  One of the biggest challenges customers face these days when searching for the right IT solution is accurately predicting the costs/benefits to their business. With the IT landscape constantly shifting due to the explosion of data from fields like mobile and social networking, the amount of data businesses must process has grown exponentially. Finding the right approach has never been more critical.

  The Alinean tool, developed by IBM, is designed to help customers get an accurate picture of what their business would look like with an IT solution from IBM PureSystems. The customer can fill in as much or as little information as they like and the tool will use industry standards, averages, and assumptions to create an analysis of what their organization would save by shifting to PureSystems.

  The customer has complete control at all times over the level of detail they submit a report can be generated by answering as little as three basic questions such as company name, location and industry. If they want a more detailed report however, they can choose to enter information such as data servers, types of application software, and their storage requirements. With this additional information the tool can generate a richly detailed view of the specific savings an IBM PureSystems solution would provide.

• Question 7:

  What benefit is provided by connecting FPGA cards to POWER8 via CAPI instead of connecting FPGA cards to x86 via PCIe?

  A. There is no overhead from OS or drivers, providing improved response times and increased throughput.
  B. FPGA card attached via CAPI on POWER8 comes pre-installed with specific drivers.
  C. The offload processor in CAPI speeds up I/O transfers from the FPGA card.
  D. FPGA cards can be installed in PCIe or PCI-X slots on POWER8.
  A. There is no overhead from OS or drivers, providing improved response times and increased throughput.

  ---

  Explanation: When you connect FPGA card to Power8 via CAPI, no overhead fro OS or drivers will occur. IT provides improved response time and increased throughput.

• Question 8:

  A customer is running an Oracle database on Solaris and needs to replace their systems. They are considering offerings from both Oracle and IBM. Oracle is leading with M5. What advantage should the IBM reseller discuss to demonstrate the value of POWER8?

  A. Total cores on a single systems
  B. License cost per core
  C. Number of threads per core
  D. Core performance
  C. Number of threads per core

  ---

  Explanation: These organizations rely on the maximum scalability that is achieved when multi- core servers and highly threaded operating systems host middleware and applications that are tuned to take advantage of these capabilities Reference: http://www.oracle.com/us/products/servers-storage/solaris/solaris11/solaris-sparc- final-5- 1931785.pdf

• Question 9:
