Before learning vcpus, I thought that the storage network was used for Disaster Backup and later I found an unexpected feature, as shown in

No shared storage server is available, and the local VM mainly provides CPU/Meny.

Requirements: high capacity and high performance (1) MB refers to the bandwidth (2) I/0 refers to the number of operations per second (one read/write operation is an IO) (3) how long does it take to read a data?

We use multiple hard disks to copy data at the same time to increase our I/O speed. Second, we can provide data redundancy. The key point is that raid performance and capacity are different.
