What is the maximum amount of memory and IFLs on a LinuxONE Rockhopper II?

Question

Options

• A8TB memory and 30 IFLs
• B3TB memory and 15 IFLs
• C2TB memory and 10 IFLs
• D4TB memory and 20 IFLs

• A
  88% (23)
• B
  8% (2)
• C
  4% (1)

Explanation

Option A is correct because the IBM LinuxONE Rockhopper II (based on the z14 architecture) supports a maximum of 8TB of memory and 30 IFLs (Integrated Facility for Linux processors), making it a powerful mid-range enterprise Linux platform. Options B, C, and D are plausible-sounding distractors that understate the system's actual capacity - none of those memory/IFL pairings match the documented hardware maximums for this model. The Rockhopper II was designed to offer significant scalability for Linux workloads, so lower figures like 2TB or 4TB would contradict its enterprise positioning.

Memory tip: Think "Rockhopper = Rock-solid 8 and 30" - the two numbers share no obvious pattern, so anchor on 8TB (a large power-of-2) paired with 30 IFLs, which is the highest value in all the choices, matching the system's top-tier specs.
