"Had the app been as efficient three years ago as it is today, I'm estimating that about half of what was spent on hardware and related licensing and support costs would not have been necessary." So first off the software costs where far higher than the HW costs. Second, possible savings of 750k would have come at the cost of features or development time both of which have costs. If anything this just points out how expensive using Microsoft solutions can be when you need to scale. But, even still I expect over 3 years the 750k "lost" is an insignificant cost vs the cost of development and roll out. PS: Reading between the lines the HW costs where probably well under 150k. "up to 30% of 32 database cores all by themselves." |

The customer purchased IBM x460's, 16 CPU's, 64GB RAM = $225k each in 2005, right after they came out. Three required (active, passive in a cluster at the production site and one for the DR hot site). Upgrade them to dual core x3950's six months later = another 200K (or so, the upgrade was to 16 dual cores, 128BG RAM for each of the three database servers ). Plus all the odd's and ends, like 60 amp 3 phase power, 70,000 btu's of cooling, etc.
The software/licensing/support costs were because with > 8 sockets, you needed Microsoft Data Center Edition, and at that time, it came with an expensive support contract ($70k/yr).
Had the vendor been about 6 or 12 months ahead on their optimization, the 16 CPU x460's could have been 8 dual cores instead, and the 32 core upgrade probably wouldn't have been needed - or if it was, it could have been delayed until quad cores were available, the expensive OS support would not have been needed, half as many Microsoft SQL Enterprise CPU licenses would have been needed, and the 24x7 hardware maint contracts would have been half as much, etc.
