| Abstract: | To investigate the disk scheduling algorithms used in NAS devices, we put forward a new test model based on the NAS device disk scheduling. To show the validity of the test model the performances of typical disk scheduling algorithms used in NAS devices were compared in accordance with HP97560 performance data. The examples were used to illustrate how to use the test model. The test model can reflect the statistical features of disk scheduling algorithm and can help designers of disk scheduling algorithm to analyze the disk scheduling performances of the algorithms. |
