問題 #2

Huawei OceanStor 9000 provided sharing ways are mainly NFS and CIFS share, mount NFS share in the Linux operating system, you can set some parameters to improve performance, which of the following description is correct? (Multiple choice)

A. async, allow data to be written asynchronously. After synchronization write to request NFS server must brush each data into the hard disk, then can return successfully, the delay is higher.
B. nolock, if there are shared files between the NFS clients, can use this parameter. Reduce the overhead which server-side file lock brings.
C. rsize/wsize, read and write the maximum size of the block each time, it is recommended to adjust the maximum value. Generally, under the environment of linux operating system, a maximum value is 1M.
D. noatime, if it is not required to record the file access time, can increase this parameter. Avoid frequent access; modify the overhead which access time brings.

問題 #3

C. After SmartMiaration is configured, data changes of the source LUN are synchronized through dual-write and DCL during the service running to ensure data consistency after the migration.
D. Due to business needs, the SmartMigration feature can be used to migrate LUN data from NL-SAS storage media to SAS storage media to improve business performance.
