recreation process is triggered manually by the FSE administrator.

regular release

Release of files on an HSM file system that are on the release candidate list and meet the

 

predefined criteria, triggered when the high watermark of usage is reached on the HSM file

 

system. The process is stopped when the low watermark on the HSM file system is reached. See

 

also ”release”.

release

A process that usually follows a migration or recall, executed by the Hierarchical Storage

 

Manager. This process removes the file data from the HSM file system, leaving only the file

 

header. Release is triggered by the Partition Manager according to the defined watermarks.

 

After release, files are offline and their file entries are removed from the release candidate list.

release candidate

An online file that is scheduled for release and that has either been migrated or was brought

 

online by recall.

release candidate list A list of online files that have already been migrated or that have recently been recalled and are waiting to be released. The list is maintained by the Hierarchical Storage Manager.

release policy

A set of rules by which the release process for files on a release candidate list is initiated.

 

Configuration parameters for the release policy are specified in the FSE partition configuration

 

file. Each FSE partition has its own release policy.

resource

Either an FSE partition, FSE library, FSE drive, FSE media pool, or FSE medium including

(FSE resource)

medium volumes. Each FSE resource is configured using an FSE configuration file and has an

 

entry in the Resource Management Database.

Resource

A database with records of all configured FSE resources. It contains all relevant resource

Management

information, such as configuration parameters, resource characteristics, current status, usage

Database (RMDB)

statistics, and relations to other resources. The Resource Management Database is located in

 

the directory /var/opt/fse/rmdb (on Linux platform) or in the directory

 

%InstallPath%\var\rmdb directory (on Windows platform).

Resource Manager

An FSE daemon (service) responsible for managing data in the Resource Management

(RM)

Database, allocating and releasing FSE resources and providing resource information to other

 

FSE daemons (services) and processes. The Resource Manager process name is fse-rm.

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.
