Active Memory Expansion Decision Making

Description: Start off with adequate true physical memory Not all AIX 6.1 applications/data allow effective expansion Active Memory Expansion less effective when CPU utilization is high. Be sure to consider peak workloads. Best use: Active Memory Expansion as a way to expand beyond physical memory limits Before using to reduce memory purchase, need to understand how well current and future application data compresses and how much processor resource available for memory expansion (compression/decompression) Additional processor resource part of AIX 6.1 partition and requires licensing like any other active core If unsure of your expansion value, consider purchasing true physical memory initially and then using Active Memory Expansion as a future MES order after analyzing its use.
