iSeries Capacity Planning
Capacity planning is a 'business as usual' value-add function of IBM’s sales team. Any special considerations
specific to iSeries Capacity Upgrade on Demand will be pointed out in this section. There is a comprehensive set of
tools, resources and offerings available to aid IBMers, customers, and partners with capacity planning assistance.
When doing capacity planning for models with standby processors, one must plan ahead for any potential disruptive
actions that would inhibit the full utilization of activated processor capacity. Some actions you may want to take
prior to ever activating any processors are:
- Perform any I/O conditioning (e.g., new cages, or other I/O infrastructure)
- Perform memory upgrades
- Prepare LPAR partitions
Planning Ahead
By planning ahead, customers can accommodate the growth of existing workloads as well as handle new workloads
without requiring a server outage.
Simply activating standby processors may not provide you with the full potential of capacity improvements you
require. Other components of a server affect performance and overall throughput of workloads. By planning ahead
and taking into account the complete server configuration, a customer can ensure they get the full benefit of
processor activations.
