Which of the following statements regarding the Huawei Oceanstor V3 hierarchical storage and Smart Cache is correct?

• A client business IO load random read that accounts for more than 60% using SATA, SAS for staging storage, use SSD to do cache, so it will effectively reduce costs and improve random performance indicators
• If hot spot data is scattered and changing rapidly, it is recommended to use tiered storage
• If there are many SSDs and hotspots, Smart Cache is the best choice
• If you have a small amount of SSD data, use a tiered storage disk for more utilization

Which description of the the OceanStor V3 file system snapshot feature is wrong?

• In File System Snapshot when you create a snapshot, you simply copy the root of the file system and save it to form a snapshot of the file system.
• Deletion Snapshots use a mechanism for reclaiming space, so snapshot data space is immediately freed after snapshots have been deleted.
• After creating a snapshot in the File System, as the main file system is continuously updated, the original data block will gradually become the space occupied by this quick debt. However, a newly written data will not be included in the snapshot space.
• File system snapshot data can not be deleted directly, and only after the snapshot has been deleted, this part of the space can be released.

A customer's database application is running on an OceanStor V3 storage system. The database uses six LUNs. The customer wants to migrate data from the OceanStor V3 storage system to an OceanStor 18000 series storage system based on the functions provided at the storage side. Which statements are true?(Multiple Choice)

• If you use the HyperReplication function to migrate data on multiple LUNs used by the database, you must add multiple remote replication tasks to one consistency group.
• The HyperReplication function can implement online data migration.
• After data is migrated using HyperCopy or HyperReplication, services can be started without the need to make any configuration on the host.
• If data is migrated using HyperCopy, the migration speed can be dynamically changed during the copy process.
