Q21. A customer has a Power 740 with 16 cores and 64GB RAM, running an Oracle database. The server is attached to an EXP24S with 20 disks 300GB 10K RPM and has been experiencing performance issues. After an analysis there were some findings:
Average CPU usage for the database is 30% Average Memory usage is 60%
High I/O waits are being experienced, around 50% of total CPU
An Oracle sales representative ran a POC of an Exadata X4-2 Half Rack to help with the performance issues.
The performance on Exadata was better than the existing solution, so the customer called IBM, considering a migration to a new Oracle solution.
Which response is appropriate to defend the IBM solution?
A. Exadata X4-2 Half Rack has four servers with two sockets each. It should be compared with the performance of a POWER 770 which can also scale up to eight sockets. IBM can propose an upgrade scenario to even move partitions without downtime with LPM.
B. Exadata is a solution comprised of servers, disk storage, flash storage, networking and software. Your server is apparently fine, but there might be a problem with storage. IBM can propose a faster storage solution, allowing you to keep the server and optimize your costs.
C. Exadata might have run the Oracle database faster due to the fact that it is powered by Oracle SPARC T5 processors which were designed for Oracle software. On the other hand, other workloads will definitely run slower, so you should stick to the existing solution for a balanced performance across your environment.
D. Exadata is comprised of a cluster of servers connected by Infiniband. You are comparing this to a single server. IBM can propose a second server with an Infiniband network to address this issue.
Answer: B

Q25. Which statement is true regarding Power Systems being positioned as an open platform?
A. OpenStack management allows for a single HMC to provide centralized management across the whole private cloud.
B. CAPI allows clients to consolidate multiplatform workloads by attaching other manufacturer processors (like Intel or Oracle) on the servers.
C. PowerKVM allows clients to standardize on a single open source virtualization technology among RISC and x86 servers.
D. Linux on Power allows clients to transparently migrate workloads from Linux x86 servers via Live Partition Mobility.
Answer: C
