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.
The Underlying Storage System
The performance characteristics of the underlying storage system are the most critical factors for file system performance. Typically, RAID storage systems provide many tuning options for cache settings, RAID level, segment size, stripe size, and so on.
