HP File System Extender (FSE) manual Linux-specific recommendations

Page 17

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

4.Modify the file omniORB.cfg with the following values: scanGranularity=1 inConScanPeriod=15

outConScanPeriod=10

If omniORB.cfg is not yet present in its directory, copy its template to this directory and add the above lines to it.

Linux specific

omniORB.cfg is located in the directory /etc/opt/fse, and its template is located in the directory /opt/fse/newconfig.

Windows specific

omniORB.cfg is located in the directory %InstallPath%\etc. Its template can be found in the directory %InstallPath%\newconfig.

5.Start the FSE implementation: fse --start

The omniORB/CORBA naming service is started automatically before the FSE processes.

CAUTION: If you configure or modify omniORB.cfg only to prevent exhaustion of CORBA sockets, you need to consider that omniORB.cfg affects configuration of the FSE interprocess communication. For more information, see the FSE User’s Guide, chapter ”Configuring FSE”, section ”Reconfiguring FSE interprocess communication”.

Migrating to a newer tape drive technology

New tape drives, such as the LTO Ultrium 3 tape drive, are backward compatible with LTO Ultrium 2 tape media. For example, an LTO Ultrium 3 tape drive can read and write onto LTO Ultrium 2 tapes. However, the opposite is not true. LTO Ultrium 2 drives cannot read and write onto LTO Ultrium 3 tapes.

FSE does not distinguish between LTO Ultrium 2 and LTO Ultrium 3 tape drives. If both LTO Ultrium 2 and LTO Ultrium 3 drives are present in the same library, FSE may attempt to load an LTO Ultrium 3 tape into an LTO Ultrium 2 drive. The will result in a tape load error. If both drive technologies are present in the same tape library, disable the LTO Ultrium 2 drives or remove them from the FSE configuration before using LTO Ultrium tape media. For these changes, use the commands fsedrive --disableand

fsedrive --remove, respectively.

Linux-specific recommendations

Verifying SCSI IDs after addition or removal of SCSI devices

Adding or removing SCSI devices on the consolidated FSE system or FSE server may result in the Linux host redistributing the SCSI special device file names (SCSI IDs). If this occurs, the SCSI IDs may no longer match those specified in the FSE library and FSE drive configuration files, which may lead to errors in the FSE implementation.

If any changes are made to the physical hardware, for example, if devices are added or removed, HP recommends that you thoroughly check all SCSI IDs afterwards. If necessary, use the commands fselibrary --modifyand fsedrive --modifyto modify the FSE library and FSE drive configurations to match the updated SCSI IDs. Note that mount points of the disk media may also be affected.

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.
