Virtual And Physical Slots

The Virtual Slot allocation is a number of the slot based on sequential numbering of all slots from the zones allocated to a repository.

The Physical Slot allocation is a slot number showing the physical location of a slot in the storage rack that remains unaltered regardless of which repository or customer it is allocated to.

Examples

For this example we will use three LTO storage racks and display results using TapeMaster.

Each of these racks have:

These racks will be assigned names of Rack_01, Rack_02 and Rack_03

Complete Rack And Slots Allocated To One Customer

If these three racks are completely assigned to one repository, there will be 300 virtual slots available for volume allocation.

Assigning volumes to slots

Virtual slotting displays virtual slot numbers.

Physical slotting displays which rack, shelf and slot.

Racks And Slots Assigned To Multiple Customers

If the first 50 slots in storage rack 1 were assigned to customer AAAA, and the rest of the racking, 250 slots, assigned to customer BBBB. For Customer AAAA

Assigning AAAA LTO volumes to slots

Virtual slotting displays virtual slot numbers.

Physical slotting displays which rack, shelf and slot.

For Customer BBBB

Assigning BBBB LTO volumes to slots

Virtual slotting displays virtual slot numbers.

Physical slotting displays which rack, shelf and slot.

While the physical slot location does not change, virtual slotting is determined by where the slotting allocation for each repository starts and finishes with the zones and racks. As you can see in the above example a zone can be assigned to two, or more, customers and each customer has a virtual slot 1 but the physical slot locations are a unique location.
