• Question 409:

  In the Huawei storage system using RAID2.0+ technology, regarding the difference between Thick LUN and Thin LUN, the following

  Which description is correct? (Multiple choices)

  A. Allocate storage capacity when Thick LUN is created
  B. The storage capacity is not allocated by default when the Thin LUN is created, and the storage capacity is allocated when data is written
  C. Thin LUN is more flexible than Thick LUN, and has better performance during sequential read and write of large IO
  D. Thin LUN makes the entire storage space utilization rate higher
  A. Allocate storage capacity when Thick LUN is created
  B. The storage capacity is not allocated by default when the Thin LUN is created, and the storage capacity is allocated when data is written
  D. Thin LUN makes the entire storage space utilization rate higher

  ---

  Explanation

  Resolution: A LUN can be created as a Thick LUN and Thin LUN. Thick LUN will be allocated from the storage pool in advance Storage capacity, even if no user data is stored on the Thick LUN. Thin LUNs are not pre- allocated from the storage pool For storage capacity, only when user data is written to the thin LUN will the actual storage capacity be allocated from the storage pool. Sequential read: Since thin LUN dynamically allocates storage resources according to the actual needs of users, space allocation exists in time Discontinuity, so it will affect the continuity of the space mapped on the disk. When thick LUN is created, the system Automatic resource allocation technology allocates storage resources from storage resources at one time, which maximizes its mapping to Space continuity on the disk. Sequential reading of mechanical disks is more efficient, so thick LUNs

  perform better when reading sequentially For thin LUN.

• Question 410:

  OceanStor V3 series storage can only support iSCSI or FC host links separately, not both Connect to the network.

  A. TRUE
  B. FALSE
  B. FALSE
