While we are on power issues.
I was just mulling over the following issues:
Should, one set an idle power down timeout for all your IDE
drives in the cluster?
Does spinning down an IDE drive reduce MTBF?
How much stress is really incured during spinup and/or spindown?
The logistics of this becomes important, especially when you have
hundreds of IDE drives deployed in a large cluster :)
You save power if the drive is spundown, but does the spindown/spinup
effect MTBF? If it impacts negatively on MTBF, does the power saving
outweigh the cost?
