It has already been said by IBM, but obviously bears repeating... The 226GB per volume EAV limit is nowhere near the *architectural* limit of EAV--which is over 220TB per volume. IBM artificially limited the initial per volume EAV size to 226GB to ensure any production performance bottlenecks can be addressed before raising the limit to higher values.
IBM is very aware of the "airline magazine" mentality that prevails today. They realize it's difficult to be on the defensive all the time trying to explain capacity and throughput issues to ignorant people. It's better to be the ones' putting the others on the defensive.
That's why we have 64-bit processors (and not 63-bit) and a 4.4Ghz chip in the z10 (and not the 2+Ghz value we should have had if we had continued down the z9 path). I would not be surprised to see a 1TB or even 2TB EAV in the not-too-distant future.
My prediction is that IBM will continually raise the per volume EAV size to a value at or above the prevailing off-platform volume size for exactly the reasons stated...
