Array A bursts every eight hours; Array B never rests; Array C is free all day. Schedule Array A's jobs for 23:00–01:00 or 15:00–18:00.

Since its load stepped up on 8 October, Array A has burst above 25,000 IOPS around 03:00–06:00, 11:00–14:00 and 19:00–22:00 on most days, likely a scheduled job such as snapshot creation. Its quietest hours fall between those bursts. Array B runs a constant 33,500 IOPS; its only recurring bump is at 21:00, on 9 of 31 days, so timing barely changes its load; avoid 21:00. Array C idles at about 90 IOPS at every hour of every day. There is no weekday or weekend pattern on any array.
