A. True

B. False

Which of the following statement about SmartVirtualization heterogeneous software is used to identify and handle compatibility issues between heterogeneous storage devices in a timely manner?

A. The physical space required by the eDevLUN data volume occupies the space of the local system

B. LUNs in the SmartVirtualization heterogeneous storage systems are mapped to the local system.

Therefore, you can discover the LUNs in the local storage system. However, the data is not managed

by the local storage system.

C. An eDevLUN data volume is a logical abstraction of external LUN data

D. In the SmartVirtualization, feature heterogeneous storage systems include only storage systems of other mainstream vendors.

In the cloud data center migration scenario, which of the following statements about configuring eDevLUNs for heterogeneous virtualization is correct?

A. The read/write policy of eDevLUNs "write-back" applies to random access services, ensuring that data in the cache is cached as long as possible to improve the read hit ratio.

B. The default read/write policy of eDevLUNs is applicable to common services to balance the hit ratio and disk access performance.

C. The read/write policy "Pairing" of eDevLUNs applies to sequential access services to release cache resources for other services as soon as possible.

D. When the eDevLUN reads data, it reads the data to be read from the hard disk in advance based on the specified policy.
