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
- DAnother Absolute Host IO limit policy with additional 1000 IOPS was set on Test_LUN
