now , I want to expand this 5 new disks . increase iosp that it will have better loading?
Ans: If you add this 5 drives under a new VDG but under same Pool then space and IOPs both will increase
i have two controller that i put new vdg to new controller b , is it better?
Ans: These new 5 drives with new VDG and new volume if you are planning to take care new VMs then it's good to plan them for Pool B so that load balance will happen. Otherwise if all VMs part of same Pool then all writes will happen primarily through Controller A only which may impact in performance
controller a and pool a is same item?
Ans: Technically its not same. But Controller A takes care of Pool A and Controller B takes care of Pool B
Hope this helps!
