HP Pay per use (PPU) manual What is New for Version, Reminder of What was New in Version

1.2 What is New for Version 8.13

Version 8.13 of the Utility Meter software is the fifth release of the Utility Meter 8.x software. Version 8.13 includes the following changes:

•Multi-Tiering billing support for XP storage whereby billing can be based on the different disk types in the array. Previously all XP disks were charged the same amount.

•A change in how usage is reported for THP on an XP storage device. Now usage is reported for the amount used whereas previously usage was reported for the amount set aside in THP pools.

•8.13 will be the first release that supports XP20000 and EVA4400.

1.3Reminder of What was New in Version 8.12.03

Version 8.12.03 of the Utility Meter software was the fourth release of the Utility Meter 8.x software. Version 8.12.03 included the following changes:

•An alternative method for metering HP-UX servers was made available. Previously, this could only be accomplished by installing and configuring the PPU Agent software on each HP-UX partition. For Version 8.12.03 HP-UX partitions could be metered by installing the standard CIM/WBEM software, usually done when the OS was installed.

•Metering of Linux partitions (SUSE and RHEL) was possible via the CIM/WBEM software installed on the metered server.

•Version 8.12.03 was the first release that did not support HP-UX 11i v1 for the meter operating system, however, the meter continues to measure servers using HP-UX 11i v1.

1.4Recommended Hardware

CAUTION: The hardware used to run the Utility Meter 8.13 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 8.13 software runs on many HP Integrity servers and HP 9000 servers; however, HP recommends the following minimum Utility Meter hardware:

Table 1-1 Recommended Minimum Hardware

Server Model	Operating System	Memory	Storage	Peripheral	Networking
rp3440	HP-UX 11i v2, or	2 GB	2 x 72 GB in RAID	DVD RW	One Ethernet port
	HP-UX 11i v3		11
rx2620 or rx3600	HP-UX 11i v2 or	2 GB	2 x 72 GB in RAID	DVD RW	One Ethernet port
	HP-UX 11i v3		1 1

1To increase redundancy, the two disks are preferably placed in a RAID 1 configuration using a hardware RAID controller, such as the Smart Array Controller 6402 (HP product number A9890A).

1.4.1Swapping Utility Meter Hardware

If you want to change the current Utility Meter hardware from one HP-UX server to another, you need to contact an HP services representative to perform this task.

1.4.2 Disk Space Requirements

Depending on whether Pay per use (PPU) servers or Utility Ready Storage (URS), or both, are metered by the Utility Meter, the /opt and /var directories must have enough space allocated to accommodate the Utility Meter's usage reports.

The Utility Meter's /opt directory is a fixed size and must have a minimum of 2.5 GB of disk space allocated.
