Hello, I just need further clarifications regarding the VMAX All FLASH & its cache , how things works ... If we are considering an all flash system then shall we consider to address cache size, all flash shouldn't relay on cache so i need to know if cache is really important in all flash design and should be addressed in such solutions. comparing other systems is cache size is one of the factors that need to be addressed then ? and why how it will be used by the solution .
