Compellent SC4020 access to ESX VSphere 6 without root

Hi,

we would like to access our Compellent sc4020 from our VSphere6 ESX Servers. We cann do it with the root User from the VSphere. But we dont want to give the Compellent root Rights to access to Vspehere. Which rights we need at Vsphere to Create a Server in the Dell Storage Center (16.3.20.22). We try this with only read Rights in Vsphere but it doesn.t work.

Thanks for help
