IBM Power Systems with POWER8 Enterprise Technical Sales Skills V2

Question No: 91 – (Topic 2)

Which of the following is a benefit of Power Enterprise Pools?

  1. Has no restrictions on where or how long cores and memory can be relocated.

  2. Provides automatic load balancing based on built in policies enabled in PowerVM.

  3. Provides greater flexibility to manage core and memory availability for workloads.

  4. Can use a Scale-out system temporarily in certain conditions.

Answer: C Explanation:

Power Enterprise Pools (PEP) provides the ability to move processor and memory resources from one server to another any time, with no physical movement of hardware, using easy operator commands in HMC. The PEP topology is a set of servers that is

entitled to share a set of hardware processor and memory licenses between them. This grouping and sharing allows for fast workload balancing and LPM (Logical Partition Mobility) activity while keeping overall server capital costs lower. One does not have to purchase licenses for all resources on all systems, but instead can purchase fewer licenses overall and move them when needed, to and from servers as their workload requirements rise and fall.

Question No: 92 – (Topic 2)

A customer with a Power 780 (9179-MHD) is considering a model conversion to the Power E880 (9119-MHE). They currently have Elastic COD enabled.

Which of the following steps will need to be completed for them to continue using Elastic COD on the E880?

  1. Prepay for Elastic COD usage when placing the upgrade MES order for the new E880.

  2. Reorder the Elastic COD enablement features when placing the upgrade MES order for the new E880.

  3. Reorder the Utility COD enablement features when placing the upgrade MES order for the new E880.

  4. Convert static activations to mobile activations when placing the upgrade MES order for the new E880.

Answer: B Explanation:

For POWER7 processor-based systems that have the Elastic CoD function enabled, you must reorder the elastic CoD enablement features when placing the upgrade MES order for the new Power E870 or E880 system to keep the elastic CoD function active.

Question No: 93 – (Topic 2)

A customer recently purchased a Power E870 that includes redundant Service Processors, and would like to implement dual HMCs.

What does IBM’s Best Practice documentation recommend?

  1. Each HMC should be connected to both Service Processors on a separate private network.

  2. The HMCs should share the same DHCP range.

  3. Each HMC should be managed by PowerVC.

  4. The HMCs should use the same subnet to connect to the service processors.

Answer: A Explanation:

Using a redundant HMC configuration with your service processor setup requires a specific port configuration, as shown in the figure below.

Ensurepass 2017 PDF and VCE

The HMC’s first Ethernet port, eth0, should be configured to be a Dynamic Host Configuration Protocol (DHCP) server over a private network.

Question No: 94 – (Topic 2)

A customer wants to optimize their environment.

Which of the following is true about virtualization for POWER8 servers?

  1. Adapters can be dedicated to Virtual Machines.

  2. Cores must be shared between Virtual Machines.

  3. Virtual Machines require shared memory.

  4. Virtual Machines require virtual adapters.

Answer: A

Question No: 95 – (Topic 2)

Which of the following is a feature in PowerVM?

  1. Hard capping of virtual machines

  2. Processor Micro-Threading

  3. Active Memory Expansion

  4. SR-IOV adapter support

Answer: A Explanation:

PowerVM supports Shared processor pools, which have the following benefit:

Processor resources for a group of VMs can be capped, reducing software license costs References:

Question No: 96 – (Topic 2)

Which component of the POWER8 system architecture provides improved RAS capabilities relative to POWER7 system architecture?

  1. PCIe Gen3

  2. CDIMMs

  3. N 1 Power Supplies

  4. CAPI

Answer: D Explanation:

CAPI on POWER8 systems provides a high-performance solution for the implementation of software-specific, computation-heavy algorithms on an FPGA. This innovation can replace either application programs running on a core or custom acceleration implementations attached via I/O. CAPI removes the overhead and complexity of the I/O subsystem, allowing an accelerator to operate as an extension of an application. The IBM solution enables higher system performance with a much smaller programming investment, allowing heterogeneous computing to be successful across a much broader range of applications.

Question No: 97 – (Topic 2)

A customer is considering implementing NovaLink for critical Enterprise workloads. Where will NovaLink run?

  1. On the HMC.

  2. As a job in each dual VIOS.

  3. In a separate Linux partition.

  4. As an appliance connected to the FSP.

Answer: B Explanation:

NovaLink runs inside an Ubuntu Linux LPAR (we expect to support other Power Linux distributions in the future). This is just a standard Power LPAR whose I/O is provided by the VIOS (therefore not requiring any physical I/O) with a special permission bit to enable PowerVM Management authority.

Note: It is easy to convert an existing POWER8 system to leverage the NovaLink architecture. From the HMC, simply create a new partition as you would any other LPAR, providing it with virtual network and storage through the VIOS. Then enable the new co- management feature in the HMC, and enable PowerVM management authority for the newly-created partition. Finally, boot to the NovaLink installer (network, USB, or Optical) and finish the install.

Question No: 98 – (Topic 2)

Which IBM adapter types provide NPIV capability?

  1. Fibre Channel and SAS

  2. Fibre Channel and SR-IOV

  3. Fibre Channel and Fibre Channel over Ethernet

  4. SAS and Fibre Channel over Ethernet

Answer: C Explanation:

NPIV (N_Port ID Virtualization) is an industry standard that allows a single physical Fibre Channel port to be shared among multiple systems.

Question No: 99 – (Topic 2)

Why should a customer consider the selection of POWER8 Enterprise servers instead of POWER8 Scale-out servers?

  1. PowerCare, PowerVM included on all Enterprise servers, PowerVC support

  2. Higher maximum memory, RAS, and number of cores

  3. Linux Big Endian and Little Endian support and 128GB DIMMs

  4. IFLs, PowerKVM or PowerVM, AIX, IBM i and Linux enabled

Answer: B Explanation:

Power Enterprise servers provides up to 192 POWER8 processor cores with up to 16TBs of memory, while POWER8 scale-out servers are available with up to 24 cores.

Improved RAS (Reliability, availability and serviceability): Power8 Enterprise Class Servers such as the Power System E850, E870 and E880 the PowerVM hypervisor can recover from uncorrectable errors originating in memory through the use of ACTIVE Memory Mirroring for the hypervisor. Think of it like RAID1 for hypervisor memory.

  2. 8 cores for 32-core configuration8 cores for 40-core configuration

  3. 6 cores for 32-core configuration8 cores for 40-core configuration

  4. 16 cores for 32-core configuration20 cores for 40-core configuration

Answer: B Explanation:

For POWER8 and POWER7 servers, you can make a standard request for up to 8 processor core activations and/or 64 GBs of memory and you can make an exception request for all processors to be activated and/or all memory to be activated.
