Re: Question - Your IPL Frequency

Yes - that is why we have not gone to a nightly power down, back up in the
morning.

We do use the power schedule to do the IPL on Monday morning,  Down at 5:00
AM, back up at 6:00.  We just make sure that no jobs are scheduled for that
time frame.

I agree with your boss.  Best to leave them spinning, especially on
older boxes.  We have a 620 that we dread to power fully off... Always
seem to lose at least one drive every time.  If you lose two in a RAID
set, time for a reload.  It's just not worth it with how relatively
cheaper electricity is than employee time.  Plus, wear-and-tear on
boards, power supplies, etc... It's a lot like a car - if you can get it
up to highway speed, chances are barring any huge leaks or tire
failures, it'll run indefinitely if you had limitless fuel.  Give it
taxi duty and it'll be done for a heck of a lot quicker.

We have talked about that.  We are done with daily processing at 6:00 PM
and don't need the system until 7:30 the next morning.  The boss was
concerned that the drives, if left to sit idle overnight might have
issues, and more failures.

I have not been able to convince him otherwise.
