Some OceanStor V3 Storage Resources Are Mapped to a Host

True/False

Some OceanStor V3 storage resources are mapped to a host as raw devices. The host then creates dedicated file systems on these raw devices. A test tool is used to create a large number of 13 KB files in the file systems. The test tool is also used to read those files randomly for testing the response. In this circumstance, changing the prefetch policy of the tested LUN to constant prefetch and setting the prefetch length to 16 KB can increase the system performance.
