System FSM Buffer Cache and Memory Allocation Settings
The memory allocation settings presented in the table below are general recommendations. Other settings may be reasonable, depending on specific conditions and workloads.

32 GB |
M330 |
24 GB | 2 GB per file system (e.g. 4 x 2 GB = 8 GB) | 256 K inodes per file system (e.g. 4 x ~ 0.5 GB = 2 GB) | 5 GB (default is 2 GB) |
18 GB |
*For systems not running the maximum number of file systems, it is recommended that memory be provisioned to increase the FSM BufferCacheSize setting to a value up to 8 GB and the FSM InodeCacheSize setting to a value up to 512 K. Increasing these values may improve file operation performance on systems with many concurrently active files. |
