IBM eServer pSeries 650, 670, and 690—Planning Guide for Capacity Upgrade on Demand

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.
