The HP Instant Capacity (iCAP) and HP Pay per use (PPU) software products are a part of the HP Utility Pricing Solutions program. iCAP is a purchase model in which capacity can be instantly increased to accommodate increasing demands. PPU is a lease model in which customers are charged only for actual processor usage.

HP Instant Capacity

The HP Instant Capacity (iCAP) version B.11.11.08.01 software (product number B9073BA) provides the ability to instantly increase or decrease processing capacity on specified HP Enterprise servers.

Summary of Change

iCAP has been updated to version B.11.11.08.01 to include modifications to the installation procedure, to incorporate changes to GiCAP grouping rules and icapstatus command output, and to incorporate several defect fixes.

HP Pay per use

The HP Pay per use (PPU) program is a lease model in which customers are charged only for the computing capacity that they use. The PPU software (HP product T2351AA) provides services for metering resource utilization. The current version is B.11.11.08.00.01.

Summary of Change

  • In September 2005, PPU version B.07.00.01 was delivered on the HP-UX 11i v1 Operating Environments and provided the following features:

    • The name of the product (formerly Pay Per Use) was changed to HP Pay per use.

    • The software has been updated to include the required SSL certificate for communication from the PPU software to the utility meter.

    • The current release of PPU (version B.07.00.01) allows either pricing model, CPU active or percent utilization, to be used as the metric.

    Additionally, a processor cap can be specified with the current version of PPU.

  • In June 2006, PPU version B.08.00 was delivered on the HP-UX 11i v1 Application Release (AR) media and provided the following features:

    • Support for HP Integrity Virtual Machines Environment.

    • PPU now requires NParProvider version B.12.01.06.01 or greater.

    • The Utility Pricing program changed terminology to be consistent with the new HP definitions of “processor,” “CPU” and “core.” The two metrics previously known as “Percent CPU” and “Active CPU” are now called “Percent Core” and “Active Core.”

  • In December 2006, PPU version B.08.00.01 is delivered on the HP-UX 11i v1 Operating Environments and provides the following features:

    • Defect fix for error message reported when cells are powered down.

    • Defect fix for incorrect reporting of TotalCPUs.

Impact

PPU Version B.11.11.08.00.01 supersedes version B.11.11.08.00 on HP-UX 11i v1.

The two metrics for measuring pricing and utilization are now called Percent Core and Active Core (previously known as Percent CPU or Processor Percent, and Active CPU or Number Active Processors). The billing amounts vary as your core usage increases or decreases. This is different than traditional financing approaches that are based on fixed-payment amounts for a specified period. PPU can be run in an HP Integrity Virtual Machines environment (HPVM). In this case, the usage information for billing purposes is still the overall usage for the host. However, you can examine the usage report at the portal to see a detailed breakdown of the usage for each Virtual Machine (also called a “guest”). In an HPVM environment, PPU needs to be installed and configured only on the host, not on the guest Virtual Machines. (PPU commands are therefore only executed on the host.)

Compatibility

While the utilization metric names have changed, as well as other terminology, the methods of measuring resource utilization have not changed. There are no known compatibility issues.

Performance

There are no known performance issues.
