Question

A storage administrator performs a monthly performance analysis of a Dell EMC Unity XT storage array using CloudIQ insight reports. Three LUNs are set with a Host IO Limits policy. The administrator discovers that the throughput IOPS on one LUN (Test_LUN) has increased by 1000 IOPS compared to the two previous months. What is a possible root cause of the spike in IOPS?

Options

  • ATest_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set for all three
  • BTest_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set only for
  • CHost IO limit of Test_LUN was edited and the limit was increased by 1000 IOPS
