Hi all:

Around 1:00-3:00 in the morning, the CPU usage rate reached a maximum of 82%, OCUM sent an Alert notification, and found that the IOPS value also increased during this period, but there were no users during this period, you can ask about this situation Why? Thank you all!!

Check if there are any script, backup software, deduplication, or Snapmirror scheduled to run at 1AM
