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

The Utility Meter sends PPU and URS usage data to HP securely over the Internet through HTTPS or email on
a daily basis. Data sent to HP is encrypted before transmitting.
The Utility billing engine processes usage data from the Utility database once per month and billing information
is sent to the customer.
The monthly bill contains a fixed amount (for the hardware, software and services) and a variable amount.
The variable amount is based on the usage of the UPS computing resources (disk space, processor cores,
and switch ports). The PPU and URS usage data is stored in the Utility database at HP on a
per-UPS-computing-resource basis.
Customers can monitor their usage information on the secure HP Utility Pricing Solutions Web Portal: http:/

Figure 1-1 Flow of Metered Usage Data
The communication from the Utility Meter to the PPU Partition is secure WBEM (HTTPS on port 5989). This
port must be open from the Utility Meter to any PPU partition that needs to be metered. Consult the network
administrator if special firewall configuration is necessary.
No proxy server can be configured between the PPU partition(s) and the Utility Meter. There can be a proxy
server between the Utility Meter and the Internet for HTTPS traffic.
The communication from the Utility Meter to SAN switches can use either secure WBEM (HTTPS on port
5989) or HTTP. The default port can be changed by the user. The port must be open from the Utility Meter
to any SAN switch that needs to be metered. Consult the network administrator if special firewall configuration
is necessary.
