traffic. The ports must be open from the Utility Meter to the SMI-S Agent for HP/Brocade switches and to
any Cisco SAN switch that needs to be metered.
1.2 What is New for Version 8.16
Version 8.16 of the Utility Meter software is the eigth release of the Utility Meter 8.x software. Version 8.16
includes the following changes:
• Support for metering VLS devices
• Support for Continuous Access on EVA
• Support for 2TB SATA disk on XP
• Support for CV XP AE 6.3 and CV EVA 9.2.0
1.3 Recommended Hardware
CAUTION: The hardware used to run the Utility Meter 8.16 software must be used exclusively for the Utility
Meter software application. That is, no other software applications or services are allowed on the Utility
Meter hardware.
The Utility Meter 8.16 software runs on many HP Integrity servers. HP recommends the following Utility Meter
hardware:

Multiple Ethernet ports may be necessary to configure the Utility Meter in the network of the customer. The
URS software supports multiple Ethernet ports.
1.3.1 Swapping Utility Meter Hardware
If you want to change the current Utility Meter hardware to another unit, contact an HP services representative
to perform this task.
1.3.2 Disk Space Requirements
The Utility Meter's /opt and /var directories must have enough disk space allocated to store the Utility
Meter software and the usage reports.
The Utility Meter's /opt directory stores files used by the Utility Meter software. The /opt directory has a
fixed size after the installation of the Utility Meter software, and requires a minimum of 2.5 GB of disk space.
The Utility Meter's /var directory serves as a repository to store the usage reports that are created and sent
to HP and must have enough space allocated to accommodate the usage reports for the duration of the UPS
contract. The size of the Utility Meter's /var directory depends on how many PPU partitions and URS devices
are metered (plus about 500 MB of overhead). Below are calculations for the /var directory disk space
requirements for 1,000 metered resources:
• PPU Partitions — 48 usage reports are created on a daily basis. Each report is 8 KB in size. 90 days
of usage data is retained in /var. For 1,000 PPU partitions to be metered, /var should be
approximately 33.5 GB in size:
48 * 8 * 90 * 1,000 = 34,560,000 (~33.5 GB including 500 MB of overhead).
• URS Disk Arrays — One usage report is created every two hours (12 per day). On average, each
report is 8 KB in size. 90 days of usage data is retained in /var. For 1,000 disk arrays under a URS
contract, /var should be approximately 8.7 GB in size:
12 * 8 * 90 * 1,000 = 8,640,000 (~8.7 GB including 500 MB of overhead).
