Most storage managers agree that storage costs are not just the price of buying physical hardware. IT managers often add maintenance costs and the cost of running and managing storage for administrators. 　　In fact, there are more components to the true cost of storage, and determining the true cost of storage systems requires determining the cost of x capacity to provide a level of Y-level performance to an application. Let's take a look at the cost of providing capacity, for example, if you have an application that requires a net usable capacity of terabytes, how much storage do you need to actually buy to ensure that terabytes of storage? Obviously ...
