HP Instant Capacity Version 10.x User Guide (5900-1581, March 2011)

After a cell board is activated, all of the cores on the cell board can be activated, depending on
the availability of core usage rights. You might need to acquire additional core usage rights in
order to activate additional cores from the newly activated cell board.
For information about assigning and unassigning a cell board to an nPartition, see “Assigning a
Cell to a Partition” (page 49) and “Unassigning a Cell from a Partition” (page 50).
Ask your HP sales representative about availability of the Instant Capacity Cell Board product.
Ordering Instant Capacity Cell Board
To order the Instant Capacity Cell Board product, do the following:
• Order the appropriate HP product number for the cell board for your specific class of HP
server.
• Order the appropriate HP product number for the entire amount of Instant Capacity memory
on the cell board.
• Order the appropriate HP product numbers and quantities of Instant Capacity processors for
the number of additional cores to activate on the cell board (for details about core usage
rightssee “Instant Capacity Cell Board and Considerations of Core Usage Rights” (page 67)).
NOTE: It is highly recommended that you have the same number of processors or cores and
amount of memory on all cell boards in a given hard partition (nPartition). For optimal performance,
each nPartition should have cell boards with identical numbers of processors or cores and amounts
of memory (otherwise, system performance can be unpredictable).
Rules for ordering memory help ensure that the Instant Capacity cell board matches the amount of
memory in the other cell boards in a given nPartition.
HP-UX and OpenVMS License and Support
You do not initially pay for HP-UX and OpenVMS license and support fees on an Instant Capacity
cell board.
When you acquire the usage rights for a cell board by purchasing the cell board RTU product,
there is an additional cost for the incremental HP-UX or OpenVMS license and support for each
core that is activated. That is, the HP-UX or OpenVMS license and support costs are based on a
“per active core” basis and are not included as part of the cell board RTU.
If activation of an Instant Capacity cell board does not increase the number of active cores, then
you do not have to pay incremental HP-UX or OpenVMS license and support fees.
Your system must be properly licensed for the HP-UX or OpenVMS Operating Environment (OE)
when activating the Instant Capacity cell board. You might also need software licenses for
nonproprietary software. Consult your application software vendor about licensing requirements.
Acquiring Usage Rights for Instant Capacity Cell Board
Before activation of an (inactive) Instant Capacity cell board, you must acquire (purchase, or
borrow from a GiCAP group) additional usage rights from HP. To purchase additional usage rights:
• Order the appropriate HP RTU product for the cell board for your specific class of HP server.
• Order the appropriate HP RTU product for the entire amount of Instant Capacity memory on
the cell board.
• Order the appropriate HP RTU products for the number of additional cores you want to activate
on the cell board. This number depends on several factors (and in some cases might not be
required); examine this need before ordering any cell board usage rights. For more details
about how to determine this number, see “Instant Capacity Cell Board and Considerations of
Core Usage Rights” (page 67).
