Aggregate Handling and Storage Procedures. The manufacturing of construction aggregates requires careful and continuous production control in the plant. The result is a quality product that is stored in stockpiles or silos at the production site. Quality measures don't stop there.
Although placing product in a stockpile endangers its quality, stockpiling is a vital link in the aggregate production process. It is a storage method that ensures material availability. The rate of production often differs from the rate at which the product is required for a given application, and stockpiles help to absorb the difference.

Typically we'll create large aggregates based on a homogeneous disk type. 15K SAS disks in one aggregate, SATA in another. In some cases when it's only a single type of disk, we'd have 60 15K disks in one aggregate and 60 in other (assigned to each controller respectively). The idea here is that more spindles gives us the most performance.
