Capacity Upgrade on Demand (CUoD) adds operational and configuration flexibility for IBM eServer™ pSeries systems. Available for a fee, CUoD allows customers to add additional resources as they are needed. Processors and memory can be brought online to meet increasing workload demands. If the system is configured for dynamic LPAR, this can be accomplished without impacting operations.
These features have significant value for customers who want to upgrade without disruption, enhance their system RAS (reliability, availability, service ability) characteristics, or simply grow with a finer level of granularity.
The CUoD features available for your system allow the system to be
manufactured (or upgraded in your locale) with inactive resources, such as processors and memory. The
hardware is delivered with these features built in, ready to be activated when you need them. If your
system is ordered with a CUoD feature, you can activate the feature and pay for the increased processing
power as your needs grow.
CUoD features enable you to start small, and then increase your processing capacity without disrupting
any of your current operations.
CUoD standby features are turned on with an activation code purchased as an upgrade (MES) feature.
Orders are entered through the Advanced Administrative System (AAS) by the IBM sales representative or IBM
Business Partner, just as for any other feature.
In addition to placing an order for the appropriate feature, certain system data must be
sent to IBM either
through the CUoD Web site or by using the Electronic Service Agent . After IBM verifies
that a valid order
has been placed and the necessary system data has been provided, the activation code
is posted to the
CUoD Web site and a printed order confirmation is sent with the activation code.
Transmission of the code constitutes shipping of the feature that was ordered.
This guide provides information that is needed when you are planning to purchase an IBM eServer
pSeries 650, 670, or 690 server with Capacity Upgrade on Demand (CUoD) features. Information
about managing a server that has CUoD features is included to help you to consider the
CUoD activation choices that will be best for your needs.
This document is not a capacity-planning document. It does, however, point out key considerations when using capacity-planning tools for the CUoD offerings.
