What is Pay per use? Pay per use (PPU) is a pricing model in which you are charged for actual core usage. You acquire a specific hardware platform and number of cores, and are charged for the actual usage, based on one of the following HP contractual agreements:

	NOTE: Currently, the “Core Percent Utilization” pricing model is the only one provided on Integrity servers running Windows Server 2003.

What is the benefit of Pay per use, as opposed to traditional core usage financing? With Pay per use, your billing is based on actual core usage. The billing amounts vary as your core usage increases or decreases. This is different than the traditional financing approaches that are based on fixed-payment amounts for the coverage period.

Is Pay per use the same as leasing? No. A lease is a fixed monthly payment. PPU charges vary on actual core usage. With PPU, a fixed charge and a variable charge appear on your monthly statement. The fixed charge is similar to a standard lease, and the variable charge is based on actual core usage.

Can one HP enterprise server be under both a Pay per use (PPU) and Instant Capacity (formerly iCOD) contract at the same time? No, the PPU and Instant Capacity software bundles are mutually exclusive. They can both be installed on the same HP enterprise server, but because the server can only be purchased using either PPU or Instant Capacity (but not both), the server can only be configured for the purchased pricing solution.
