9.3 HP Pay per use Utility Meter II Software Installation and Configuration Guide (July 2011)

1 Introduction
1.1 Overview
Pay per use (PPU) and Utility Ready Storage (URS) are part of HP's Utility Pricing Solutions (UPS) program.
In this program, customers are charged according to usage of the PPU resources (servers) and URS resources
(disk arrays) 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 and URS is collected by the Utility Meter software, which runs on the Utility Meter
server. Version 9.3 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 1.5:
“Recommended Hardware”.
The Utility Meter is located at the customer site along with the customer’s PPU and URS 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 9.3 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 1.5.1: “Supported PPU Servers” for a list of supported servers.
• Storage devices – Specific EVA, XP and 3PAR storage devices are supported in the Utility Ready Storage
(URS) program. Usage data is retrieved in the following ways:
• EVA: Usage data is retrieved through the HP StorageWorks Command View EVA Storage System
Scripting Utility (SSSU) software that is installed on the Utility Meter. The SSSU software
communicates with the HP StorageWorks Command View EVA server that is on a separate system.
• XP: Usage data is retrieved through the HP StorageWorks Command View Advanced Edition
Command Line Interface (CVAE CLI) software that is installed on the Utility Meter. The CVAE CLI
software communicates with the HP StorageWorks Command View Advanced Edition server that
is on a separate system.
• 3PAR: Usage data is retrieved through the 3PAR InForm OS software. The compatible WBEM
environment to interface with 3PAR InForm OS is part of the Linux software installed on the Utility
Meter.
NOTE: A single Utility Meter can meter up to 1,000 metered instances (server partitions and storage
devices).
The Utility Meter sends PPU and URS usage data to HP securely over the Internet through HTTPS or email
(using the SMTP protocol) 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). For URS the monthly bill contains only a
variable amount. That amount is the sum of the cost for the hardware, software, services and the usage of
the UPS resources (disk space).
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.
