Reconfiguration procedure | HP File System Extender (FSE) guide

The initial configuration must be performed after the FSE software package installation, before the FSE implementation is put into operation for the first time. Afterwards, if the implementation or the network type is changed, the communication settings must be reconfigured.

CAUTION: An appropriate configuration of the FSE interprocess communication is of crucial importance for normal FSE operation. Incorrectly configured interprocess communication may lead to a non-operating FSE implementation.

FSE interprocess communication settings consist of two plain text files installed on each FSE host. The files and their locations are the following:

Configuration file	Location on Linux platform	Location on Windows platform

services.cfg	/etc/opt/fse	%InstallPath%\etc

omniORB.cfg	/etc/opt/fse	%InstallPath%\etc

NOTE: Depending on the network type used for interprocess communication in your FSE implementation (ordinary LAN, private network), omniORB.cfg may not be present in the specified directory. You can always find its template in the directory /opt/fse/newconfig (on Linux systems) or %InstallPath%\newconfig (on Windows systems) and copy the file to its target location, if needed.

You can also change the default path where FSE searches for the omniORB.cfg file using the OMNIORB_CONFIG environment variable.

The reconfiguration procedure

The general procedure for reconfiguring interprocess communication is as follows:

1.Stop all FSE processes with the fse --stopcommand.

Note that you must first stop the processes on external FSE clients, and then stop the processes on a consolidated FSE system or on the FSE server.

2.Stop the omniNames service with the omniNames --stopcommand.

3.Purge the omniNames (CORBA) service data files. Their location is platform-dependent. Linux specific

On Linux platform, omniNames service data files are located in the directory

/var/opt/fse/omniorb. Windows specific

On Windows platform, omniNames service data files are located in the directory

%InstallPath%\var\omniorb.

4.Modify the services.cfg or omniORB.cfg file on all FSE hosts according to the changes in your FSE implementation or changes of the network type employed. The required modifications are described in the following sections.

You can use the FSE proprietary fse_net tool to retrieve the parameters required for the configuration. For more information on fse_net, see ”FSE troubleshooting tools” on page 274.

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.
