InputFile, Utf8 | HP File System Extender (FSE) specs

2.6 NAME

is recalled in one recall job, thus reducing recall job overhead and unneces- sary rewinds of tape media.

Successfully recalled ﬁles are logged into the HSM ﬁle system log ﬁle, hsmfs_<PartitionName>.log. Files that failed to be recalled are logged into the FSE error log ﬁle, error.log, with a single failure indicator in the FSE event log ﬁle, fse.log. For location of log ﬁles, see section FILES in the fseintro man page.

You can further increase performance of the recall jobs triggered with the – – if option by specifying the parameter SeekThreshold in the ﬁle drive.cfg. For description of drive.cfg and its location, see section FILES in the fseintro man page. The value of SeekThreshold affects the Back End Agent behavior when recalling several ﬁles in one recall job. If the difference in locations of two ﬁles on the medium is greater than SeekThreshold, the Back End Agent seeks to the position of the latter, rather than "reading" through the gap on the medium. If the parameter is not deﬁned or drive.cfg does not exist, a default value is used, depending on the type of media from which data is recalled. With tape media, SeekThreshold defaults to 5% of the medium size. With disk media, SeekThreshold always defaults to disk block size. This option can only be used in combination with the – –recalloption.

•InputFile

File name (with optional path) of the ﬁle that contains list of ﬁles to be recalled using the efﬁcient recall functionality. In InputFile each ﬁle must be speciﬁed on a separate line. For every ﬁle, you can provide either only its ﬁle name or you can precede the ﬁle name with a corresponding path relative to the mount point directory. If InputFile is not speciﬁed, the standard input is used as a source for ﬁle list.

Note:

Due to an underlying omniORB/CORBA limitation, the upper limit on the ﬁle list size is 26000 entries.

•–8 ,– –utf8

Specify that the contents of the ﬁle InputFile (if InputFile is speciﬁed with the – –ifoption) or the standard input (if InputFile is not speciﬁed) are in the UTF–8 format. This option can only be used in combination with the

– –ifoption.

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.
