The only thing that I'd like to see, at some point in time, is having the storage array being able to detect a ransomware attack. When you get hit by a ransomware it rewrites every block in your guest's virtual machine. So there should be a way for them to be able to detect that: "Hey, this is unusual, to see every block of this guest being rewritten all at one time," and then flag that as potential malware or ransomware.
