  (4)

  disks in the CEC

  (10)

  disks in a FC #5802 (I/O drawer with disks) (12)disks in a EXP12S

  (24)

  disks in a EXP24S How many disks can be reused with the S824'? How many disks can be reused with the S824?

  A. 14
  B. 38
  C. 28
  D. 24
  D. 24

• Question 46:

  A customer needs a new server for their database currently running on a 16-core POWER7 4.1 GHz based server. Oracle has informed the customer that their SPARC T5 based servers are best suited for running databases, because the SPARC T5 has eight threads per core, while the current servers only allow for up to four threads per core.

  Which of the following statements could be correctly used to repudiate the Oracle claim?

  A. Databases are mostly single-threaded workloads. Scale-out POWERS servers have higher clock speeds and can scale to more cores than SPARC T5 servers.
  B. Oracle T5 Servers are engineered to run Oracle workloads faster. Non-Oracle workloads will run slower on their hardware due to the amount of threads.
  C. More threads will implicate more licensing for the database software. Less threaded processors provide a better TCO by reducing the licensing.
  D. The number of threads cannot guarantee better performance. Servers based on POWERS have better per core performance in benchmarks when compared to SPARC T5 based servers.
  D. The number of threads cannot guarantee better performance. Servers based on POWERS have better per core performance in benchmarks when compared to SPARC T5 based servers.

• Question 47:

  A customer has a requirement for four partitions, each with 1TB of Storage They want to put a new S814 machine in. but only have 4U available in the rack. Which POWER8 option accomplishes this?

  A. Order a 6-core machine with the Expanded Function backplane with (18) SFF SAS 283GB drives, all the drives owned by VlO Server and then allocated to each partition.
  B. Order a 6-core machine with the Split backplane, with each side having (4) 283GB drives for two partitions and two sets of EJ03 Disk Controllers each connected to a 5887 with (4) 283GB disks each for the other two partitions.
  C. Order a4-core machine with the Expanded Function backplane with (10) SFF SAS 571GB drives, all the drives owned by VlO Server and then allocated to each partition.
  D. Order a 4-core machine with the Split backplane with (18) SFF SAS 283GB drives, all the drives owned by VlO Server and then allocated to each partition.
