Estimating the size of file systems

Table 3 FSE server directory layout

Directory	Contents	File system type	LVM volume

/var/opt/fse/	Configuration Database, Resource	Ext3	required for the
	Management Database, other		FSE backup
	FSE system files

/var/opt/fse/part/	File System Catalogs	Ext3	required for the
			FSE backup

/var/opt/fse/fri/	Fast Recovery Information (FRI)	Ext3	required for the
			FSE backup

/var/opt/fse/diskbuf/FS11	Temporary files of the FSE disk	any	not required
/var/opt/fse/diskbuf/FS2	buffer
...

/var/opt/fse/log/	FSE log files, FSE debug files	any	required for the
			FSE backup

/var/opt/fse/dm/Barcode/	FSE disk media	any	recommended

1.Mount points of file systems assigned to the FSE disk buffer, where /var/opt/fse/diskbuf/ is the root directory of the FSE disk buffer.

NOTE: You can assign additional file systems or volumes to the FSE disk buffer. These file systems must be mounted on subdirectories one level below the root directory of the FSE disk buffer. For details, see the FSE user guide, chapter ”Monitoring and maintaining FSE”, section ”Extending storage space of FSE disk buffer”.

IMPORTANT: To achieve a sufficient stability of the FSE disk media, a separate file system must be dedicated for each disk medium, and it must be mounted to the corresponding subdirectory of the FSE disk media directory. Thus, the FSE disk media directory itself does not need to be located on a separate file system.

Table 4 FSE client directory layout

Directory	Contents	File system type	LVM volume

/var/opt/fse/part/	Hierarchical Storage	Ext3	required
	Management Databases

/var/opt/fse/log/	FSE log files, FSE debug	any	required, if the client is part of
	files		the consolidated FSE system

Each of the previously mentioned file systems holds large databases and/or system files. Therefore, you need to calculate the space requirement for all of them before they are created.

The sizes of the HSM file system, Fast Recovery Information (FRI) files, File System Catalog (FSC), and Hierarchical Storage Manager Database (HSMDB) files are all related to several parameters. Among these parameters are the number of files on an HSM file system and their average size.

By default, 32 MB of journal space is created on Ext3 file systems. This should be sufficient for the file systems of the following directories:

•/var/opt/fse

•/var/opt/fse/part

•/var/opt/fse/diskbuf

14 Introduction and preparation basics

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.
