In HUAWEI OceanStor, what unit is Thick LUN applying for space from the storage system?
- A. chunk
- B. grain
- C. stripe
- D. extent
Answer: D
Explanation:
Analysis: Several Extents form a volume, and the volume is externally reflected as the LUN accessed by the host (here LUN is Thick LUN). When processing user read/write requests and data migration, the LUN applies to the storage system Space, free space, and data migration are all performed in units of Extent. For example: when a user creates a LUN, he can refer to The fixed capacity is obtained from a certain storage tier. At this time, the LUN is composed of the specified extent on the certain storage tier. In user After the business starts to run, the storage system will, according to the migration strategy set by the user, for frequently accessed data and less visited Questioned data is migrated between storage tiers (this feature requires the purchase of a SmartTier License). At this time, the data on the LUN It will be distributed to each storage layer of the storage pool in the unit of Extent.
