Licensing

IMPORTANT: In a mixed FSE implementation, if the FSE processes on the consolidated FSE system are restarted, you must restart the FSE processes on all external FSE clients to resume the normal FSE operation.

There are both per machine and capacity-based licenses for HP File System Extender.

•For every machine that runs an FSE client, you need an FSE client license appropriate to the operating system.

•For every machine that runs the FSE server, you need a base license appropriate to the operating system. The base license includes a license to migrate 1 TB to secondary storage managed by the FSE server.

•To migrate more than 1 TB to the secondary storage, you need additional FSE server capacity licenses. These are available in 1 TB increments. The migrated capacity is the sum of all capacity migrated to the secondary storage from all associated FSE clients, including all copies where two or more copies of migrated files are configured, and all versions of modified migrated files.

•To upgrade the FSE client-managed file system to WORM you need a capacity-based license. This is available in 1 TB increments. The capacity for this WORM license is based on the physical capacity occupied by the upgraded FSE file system on the production disk.

Preparing file systems for FSE

In order to optimize operation of the FSE implementation and increase its reliability, you should organize file systems on the host that will become the FSE server, as well as on the FSE client. If you intend to use disk media, you also need to prepare file systems to hold disk media files.

The following sections explain the importance of preparing file systems for FSE operation and provide formulas to estimate the required space for FSE components. These explanations and formulas apply generally when configuring an FSE implementation. The preparation is described in ”Preparing file systems” on page 27.

The following table summarizes the main parameters to be considered when setting up the environment. These parameters are discussed later in this chapter.

12 Introduction and preparation basics

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.
