Storage space for FSE debug files

•Total storage space on file systems or volumes that are assigned to FSE disk buffer should be at least 10% of total storage space on all HSM files systems in the FSE implementation.

•Each file system or volume assigned to FSE disk buffer should be at least twice as large as the largest file that will be put under FSE control.

Additionally, if you plan to perform a duplication of FSE media, the following prerequisite must be fulfilled:

•At least one of the file systems or volumes assigned to FSE disk buffer should be at least twice as large as the total storage space on the largest FSE medium.

For example, to enable duplication of a 100 GB medium, each file system or volume assigned to the FSE disk buffer should have at least 200 GB of storage space.

The /var/opt/fse/log/debug directory holds optional FSE debug files. These files contain large amount of data and can grow very fast. In order to prevent them filling up the /var/opt/fse file system, you need to make the directory /var/opt/fse/log/debug a symbolic link to a directory outside the file system for /var/opt/fse. For example, you can make the symbolic link point to one of the following directories:

•/var/log/FSEDEBUG

•/tmp/FSEDEBUG

The directory /tmp can be used only if it provides large storage space and is not part of the root file system, that is: if a separate file system is mounted to /tmp.

Creating symbolic links is done after you create and mount the required file systems.

NOTE: If there is enough disk space that is not yet partitioned, you can also make a new partition for the debugs, create an Ext3 file system on it, and mount it on /var/opt/fse/log/debug.

You need to add a line to the /etc/fstab file, for example

/dev/mynewdebugpart /var/opt/fse/log/debug ext3 defaults 1 2

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.
