Really!? You’re seeing LESS *net* host CPU usage from storing your data on a SAN with SSDs than you are with NVMe disks, for the same I/O performance?
If so, that’s fascinating and useful data. Not many of us can mount that size test system, and being much more than casually involved with NVMe (cough), that would be an interesting data point.
Then again… maybe the way our database tables are constructed, once things are set there’s relatively little I/O? (note use of word *relative*)… hot data stays hot, for example…
There should be an interesting application for storage tiering here.
Sorry… but I’m sure we all like to play architect in somebody else’s sandbox occasionally. It’s the dilettante in us.
