General recommendations

Keeping the FSC and HSMDB journals small

The journals of File System Catalog (FSC) and Hierarchical Storage Manager (HSMDB) can grow quite large with daily FSE usage. However, they are truncated every time the FSE implementation is backed up successfully. By backing up the FSE implementation regularly, the size of the journals remains acceptable.

Linux specific

FSC journals are located on the system that hosts an integrated FSE system or an FSE server in the directory

/var/opt/fse/part/PartitionName/fsc/journal

HSM journals are located on the system that hosts an integrated FSE system or an FSE client in the directory

/var/opt/fse/part/PartitionName/hsm/journal

Windows specific

FSC journals are located on the system that hosts an integrated FSE system or an FSE server in the directory

%InstallPath%\var\part\PartitionName\fsc\journal

HSM journals are located on the system that hosts an integrated FSE system or an FSE client in the directory

%InstallPath%\var\part\PartitionName\hsm\journal

Handling old FSE log, debug and disk buffer files

If tracing of the FSE implementation is enabled, FSE log and debug files can grow quite big through daily FSE use. The FSE disk buffer files can also occupy a significant amount of disk space if they are accidentally left on disk.

Linux specific

To prevent the disk from being filled up, HP recommends that you execute the fse_cleantmp.sh script regularly. Use the crontab command to schedule the script.

fse_cleantmp.sh performs two different tasks:

It archives FSE log and debug files older than the defined number of days set for the archiving task.

It deletes archives older than the defined number of days set for the removal task. Originals of the archived files are always deleted unless they are currently used by an FSE process or are meant to be used later. FSE disk buffer files are handled in the same manner.

Windows specific

If you are concerned with excessive growth of FSE debug files, consider allocating a dedicated disk partition/volume to a file system, which can then be mounted to %InstallPath%\var\log\debug.

Shortening the termination delay for FSE commands

FSE uses CORBA technology and its omniORB implementation for its internal interprocess communication. omniORB also prepares and initializes the environment in which FSE processes is run, and cleans up the environment after the processes are terminated. This takes time.

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.
