Which are the key parameters used to evaluate the performance of an N8500 clustered NAS storage system? (Select three.)

A. Number of network ports per engine node

B. Number and model of CPUs and memory capacity per engine node

C. Communication links between the NAS engine and the storage units

D. NAS engine operating system and version

Which of the following statements about reading and writing an N8500 clustered NAS file system mirror and the best practices are correct? (Select three)

A. Equivalent to RAID 01, Mirrored-stripe is to perform file system mirroring based on striping, A mirror provides data redundancy, and data is distributed across multiple disks.

B. Mirror is equivalent to RAID 1, Data that needs to be written to a file system is simultaneously written to two mirrors and data is read from the two mirrors based on a round- robin policy (I/Os are evenly distributed to paths in a round-robin manner).

C. Regarding the use of Mirror, it is recommended that the space of the source file system be provided by one storage array and that of the mirrored file system be provided by another. Mirror is recommended for scenarios that require high reliability.

D. Mirrored-stripe is suitable for scenarios that require high reliability. The performance of Mirrored-stripe is the same as that of Mirror.
