TCO for Oracle on POWERPosted by: Robin Webster in Infrastructure on Sep 17, 2009 |
|
The 5Ghz POWER6 processors are considerably more expensive than the 4.2/4.4Ghz alternatives and could be ruled out on grounds of cost on first inspection. I was called upon by a customer the other day to perform a total cost of ownership study for 5 years including organic growth on a IBM Power p570 system
Included in the TCO calculation were power consumption, services, maintenance, hardware and software costs. The overall result was that the IBM p570 the 5Ghz system proved the lower cost option compared to the 4.2 or 4.4Ghz. The most significant factor was the reduced Oracle licence overhead.
The higher performance rating of the 5.0Ghz core kept the licence count within the customers current licence entitlement that had been agreed with the POWER5 cores (0.75 licences per core compared with 1 per core for POWER6).

Interestingly when we looked at the p595 the 4.2Ghz processor had a higher Rperf rating such that 12 procs on the p595 at 4.2Ghz were as fast as 12 procs at 5.0Ghz on the p570. With the application tier included in the complete costing the difference between a single p595 and two p570's was minimal.
