A customer is comparing a Power Systems solution with an x86 solution for big data analytics.
Which no-change IBM analysis is available to justify the value of IBM Power Servers compared to x86 solutions?

  • A. System Planning Tool
  • B. Workload Estimator
  • C. Eagle Study
  • D. Performance Navigator

Answer : B

Power Systems confidently delivers consistently high service levels across hundreds of virtual workloads on a single system.
Note: The IBM Systems Workload Estimator is a web-based sizing tool for IBM Power
Systems, System i, System p, System x, IBM Flex Systems, and IBM PureFlex Systems.
You can use this tool to size a new system, to size an upgrade to an existing system, or to size a consolidation of several systems.
The Workload Estimator (WLE) allows measurement input to best reflect your current workload and provides a variety of built-in workloads to reflect your emerging application requirements. Virtualization can be used to yield a more robust solution. The Workload
Estimator will provide current and growth recommendations for processor, memory, and disk that satisfy the overall client performance requirements.

A Power 770 MMD with two CEC enclosures 256GB of memory, and PCIe expansion drawers with SAS disk is being upgraded to a Power E870.
Which of the following is a valid process to leverage the existing client investment and maintain the existing serial number?

  • A. Remove expansion drawers.Perform an MES upgrade of the memory and processor to POWER8.Migrate disk to the E870 system nodes.
  • B. Remove expansion drawers.Add EXP24S.Perform an MES upgrade of the memory and processor to POWER8.
  • C. Migrate expansion drawers.Perform an MES upgrade of the memory and processor to POWER8.
  • D. Migrate expansion drawers.Migrate disk.Perform an MES upgrade of the memory and processor to POWER8.

Answer : D

The following features that are present on the current system can be moved to the new system if they are supported in the Power E870 and E880:
Disks (within an EXP24S I/O drawer)
SSDs (within an EXP24S I/O drawer)
PCIe adapters with cables, line cords, keyboards, and displays

Racks -

Doors -

EXP24S I/O drawers -

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. To initiate the model upgrade, the on/off enablement features should be removed from the configuration file before the MES order is started. Any temporary use of processors or memory owed to IBM on the existing system must be paid before installing the Power E870 or E880.

A customer has a 40-core E880 with 2TB of memory installed with 10 cores and 1TB of memory activated. They want to move a Linux application from their x86 environment to the
E880. The application is supported on Linux on Power and requires 8 cores and 64GB of memory.
The Linux team is unfamiliar with the Power hardware.
Which of the following should be proposed to add the additional resources at the lowest cost?

  • A. Purchase 2 IFLs and add them to the default processor pool.
  • B. Purchase an additional 8 cores and 64GB of memory.
  • C. Purchase 2 IFLs and 64GB of memory activations.
  • D. Purchase 2 IFLs and isolate them in a shared processor pool.

Answer : D

Power Integrated Facility for Linux (Power IFL) is an optional lower cost per processor core activation for Linux-only workloads on IBM Power Systems. You can activate Power IFL processor cores that are restricted to running Linux workloads.
You can use shared processor pools to limit the use of processor capacity.

Which of the following RAS features is always enabled and functional on an E870 / E880, regardless of configuration?

  • A. System auto-restart
  • B. Dynamic Processor Sparing
  • C. Dynamic Memory Sparing
  • D. Processor Instruction Retry

Answer : D

Processor Instruction Retry allows the system to recover from soft faults that otherwise result in outages of applications or the entire server.
Note: Within the processor core, soft error events might occur that interfere with the various computation units. When such an event can be detected before a failing instruction is completed, the processor hardware might be able to try the operation again by using the advanced RAS feature that is known as Processor Instruction Retry.

  • A. Rezone the SAN because the existing WWPNs cannot be reused.
  • B. Order a PCIe Gen3 I/O Expansion Drawer and relocate the HBAs into the drawer.
  • C. Move the HBAs from the 770 and install them into the E870 system node.
  • D. Order new HBAs and modify the WWPNs in the ASMI.

Answer : C

Power 770 has six PCIe Gen2 integraded adapter slots per building block, with a system maximum of 24.
Power E870 has eight PCIe Gen2 integraded adapter slots per building block, with a system maximum of 16.
A World Wide Port Name, WWPN, or WWpN, is a World Wide Name assigned to a port in a Fibre Channel fabric. Used on storage area networks, it performs a function equivalent to the MAC address in Ethernet protocol, as it is supposed to be a unique identifier in the network.
A worldwide port name (WWPN) is a unique 64-bit identifier that is assigned to a fibre channel node port, called an N_port. The storage area network (SAN) administrator assigns storage to a WWPN.
An HBA (host bus adapter) is an integrated circuit adapter or circuit board that is designed to provide physical connectivity between a computer host and storage devices or a network.
