dc.description.abstract | There is a growing demand for high reliability beyond what current RAID can provide and there are various levels of user demand for data reliability. An efficient data placement scheme called RM2 has been proposed in [10], which makes a disk array system resistant to double disk failures. In this paper, we consider how to choose an optimal striping unit for RM2 particularly when no workload information is available except read/write ratio. For experimental purposes, we develop a disk array simulator incorporating RM2 as one of the data placement schemes including other schemes of RAID levels. In the case of disk read operations; it is shown that RM2 has an optimal striping unit of 4/3T for large requests and 8/3T for small requests, where T represents the size of a single track. We have also shown that, if any disk write operations are involved, an optimal striping unit becomes 1/3T for large requests and 8/3T for small requests. | - |
