問題文
The storage test produces a good aggregate figure when many nodes read at the same time, but one node consistently sees a much lower rate than the others. The aggregate still meets the target. Should this be accepted?
選択肢
- No, but only if that node is also slow in the compute tests, since a node that is slow in one test alone points at the storage path rather than the machine.
- Yes, because the aggregate figure is what the target was written against and a single node below the average is expected in any measurement across a large number of participants at the same time.
- Yes, but the node should be recorded as a known limitation so that users can avoid scheduling on it, since the aggregate result already demonstrates that the storage system itself meets the requirement.
- No, because a synchronized job waits for its slowest participant, so that one node will hold back every job it takes part in.
