Storage Capacities and Resources

Your ability to meet your storage-capacity requirements depends on the following criteria:

• The types of libraries you have
• The number of each type you have
• The types of media each library uses

After you have identified types and numbers of libraries that will be available, you can calculate the capacity of each library using the following formula:

totalcapacity = numberslotsavailable × mediaelementcapacity

In this formula, the numberslotsavailable is the number of slots available in the robotic library and mediaelementcapacity is the capacity of the media elements used by the installed drives.
