Chris, thanks for joining in, but you lost me there. What I am inferring from your response is that an individual SP in an A/P array has way more power than an individual SP in an A/A array. I.e. if one SP in the A/P array goes down scheduled or ohno, the remaining SP not only can take ownership of all orphaned LUNs, it has enough horsepower to handle all the extra load for continuous ops. Versus an SP in an A/A array which would eventually melt down under double the load.
Is that really true? If so, what's wrong with the storage guys? My understanding is that A/A arrays tend to be designed for enterprise scale, A/P for SMBs, so I'd expect the A/A arrays to have much more fault tolerance than the A/P arrays.
