In a competitive situation, a customer wants to compare virtualization capabilities of POWER8 systems and x86 systems. Which response describes a competitive advantage of PowerVM compared to VMware?

Question

Options

• APowerVM runs in a secure address space while VMware runs in application state
• BPowerVM can run dual VIO servers to provide higher availability
• CPowerVM provide higher system utilization because it is implemented in the processor logic.
• DPowerVM has the ability to virtualize memory while VMware does not.

• A
  18% (7)
• B
  8% (3)
• C
  3% (1)
• D
  72% (28)

Explanation

Recent innovations include Active Memory Sharing, which allows for the exchange of memory between running partitions. This increases optimization of physical resources similar to how CPUs are shared with Shared Processor logical partitions. It enables the sharing of a pool of physical memory among the logical partitions. One of the key benefits is that it provides the ability to configure systems with less physical memory. When a system needs more physical memory, it can be configured to grab the memory from the shared pool. Basically, this shifts memory dynamically from idle LPARs to active ones. This feature is available on AIX V6.1 and SLES 11. A VIO server must also be deployed for partitions that use Active Memory Sharing, and all I/O access needs to be virtualized by using these partitions.
