Hello Lucas,

Here are some tips about Thick LUN and Thin LUN.

Concept:

Thick LUN: Traditional non-thinly configured LUN, the size of the LUN == the allocated capacity, that is, there is a fixed quota regardless of how much it is used.

Thin LUN : thinly provisioned LUN, the size of the LUN <= the allocated capacity, that is, how much capacity is used, how much hard disk resources are allocated.


Advantages and disadvantages:

Thick LUN:

Advantages: Suitable for sequential read and write scenarios, high performance

Disadvantages: Lower storage space utilization


Thin LUN:

Advantages: Utilize storage space fully and flexibly

Disadvantages: Lower performance. Because the capacity is continuously allocated during use, and needs to be initialized, which will reduce the read and write performance. The sequential read and write performance is not high. Because the capacity is continuously allocated during use, and the data is not continuous, which is not suitable for continuous data reading and writing.
