8.14.01 HP Utility Meter User's Guide (June 2009)

• A network configuration, for the network that the Utility Meter is installed on, has been changed.

• A proper shutdown was not performed on the PPU partition, resulting in the PPU partition sitting at a

boot prompt and still being detected by one of the other partitions. See Troubleshooting Overview.

• The email or HTTPS configuration on the customer's network was modified and the change has broken

the transport of the usage data to HP.

• For URS XP installations only: The HP StorageWorks XP Command View Advanced Edition Command

Line Interface (CLI) software (or the required 6.0 version) is not installed or is not configured to avoid

CLI conflicts. For details of the XP CLI installation and configuration, see URS XP Only – Installing the

XP CVAE CLI Software.

• For URS EVA installations only: The HP StorageWorks Storage System Scripting Utility software (or the

required 8.0 version) is not installed or is not configured properly. For details of the EVA SSSU installation

and configuration, see URS EVA Only – Installing the CV EVA SSSU Software.

• SMI-S Agent for HP/Brocade is down or unreachable.

• The CIM server on the Cisco switch is not enabled.

1.8 Data Transport Methods

HP’s PPU/URS metering system is designed with the customer’s security and confidentiality foremost in mind.

Usage data flows unidirectionally from the Utility Meter to HP’s usage database. The Utility Meter can be

configured with either of the following data transport methods:

• HTTPS – HTTPS is the default data transport between the Utility Meter and HP. SSL encryption, with

1024-bit key, is used to ensure data privacy. The HTTPS connection to HP can be through a proxy

server (optional) if the customer’s network does not permit direct HTTPS connections to the Internet.

HTTPS is the recommended data transport between the Utility Meter and HP.

• email – Customers can also choose to transport data using encrypted email. The email data transport

is unidirectional – it only transmits usage data from the Utility Meter to HP. The Utility Meter does not

receive any email from HP. A disadvantage of this data transport method is the absence of a

“closed-loop” receipt after the information was successfully transmitted to HP.

CAUTION: The datagram nature of email does not verify that usage data has reached HP. Consequently,

there is no retransmission mechanism to recover from transmission failures. Using the email transport can

result in lost usage data.

For details on verifying the configured data transport method on a fully functioning Utility Meter system, see

Verifying the Utility Meter Data Transport Method.

The frequency of usage reports sent from the Utility Meter to HP are:

• For PPU: 48 times per day per partition

• For URS: 12 times per day per disk array; 4 times per day per SAN switche

1.9 Utility Pricing Solutions Web Portal

HP maintains a public Web portal that displays the usage data for UPS computing resources under a PPU

or URS contract. The Utility Pricing Solutions (UPS) Web portal is located at: http://www.hp.com/go/

payperuse. Access to the portal is controlled by a username/password. All users of the portal must first

portal is free. The UPS Web portal provides usage information for the following UPS programs:

• Instant Capacity (iCAP)

• Pay per use (PPU)

• Utility Ready Storage (URS)
