Abstract
With the ever increasing popularity of web service and e-commerce, there is a high demand on data storage. Because of the development of Internet infrastructure and the low cost of deployment, implementing storage over IP has become a trend. For the utilization of network storage, one important issue is the way to achieve data integrity. Usually, the application of Internet Small Computer System Interface (iSCSI), which is a kind of network storage technology, is to store some read-only or important data remotely. I/O requests, which may cause data loss and data error, are frequent in a traditional distributed network storage system like iSCSI. In this paper, the data integrity of iSCSI is analyzed and Dm-verity mechanism is utilized to provide read-only transparent integrity checking for iSCSI, which could avert data loss and data error, increasing overall system reliability.
