consumed 999 memory days, you will need to place an order for another memory
enablement code to reset the number of days that you can request to 999.
On/Off CoD billing
The On/Off CoD billing contract requires that you report usage data at least once a month to
IBM whether or not there is activity. Billing data can be automatically delivered to IBM by the
HMC if it is configured with Electronic Service Agent™. You can also manually report billing
data through a fax or e-mail.
The billing data is used to determine the correct amount to bill at the end of each billing period
(calendar quarter). Your IBM sales representative or IBM Business Partner is notified of
temporary capacity usage and will submit an order that corresponds to the amount of On/Off
usage. Failure to report temporary processor or memory usage during a billing quarter results
in the default billing equivalent of 90 processor days of temporary capacity.
3.3.3 Utility CoD
Utility CoD automatically provides additional processor performance on a temporary basis to
the shared processor pool. Utility CoD enables you to assign a quantity of inactive processors
to the server's shared processor pool. When the Hypervisor recognizes that the combined
processor utilization of the shared pool has exceeded 100% of the original shared pool
baseline (activated CPUs), then a Utility CoD Processor Minute is charged and this level of
performance is available for the next minute of use. If additional workload requires a higher
level of performance, the system will automatically allow additional Utility CoD processors to
be used. The system automatically and continuously monitors and charges for the
performance needed above the baseline. Registration and usage reporting for Utility CoD is
made using a public Web site and payment is based on reported usage.
3.3.4 Trial CoD
Trial CoD is available for 595 servers configured with CoD resources. CoD processors and
memory can be temporarily activated using a one-time, no-cost activation for a maximum
period of 30 consecutive days. This enhancement allows for benchmarking with the activation
of CoD resources or can be used to provide immediate access to standby resources when
the purchase of a permanent activation is pending.
If you purchase a permanent processor activation for a 595 server after having made use of
the Trial CoD, that server will be eligible for another trial of 30 consecutive days. These
subsequent trials are limited to the use of two processors and 4 GB of memory.
Trial CoD is a complimentary service offered by IBM. Although IBM intends to continue it for
the foreseeable future, IBM reserves the right to withdraw Trial CoD at any time, with or
without notice.
Important: Trial CoD should not be used as part of a disaster recovery plan.
3.3.5 Capacity Backup
595 servers configured with the Capacity Backup (CBU) designation are useful as secondary
systems for backup, high availability, and disaster recovery. CBU systems are populated with
a high percentage of on demand (CoD) processors and include a specified number of On/Off
processor days that can be activated as needed for testing or failover. Capacity BackUp 595
