....processes. 4. I. Model validation In order to evaluate the accuracy of the results produced by the simulation model, we first configured the model to reflect, as accurately as possible, the characteristics of Gamma and then ran a number of experiments without replication. As described in [14], the model predicted the actually measured performance of Gamma with less than a 10 margin of error. 4.2. Experimental design Typically, system throughput and average response time are the two key metrics used to evaluate a system. However, since our model simulates a closed system, response ....

....the array in order to satisfy a single disk request. In such cases, the failed disk array will be restricted to serve only one request at a time and its performance will degrade significantly. The availability of a system or data file is greatly influenced by the way data files are placed on disks [Hsia90b] and the time needed to recover or restore a failed disk node. The longer the recovery time is the higher the probability that a second failure will render data unavailable. With an identical copy approach, data can be copied from the intact disk(s) to the new disk after the broken disk has been ....
