Active Memory Expansion Economics Three Scenarios

Share  Email

Description: Scenario A: Server has maximum possible true memory and CPU utilization relatively low. Memory limits constrain server. Scenario B: Server is not at maximum true memory and CPU utilization relatively low. Calculate gained memory: true memory x expansion factor = gained memory. For example, 96 GB true memory with a 30% expansion = 29 GB gained. Compare cost of additional true memory versus cost of Active Memory Expansion. If costs are equal, then chose true memory. But if memory expansion offers savings, then order it with an appropriate amount of true memory. As appropriate, include additional software licensing, memory activations, processor activations in the analysis. Scenario C: Server is full of smaller DIMMs, but more memory is needed. Removing smaller memory DIMMs and purchasing larger DIMMs not desirable. Analysis same as to Scenario B. Need to project an expansion factor. Active Memory Expansion Author: IBM
