  C. 96GB memory
  D. High speed Ethernet adapters
  A. Large cache disk controllers

  ---

  Explanation: IBM S814 (6-core) has 18 Drive backplane with Dual raid controllers with a nice level of cache. Can attach say at EXP24S and fill the 18 internal slots

• Question 102:

  A customer running Linux with VMware on their x86 systems wants to add an S822L into the environment using a consistent virtualization technology. How can a Power option satisfy the requirement?

  A. Implement PowerVM and VMware since the functionality and management interface are shared.
  B. Implement Kimchi as the management interface to support both environments.
  C. Convert VMware to PowerVM on the x86 systems for consistency with the Power Systems.
  D. Implement the appropriate KVM base version on the Power and x86 systems.
  A. Implement PowerVM and VMware since the functionality and management interface are shared.

  ---

  Explanation: You can implement KVM base version on Power and x86 systems.

• Question 103:

  A customer plans to implement a web-based solution that requires 34 Power cores. They want to acquire a POWER8 solution with the best TCA.

  Assuming all other configuration requirements are equal, which solution provides the best TCA?

  A. OneE870
  B. TwoS824s
  C. Three S814s
  D. OneS822
  B. TwoS824s

• Question 104:

  A customer requires two local redundant VIO servers on their E870.

  What should be included with an E870 to satisfy the customer's requirement?

  A. EXP24S disk drawer
  B. Dual Solid-State Drives in the nodes
  C. Split backplane
  D. Dual SAS drives in the nodes
  A. EXP24S disk drawer

  ---

  The EXP24S is a "simple" 24-bay SAS disk drawer. It doesn't have any local SAS controller technology or PCI adapter slots. The EXP24S is configured on Power E870/E880 servers using feature code #5887. The EXP24S is two rack units (2U) in size and has two (redundant) power supplies. The 24 disk bays utilize hot-plug, Small Form Factor-2 (SFF-2) drives. Both hard disk drives (HDD) and solid-state drives (SSD) are available. The EXP24S will be pre-configured by IBM manufacturing to operate in one of the following modes:

  Mode-1 1 string of 24 disk bays Mode-2 2 strings of 12 disk bays Mode-4 4 strings of 6 disk bays

  The mode is specified using a no-charge feature code when the EXP24S is ordered. The EXP24S mode is not changeable after the EXP24S has shipped. HDD and SDD drives can be intermixed within the EXP24s, but must be on separate disk strings. For the most flexibility, Mode-4 is recommended as it provides boot support for up to four VIOS. In Mode-4, each of the disk strings will have six disk bays. This allows each VIOS to have mirrored disk drives for normal operations, mirrored drives for alt_disk_install upgrade and two spare disk bays.

• Question 105:

  What is a competitive advantage of a Power System compared to an Oracle Exadata system?

  A. Granularity of cores and memory
  B. Integration of processors and storage
  C. Availability of SSD drives
  D. Number of available cores
  B. Integration of processors and storage

  ---

  Explanation: system is the perfect integration of compute and storage in a single two-rack unit (2U) enclosure for clustered database and virtualized business applications. It is the industry's unique a Reference: http://www.oracle.com/us/ products/servers-storage/servers/x86/x4-2l-faq- 2008606.pdf

• Question 106:

  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?

  A. Red Hat
  B. IBMi
  C. AIX
  D. SUSE
  C. AIX

  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?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 107:

  A customer needs to purchase a server to run their large Tivoli Storage Manager environment What POWER8 capability should they consider compared to an x86 solution?

  A. Dual FSPs ensure system availability
  B. Active Memory Expansion
  C. Chipkill memory reduces program errors
  D. Higher system bandwidth
  D. Higher system bandwidth

  ---

  Large Tivoli storage manager requires higher system bandwidth for data transmission. IBM Power8 is the best processor to utilize the technology and provide higher system bandwidth compared to x86 solution.

• Question 108:

  What is a performance monitoring product that is available on the E880?

  A. PowerSC
  B. PowerVP
  C. PowerVC
  D. PowerVM
  B. PowerVP

  The dynamic pace of change that is encountered with today's virtualized environments and workloads require flexible infrastructure. This flexible infrastructure allows virtual workloads to be mobile and to dynamically contract and expand

  within the virtual data center as needed by the business. Performance is key to the benefit of this new flexibility introduced by server virtualization and cloud deployments which yields the benefits of consolidation, flexibility and reduction of

  risk.

  The ability to manage and monitor the performance of both the virtualized workloads as well as the physical hardware mapping is critical. IBM PowerVPTM provides the performance intelligence to make key decisions in the virtualized

  infrastructure such as VM placement and exploitation of key server resources for optimized workload performance.
