StorNext File System Tuning

The StorNext File System (SNFS) provides extremely high performance for widely varying scenarios. Many factors determine the level of performance you will realize. In particular, the performance characteristics of the underlying storage system are the most critical factors. However, other components such as the Metadata Network and MDC systems also have a significant effect on performance.

Furthermore, file size mix and application I/O characteristics may also present specific performance requirements, so SNFS provides a wide variety of tunable settings to achieve optimal performance. It is usually best to use the default SNFS settings, because these are designed to provide optimal performance under most scenarios. However, this guide discusses circumstances in which special settings may offer a performance benefit.

Note: The configuration file examples in this guide show both the .cfgx (XML) format used by StorNext for Linux and the .cfg format used by Windows.

For information about locating sample configuration files, see Example FSM Configuration File.

Note: StorNext supports the use of clients running certain older versions of StorNext. When configuring these clients, refer to the StorNext Tuning Guide appropriate for the StorNext version they are running.

Note: If StorNext Appliances are being used, the tuning recommendations found in the appliance-specific documentation should be used in preference to the information in this guide.
