HP Instant Capacity Version 10.x User Guide (762794-001, March 2014)

to the Group Manager system enables the addition of members with iCAP components to groups.
In addition, you must acquire grouping rules from the portal and apply those rules to the Group
Manager system. GiCAP sharing rights and grouping rules are described in Chapter 7 (page 67).
All GiCAP Group Manager systems and group members must run iCAP version 9.0 or later.
iCAP allows deactivation of cores on non-iCAP systems (those without any iCAP components),
allowing such systems to participate in a GiCAP group and loan usage rights to iCAP systems. A
GiCAP group consists of servers that are allowed to be grouped together according to a set of
grouping rules defined by HP. These grouping rules must be acquired from the Utility Pricing
Solutions portal and applied to the Group Manager system before groups can be created. For
more information, see “GiCAP grouping rules” (page 70).
iCAP codewords
iCAP uses codewords for several purposes: to adjust available usage rights for system components
(RTU codewords), to apply temporary capacity to the system, and to apply sharing rights to a
GiCAP Group Manager system to enable the creation of one or more groups.
All types of codewords must be purchased as specific product numbers from HP. After purchase,
the actual codeword (an encrypted string) can be retrieved from the Utility Pricing Solutions web
portal. When you retrieve codewords from the portal, you must provide the sales order number
for the codeword purchase and the serial number of the system. For more information about
purchasing codewords, see the Utility Pricing Solutions web portal information in “System overview”
(page 11).
After obtaining from the portal, the rules and uses of GiCAP codewords are very different from
other types of iCAP codewords. The GiCAP codewords are described in “GiCAP sharing rights”
(page 70) and are referred to as “GiCAP codewords”. Other types of codewords are referred to
as “Instant Capacity codewords”.
The following iCAP codewords are applied to a server using the icapmodify -C command:
• Core RTU
• Cell board RTU
• Memory RTU
• Temporary capacity
For details about using temporary capacity codewords, see “Acquiring and configuring TiCAP”
(page 54).
Application of an RTU codeword adjusts the number of component-specific usage rights on the
system. As a result, more components can be active simultaneously.
IMPORTANT: iCAP codewords are based on both the serial number of a system and a unique
sequencing value for that server. These codewords must be applied in the sequence in which they
are obtained for a particular server. They can be applied to any partition on the server.
TiCAP
You can purchase an amount of temporary processing capacity for your iCAP system. TiCAP is
purchased in units of processing days. TiCAP allows one or more cores beyond the count allowed
by the available usage rights to be activated for up to the specified period of prepaid minutes
without requiring the purchase of additional usage rights.
You can activate and deactivate cores according to your needs until the activation time equals
your prepaid temporary capacity duration. For example, with a prepaid duration of 30 days of
temporary capacity, you can activate one core for 30 days, or four cores for one hour a day for
180 days (or any combination that totals 43,200 minutes).
