There are various parameters in the dCache PoolManager subsystem, determining the system behaviour on particular events. These are for example the cost threshold at which the PoolManager initiates pool to pool transfers to smooth the overall system load, or the balance between performance and disk space related costs to optimize request distribution among data pools. A defined set of parameters can have different values for different partitions of the complete dCache instance. dCache provides a web page, listing partitions, assigned parameters and inheritance information.
