HP File System Extender (FSE) specs

For details on restarting, see the following content (depending on the platform of a particular FSE host):

•FSE installation guide for Linux, chapter ”Installing FSE software”, section ”Starting the FSE implementation”, subsection ”Restarting FSE processes”.

•FSE installation guide for Windows, chapter ”Installing FSE software”, section ”Starting the FSE implementation”, subsection ”Restarting FSE processes”.

The file systems or volumes added to the FSE disk buffer are automatically detected by FSE and put into use.

Removing a file system from the FSE disk buffer

In general, reducing the storage space assigned to the FSE disk buffer is not advisable. However, there are situations when you need to unassign a particular file system from the FSE disk buffer. This may be required for a major FSE disk buffer reconfiguration task or in case of disaster on the file system because of a disk failure.

CAUTION: If disk failure occurs for a particular file system assigned to the FSE disk buffer, restart the FSE implementation to avoid further data loss. In case of distributed or mixed FSE implementation, make sure to restart the FSE server or consolidated FSE system before restarting external FSE clients.

To remove a particular file system from the FSE disk buffer, proceed as follows:

1.Stop the FSE implementation. In case of distributed or mixed FSE implementation, make sure to stop external FSE clients before stopping the FSE server or consolidated FSE system.

2.On the FSE server or consolidated FSE system, using the operating system utilities, unmount the file system.

3.Remove the mount point of the file system.

4.Start the FSE implementation. In case of distributed or mixed FSE implementation, make sure to start the FSE server or consolidated FSE system before starting external FSE clients.

Checking the consistency of the File System Catalog

Each File System Catalog (FSC) consists of the Data Location Catalog and the Name Space Catalog. It is related to a single FSE partition. Location of the FSC depends on the platform.

Linux specific

FSC is located in the directory /var/opt/fse/part/PartitionName/fsc.

Windows specific

FSC is located in the directory %InstallPath%\var\part\PartitionName\fsc.

The value of %InstallPath% depends on the choice made in the FSE installation process. It defaults to C:\Program Files\Hewlett-Packard\FSE.

Since the File System Catalog functions as a link between files on the HSM file system and their storage positions on media, and contains important data for logical verification of media and for HSM file system recovery, it has to be consistent to enable proper operation of the FSE implementation. HP recommends that you check the consistency of the File System Catalog regularly.

Consistency check of the File System Catalog creates a maintenance job that runs on the specified FSE partition. The consistency check process compares file data stored in the File System Catalog either with actual files on the belonging HSM file system, or with Fast Recovery Information (FRI) on the associated FSE media. All inconsistencies are reported to the FSE check log.

Consistency check of FSC vs. HSM file system

Consistency check of the File System Catalog against the HSM file system matches the files and directories on the HSM file system with the information from the Data Location Catalog and Name Space Catalog, which are parts of the File System Catalog. This process can be executed for the chosen FSE partition. All mismatches in file sizes, file types, attributes, and modification times found during the process are reported to the FSE check log on the FSE client. Location of the log file depends on the platform.

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.
