Power Systems with POWER8 Scale-out Technical Sales Skills V1

Question No: 41

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?

  1. Databases are mostly single-threaded workloads. Scale-out POWERS servers have higher clock speeds and can scale to more cores than SPARC T5 servers.

  2. 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.

  3. More threads will implicate more licensing for the database software. Less threaded processors provide a better TCO by reducing the licensing.

  4. 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.

Answer: B

Question No: 42

A customer with IBM i and AIX platforms wants to take advantage of a recently acquired XIV Storage System, TS3500 and POWERS system. They are planning to implement 10 LPARs and need to have access to the tape library for SAN backups. The customer also wants to minimize the downtime by VIO Server maintenance.

Which option will satisfy their requirements?

  1. (1) VI0 Server, LPARs using SSP for disks, and NPIV for tape library

  2. (2) VIO Servers, All LPARs using NPIV virtualization

  3. (2) VIO Servers, LPARs using vSCSI for disks, and NPIV for tape library

  4. (1) VIO Server, LPARs using vSCSI for disks, and NPIV for tape library Manage the VIO Server updates with alternate disk update method

Answer: B

Question No: 43
