8.16 HP Utility Meter User's Guide (June 2010)

NOTE: A single Utility Meter can meter up to 1,000 metered resources (server partitions, storage devices,
and switch devices).
The Utility Meter sends PPU and URS 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 are 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. 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 or SAN switch ports).
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 the flow of metered Usage Data to HP, see Figure 1-1.
Figure 1-1 Flow of Metered Usage Data
The communication from the Utility Meter to the PPU Partition runs over https (TCP port 5989). This port must
be open from the Utility Meter to any PPU partition that needs to be metered. No non-transparent proxy
server can be configured between the PPU partition(s) and the Utility Meter.
The communication from the Utility Meter to disk arrays runs over TCP ports that are described in the manuals
for Command View XP Advanced Edition and CV EVA. Please consult these manuals for more information.
The communication from the Utility Meter to VLS devices uses SSH without passwords so that CLI commands
on the VLS device can be executed from the Utility Meter.
The communication from the Utility Meter to SAN switches can use either https or http. Certificates can be
implemented. For HP/Brocade SAN switches, the default ports for http and https for CIM traffic can be
changed by the user. For Cisco switches the port numbers are fixed to 5988 for http and 5989 for https
