Scale affecting IOPS on TPC-C for same user load


#1

Why would increasing the scale of a TPC-C test increase the storage IOPS if user load remains constant?

100 scale - 4k users - 2000 scale created DBs (3 servers shared SAN array)
2100 IOPS

400 scale - 4k users - same DB
4000 IOPS

800 scale
5000 IOPS

I am collecting individual volume result to see if I can pinpoint this issue.
