Hello Hemmati,

What is your current OE version? Did you create a Dynamic or Traditional pool? When you configured you pool did you use the follow guide or no? https://dell.to/3NeKzTg

hello 

Is it possible to change the pool type from traditional pools to dynamic pools without losing data?

Unfortunately, it is not possible. It requires deleting the pool and creating a new one.

Hello
I changed the POOL type from Traditional to Dynamic and what happened to the device was that the write speed to the LUN increased to 390 Mbps, but the read speed is 30 Mbps.
