I use the following formula to size the minimum number of cores on replacement servers. The formula is based on "used" performance on the installed servers matching "used" performance on the replacement server. c2 = (u1)(c1)(p1) / (u2)(p2) Where c1 = # cores on the installed server p1 = "performance per core" of the installed server u1 = % utilization of the installed server c2 = # cores on the replacement server p2 = "performance per core" of the replacement server u2 = % utilization of the replacement server If consolidating multiple...
