NOTE: Commands for managing LVM logical volumes begin with the letters lv (logical volume) and are located in the /sbin directory.

In the following example, LVM logical volumes are created on the LVM volume group vg_fse for the important directories that FSE uses, namely:

•/var/opt/fse/

•/var/opt/fse/part/

•/var/opt/fse/fri/

•/var/opt/fse/log/

•/var/opt/fse/diskbuf/FileSystemMountPoint

Optional additional file systems assigned to FSE disk buffer will use mount points conforming to the following scheme, where NewFileSystemMountPoint is a unique subdirectory name:

•/var/opt/fse/diskbuf/NewFileSystemMountPoint

You should use logical volume names according to your preferences and sizes that correspond to your actual LVM volume group configuration:

#lvcreate -L 6G -n fsevar vg_fse

#lvcreate -L 6G -n fsepart vg_fse

#lvcreate -L 6G -n fsefri vg_fse

#lvcreate -L 6G -n fselog vg_fse

#lvcreate -L 20G -n fsediskbuf vg_fse

In case of additional file systems assigned to the FSE disk buffer, you should use the following command for creation of the LVM logical volume for each of them:

# lvcreate -L 20G -n fsediskbufNumber vg_fse

NOTE: You need to leave some free space for optional LVM snapshot volumes on the LVM volume group, which are created during backup of the FSE implementation. The size of the reserved space should be approximately 15-20 % of the whole LVM volume group size, as recommended by the LVM developers.

The exact value depends on the actual load of the LVM volumes: it should be increased if frequent changes to the HSM file systems are expected during the FSE backup or if the FSE backup process is expected to last longer.

The /var/opt/fse/log/debug directory is not as critical as others, and can be placed on an ordinary file system. For more details on configuration, see chapter ”Introduction and preparation basics”, section ”Estimating the size of file systems”, subsection ”Storage space for FSE debug files”.

Step 5: Create LVM logical volumes for HSM file systems

To create the LVM logical volume for a single HSM file system that will actually contain user files, use the lvcreate command. Use a logical volume name according to your preferences, and a size that corresponds to your actual LVM volume group configuration:

# lvcreate -L 400G -n fsefs_01 vg_fsefs

Repeat the procedure to create the LVM logical volumes for each additional HSM file system you are going to use.

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.
