Definition of Reserve storage:
Space within a warehouse that is allocated to storage of buffer inventory. Stock-keeping units (SKUs) from the reserve storage area can be rapidly relocated to replenish the inventory in the active pick area. Having space reserved for extra inventory on site reduces the risk of running out of product during times of peak demand. However, this benefit must be weighed against the ongoing cost of leasing or owning additional square footage to house the inventory.
