Job, FSE job | HP File System Extender (FSE) specification

HSM file system A file system, controlled by the FSE software. It is used to store file metadata (name, attributes,

(HSM FS)permissions) and online files of an FSE partition. HSM file systems represent the primary storage space of an FSE implementation. On the Linux platform, HSM file systems are based on the Linux native Ext3 file system and FSE specific attributes are stored as Ext3 extended attributes. On the Windows platform, HSM file systems are based on the Windows native NTFS file system.

HSM file system filter The function of this module is to intercept relevant file system events for the FSE implementation and to report them to the Hierarchical Storage Manager. On Linux platform, the filter is a kernel module providing the HSM file system that is built on top of the Linux native Ext3 file system and HP OnlineJFS/JFS 3.5, respectively. On Windows platform, the filter is a kernel driver and intercepts all accesses to the Windows native NTFS file system.

HSM Health Monitor A utility for monitoring storage capacity on file systems with FSE databases and system files, on

(HHM)HSM file systems, and on the secondary storage space assigned to HSM file systems. The utility can be configured to trigger actions if storage capacity rises above or drops below configurable thresholds.

implementation HP StorageWorks File System Extender. Hardware with installed FSE software. FSE hardware (FSE implementation) includes a tape library with drives, slots, media, and a changer, which is connected to the FSE

server host machine via an SCSI interface. See also ”software (FSE software)”.

initialization	A process that labels the medium volume header on each volume found on a medium and
	adds the corresponding FSE medium volume entry to the Resource Management Database. If
	an FSE medium or FSE medium volume contains valid FSE user data and you want to initialize
	it, you must use forced initialization.
job	A process, executed by Partition Manager or Management Interface, which executes migration,
(FSE job)	recall, reorganization, administrative, backup, recovery, and maintenance tasks. Migration and
	recall jobs are triggered automatically by their respective policy, whereas reorganization,
	administrative, backup, recovery, and maintenance jobs are triggered with FSE commands.
library	A SCSI tape library attached to and configured for use in the FSE implementation.
(FSE library)

Library Agent (LA) An FSE agent that handles requests for moving the FSE media between tape drives and library slots and triggers media barcode rescans. The Library Agent process name is fse-la-s.

Limited Access Mode One of the two HSM file system filter operational modes. When the HSM file system filter is

(LAM)operating in Limited Access Mode for a particular HSM file system, you are only allowed to browse the directory tree on the HSM file system or read the online data from it. You cannot create, rename, move or delete directories and files, nor change their data or metadata.

Offline data is not recalled from FSE media; instead, the application that is accessing the file receives an error. Limited Access Mode does not need FSE processes to be running on the FSE client. However, if the processes are running, three data movement processes (migration, release, deletion) can be executed – by being either triggered explicitly or started according to the configured FSE partition policies. See also ”Full Access Mode (FAM)”.

Log Analyzer (LA)	A utility for monitoring FSE event log files, which can be configured to periodically analyze
	these files for specific patterns and send notification e-mails or SNMP traps.
low watermark	A user-defined value for a level of disk usage on an HSM file system. When this value is
	reached, a regular release process is stopped.
LTO Ultrium	A Linear Tape-Open (LTO) tape format and tape drive product family from IBM and HP. FSE
	supports LTO Ultrium 1, 2, 3, and LTO Ultrium 3 WORM series of tape media, and LTO Ultrium
	1, 2, 3, and LTO Ultrium 3 WORM series of tape drives. See also ”medium (FSE medium)”.
maintenance job	One of the FSE job types that performs maintenance tasks in FSE, namely, the File System
	Catalog (FSC) consistency check and recreation of redundant migrated data copies.

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.
