9.2 HP Pay per use Utility Meter II Software Installation and Configuration Guide (December 2010)

1 Introduction
1.1 Overview
Pay per use (PPU) is part of HP's Utility Pricing Solutions (UPS) program. In this program, customers are
charged according to usage of the PPU resources (servers) under a UPS contract. For more information on
this program, see the HP Utility Pricing Web page: http://www.hp.com/go/utility.
The usage data for PPU is collected by the Utility Meter software, which runs on the Utility Meter server.
Version 9.2 of the HP Utility Meter software requires that the HP Utility Meter server is an HP ProLiant DL
320 server running Red Hat Enterprise Linux Server. For the list of compatible HP servers, see Section 1.2:
“Recommended Hardware”.
The Utility Meter is located at the customer site along with the customer’s PPU resources under a UPS contract.
The Utility Meter retrieves usage information from the UPS resources over TCP/IP and sends the information
securely to HP. There is no geographical limit for the distance between the location of the Utility Meter and
the location of any of the UPS resources.
Version 9.2 of the Utility Meter tracks the usage of:
▲ Enterprise servers – A specific set of HP servers are supported in the PPU program. The supported PPU
enterprise servers are partitionable and each PPU partition must be configured to be metered by the
Utility Meter. See Section 1.2.1: “Supported PPU Servers” for a list of supported servers.
NOTE: A single Utility Meter can meter up to 1,000 metered instances (server partitions).
The Utility Meter sends PPU usage data to HP securely over the Internet through HTTPS or email on a daily
basis. The data is encrypted before transmission. The data received at HP is stored in the Utility Database
that is inside the HP firewall.
The HP Utility Billing Engine processes usage data from the Utility Database once per month and billing
information is sent to the customer. For PPU resources, the monthly bill contains a fixed amount for the
hardware, software and services and a variable amount that represents the processor usage. The variable
amount is based on the usage of the UPS resources (core usage).
Customers can monitor their usage information on the secure HP Utility Pricing Solutions Web Portal located
at: http://www.hp.com/go/payperuse.
For details on the collection and flow of metered Usage Data to HP, see Figure 1-1.
