3.1.4Trial Capacity on Demand
Customers with CUoD featured systems must purchase the activation codes from IBM before the
The following basic rules apply for the
After the CUoD resources are activated, the customer must either buy all or part of the activated CUoD resources from IBM or return the activated CUoD resources to the system within 30 days.
Trial CUoD can only be used once.
There are several advantages to using this feature:
You can improve the response time to meet unpredictable increase in workload.
Customer can monitor the performance of the system after activating the CUoD resources before placing the order for activation codes.
It is useful when a CUoD permanent activation purchase is pending.
3.2Reliability, availability, and serviceability
Excellent quality and reliability are inherent in all aspects of the IBM Sserver p5 design and manufacturing. The fundamental objective of the design approach is to minimize outages. The RAS features help to ensure that the system operates when required, performs reliably, and efficiently handles any failures that may occur. This is achieved by using capabilities that are provided by both the hardware and AIX 5L.
The
Most firmware updates enable the system to remain operational.
ECC has been extended to
Partial L2 cache deallocation is possible.
Number of L3 cache line deletes improved from 2 to 10 for better
The following sections describe the concepts that form the basis of leadership RAS features of IBM Sserver p5 systems in more detail.
3.2.1 Fault avoidance
p5 systems are built to keep errors from ever happening. This
Reduced power consumption and cooler operating temperatures for increased reliability, enabled by the use of copper chip circuitry, SOI, and dynamic
