HP File System Extender (FSE) specification

Linux specific

On Linux platform, FSE uses a SCSI generic (sg) driver for accessing SCSI libraries and drives. The sg driver is an upper level SCSI subsystem device driver that enables user applications to send SCSI commands to relevant devices. It is capable of addressing up to 256 SCSI devices.

When configuring libraries and drives, you need to specify their control device file names: each device file name corresponds to one attached SCSI device. Control device file names are located in the /dev directory. Therefore, the specified control device for library and drive takes the form /dev/sgX, where X is a number between 0 and 255.

Windows specific

Before configuring FSE drives, ensure that the drivers of all tape drives to be used as FSE drives are disabled on the system that hosts the consolidated FSE system or FSE server. For more information on disabling the tape drive drivers, see the FSE installation guide for Windows.

On Windows platform, FSE identifies attached SCSI devices (libraries and drives) by specifying port, bus, target, and LUN in the form of id:P:B:T:L, where:

P ..... SCSI port number (HBA number) to which the device is connected.

B ..... SCSI bus/channel number on the HBA to which the device is connected.

T ..... target ID to which the device is connected.

L ..... logical unit number (LUN) of the device.

Library and drive configuration procedure

NOTE: To use disk media, no library and drive configuration is needed.

In general, you configure an FSE library or FSE drive as follows:

1.On the consolidated FSE system or FSE server, invoke the fse_scsi tool to get the control device files of the connected tape libraries and tape drives:

Linux specific

#/opt/fse/sbin/tools/fse_scsi --scan

** /dev/sg0	id:0:0:0:0
SCSI device ID: port 0, ch 0,		id 0, lun 0,		type Medium Changer 8
Device: HP	MSL6000 Series		0430 ser	#:3G2BLBD358D0 std :2

** /dev/sg1	id:1:0:0:0
SCSI device ID: port 1, ch 0,		id 0, lun 0,		type Tape 1
Device: HP	Ultrium 2-SCSI		F59W ser	#:HUL2K00119	std :3

Done!

NOTE: If the Library Agent is running, the device for the library used by the agent is not seen in the list.

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.
