Thread Limits

The THREADS column allows the administrator to specify how many threads a PFS I/O daemon will spawn for the disk storage device or devices it controls. The number of threads needed by a given PFS I/O server node will depend primarily on the performance capabilities of its disk subsystem.

• For a storage object with a single disk or a small storage array, one thread may be enough to exploit the storage unit's maximum I/O potential.

• For a more powerful storage array, two or more threads may be needed to make full use of the available bandwidth.
