The most demanding part of a SQL Server deployment is the storage sub-system. It can be the bottleneck of the solution deployment that can prevent the solution from reaching its full potential. Azure Stack HCI has the capability to effectively pool underlying storage of the available nodes while abstracting the unnecessary underlying complexity from customers and end-users. It delivers on performance and high availability by using concepts such as mirroring, parity, tiering, and more.
