Instant Capacity Components
Overview
The Instant Capacity software monitors and enforces compliance with
licensing agreements. It authorizes or denies activation of system
components (CPUs, cells, memory) based on a complex-wide license
database. See “License Requirement” on page 27 for details on licensing
components. Activation of components is restricted according to
complex-wide compliance.
To activate an unlicensed component, a license must first be purchased
from HP, and a right-to-use (RTU) codeword must be applied to the
complex. See “Applying a Right-To-Use (RTU) Codeword” on page 54 for
details.
Processors
The Instant Capacity software enforces the number of licensed and
unlicensed processors, on a complex-wide basis. That is, the compliance
of an Instant Capacity system is determined by comparing the number of
inactive processors with the expected number of unlicensed (Instant
Capacity) processors for the entire complex, according to the contract
with HP. Available processor licenses may be used to activate any
processor in an active cell board.
NOTE Licensing is system-wide only. If system components are moved from one
system to another, the counts of allowable active and inactive
components do not change for either system. In particular, this means
that the removal of inactive components from a system can cause that
system to be out of compliance with the Instant Capacity contract
because there are fewer inactive components than the complex-wide
count of unlicensed components. Or the system may even become
unusable as in the case where enough other processors must be made
inactive to meet compliance, but there is no longer at least one active
(licensed) processor per configured cell.
