Question 7 of 114

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?

Answer

Suggested Answer

The suggested answer is 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.

Question 9 of 114

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

Answer

Suggested Answer

The suggested answer is C.

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.
