IBM GPFS
The IBM General Parallel File System (GPFS) is a high-performance cluster file system, providing concurrent access to a single file system or set of file systems from multiple nodes. These nodes can be all SAN attached, or a combination of SAN and network attached. This enables high performance access to a common set of data, in order to support a scale-out solution or provide a high availability platform.
When using CTERA Portal with IBM GPFS, CTERA Portal servers have active-active access to the stored data. This means that each CTERA Portal server has equal and independent access to the data stored by all other CTERA Portal servers. If one CTERA Portal server fails, another server immediately and transparently takes its place.
The minimum version of GPS supported by CTERA Portal is 4.0.
Note: When using this type of storage node, it is recommended to set the deduplication block size to 512KB.
Storage Path – The path where files should be stored in the GPFS file system.
Files per Folder – The maximum number of files to store in a folder. The default value is 1024.
Use fsync – Blocks of data should be flushed to disk immediately. Using fsync prevents data loss in the event of a power failure.
