What is the maximum performance of Isilon A3GB/sF800 per node?

Question

Options

• A3GB/s
• B3.75GB/s
• C4.25GB/s
• D4.GB/s

• A
  3% (1)
• B
  93% (37)
• C
  3% (1)
• D
  3% (1)

Explanation

Option B (3.75GB/s) is correct because the Dell EMC Isilon F800 all-flash node is rated at a maximum throughput of 3.75 GB/s per node, which is the vendor-specified peak performance figure for this platform.

Why the distractors are wrong:

• A (3GB/s) is a round number that likely comes from misreading or rounding down the "3" in the model designation - the "A3GB/s" in the name is a label, not the exact performance spec.
• D (4.GB/s) is an implausible value (the decimal point with no trailing digit is a formatting error clue) and exceeds the actual rated throughput.
• C (4.25GB/s) overshoots the actual spec; this number doesn't correspond to any standard Isilon F-series per-node rating.

Memory tip: Think of the F800 as going three-quarters past 3 - 3 + 0.75 = 3.75 GB/s. The model name hints at "around 3 GB/s," but the real number is three-quarters of a gigabyte higher than that round figure.
