A customer is running a large application on x86 Linux with an Oracle Enterprise database. Which of the following can be used to financially justify migrating the application to POWER8 and DB2?

Question

Options

• APOWER8 requires fewer cores to run the same workload.
• BPOWER8 Active Memory Expansion reduces the cost of memory.
• CPOWER8 cores exploit SMT6.
• DPOWER8 hardware and software maintenance costs are lower.

• A
  73% (40)
• B
  15% (8)
• C
  9% (5)
• D
  4% (2)

Explanation

Comparing performance, the 740D 3.6ghz 16 core is rated at 197.7 rPerf (SMT4) whereas the S822 3.89ghz 12 core is rated at 220.1 rPerf (SMT4) or 235.6 rPerf (SMT8). So you can get 11 to 19 percent more performance, more memory, more disk bays and PCIe slots for about 40 percent less cost. Another point to note is that the memory and I/O bandwidth for the POWER8 servers (scale out and enterprise) is significantly higher than all of the previous architectures. And there are additional follow-on savings for software licensing--for our 740D versus S822, we need four fewer cores on the POWER8, which allows for additional savings on software licensing.
