Allocation Session Reservation

The Advanced Parameters section of this screen contains a field called Allocation Session Reservation Size. The Allocation Session Reservation feature optimizes on-disk allocation behavior. Allocation requests occur whenever a file is written to an area that has no actual disk space allocated, and these requests are grouped into sessions. The amount you specify at this field determines the size of the chunk of space reserved for a session.

For more information about the Allocation Session Reservation feature, refer to the StorNext 5 Tuning Guide.
