MAM

See ”Medium Auxiliary Memory (MAM)”.

Management

An add-on to the basic FSE product that provides graphical user interface for most of the

Console (MC)

configuration, operation, monitoring, and management tasks in the FSE implementation.

 

Management Console consists of two separate modules: Management Console server and

 

Management Console client.

Management

An FSE daemon (service), responsible for accepting, handling, and executing requests for user

Interface (MIF)

actions, issued through the FSE command-line interface. It also starts and manages execution of

 

the administrative jobs. The Management Interface process name is fse-mif.

media duplication

A process that creates an exact copy of an FSE tape medium. In case of emergency, a medium

 

duplicate can directly replace the original.

media pool

A common storage for the migrated HSM file system data. It groups FSE media of the same

(FSE media pool)

type into a logical unit, which is tracked as a group. FSE media inside the same FSE media

 

pool share such characteristics as number of medium volumes (tape partitions), system volume

 

feature, capacity of medium volumes, and so on. Media pool types are: regular, WORM, and

 

backup. Each FSE partition needs at least one regular FSE media pool assigned to it. The same

 

media pool cannot be assigned to multiple partitions.

medium

A high-capacity magnetic tape, or a disk medium used by the FSE implementation. FSE medium

(FSE medium)

volumes are stored on tape partitions, in case of tape medium, or in file system subdirectories,

 

in case of disk medium. Tape medium is further divided into tape partitions and disk medium is

 

divided into subdirectories. Tape partitions store FSE medium volumes on a tape medium and

 

subdirectories store FSE medium volumes on a disk medium. FSE media represent the

 

secondary storage space in an FSE implementation. See also ”disk medium (FSE disk

 

medium)”.

Medium Auxiliary

A memory chip integrated into magnetic tapes of the LTO Ultrium family, designed to improve

Memory (MAM)

tape performance. FSE uses Medium Auxiliary Memory in LTO Ultrium and LTO Ultrium WORM

 

medium to store information about the medium, its volumes, current position of the tape, and so

 

on, thus reducing the access time when searching for requested data on the medium.

medium volume A physical partition on an FSE medium, with its own volume header. There are two types of (FSE medium volume) medium volumes: data volume and system volume. Data volumes store migrated file data, while

system volumes store redundant copies of Fast Recovery Information from all data volumes on the medium. LTO media can have a single data volume and no system volume.

migration candidate An online, dirty file that is scheduled for migration.

migration candidate A list of files that were changed and have passed a certain period of time defined by the

listmigration policy, which are waiting for migration. The list is maintained by the Hierarchical Storage Manager.

migration policy

A set of rules by which the migration jobs for files on an HSM file system are initiated.

 

Configuration parameters for the respective policy are specified in the FSE partition

 

configuration file. Each FSE partition has its own migration policy.

migration retention

A period of time during which a migrated file is kept online before it is released. See also

time

”retention time”.

migration, migration A process, executed by the Partition Manager, that copies the file contents from the HSM file

jobsystem to the FSE media. When the process is completed, the file entries of the migrated files are moved from the migration candidate list to the release candidate list.

Name Space Catalog A part of the File System Catalog. NSC includes metadata of files on an HSM file system, such

(NSC)as directory structure, standard attributes, ownership (on Linux platform), and ACL (Access Control List) and Alternate Data Streams (on Windows platform). This metadata enables recovery of an HSM file system. See also ”File System Catalog (FSC)”.

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.
