Power Systems with POWER8 Sales Skills V1

Question No: 71

A client running Oracle databases is considering a Power solution. They want the highest level of reliability, performance, and support.

Which operating system on Power should be recommended?

  1. Red Hat

  2. IBMi

  3. AIX

  4. SUSE

Answer: C Explanation:

Businesses today need to maximize the return on investment in information technology. Their IT infrastructure should have the flexibility to quickly adjust to changing business computing requirements and scale to handle ever expanding workloads-without adding complexity. But just providing flexibility and performance isn’t enough; the IT infrastructure also needs to provide rock-solid security and near-continuous availability and while managing energy and cooling costs.

These are just some of the reasons why more and more businesses are choosing the AIX operating system (OS) running on IBM systems designed with Power Architecture庐 technology. With its proven scalability, advanced virtualization, security, manageability and reliability features, the AIX OS is an excellent choice for building an IT infrastructure. And, AIX is the only operating system that leverages decades of IBM technology innovation designed to provide the highest level of performance and reliability of any UNIX operating system.

Question No: 78

In addition to one System Node, what is (are) the minimum E880 hardware feature(s)?

  1. One System Control Unit and two I/O drawers

  2. One System Control Unit

  3. One I/O drawer r

  4. Two I/O drawers and one disk expansion drawer

Answer: C Explanation:

The IBM Power System E880 with POWER8 system node uses 8-core symmetric multiprocessing (SMP) processor chips with 512 KB of L2 and 8 MB of L3 cache per core, DDR3 CDIMM memory, dual memory controllers, and an industry-standard Gen3 PCIe I/O bus designed to use 32 lanes organized in two sets of x16. The peak memory and I/O bandwidths per system node have increased over 300% compared to POWER7 鈩?servers. The two primary system building blocks are one system control unit and one or more system nodes. Additional I/O support is provided with a 19-inch PCIe Gen3 I/O expansion drawer and an EXP24S SFF Gen2 expansion drawer. The processors, memory, and base I/O are packaged within the system nodes. The system nodes are rack based.

New POWER8 processor single chip modules (SCM) are provided in each system node. Processors are interconnected by two sets of system buses. Each SCM contains two memory controllers per processor module. Four 4.35 GHz 8-core SCMs are used in each system node, providing 32 cores (#EPBB). As few as eight cores in the system can be activated or up to 100% of the cores in the system can be activated. Incrementing one core at a time is available through built-in capacity on demand (CoD) functions to the full capacity of the system.

The Power E880 can have up to four system nodes per system. With 32-core nodes, the maximum is a 128-core system. In 2014, up to two system nodes per server are supported or a maximum of 64 cores.

The system control unit provides redundant system master clocks and redundant system master service processors (FSPs). Additionally, it contains the Operator Panel, the System VPD, and the Base DVD.

Question No: 79

A customer with AIX and IBM i based applications is considering a move to open source Linux applications on x86 systems.

Which benefit should be highlighted for the customer to stay with the Power platform?

  1. The Power Linux system is more powerful and will cost less than the x86 systems, thereby saving costs.

  2. The Power system they are running on can support the existing applications and the new Linux applications at the same time.

  3. The Power system uses Lx86 allowing Linux to run unchanged on Power.

  4. The customer can recompile the AIX and IBM i applications and continue with Linux on their existing Power System.

Answer: C

Explanation: PowerVM Lx86 (Linux only) brings new benefits to customers and application providers who want the reliability and flexibility of Power Systems in their Linux environment, yet use applications that have not yet been ported to the platform. IBM PowerVM Lx86 allows most Linux x86 binaries to run unchanged on POWER systems using translation software that translates x86.

Question No: 80

A customer states that up time is very critical in their environment. What should the IBM reseller tell the customer?

  1. IBM’s high availability solution has instant failover resulting in zero down time.

  2. IBM’s POWER8 Enterprise systems offer a fault tolerant solution.

  3. Power Systems are the most reliable non-mainframe systems.

  4. IBM POWER8 technology offers concurrent maintenance on all components.

Answer: B

Explanation: The reliability of the IBM Power Systems鈩?starts with components, devices, and subsystems that are designed to be fault-tolerant. IBM Power Systems uses lower voltage technology in the processor Single Chip Modules (SCMs) that improves reliability stacked latches to reduce soft error (SER) susceptibility. During the design and development process, subsystems go through rigorous verification and integration testing processes. During system manufacturing, systems go through a thorough testing process to help ensure high product quality levels.

The processor and memory subsystem contain a number of features designed to avoid or correct environmentally induced, single-bit, intermittent failures as well as handle solid faults in components, including selective redundancy to tolerate certain faults without requiring an outage or parts replacement.
