specific Embodiment
[0035]The present invention implements virtual block storage according to the SCSI protocol through the virtualization technology, and the user's data is not stored locally, but transmitted to the remote end through the network and stored in the remote end. For each user, the system allocates independent virtual block storage for the user. The block storage of different users is completely isolated in use. Each virtual block storage only belongs to one user, that is, block storage B1 only belongs to user A1, and block storage B1 only belongs to user A1. Storage B2 only belongs to user A2. User A1 cannot read the data of user A2, and user A2 cannot read the data of user A1.
[0036] When storing user data, the corresponding hardware calls the method, which includes the following steps:
[0037] Step 1: The system calls the operating system interface to add virtual block storage and mount it to the file system;
[0038] Step 2: The user application program calls the operating ...
