Ordinary LAN connection

NOTE: SUSE Linux specific

On a SUSE Linux system, do not run YaST2 after you have configured this FSE host to use a private network for the FSE interprocess communication. Running YaST2 modifies /etc/hosts in such a way that the subsequent FSE implementation startups fail.

Alternatively, you can modify /etc/sysconfig/suseconfig by changing the line CHECK_ETC_HOSTS="yes" to CHECK_ETC_HOSTS="no". You can then run YaST2 without affecting FSE operation, but you cannot modify host names with it.

5.Start the omniNames service and all FSE processes using the fse --startcommand.

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

CAUTION: In the following procedures for configuring a LAN connection, if you reconfigure a system with several network adapters enabled, you need to configure the parameters in the section

---Private network parameters --- in the omniORB.cfg file as described in the procedures for private network communication configuration, instead of commenting them out.

In this case, the parameters you specify in omniORB.cfg must be verified against the actual LAN configuration for that system.

Reconfiguring communication on a consolidated FSE system or on an FSE server

This section describes the configuration procedure for the following situations:

•if your FSE implementation consists of a consolidated FSE system and you do not plan to connect external FSE clients to it.

•if you want your external FSE clients to communicate with the consolidated FSE system or with the FSE server through an ordinary LAN.

Perform the following steps:

1.Ensure that the value of the server variable in services.cfg equals the fully-qualified domain name (FQDN) that identifies the consolidated FSE system or the FSE server inside the LAN.

The following is an example of a properly configured services.cfg file in FSE implementation using an ordinary LAN. The file can also include the hostname variable, but this variable is redundant in such FSE implementation.

server = fse-server1.company.com

2.In the omniORB.cfg file on the consolidated FSE system or the FSE server, comment out all parameters in the section --- Private network parameters ---and save the changes.

Private network connection

If your external (distributed) FSE clients will use a private network for communicating with the FSE server, make the following modifications on the FSE server:

1.Add the hostname variable (if not present) to services.cfg and set its value to the fully-qualified domain name (FQDN) that identifies the system inside the private network.

The following is an example of a correctly configured services.cfg file in FSE implementations using a private network. The server variable is redundant in such FSE implementation.

hostname = fseserver.fsenet

server = fseserver.fsenet

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.
