This topic helps you determine the number of metadata servers that are needed to handle the workload based on the number of hard disk drive available to SAN File System.
This method for determining the number of metadata servers looks at the number of physical data disk drives in the SAN File System configuration and performs a calculation from this number. This method relies on the fact that hard disk drives can provide a fixed amount of I/O per drive. The more drives, the more I/O throughput that can be obtained. As the number of I/Os is scaled up, the number of metadata server transactions is also scaled up, which has a direct correlation to how many metadata servers are required.
metadata servers = ( hard disk drives / 50 ) * application factor
